Simply bomb!
The first large-caliber European bombards were assembled from square iron rods forged together, then bound with iron hoops for strength. However, they soon learned to cast them from bronze and make them disassemblable. The illustration on the left shows a bombard that can be disassembled into two parts (indicated by the sockets for the levers), and to the right, a similar one, cast in one piece.

"Then the inhabitants rushed to the fortress walls, but saw not a single bulky weapon, usually used in sieges, in the French camp. After a second, also less-than-accurate volley—the cannonballs struck the wall, causing it to crack—the besieged realized that the noise and cannonballs were coming from long chimneys lying on the hill, with clouds of smoke billowing above them. Horror gripped everyone, and the women rushed to the church, begging God to protect them from this satanic invention.
Thus, in the wars waged by the Western countries, the first cannon shot was fired."

The French She-Wolf by Maurice Druon




Stories about the old days weapons. First of all, let's point out that by the mid-15th century, not a single battle took place without the use of firearms. And the first time cannons were fired in Europe was during the Battle of Crécy in 1346 (as reported by the historian Froissart, who, admittedly, was eight or nine years old at the time). It's understandable that modern historians want to gain as much knowledge as possible about any historical period preceding our time. But this is not always possible, primarily because we lack the corresponding written sources. Although, in fact, artillery The tools of that time have survived to our era.

However, in the field of military affairs, weapons, and ammunition from the late 15th and early 16th centuries, there is a beautifully illustrated manuscript compiled by Bartholomeus Freisleben (an armaments specialist) in the service of the Holy Roman Emperor Maximilian I (1459–1519). This manuscript was called the "Book of Armaments," and it contains numerous beautiful color illustrations. Maximilian I sought to strengthen his army and therefore ordered Bartholomeus to compile an inventory of everything contained in his arsenals, in order to have an accurate picture of his military might.


What did the first arquebuses of the early 16th century look like, for example? Just look at the page of the "Book of Armament." And who's firing? A landsknecht of Emperor Maximilian I, of course... Illustration from the "Book of Armament" by Bartholomeus Freisleben. Circa 1502. Bavarian State Library, Munich.

The manuscript is exceptionally richly illuminated, which is not surprising, as it was compiled for the emperor, and its design was carried out by the imperial court artist Jörg Kolderer (c. 1465–1540). It is believed to have been created in 1502. It is quite possible that this is a copy of the original, which sometime in the 16th century came into the possession of the free imperial city of Ratisbon (now Regensburg). There, the manuscript, although unfinished, was bound and added to the city library's collection. In 1812, it was transferred from Regensburg to the Bavarian State Library, where it remains today. Needless to say, this is a valuable source and the riches of studying it. We will now explore some of its illustrations, which will allow us to be transported vividly back to that distant era!

By 1502, artillery had already developed sufficiently and eventually began to be divided into siege and field artillery, and the latter, although initially a novelty, showed itself very well in the battles of Formigny and Castillon in 1450, that is, already a hundred years after its first appearance.




The most common weapons of the 15th century were the multi-barreled ribaudequin, a primitive machine gun; the wogleur, a cannon used in field combat and therefore mounted on wheels; and the heavy, fixed bombard. All weapons are from the Museum of Medieval Warfare at Castelnau Castle (in the French commune of Castelnau-la-Chapelle in the Dordogne department).

But siege artillery played a more important role at that time, as its powerful weapons were used to enforce royal order in the country and to crush the walls of feudal castles. It's no surprise that the last time a wheeled siege tower was used in France was in 1356, although missile engines remained in use for somewhat longer, until the middle of the following century. The power of siege artillery during that period is illustrated by the following fact: with the help of artillery, sixty fortified castles were taken in just sixteen months, from 1449 to 1450.

These were enormous barrels of thick bronze, held in place by iron hoops and mounted on wooden carriages without wheels. Each of these monsters required a dozen horses to transport, and two dozen soldiers to set it up, aim it, and load it. Each barrel was placed in a sort of box made of thick wooden beams to protect the crew in case the muzzle ruptured.

This is how Maurice Druon described these guns in his novel “The French She-Wolf” from the “Accursed Kings” series.

Also present is a swab and a coil of rope wick. Illustration from the "Book of Armament" by Bartholomeus Freisleben. Circa 1502. Bavarian State Library, Munich.

Incidentally, the very first treatise on artillery was written in France in 1430 and had the telling title "Book of the Secrets of Artillery and Gunnery." However, the oldest of the manuals was published eighty years before the French edition in German, and was called "Method of Preparing Gunpowder, Loading Cannons, and Firing."

