French artillery at the turn of the 17th-18th centuries (Historical and technical essay). Armament of armies Cannons produced since the end of the 17th century

Since this question, to be honest, is simply SICK of me, and there are a bunch of “experts” who very often poke me into land instructions on the firing range of guns and other similar issues, I decided to make a post to solve this problem once and for all.
First of all, a little theory - if you do not take fortress artillery, then a land cannon in battle encounters rather flimsy protection. These can be earthen fortifications, lunettes, barriers using wood or stone, but the distinctive property of these fortifications will be their relative low strength. That is, if these are wooden spears, then they are dug into the ground. If the stones are piled up, but not cemented, etc.
At sea, in linear battles (or in battles between fortresses and ships), cannon cores had to overcome quite serious protection in the form of the “armor” (hull) of the ship, and often this protection was multi-layered, as for example is clearly visible here:

This protection had a total thickness of 60 to 100 centimeters (that is, up to a meter). Most often, even the most powerful guns could not penetrate it, and shooting at ships essentially came down to maximum hits in the hull (if we are talking specifically about causing critical damage/sinking the ship). This maximum of hits gradually undermined the protection, potholes appeared somewhere, chips appeared somewhere, connections were broken somewhere, the wood gradually sagged and broke, most often in the area of ​​the upper deck or gun ports, and finally the critical moment came when " the armor" stopped holding.
If we talk about analogies, then perhaps the most accurate imitation of this explanation I came across in the film “Death Race” with Statham:

In the film, the role of armor is played by a 6-inch armor plate at the back of Statham’s car, which competitors shoot at with all types of weapons. Sooner or later, this plate receives critical damage and can no longer withstand hits. The meaning is absolutely the same.

Now let's move on to the numbers. First of all, we note that the Gribovalevsky land cannons could fire as much as 2-2.5 km, but absolutely no one used such a range. Why? Yes, for two simple things - there were no sights for such distances yet, and the dispersion of fire was very high. Therefore, in the Gribovalevsky instructions for ground artillery we see the following figures

Effective fire distances for guns of various calibers


If we open the English naval shooting manuals (for example, from 1832), we will see the following figures:
For long guns:
Maximum sighting range 500-400 meters (sorry, here and below I am simplifying the English yard to an ordinary meter; for those who need it, they will convert it into exact values)
Effective target firing range - 200 meters
Pistol range - 50 meters.
For carronades:
maximum sighting range - 200 meters
effective sighting range - 50 meters
pistol distance - 10 meters.
Why do the values ​​of land and sea systems differ so much? Were naval guns really worse?
No, they were no worse, and sometimes even better. It’s just that the admirals laid down such values ​​because it was not about maximum, A sighting range, and secondly, from these ranges could cause damage to enemy ships. That is, in reality, naval guns could fire much further, but the accuracy of the fire and the damage from it were very bad at distances above the recommended ones. The question is - was it possible to use guns beyond the maximum effective range? The answer is why not? For example, the accuracy of a carronade over 200 meters is non-existent. But who prevents, for example, from conducting unaimed fire with carronades not on the sides, but on the sails of ships? Nobody! The area of ​​the sails is much larger than the part of the side being hit, therefore, according to the theory of probability, such fire may well be effective. Yes, the speed of the cannonball at this distance is not enough to break through a bulwark or something wooden, but tearing a sail or knocking down a yard is quite enough.
One more thing should not be forgotten - ground artillery fires from a fixed platform (ground, fortress wall, etc.) at a target that is stationary or slowly moving relative to the gun/battery. Even the galloping speed of a horse is 15-18 km/h, in sea terms - 8-8.5 knots, that is, the speed of an ordinary frigate. But most often the cavalry goes to the battery(in naval terms - in “longitudinal fire”), and does not jump along the battery(the meaning of the cavalry attack is clear - to suppress this very battery, and not to run away from its fire). The walking speed of infantry (110 steps per minute at a step of 70 cm) is significantly lower - approximately 4.6 km/h or 2.5 knots, but again - infantry goes towards the battery, not along it.
Naval artillery has a completely different task - there the enemy moves precisely along the battery, since the movement is most often parallel relative to each other, and this leaves an additional imprint on the accuracy (or, if you like, inaccuracy) of shooting and on the effective combat distance.
Oddly enough, but land artillery, operations against ships, most often used naval instructions. This is understandable - ships, especially battleships, are a very specific enemy. And here it is necessary to introduce such a concept as the probability of hitting the target, which directly depended on the number of guns firing at the target. It is clear that an airborne salvo creates a kind of “cloud” of nuclei, which covers the target. As far as I understand, in the case of long distances this probability distribution of hits is akin to Gaussian, at short distances it is linear and uniform. That is, as is the case in the movie with Statham decisive role What matters is the number of hits per unit of time.
Now let's move from theory to practice.
The first debate on this topic arose for me a long time ago, regarding Toulon of the 1793 model. Let me remind you that Bonaparte then captured the forts of Eguiet and Balaguier, located on one side of the exit to Toulon harbor. The width of the passage from the harbor itself is 1200 meters. The question is: could the guns of these forts clearly block the exit of ships from Toulon?
The answer is obvious - no, they couldn’t. And this is even though (according to Nilus) "A 12-pound core with a charge of 4 pounds at a distance of about 300 fathoms goes deep: into the ground by 7-9 feet, into a tree by 2.5 feet, into a stone by 4 inches. 300 fathoms is about 650 m; 2.5 ft. = 0.75 m." Still, the sides of the ships are clearly not land, and we will leave what kind of tree Nilus had in mind - to the author’s conscience.
The next issue of our program was my supposedly delusional ideas of shelling the brig "Mercury" with grapeshot. And again, the author of the opus about my nonsense gave a breakdown for land buckshot (the weight of one bullet is 23 grams). Well, how many times have I said - such buckshot was never used at sea!
In the same Russian fleet there were the following types of buckshot: short-range and long-range buckshot. The charge for both buckshots is 1.64 kg. The weight of the long-range buckshot was 10.9 kg, it had 48 bullets (each weighing 227 grams). The weight of the short-range buckshot is 11.2 kg, it contains 94 bullets (each weighing 119 grams). Maximum range shooting short-range buckshot - up to 400 meters, long-range up to 700. The British and French used bullets weighing 384 and 452 grams in buckshot on 32-pound and 24-pound guns! So it’s one thing to have buckshot in a bird hunting rifle, and another thing to have buckshot on a battleship. She is also on board any small ship (for example, brig) can cause quite a lot of damage, tearing sails, breaking yards, etc.

The first fast-firing 18-pounder Mk I gun entered service with the Royal Artillery in 1904, and by 1914 it had become the standard field gun in service with British and Commonwealth armies. Some of its samples were even produced in India. The design of the 18-pounder gun was based on designs from the Woolwich plant, Elswick and Vickers workshops. The gun barrel was wrapped in wire, had a simple breech and was mounted on a carriage with a trunk. A regular shield was provided. Shrapnel was used as ammunition.

Very soon the basic model of the gun was modified. Firstly, the inner tube of the gun barrel became removable, although when this gun went to war in 1914, it was practically no different from the basic version. The return springs of the gun, which returned the barrel to its original position after recoil, could not withstand prolonged firing and broke, which turned the gun into a pile of iron. All the gunsmiths could do was change the springs, which took a lot of time and effort. This continued until a modification of this gun appeared in the army. A completely new hydropneumatic recoil mechanism was developed, which was mounted inside the existing spring housing, making the gun more reliable.