Historians note that the French artillery of the 15th century was probably the most organized and numerous for that time. It was commanded by the Bureau brothers, who were "Commander-in-Chief and Inspector of the Royal Artillery". Moreover, at the same time, the artillery of Mehmed II destroyed the walls of Constantinople in 1453, and along with them, buried the centuries-old Byzantine Empire.

The Duke of Burgundy, Charles the Bold, also considered it "necessary for his honor" to have the most powerful and numerous artillery. And he was right! At the Battle of Brustem in 1467, his light artillery was able to crush the eighteen thousand-strong army of Liège without resorting to cavalry. Interestingly, even then, it was common practice to give large guns their own names. For example, his guns "Shepherd and Shepherdess" and "Four Sisters" were well-known, and we know about them because they were among the spoils of war.


Another collapsible bombard and mortar—a short-barreled weapon that fired high-angle fire. Illustration from Bartholomeus Freisleben's "Book of Armament." Circa 1502. Bavarian State Library, Munich.

How such bombards were fired is well described by the same Maurice Druon:

The bombardiers lit coals in braziers near each bombard, where iron rods were heated until red-hot. They then began loading the bombards through the muzzles: first, they poured gunpowder with wrought iron scoops, then added tow wads, and finally rolled a large stone cannonball, weighing about a hundred pounds, down each barrel. Then they poured a small amount of gunpowder into a recess in the breech of the bombards, connected through a small hole to the charge inside the barrel.

Trunnions—cylindrical axles on gun barrels for vertical aiming—appeared around 1480. Interestingly, this ingeniously simple invention was first mentioned around 1400, but it took a full 80 years for it to become truly widespread. However, much depended on technology. As soon as cannon barrels were cast, trunnions appeared almost immediately. However, this improvement necessitated the abandonment of the practice of breech-loading large cannons, as it became impossible to securely fasten the "chamber" to the rear of cast guns.


The 1502 field gun already had trunnions on its barrel. The gun carriage was single-beam, resembling a tuning fork. Illustration from Bartholomeus Freisleben's "Book of Armament." Circa 1502. Bavarian State Library, Munich.

Moreover, advances in gunpowder production, which now became granular and therefore more powerful, meant that the previously removable breech could no longer withstand the force of a shot. However, cannons still existed whose barrels were secured in a wooden deck with a vertical screw at the rear. The deck was raised (and lowered!) by a rack and pin and secured to the rear of the gun carriage on two arches with holes for the mounting pin.

Soon, the Europeans started casting cannons en masse, but the British lagged behind in this, and in 1475, during the invasion of Edward IV into France, their guns were still loaded with interchangeable chambers from the treasury, and transported them on special carts.

But Charles VIII succeeded "to plunge Italy into horror" The mere sight of his 140 large-caliber guns was enough to impress. His successor, Louis XII, managed to transport 60 heavy cannons and another 500 light guns across the Alps in 1507, manned by 720 gunners.

In Austria, cannon casting developed in Innsbruck, where the industrialists Silos and Endorfer were engaged. In fact, beginning in 1485, under Emperor Maximilian I, they began casting cannons with very rich decoration, images of which, fortunately for us, were included in his "Buch der Arme" (Book of Armament). So, even then, Germany possessed the best artillery of its time.

True, at first, each craftsman cast a cannon... of his own caliber. Because of this, each cannon, and consequently each cannonball, had to be assigned a unique number! Clearly, someone was bound to find this situation intolerable, and... there was one!


Legend has it that this unusual cannon was crafted in the late 16th century for the wedding of Frederick I, Duke of Württemberg. However, the wedding never took place, and over the years the Duke fell deeply into debt. Toward the end of his life, he became fascinated with alchemy and the search for the Philosopher's Stone, hoping to acquire enough gold to pay off his debts. The decoration on the barrel of this cannon can be viewed in this light. It depicts Frederick himself in the breech alongside the four elements of nature, controlled by alchemists. The dolphin-shaped handles are adorned with embraces of male and female couples. According to legend, this symbolizes the Duke's wedding, but the men's faces do not resemble his portrait. Rather, this decoration should be interpreted as a depiction of an alchemical wedding: the meeting and merging of two complementary opposites. And from their union is born... a snake, which crawls along the cannon's twisted barrel and is usually associated with the Philosopher's Stone. Barrel caliber: 125 mm. Barrel length: 4,19 m. Weight: 2545 kg. Army Museum, Paris. Photo by the author.

It was Emperor Charles V who ordered the caliber of all cannons cast in his kingdom to be fixed within a uniform system of measurements. As a result, in 1535, Spanish foundries in Málaga finally produced the first series of four cannons firing cast-iron balls weighing 40, 24, 6, and 3 livres (a unit of weight derived from the Latin pound). Now such cannons had to be cast throughout the empire, and they were, although it wasn't until the end of the century that the old, "non-caliber" cannons were completely phased out.