During the First World War, the gun was subjected to another modernization. The original carriage included a trunk that was suitable for horse-drawn traction. However, this trunk went under the breech, which limited the elevation angle, and therefore the firing range. The result was the 18-pounder Mk IV gun (modifications were designated by numbers). In fact, this was a new development. First of all, the Mk IV was equipped with a box-shaped frame, which ensured that the barrel was raised at a greater angle and increased the firing range, in addition, a new bolt mechanism of the Asbury model was proposed.
The new recoil mechanism, located under the gun barrel, used the free piston principle, using oil and compressed air for smoother and more reliable movement. The cradle has been changed. The result was a fully rotating gun. It not only had an increased firing range, but was also more stable and had a high rate of fire - for a trained crew, 30 rounds per minute was common.

By the time the 18-pounder Mk IV entered production the war had already ended, but it was the weapon of choice for the Royal Artillery between the wars. By that time, the gun began to be supplied not only to the troops of Britain and the Commonwealth countries. Since 1917, a large batch of these guns was acquired by the US Army. Later they appeared in Ireland, the Baltic countries and China. Most of the 18-pounder guns found their use during the Second World War, and the last gun was removed from service with the Irish Army only in the 70s of the twentieth century.

Chapter 11 ARTILLERY OF THE GRAND ARMY

GRAND ARMY ARTILLERY

1. French artillery

French artillery in the 18th century is considered by most historians to be the best in the world. In 1732, Lieutenant General de Volliers introduced a system of guns that became the most advanced in the world. It consisted of 4-, 8- and 18-pounder field guns, 24-pounder siege guns, and 8- and 12-inch mortars.

In 1776, a new system under General Jean Baptiste Gribeauval was introduced in France, which existed with minor changes until 1827.

The length of the field guns of the Gribeauval system is 18 calibers. The gap in the channel between the wall and the core was halved - from 5 mm for aviary tools to 2.5 mm, due to which the starting speed projectile and shooting accuracy. On the other hand, reducing the gaps prevented the use of red-hot cannonballs, that is, a very effective incendiary agent of that time.

The gun barrels were cast solid to avoid shells, and then a channel was drilled into them. The Aviary decorations on the trunks have disappeared. The fuses were made in copper seed rods to save the guns from the rapid flare-up of the ignition hole. Sights and front sights, previously absent, were introduced.

Field guns of the Gribeauval system

The trunnion axis was raised slightly closer to the channel axis to reduce impacts of the breech on the carriage's lifting mechanism.

Gribeauval significantly lightened the carriages and replaced the lifting wedge with a lifting screw mechanism. The front end (without a box) is made with a drawbar (instead of the previous shaft) to make it easier for the native horses.

A team of six horses carried a 12-pounder cannon, four horses carried an 8-pounder, and a pair of horses carried a 4-pounder.

To move the gun into position, Gribeauval introduced straps for servants; for the same purpose, wooden levers were inserted into brackets in the middle of the carriage. 14–15 people were enough to move a 12-pound gun in this way, even on inconvenient ground.

Designation of the main parts of the gun barrel of the Gribeauval system

Gribeauval established the composition of the battery at 8 guns of the same caliber (4-pounder, 8-pounder, 12-pounder guns or 6-inch howitzers), considering that:

1) The battery must be divided into two or four platoons.

2) To service eight guns, one company of 120 servants, which has a reserve team in the park, is enough.

3) For carts serving eight guns, one company of convoy is enough.

4) One experienced captain can command these guns.

The Gribeauval 4-pounder gun had a caliber of 86.4 mm and a barrel weight of 295 kg. Accordingly, the 6-pounder, 8-pounder and 12-pounder guns had calibers of 96 mm, 106 mm and 121 mm, and weights of about 400 kg, 590 kg and 870–880 kg. The greatest effective firing range of the French 8-pounder guns was: cannonball - 900 m and grapeshot - 500 m, and 4-pounder guns, respectively, 800 m and 300 m.

A few words need to be said about the system of the 11th year, that is, 1803. Let me remind you that Napoleon returned the country to the old calendar in 1805.

In 1803, a special commission was created in France under the chairmanship of the First Consul Napoleon. Its purpose was to decide whether Gribeauval’s artillery was still suitable, or whether it was time to change it in accordance with the newly developed military requirements. The commission created a new “Year XI system,” which, although not yet fully implemented in practice, influenced the further development of artillery. This system assumed the following.

Eliminate 4- and 8-pounder field and 16-pounder siege guns, 6- and 8-inch howitzers, and 10-inch mortars. Replace 4- and 8-pound calibers with 6-pound long 17 calibers weighing 130 cores, modeled on Prussian artillery. To replace the previous 6-inch howitzers, introduce a 24-pound howitzer with a bore length of 5 calibers and a weight of 600 pounds with a projectile weight of about 14 pounds. Adopt mountain artillery consisting of new short 6-pounder guns weighing 360 pounds (that is, weighing 60 cannonballs), 24-pounder light howitzers and 3-pounder guns weighing 160 pounds (that is, weighing 53 cannonballs).

Section of a 12-pound French cannon. The presence of a chamber is clearly visible

The fortress artillery was to consist of 24-, 12- and 6-pounder guns; 12-, 8-inch and 24-pound Homer mortars and a 15-inch “stone thrower”.

For special mobile siege artillery parks, a new short 24-pounder gun with a length of 16 calibers and a weight of 120 cores was designed.

Coastal artillery included 24- and 36-pound cast iron cannons, as well as 12-inch long-range mortars (charged 12 kg of gunpowder). The coastal cannons were supposed to accept explosive shells with thickened bottoms and spikes.

Field carriages were accepted with straight frames and a box on the front, tied and easily removed.

Gribeauval's charging box was replaced by another - with wheels rolling under the body, but without reducing the diameter of the wheels and without raising the body. The ammunition was located in special boxes that could be easily inserted and removed.

Howitzers of the Gribeauval system

There are three types of iron axles - for the 12-pounder gun and howitzer, the 6-pounder gun and for other carts. Three types of wheels were used. 3-pounder cannons and a special forge were adapted for packing, as were boxes of ammunition. Gribeauval's fortress and siege carriages were replaced by a new type of "boom carriage" with a trunnion axis height of 5 feet 9 inches (1.75 m).

Finally, Colonel Villantrois designed long 8-, 9- and 11-inch howitzers with a bore length of 7-8 calibers, firing large charges at large elevation angles. These howitzers were intended to protect coastal fortifications and bays intended to shelter the fleet, as well as for bombardment from long distances. The 11-inch Villantrois howitzer weighed 39 pounds (639 kg); projectile - 215 pounds (88 kg); charge - 60 pounds (24.57 kg). With these data and an elevation angle of 42°, the range was 5.8 versts (6.2 km).

As we can see, there were many reasonable ideas in the “XI year system”. The replacement of 4- and 8-pounder guns with 6-pounder ones (by drilling out the 4-pounder ones) was caused by the experience of the war. Thus, 8-pound guns turned out to be insufficiently mobile for horse artillery and required a large convoy, which lengthened the marching columns. And the 4-pounder guns were too weak and could not operate at long ranges. The 6-pound caliber was used by opponents - Austria and Prussia. By increasing their caliber a little, it was possible to prevent the enemy from using their shells, and at the same time it was possible to use the enemy’s shells. The experience of using 6-pounder guns captured by the French from the Austrians gave good results in terms of reality and mobility. 6-pounder guns were introduced into the French artillery and were used in the Napoleonic Wars.

The howitzers of the Gribeauval system were too short and light, quickly wore out the carriages and had poor accuracy. Their ammunition required large quantity boxes. The 24-pound howitzers were long and more weight, fired large charges, and the accuracy of shooting from them was higher. And also, these howitzers did not damage their carriages. The same caliber as the 24-pounder guns made it possible to use the same shells as howitzers if the bombs were accepted for long guns, but in practice this turned out to be impossible at that time.

The 10-inch mortar occupied a middle position between the 12- and 8-inch mortars and could replace both of them. Mountain artillery is especially necessary when crossing mountainous terrain, for example, when crossing the Alps.

Straight carriage frames were cheaper and easier to manufacture. Front boxes were already accepted by everyone in all the armies of the world by that time. Changing the design of the charging boxes increased their maneuverability and ease of delivery of ammunition to the guns. Finally, Villantrois howitzers performed well in practice - during the bombardment of Cadiz, and began good remedy for coastal defense from long distances.

But constant wars, the inability to conduct long-term and serious tests of new systems, as well as a number of other difficulties that arose in the process of using new projects in combat conditions, did not make it possible to accept the “Year XI system” in its entirety. Only 6-pounder guns, 24-pounder howitzers and a few Villantrois howitzers were accepted. The 6- and 8-inch field howitzers were slightly lengthened, following the Prussian model. The remaining guns remained in service. So the result, instead of simplification, was an even greater variety of material.

Drawing of a French howitzer

In addition to the guns French army There were also howitzers. Moreover, they were not intended for mounted fire, as in the twentieth century, but exclusively for flat fire as reinforcement weapons.

In 1812, the Grand Army was armed with three types of howitzers: the 6-inch Gribeauval system, the 6-inch “extended” howitzer and the 24-pound howitzer of the “XI year” model. Their caliber was approximately the same - about 152 mm, and all howitzers had cylindrical chambers. The 6-inch Gribeauval howitzer of 162 mm caliber had a length of 4.75 calibers. Its barrel weight was 330–355 kg, and the carriage weighed 590 kg.

"Long" howitzers were introduced in 1795, modeled on Prussian howitzers. The length of the howitzer was 6.5 calibers. There were relatively few such howitzers in the Great Army.

The 24-pound howitzer of the “Year XI System” had a caliber of 160 mm, a barrel length of 6.75 calibers, a barrel weight of about 350 kg, and a carriage weight of 573 kg.

French howitzers were transported by four horses.

During the French Revolution, one-pound guns of the Rosten system were also used. They were intended for “light troops”, had a collapsible carriage and could be transported on packs. To the trunk of a carriage with wheels large diameter shafts were attached. The gun was transported by one horse. Its caliber is about two inches, the weight of the barrel is 4.2 pounds (68.8 kg).

Gribeauval left the siege and fortress weapons of de Volliers unchanged, removing only decorations (by turning) and small chambers that did not reach the goal and made it difficult to penetrate. A short 8-inch howitzer was introduced into the siege artillery.

During experimental shooting, Gribeauval found out that the Aviary 12-inch mortars would withstand a maximum of 100 more shots, after which they would become unusable; almost a third of the bombs fired from them would break. Therefore, he proposed a relatively weighted 10-inch mortar and bombs for it with thickened walls. With a charge of 7 pounds (2.87 kg), it threw bombs up to 1,000 fathoms (2,134 m), as did the 12-inch mortar. The mortar is sedentary, with a cylindrical chamber and a retractable seed rod. Cast iron machine. The Aviary 12-inch mortars were left in service until their bombs were completely used up, but from now on their weight was supposed to be increased by 8 pounds (131 kg).

In addition, Gribeauval adopted Homeric mortars of 12, 10 and 8 inches in caliber. A feature of these mortars, proposed in 1785, were large conical chambers, which gave a lower loading density and a more favorable gas effect. The chambers merged with a cylindrical channel. The mortars used triangular lugs that connected the trunnions to the body of the mortar (the muzzle). The 12-inch Homer mortar fired a bomb at a range of up to 1200 fathoms (2561 m).

In addition to the mortars, there were also 15-inch stone throwers, but descriptions of them could not be found.

In field carriages with slightly shortened and lightweight frames, the diameter of the wheels was increased, and iron axles and cast iron bushings in the hubs were adopted. To reduce the increased rollback, the beds were curved in the middle accordingly. Strong shackles and ankle straps slightly increased the weight of the carriage. To more evenly distribute the load on both axles during large movements, traveling sockets were adopted. Between the frames diverging towards the trunk there was an inserted fire monitor box for ammunition with a gable roof and hinges on the sides for inserting levers when carrying. The lifting mechanism consisted of a board rotating on a horizontal bolt (under axles), resting with its notch on the head of a screw screwed into the uterus rotating on axles. To make it easier for the servants to move the carriage, there were hooks in the frontal part at the ends of the axles and at the trunk, which were hooked onto special straps with leather loops. For the same purpose, transverse levers were inserted into special brackets on the frames. To move the carriage, 8–11 people were required for 4-pound guns and 11–15 for 12-pound guns. For horizontal aiming, two rules were used, pushed into the clips on the sides of the pivot funnel.

When retreating and transporting through ditches and rivers, a long rope was attached to the ring near the trunk - the so-called “draw”, by which the limber was pulled. In this case, the gun could continue firing.

The howitzer carriage had a wooden axle and a wedge lifting mechanism with a horizontal screw. There were no traveling nests. Knowing from experience that howitzer carriages cannot withstand firing at elevation angles greater than +20°, Gribeauval limited this angle to +18° (and –5°).

Siege carriages had a device similar to howitzer carriages, and differed little from Aviary carriages. Siege carriages did not have traveling nests, since the guns were transported separately from the carriages on special four-wheeled drays (to transfer the guns, the drogs were removed from the limbers, like the carriages).

For fortress guns, special carriages were adopted, the frames of which, consisting of several beams cut into each other, connected by bolts, had 2 wheels on the front axle and one solid, durable one - between the frames - on the rear. The front wheels rolled when rolling back along the side longitudinal bars of a special turntable; the rear wheel - along the central grooved beam of the platform, which could rotate around the front pivot. The lifting mechanism is wedge, without screw. The height of the trunnions is about 5 feet (1.52 m), instead of the previous 3?. For coastal guns, similar machines were adopted on four wheels, rolling along the beams of a wooden rotating frame (in front there was a pin; in the back there was one solid solid wheel, moving along an arced iron strip fixed on the base).

The field limbers consisted of a fork-shaped frame connected to a drawbar, a slab with a pivot above the axle, and a crossbar or slug that supported the trunk of the gun carriage. There was no box.

The siege limbers had thick wooden shafts, tightly fixed to the axle, and did not have a slug. The charging box consisted of a long box with a gable roof, mounted on a wooden frame, with its cutouts superimposed on the rear axle with high wheels and the field front axle with a slug. Wooden partitions formed nests for shells.

A field forge on four wheels with a fur, an open forge and two boxes for accessories was added to the number of carts. Triquebals and jacks were used for moving and transporting guns.

At the beginning of the 19th century, the Prussian general Scharngorst assessed Gribeauval’s artillery as follows: “French artillery, which was the first in Europe in the previous period, became again the most advanced in 1774; It is true that the basic ideas of its design and organization were borrowed from the Prussian artillery, but they were implemented in such a way that the French guns are still not inferior to any others... everything that was borrowed received the highest possible degree of perfection. The French artillery corps took the most outstanding part in the development of artillery science and technology... when in other states artillery was a craft, in France it has already become a science... French material and French institutions now serve as examples for all other artillery.”

The main disadvantage of the French field artillery It was impossible for servants to sit on the limbers and charging boxes, which allowed only walking.

The French army also paid great attention to horse artillery.

Initially, horse companies (six 4-pound cannons and one 6-inch howitzer) were attached to foot artillery regiments. However, by order of the War Ministry of February 7, 1794, a new branch of artillery was officially created, which received a special organization. The companies were organized into regiments of horse artillery. Each regiment had 6 companies and a depot.

On April 15, 1806, a horse artillery regiment of the Imperial Guard was formed, consisting of 6 companies.

U French guns and howitzers, the date of manufacture and the name of the craftsman were minted on the torel belt. Guns cast before 1793 bore the monograms of King Louis XIV. The crown of the French kings has eight line flowers above the hoop. Arcs rise from them, which also converge under the blossoming lily.

The cannons, cast in 1793–1803, depict the monogram of the Republic, consisting of two intertwined letters RF—Republic of France, topped with an inscription. Some guns have monograms National Assembly- “AN”, as well as the image of the “all-seeing eye” and the inscription.

The cannons cast under Napoleon I are decorated with his initials - the letter “N” in a laurel wreath under the crown. In the crown above the hoop are eagles with wings raised high.

The cannons of the Kingdom of Italy (Northern Italy, Piedmont and a number of duchies) depict the iron crown of the Lombard kings with the motto “God gave it to me. Woe to anyone who touches her." The guns of the Italian kingdom differed little from the French ones, fortunately, since May 1805, Napoleon I was the Italian king. And this good king sent his troops to Russia to help the French emperor Napoleon I.

2. French Allied Artillery

A complete description of the guns of the allied countries that participated in the campaign against Russia in 1812 is a hefty volume. So I will have to limit myself to the most common systems.

The attentive reader has already noticed the discrepancy between the names of Prussian howitzers - 10-pounder and 7-pounder - with the weight of their shells and caliber in inches. This is not a typo. The fact is that in Prussia, howitzer calibers were measured by the weight of a stone (!), and not a cast iron core.

Prussian 24-lb howitzer

The Prussian cannons, cast in Breslau in 1780–1801, depict the Prussian coat of arms - a single-headed eagle with a sword in one paw and “peruns” in the other. The eagle is crowned. Above the inscription: “For glory and homeland!”

The breech bears the monogram of King Frederick with the motto: "The King's Last Argument."

It is worth noting here that the calibers of a number of Austrian cannons are expressed in the small Nuremberg scale and therefore, with the same name, are smaller than in the artillery of other countries. For example, a 12-pound Austrian is equivalent to an 8-pound French, and a 6-pound is equivalent to a 4-pound.

Since the Austrian Empire included many territories, Austrian guns were distinguished by a wide variety of coats of arms and monograms. Thus, on the cannons with the coats of arms of Bohemia, Burgundy and Lombardy, images of eagles with the order chain of the “Golden Fleece” are minted. Cannons from the time of Empress Maria Theresa adorn the coat of arms of the Duchy of Tuscany, which includes the coats of arms of Austria, Parma, Hungary, Bohemia, and Jerusalem.

The artillery of the Great Army also included English cannons. Moreover, they were not trophies of the “villain Bonaparte.” The fact is that Napoleon annexed Hanover - the personal possession of the British kings.

Accordingly, the Hanoverian cannons depict the monogram of the English king George VII with the chain of the Order of the Garter and the inscription: “Shame on him who thinks ill of this.”

Saxon 20-lb howitzer

The Great Army also included Dutch cannons, cast in The Hague in 1797. They depict the coats of arms of Flanders with the inscription “Watch, trusting in God.”

The cannons, cast in 1788, bear the coat of arms of Zealand - the “swimming lion”. On the shield under the ducal crown is the inscription: “I fight and fight out.”

The Polish cannons depict the coats of arms of King Stanislaw Augustus, Prince Sapieha, Prince Potocki, surrounded by a chain of the Order of the White Eagle with the inscription “For faith, law and flock.”

On the cannons with the coat of arms of Prince Sapieha there is a mantle, in the oval there is an arrow, around there are laurels intertwined with an order ribbon, and the title of Prince Nestor-Kazimir Sapieha: the chief chief of artillery of the Grand Duchy of Lithuania. The cannons are engraved with the motto “For Faith, Tsar and Law” and the inscription: “A citizen sacrificed me to the Fatherland.”

The cannons with the coat of arms of Count Potocki also depict a mantle, and on them there is an oval shield with a seven-pointed cross and the coat of arms of Pilyava. The laurels are intertwined with the mite of the Order of Stanislaus. On the oval is the inscription: “Count Theodor Potocki of the Crown Artillery, Major General.” On top are a helmet and a count's crown, and above it are ostrich feathers with the same cross as in the coat of arms. Above the coat of arms is the motto “For war, but not at all for civil” and the year “1767”.

French artillery at the turn of the 17th-18th centuries
(Historical and technical essay)

Part 1
Guns and ammunition for them.


Preface.

Russian artillery regular army, created by the genius of Emperor Peter I, developed under a clear and strong European influence. It is believed that the king was a great admirer of Holland and perceived a lot from there.

However, Surrey de Saint-Rémy's book on artillery, first published in France in 1697, republished in 1706, was translated into Russian in 1732. In the preface to this book, the author indicates that his work is original and that the book was then translated into a number of languages, including Dutch.

It can be assumed that the basis for regulating Russian artillery imperial army However, French developments served. This does not mean at all that before Peter I there was no artillery in Russia, or that it was something vague and amorphous, that guns were poured out as needed and as needed. Peter I simply brought order to this matter, gave the artillery harmony and clear regulations, not far behind Europe in this regard.

It seems that the description of the artillery of France at the end of the 17th - beginning of the 18th centuries is of some interest in this regard. So to speak, in order to understand “where the ears grow from” and be able to compare. And this, in turn, makes it clear that in building the Army, Emperor Peter did not blindly copy the experience of Europeans, but only used it to create Russian artillery that met the conditions of Russia.

Note that I am not using the original French book, but its translation into Russian, made by Field Marshal Count Munnich in 1732. Hence I am not able to indicate the names in the original language. The names are given as Minich translated them.

The book contains quite a lot of figures indicating the sizes and weights of products. However, it is unclear from the book exactly which units of measurement are used in the text. Either Minich changed French measures to Russian ones, or he made a translation without changing anything.
On top of that, right up to the introduction in France of a single metric system measures, which happened only at the end of the 18th century, there was complete discrepancy in this matter. Although the names of the units of measurement were generally the same, literally every province had its own pounds, feet, and inches. Worse, in the same area they could change over time.

The difference is not particularly big, but it still exists. I think that Minich did not bother with recalculations, but gives the data in French measures, leaving the reader to figure out exactly what pounds and feet the French author had in mind.

For the convenience of readers, I give sizes both in French and in our usual units, recalculating from French.

For reference:
*1 Russian inch = 2.54 cm (divided into 10 lines),
*1 French inch = 2.71 cm (divided into 12 lines),
*1 Russian foot = 0.3048 m.,
*1 French foot = 0.3001 m.,
*1 French royal foot = 0.3248 m.

*1 Russian pound = 409.51 grams,
*1 French pound = 489.502 grams,
*1 French artillery pound = 491.4144 gr.
*1 French ounce = 30.588 gr.

In addition, it is advisable to indicate the names of the elements of gun barrels:

A - the bottom or treasury with its own nail.
B - flat frieze and bottom decoration.
C - ignition field.
D- astragalus or friezes fuse.
E-first ledge.
F-flat hoop and decoration, or frieze of the first ledge.
G - second ledge.
H - dolphins or ears.
I- trunnions.
K-flat hoop and decoration, or frieze of the second ledge.
L - belt or decoration, or frieze near the muzzle end.
M-banded astragalus or frieze.
N-izlet sound.
O- islet astragalus or frieze.
P-neck.
Q - burleite or muzzle decoration, or frieze.
R-barrel.
S-shell in which the fuse.

The gun barrel is divided into three main parts, called ledges:
-brown color"first ledge" highlighted
-the “second ledge” is highlighted in green
-blue color“Izlet yadrovoy” is highlighted.

The difference between these parts is mainly in the outer diameter, and accordingly, in the wall thickness. The greatest pressure of powder gases is in the first ledge, and therefore this part of the table should be the most durable.
The second ledge experiences, in addition to the internal pressure of powder gases (which is already less than in the first ledge), also external forces, since this is where the trunnions are located, with the help of which the barrel is secured to the carriage.
This structure of the gun barrel ensures its lighter weight with the same strength in comparison with more ancient guns that had a barrel of the same diameter along the entire length.

From the author. I give these difficult-to-remember names of the elements of gun barrels so as not to obscure the text below, explaining each time what, say, “frieze”, “trunnions” or “astragalus” are. The reader himself will have to take the trouble to either remember these terms or refer to this picture every time.
And at the same time, from here the reader can learn and understand some of the terms found in military historical literature.

And further. From the book it follows that at the turn of the 17th-18th centuries in France, guns were either copper, or cast iron. There were no bronze cannons. There were attempts to make cannons from wrought iron and there were quite a lot of enthusiasts of such guns, but the first experiments were unsuccessful and at the beginning XVIII centuries, the attitude towards them was generally negative.

Attention! The text of the book is not perfect and there are mathematical errors in it. Some of them are awkward and very obvious. I have corrected them whenever possible, but the reader should take into account that the data presented in the book may differ from other sources. This is the result of either errors by the author of the book, or the result of different readings of units of measurement. In addition, the low quality of printing in some cases makes it difficult to read the numbers and you have to guess based on logic and similar data from different places in the book.

End of the preface.

Comment.
In artillery there is a term “caliber”, which indicates the characteristics of the projectile being sent, i.e. gun power. Today, caliber is usually determined by the internal diameter of the gun barrel and the outer diameter of the projectile used, and it is measured in millimeters. However, until the advent of rifled guns and oblong shells (and in England even during the Second World War), the caliber of guns was determined by the weight of the cannonball, which was placed in the barrel of the gun. It was measured in pounds.
But the caliber of mortars was measured in inches and lines, i.e. along the diameter of the bore.

From the author. A very, very inconvenient way to calibrate guns. First of all, pounds were different in different countries. Secondly, kernels of the same weight could have different diameters depending on the material from which they were made. For example, the density of the same cast iron today ranges from 6.8 to 7.3 tons/cub.m.
Hence, weighing captured, and even our own, cannonballs did not give anything in terms of answering the question - will these cannonballs fit our guns?
The solution to the problem is very simple - you need to measure the diameter of the core and compare it with the inner diameter of the trunk. This is what was done in practice. For this purpose, the artillerymen had special tools. In particular, artillery compasses and templates. In the artillery arsenals, or magazines, as they were called then, and in the shelves there were templates, i.e. wooden, copper or iron rings with handles, which were called “kugellers”. The hole of the kugeller was of the exact size, and the caliber to which it corresponded was stamped on the frame. These simple measuring instruments were used to control the size of nuclei.
I use one of the tables (page 61 of Memoria), which gives the diameters of barrels in inches and lines depending on the caliber defined in pounds, to convert the calibers indicated in pounds into millimeters that are more familiar and understandable to us.
Please keep in mind that the pounds used here are French artillery pounds (different from regular French pounds). The caliber listed in inches and lines in millimeters is only approximate and indicative.

Guns produced in the 16th-17th centuries and out of use by the end of the 17th century

De Saint-Rémy points out that at the beginning of the 18th century these cannons could still be found in fortresses, in particular in Brest and Strasbourg, as well as in the French colonies. I took the liberty of giving double numbers in the table (converting pounds and feet into our usual kilograms and meters) in order to make it easier to imagine the weight and size of the guns.

There is no information in the book about the metal from which the old type guns were made. Based on their weight, we can assume that these guns were cast iron.
The transition to a new scale of artillery calibers at the end of the 17th century was accompanied by the fact that artillery pieces have lost the proper name for each caliber.

Guns produced since the end of the 17th century

In this scale, 48 and 40 pound guns were excluded as too heavy, but having no special advantage over 33 pounders. The length of the trunks was sharply reduced. If previously the longest trunk was more than 7 meters, now the maximum length was 3.32 meters. In turn, this led to a significant reduction in the mass of the guns and an increase in their mobility while reducing the number of horses in the team.

In addition, the number of gun models was reduced from 17 to 14, and the number of calibers from 17 to 10. The latter greatly facilitated the work of ammunition supply services.

The bore of all guns is strictly cylindrical along its entire length, with the exception that in the breech of 33, 24 and 16 pound caliber guns the bore narrows somewhat and takes on the appearance of a truncated cone. This is done for a better seal. powder charge and increasing gas pressure in First stage shot.

The firing range of copper classical cannons, according to de Saint-Rémy, was:
*33-pounder gun: sighting range 600 steps, maximum range 6000 steps,
*24-pounder gun: sighting range 800 steps, maximum range 6000 steps,
*16-pounder gun: sighting range 800 steps, maximum range 8000 steps,
*12-pounder gun: sighting range 450 steps, maximum range 5000 steps,
*8-pounder gun: sighting range 400 steps, maximum range 4500 steps,
*4-pounder gun: sighting range 300 steps, maximum range 3000 steps,
*2-pounder gun: sighting range 150 steps, maximum range 1500 steps.

Copper new invention guns

As of 1706, in addition to the cannons described above, cannons of the latest type were already being cast, called in the book “cannons of a new invention (new invention).” These newly invented guns differed from the classic ones in that an oval-shaped chamber for gunpowder was made in the breech of the barrel, which ensured an increase in the powder charge in comparison with classic guns, and hence an increased firing range.

This also made it possible to make the barrel shorter and significantly reduce the weight of the gun. For example, the weight of a 24-pound gun decreased from 2.5 tons to 1.5, and the length from 3.3 to 2 meters.

The new guns were distinguished by an increased outer diameter of the first ledge because increased strength was required.

From the author. It seems that the new invention guns required more durable metal, since the problem of increasing the powder charge cannot be solved by simply thickening the walls of the breech. It was also necessary new technology drilling barrels, as well as higher quality gunpowder, which has more complete combustion, because It is quite difficult to remove unburned powder particles from the charging chamber.
Obviously, these moments predetermined that with the start of production of new innovation guns, the production of old ones was not curtailed.

4 lb. 4 / 1.97 84.2 600 / 0.295 4.8 / 1.34

According to tests carried out by Lieutenant General Mense in Flanders, the maximum firing range from cannons of the new invention with a powder charge of 1/3 of the weight of the cannonball and a barrel elevation angle of 45 degrees) was:
*24-pounder gun - 2250 toise (4386 m.),
*16-pounder gun - 2020 toise (3937 m.),
*12-pounder gun -1870 toise (3645 m.),
*8-pounder gun - 1660 toise (3235 m.),
*4-pounder gun -1520 toise (2963 m.).

At the same time, de Saint-Rémy writes that the standard powder charge of the guns was half of the maximum and the aimed firing range did not exceed 300 toises (585 meters). As the guns wore out, the powder charge had to be reduced to a quarter of the maximum and the firing range was reduced to 102 toises (200 meters). The same had to be done when reaching half daily value shots, i.e. after 40-50 shots.

From the author. This generally reminds huge difference between the technically possible maximum speed of modern cool foreign cars of 250-300 km/h and the realistically possible driving speed in the city of 60-100 km/h. Of course, there are reckless drivers who accelerate to these maximum speeds, but final result always extremely sad - the car is a pile of twisted iron, and the driver is in a cemetery. Same with guns.

De Saint-Rémy notes that in addition to standardized calibers, it is possible to find guns of larger calibers. (one of the cannons of the Strasbourg fortress has a caliber of 96 pounds), as well as cannons of intermediate calibers. These are mainly captured guns or guns cast privately.

Cast iron cannons.

It was believed that their use was no longer practical due to the poor quality of the metal, which rusted too quickly, especially from inside the barrel, thereby increasing the actual caliber of the gun. Or fistulas form in the metal, which makes shooting from cast iron guns dangerous.
Of all the cast iron cannons during this period, they were approved for use in French artillery only cannons cast at the Se-Gervais foundry, since the cast iron that is melted there is very soft and tough. And even then, only a few coastal cities and towns in the mountains were supposed to be equipped with cast-iron cannons.

From the author. I believe that the French returned to the production of cast iron cannons for reasons of economy. Copper was very expensive in those days. It is no coincidence that small denomination coins were stamped from copper and their denomination was determined by their weight.

Cast iron cannons are noticeably heavier than copper ones. If the classic 24-pound copper cannon weighed 2.5 tons, the new invention 1.5 tons, then the cast iron one weighed 2.7 tons.

The book gives the characteristics of the following cast iron cannons:

4 lb. 4 / 1.97 84.2 1300 / 0.64 ?

In addition, in January 1693, 90 cast iron cannons cast in private forges were purchased in the cities of Angoumoa and Perigio:

8 lb. 25 8 /3.93 106.0 2310 / 1.14 ?

The cost of the purchased guns was 710 livres for 36-pound guns, 573 livres for 24-pound guns, and for smaller calibers from 354 to 185 livres apiece.

From the author. So, for a general idea, so that you can understand the scale of prices in France at that time and to understand that war is a very expensive business:
The Livre was the monetary unit of France until 1795. There are 20 soldi in 1 livre (sous, salt), in 1 soldo there are 12 deniers.
Prices - pound of bread - 2-3 sous; a pound of beef or a liter of wine - 2-3 sous, chicken - 15 sous; a pound of butter - 5-8 sous, a pair of men's shoes - 3 livres, children's shoes - 14 sous; a dozen wooden clogs - 25 sous.
A worker who received a livre per day was considered a wealthy person.

One 36-pound cast iron cannon thus cost 246 pairs of boots or two years' salary of a skilled worker. But copper cannons, which were the majority, were much more expensive.

Successful tests of the purchased cast iron cannons and the depletion of the royal treasury prompted the government to order the production of another 300 cast iron cannons of some calibers for the field troops. Their characteristics are as follows:

At the turn of the 18th and 18th centuries, quite exotic guns were encountered. For example, a twin 4-pounder gun. It consisted of two barrels cast together, 5 feet 4 inches (1.65 m) long, with a common ignition channel. The cannon could fire both regular cannonballs and interconnected rods (the rods were each inserted into its own barrel, and the connecting jumper remained outside). The length of this twin ammunition is 12 feet (3.95 m) and weighs 65 pounds (32 kg).

From the author. The book does not provide other data (firing range, damaging capabilities, etc.). Obviously, this invention remains exotic, since there are few places where you can find information about such guns. I dare to suggest that one of the reasons was that it is difficult to achieve synchronization of shots from both barrels. Apparently, the paired rods flew away aimlessly or even separated from each other during the flight, or worse, damaged the barrels when fired.

There was an option in which a third barrel was located slightly higher in the hollow between the two trunks, and also an option in which the barrel was cast in an oval shape and two channels were drilled into it A. Such guns had a common charging chamber.

De Saint-Rémy writes that cast-iron semi-cartan cannons (24- and 16-pounders) can fire from 90 to 100 shots per day in the summer, and 65-75 shots in the winter. However, according to information from artillery officers, they sometimes fired up to 150 rounds per day. But this is fraught with damage to the machine and swelling of the ignition channel.
16- and 12-pounder copper cannons can fire up to 200 shots in 9 hours or 138 shots in 5 hours. But these are technical capabilities since such shooting does not leave time for proper aiming of the gun.

Ammunition

The main type of ammunition for all guns was spherical all-metal cannonballs.

The translator of de Saint-Rémy's book calls them simply nuclei.

Core. They were usually cast from cast iron. The diameter of the core should be slightly smaller than the diameter of the barrel so that the core can freely roll into the barrel without delay. For example, with a bore diameter of an 8-pound gun of 106.026 mm. the core diameter for it should be 102.36 mm according to the table.

The core hits targets only due to its kinetic energy, i.e. mass and speed.

The cost of a thousand cast iron cannonballs at the turn of the century was about 3 livres.

Hard core. It is a regular core, which is heated to a red glow over a fire before loading. Designed to create fires in a besieged city or fortress. In order to be able to use a hardened cannonball in a cannon, a castle made of crumpled clay is placed between it and the powder charge. This lock also plays the role of a wad.
The use of hardened balls is permitted only in 8-pounder and 4-pounder guns. Cannonballs of smaller calibers cool down too quickly on the trajectory and cannot ignite anything. Larger caliber kernels (12-pounds or larger) are too heavy, difficult to heat to the desired temperature, and are prone to cracking and destruction due to uneven heating.

Empty core. It is a metal cylinder with a diameter of the caliber of a gun and a length of 2.5 calibers. Part of the internal space (one and a half caliber) was filled with lead, and the rest contained a powder charge. At the end of the cylinder, which, when loading the gun, looked towards the powder charge of the gun, a hole was drilled into which a copper ignition tube filled with slowly burning gunpowder was screwed. The outer end of the ignition tube was covered with turpentine (a mixture of pine resin and essential oil).

When fired from a flash cannon powder charge the pyrotechnic composition in the ignition tube caught fire, the cylinder flew out of the cannon, and after this composition burned out, an explosion occurred.

For example, a 24-pound empty cannonball had a total weight of 79 pounds (38.32 kg), i.e. more than three times the weight of a typical 24-pound round ball. In the total weight of this projectile, gunpowder was 6 pounds (2.95 kg), metal body 60 pounds (29.5 kg), 19 pounds (9.34 kg). The projectile diameter is 153 mm, length is about 382.5 mm, wall thickness is 27 mm.

From the author. From de Saint-Rémy’s book it turns out that oblong and even explosive shells with a remote fuse existed at the end of the 17th century. Of course, this cylinder tumbled along its trajectory and flew at a distance three times less than an ordinary cannonball. The accuracy was very unsatisfactory. But such shells existed.
Along the way, de Saint-Rémy briefly mentions (p. 105) that in design these “empty cannonballs” are very similar to some land mines or “undermines” installed on the ground. Unfortunately, he does not develop this thesis and does not describe it in detail. But the conclusion is that anti-personnel mines and minefields exactly in the sense in which we understand them today, they were used in the 18th century.
But just as today they write very little and in passing about mines, so it was with them in those distant times.

Core messenger. Basically it is a means of delivering written documents to and from a besieged fortress.
This is a hollow screwed spherical core coated with lead or made of lead.

Chain core (nipple). There were several types of knipples. The simplest is two cores connected by a rigid jumper (similar in shape to modern sports dumbbells). The nipple could be immediately cast in this mold. There were options when two half-nuclei were connected by a chain. Or the half-cores were hollow, and the chain was laid in the cavities of the half-cores before firing.
In de Saint-Rémy's book, only one option is given - simply two cores connected by a chain.

Nipples are effective at relatively short distances and mainly on ships, where they are good at destroying spars and rigging. On land they were sometimes used to fire at fortified camps or approaching infantry.
The accuracy of shooting with nipples (apparently consisting of two cores with a chain) on land is unsatisfactory, and the firing range half as much as with regular cores.

De Saint-Rémy gives in his book a variant of a nipple consisting of two half-cores connected by a rigid jumper. However, he points out that this type of pin is intended for use as an incendiary projectile.

A cannonball filled with an incendiary composition (incendiary nipple). It is a nipple on rigid jumper (shown just above), The gap between the half-cores is filled with a solid rosin-based incendiary composition and wrapped in several layers of canvas impregnated with resin. When fired, the canvas ignites from the gunpowder charge, and falling near the target creates a fire.

There is an option in which an ignition tube similar to the tube of the empty core is screwed into one of the two semi-cores through a drilled hole. In this case, the nipple shell is made of lead.

From the author. De Saint-Rémy does not provide descriptions of incendiary compositions. One of the books describes that powder balls could be placed inside the train, which, when fire reached them, exploded and scattered the burning composition, thereby increasing the source of the fire.

Interesting feature. The diameter of the cylindrical part of the nipple was slightly larger than the diameter of the half-cores, due to which the nipple was inserted into the gun barrel with force. This made it possible not to use a wad, since the canvas of the nipple performed its role.

De Saint-Rémy points out that incendiary nipples and “empty cannonballs” generally did not live up to the hopes placed on them due to the low reliability of the ignition system (ignition tubes). When fired, they either did not light up at all, or, on the contrary, ignited the filling prematurely. Their use was more of a one-time or test nature.

From the author. From these lines from the author of the book (p. 106) it becomes clear why incendiary nipples and cylindrical explosive shells, although they existed at the turn of the century, are little known and are not mentioned at all in most historical literature. Large weight, short firing range, unreliable operation, and difficulty in manufacturing did not contribute to their introduction into artillery practice.
The use of empty cannonballs generally posed a danger to the guns. Often, the pressure of the powder gases during a shot squeezed the ignition composition inside the projectile, which led to the rupture of the projectile in the barrel.
These shortcomings will be eliminated much later.

Modern military historical literature often mentions hollow cores filled with gunpowder that explode at the target. They are usually called bombs and grenades. However, if we rely on de Saint-Rémy’s book, then in France at the turn of the 17th-18th centuries the guns did not have such ammunition.
Bombs were used only in mortars, and the bomb's fuse tube was ignited separately before firing. And the core was inserted so that the ignition tube looked not in the direction of the powder charge, but in the opposite direction,
De Saint-Rémy calls grenades similar products, but which were used in fortresses for throwing them into the ditch by hand in order to destroy enemy soldiers who had penetrated the ditch and which could no longer be removed from cannons and rifles.

Kartuz, Its varieties are called - cartouche, garguzh, gargush, garguss, buckshot.
Garguzh (gargush, garguss) is a cap made of canvas. It is a fabric shell inside which a sample of gunpowder is placed and a core or lead bullets can be placed.

Kartuz (cartouche) differs from garguzh in that it is made of parchment or multi-layer paper. It can also contain only gunpowder or, in addition to gunpowder, also a core or lead bullets.

Cartuses made of tin and wood are called, respectively, “tin buckshot” and, respectively, “wooden buckshot.” They are necessarily equipped with a cannonball or lead bullets.

From the author. From here the origin and essence of the term “buckshot” (in modern spelling - buckshot) becomes clear. Buckshot is an artillery shot (that is, a set) which necessarily includes a certain number of ready-made destructive elements (lead, cast iron bullets, nails, metal fragments, etc.). When fired, the destructive elements fly out of the barrel in a diverging beam and hit enemy personnel.
We are used to calling only the round bullets themselves buckshot, but it turns out that this is not so. Bullets are just an element of a grape shot.

Along the way. Gunners call a shot both the very phenomenon of the ejection of a certain projectile from a gun, and the set of products for producing this ejection.

Caps made of parchment are considered the best because, unlike canvas and paper, parchment only curls when there is a flash of gunpowder, but does not catch fire and does not leave smoldering scraps stuck to the barrel walls and does not require cleaning the barrel (boiling) before each new loading. When using parchment caps, it is quite enough to clean the barrel (ban) only after three shots.

Reference. Parchment - thoroughly cleaned and degreased thin leather. It was used before the invention of paper, and partly later for writing (documents, books, etc.).
End of help.

The advantage of a parchment cap over a tin and wooden one is that there is no problem of removing a spent cap from a cannon and, moreover, it does not require skilled labor for its production.

The diameter of the cap is equal to the caliber of the gun.

The length of a cap made of parchment, paper or canvas, depending on the mass of the gunpowder charge, reaches six calibers if the cap contains a cannonball or bullets, or four calibers if the cap contains only gunpowder.
The length of a cap made of tin or wood is up to three calibers, of which one caliber is reserved for gunpowder, and two calibers for buckshot.

Cartridge loading is used in cases where hasty shooting is required and it is not possible, for this reason or due to weather conditions, to carry out the usual standard loading of guns (filling gunpowder into the barrel using a shotgun (schaufell), compacting using a hammer, inserting a wad and a cannonball or buckshot).

From the author. Please note - at the beginning of the 18th century, the main method of loading cannons was still pouring gunpowder into the barrel using a special spoon (shuffle).
Cartuz loading, according to the author of the book, is a necessary measure when shooting hastily or shooting in bad weather conditions (strong wind, rain, snowfall). Obviously due to the fact that after a shot, smoldering remains of a textile or paper shell may remain in the barrel bore.

Various sources provide drawings of caps that differ from those shown by me. I don't dare argue about this. I am making reconstructions of caps based on the drawings given in de Saint-Rémy’s book. It is very possible, and most likely, he will not The goal was to show in the book all the possible options for caps that could exist in different countries.

Unfortunately, de Saint-Rémy does not explain how, when fired, the fire from the ignition channel of the gun reached the powder charge in a wooden or tin cap. It is not advisable to make a hole in the cap in advance, since when loading it is almost impossible to align the channel with the hole. Obviously, the hole was made with a wire seeder.
Also, the author does not explain how, after firing, the empty wooden, and especially tin, cap was removed from the cannon barrel. The latter is especially difficult, because... when fired, it resounds and is pressed tightly against the walls of the barrel.

Buckshot.

From the author. Although wooden and tin caps are called buckshot above, there are Also, buckshots are, so to speak, “capless”. Such buckshot is inserted into a cannon instead of a cannonball when it is necessary to hit a mass of infantry at a relatively short distance (up to 100-200m). I found it more convenient to separate these products into a separate type of cannon ammunition.

The buckshot is round and oblong.
Designed to defeat enemy soldiers at close ranges. It is a kind of projectile that has a wooden pallet as a base with a diameter equal to the caliber of the gun. A cannonball with a caliber smaller than the caliber of a cannon is placed on it. The core is lined with lead bullets. To hold the core and bullets on the pallet, they are filled with pine resin or tar (tar with resin, resin with lard, tar with lard and soap).
The projectile is given the appearance of a truncated cone one and a half caliber long
To strengthen the projectile and maintain its shape at high air temperatures, the so-called. shirt, in other words, a canvas shell is glued on.
Caps of this type are preferable for ship guns, since they have a double effect - destruction of ship sides and damage to personnel.

De Saint-Rémy describes a simplified method for preparing such buckshot. A cannonball with a caliber smaller than the caliber of the cannon is taken, dipped in melted resin, after which the cannonball is rolled over a layer of lead bullets. After the bullets stick to the core from all sides, all this is placed together on a wooden pallet with the diameter of the gun's caliber, the bullets and resin that exceed the caliber are removed, and the resulting projectile is inserted into the gun.

Buckshot grazdovik (buckshot in the form of a grape brush).
Designed to defeat enemy soldiers at close ranges. It is a kind of projectile that has a wooden pallet as a base with a diameter equal to the caliber of the gun. A wooden rod the length of the projectile is embedded in the pallet. Lead bullets are placed around the rod. To hold the bullets on the pallet, they are filled with pine resin or tar (tar with resin, resin with lard, tar with lard and soap).
The projectile is given the appearance of a truncated cone one and a half to two calibers long.
To strengthen the projectile and maintain its shape at high air temperatures The resin projectile is wrapped with twine, from which a mesh is formed. The outside of the mesh can be covered with glued canvas.
As soon as this projectile leaves the bore, the bullets fly forward in an expanding beam.

The book also states that for shooting at close ranges, lead bullets, nails, broken chains, and various metal fragments can be placed in the barrel instead of a cannonball.

From the author. The literature describes many variants of buckshot. However, some of them refer either to other times or to other countries. I limit myself to the types of buckshot described in de Saint-Rémy's book. I’m not sure that he described all the types available at that time in the French artillery, but I do not think it is possible to expand this list, since it is easy to mislead the reader as to where and when certain types of buckshot were used.

At the same time, I would like to describe one more ammunition, which does not relate to cannon ammunition, but is described in the book. It is called "musketeer buckshot" or "musketeer buckshot". It is a musket bullet, which is tied to a paper bag with gunpowder by its sprue. The length of the pouch is determined to be 4 musket calibers. De Saint-Rémy emphasizes that after the bullet is cast, its sprue is not removed, but is used to connect it to the musket's powder charge.

From the author. De Saint-Rémy speaks of Musketeer's buckshot as a recent invention and notes that when loading the gun, the far end of the casing is bitten off, gunpowder is poured into the barrel, and the bullet and paper are sent after. The paper shell plays the role of a wad. In the text, he calls this product a cartridge and notes that this significantly speeds up the loading of the gun. Obviously this product was improved later. They began to use the bullet without a sprue and placed it in the bag itself.

Thus, the introduction of a paper rifle cartridge into practice should be dated back to the end of the 17th century. At least in France.

Thus, at the turn of the century, French guns were used:
* ordinary all-metal spherical cannonballs, which were fired both cold and hot,
* explosive cylindrical shells ("empty cannonballs"),
*messenger kernels,
* chain cannonballs (nipples), which could be equipped with incendiary compounds,
*various types of grapeshot shells.

Ball-shaped explosive cores were not used in cannons.

Note. All books on the history of artillery say that initially artillery used powder pulp, and then they learned to granulate gunpowder. And they say fine-grained gunpowder was better suited for guns, and coarse-grained gunpowder was better suited for cannons and mortars. So, they say, since then only coarse-grained gunpowder has been used in artillery.
I don’t presume to argue on this score, but in de Saint-Rémy’s book we find that in 1685, Marc de la Fresiliere conducted a series of experiments with various gunpowders and discovered that a significant part of the large powder grains flew out of the cannon barrel without even igniting, then how small grains burn completely. A charge made from fine-grained powder provides a greater firing range than one from coarse-grained powder.
Based on the results of the experiments, it was decided to produce medium-grain gunpowder, which is equally suitable for muskets and cannons.
End note.

Production of cannon firing.

The gun crew (in modern terms) of 12-24 pound guns consists of two gunners and six gundlangers.

The first gunner (on the command post diagram) is located to the right of the cannon. He carries a natruka (vessel) with seed powder and two pickles (knitting needles for cleaning the gun's ignition channel). His main responsibilities include filling the gun with a powder charge using a shuffle and filling the seed powder into the gun's ignition channel.

The second gunner (in the CL diagram) is located to the left of the cannon. He carries with him a stick (a pole with a burning wick at the end) and a leather bag for gunpowder (the bag is called the captain's armus). His main responsibilities are delivering a powder charge from a small powder magazine, pouring it into the chuffle held by the first gunner, and firing a shot on the orders of the commissar.

Gundlangers are positioned in threes on the left and right sides of the cannon.

The order of loading the gun calibers 12 - 24 pounds:
1. The first gundlangers (1p and 1l) ban the cannon with a bannik, after which the third left gundlanger (3 l) inserts the primer into the ignition channel of the gun and takes the shuffle.
2. At this time, the second gunner (KL), accompanied by the third right gunner (3p), brings a bag of gunpowder from a small magazine, which he pours into the shuffle held by the first gunner (KP).
3. The first gunner (KP) pours gunpowder into the cannon.
4. At this time, the second gunner (KL) puts the leather bag in a safe place and prepares the coat.
5. The second right handlanger (2p) puts a powder wad into the cannon.
6. The first gundlangers (1p and 1l) put the hammer into the barrel together and give them 8-10 blows to the wad.
7. The second left handlanger (2 l) rolls a cannonball into the cannon.
8. The first gundlangers (1p and 1l), together with a hammer, push the cannonball deep into the trunk.
9. The second right handlanger (2p) puts a wad of cannonballs into the cannon.
10. The first gandlangers (1p and 1l) together insert a hammer into the barrel and apply 4 blows to the wad of the cannonball.
11. The first ganglangers (1p and 1l) take the levers in readiness to insert them between the spokes in front of the wheels to turn the gun left or right in the direction of the target.
12. The second ganglangers (2p and 2l) take the levers and stand behind the wheels in readiness to move the cannon forward to the loophole.
13. The third gunlangers (3 l and 3 p) with levers are located at the rear of the machine, ready to turn the gun to the left or right.
14. The first gunner (KP) removes the priming agent from the ignition channel and pours seed powder into it from the powder. He also uses a lever placed along the rear wheel to fix the position of the gun.
15. The second gunner (KL) holds his pistol with a burning fuse in readiness to fire a shot on the order of the commissar.

The order of firing a shot.

After loading the gun and installing it in place, it is aimed at the target. To do this, according to the commands of the commissar, who places a quadrant on the barrel, the second gunlangers (2p and 2l), acting with levers and wedges, give the barrel the desired elevation angle. At the same time, the third ganglangers (3p and 3l), again at the commands of the commissar, standing at the trunk of the machine and using levers, aim the cannon horizontally.

At the command of the commissar, the second gunner (KL) touches the burning fuse of the gun to the fuse of the cannon and fires a shot. The process of loading the gun is repeated.

From the author. The staff of officers on the battery is very unclear. From the book it follows that the battery is commanded by a commissar (Komi sar - in the spelling of 1732). He is assisted by two provincial commissioners, one ordinary and one extraordinary commissioner. There are a total of five officers on the battery. And there are six guns on a standard battery. It follows from this that when firing, the commissars move from gun to gun, and do not each command one gun, as is done in mortar batteries.

Fully machined, copper plated and blackened cast guns made Dmitry Shevelev, gold champion of the world and Russia in ship modeling. The author has his own outstanding style, his works are distinguished by historical authenticity, artistic taste and the effect of antiquity.

To cast the guns, a dental alloy with a melting point of 105 degrees is used, then the casting is mechanically processed on a lathe, a channel is drilled, brushed, copper-coated and only then blackened. The process is not easy, but the result is amazing. There’s no need to even stutter about historical authenticity; a mosquito won’t hurt your nose. The master model of this gun was made according to drawings from the monograph Le Cygne by the French publishing house Ancre.

Technical characteristics of the gun:

  • length 59 mm; - scale 1:48;
  • caliber 8 pounds;
  • channel diameter 2.2 mm;
  • France, 1806;
  • initial development for the Le Cygne brig model. Requires 2 pieces.
The price of the product is quite high, but these are tools for which no shame at any price. We are proud the fact that we can offer work Dmitry Shevelev.