At that time, bombard cannonballs weren't cast yet, but rather hewn from stone. The courtyard of Český Krumlov Castle. Photo by the author.

Moreover, giant cannons were now completely abandoned. A cannon with a caliber of 180 mm and a ball weight of 20 kg was now considered heavy, weighing 4250 kg. A large culverin weighed 2800 kg, fired an 8 kg ball, and had a caliber of 120 mm. A medium culverin had a caliber of 60 mm, fired a 1,5 kg ball, and weighed 1200 kg. A mortar had a caliber of 350 mm, a ball weight of 50 kg, and weighed 3000 kg. Incidentally, as early as 1550, gunpowder bombs with a fuse were invented for mortars, exploding upon hitting the ground.


The "Pumhart von Steyr" (Styrian Cannon) is the largest known cast-iron bombard. It weighs approximately 8 tons and is over 2,59 meters long. It was made in the early 15th century and, according to modern calculations, could fire a stone cannonball with a diameter of 800 mm and a weight of 690 kg a distance of approximately 600 meters. To achieve this, it had to be filled with 15 kg of gunpowder and tilted at an angle of 10°. Museum of Military Technology, Vienna

Making a model of a medieval cannon, say, the Pumhart bombard or the Rhodes mortar, won't be difficult, since we'll be making it out of paper and coffee stirrers. But before we start making the barrel, we need to find the cannonballs. Wooden balls of varying diameters, sold in sets at Leonardo stores, are ideal for this purpose.

Having collected at least four cannonballs to pile up neatly next to the gun, we roll a paper tube the same diameter as the cannonballs. The tube shouldn't be too thin, to avoid warping, and not too thick, as that's unnecessary. Next, glue coffee stirrers to the outside of the tube, one after the other, in two staggered rows, using PVA glue. Then, cover the barrel with two more layers of paper, making sure to keep it as even as possible. Insert two cannonballs into the barrel to prevent warping as it dries, and... now we need to wait until our construction is completely dry.

The edges are then sanded, and the barrel itself is covered with 2-3 mm thick strips of paper from quilling kits. Since guns of the time had a composite barrel, and the back was often narrower than the front, an empty plastic lipstick cap was glued to the back, also covered with paper for the purpose. A touch hole was drilled in the very back of the cap.

The end of the barrel bore is decorated with small cardboard squares of appropriate width, which imitate the iron bars from which bombard barrels were forged at that time.

The gun carriage is very simple. Two "boxes" made of cardboard, covered with strips of veneer. They are connected by "beams" made of four sticks glued together, threaded through their walls.

The cannonballs for our gun will also need to be painted with acrylic paint to match the limestone color, as they were made of stone at the time. The cannon barrel is glued to the gun carriage. You can stack the cannonballs in a pile (or just shove one down the barrel!), and our medieval bombard is ready. Now, think of a stand for it and make it yourself…

    just like the real thing... even a little unexpected!
    a good example to repeat, and if before this you tell the "little one" a story about what happened and how... thank you!

    Such mortars fired not only stone, but also cast iron cannonballs and gunpowder bombs, and were used even in the middle of the 19th century.

    By the way, two galiots with bombard-mortars are well described by the same Captain Hornblower in his 1812 campaign as a commodore in the Baltic and his participation with the Russians in repelling the siege of Riga by Napoleon... in itself an interesting and lesser-known page of history, since along with the attack on Smolensk-Moscow (the textbook one), there was also an attack on Riga-Petersburg...

    Hey people! All about guns made of iron, copper, cast iron! What's so much fiction, no imagination? But our ancestors had a more playful and "imaginative" mind! They were funny guys... not like today's boring IT specialists! Historical grandfathers cheerfully and humorously invented and created "leather", wooden, bamboo, "earth" and, even, ice and paper guns! 1. "Leather" guns... in the 17th century Sweden was a small and poor country, but the king (August, I think... that's the nickname!) wanted to fight! How could it be otherwise? "The boys" (neighboring kings) will not understand and will not respect! Tilka, that's the problem... there were too many pennies in the treasury... not enough! Like a vulgar alcoholic: you've still got enough for a bottle, but you're already running out of food! Back then, fighting without artillery was considered improper, but the gun makers of the time wouldn't let the then-Swedish kingpin go on credit! But they say "necessity breeds invention"! So, those lads, under the thumb of a kingpin, cracked a joke... they invented "leather" cannons! "Leather" is in quotes because only part of them were leather; the rest was copper liner, hemp rope, and iron hoops! Still, the cannons turned out light and cheap, albeit short-lived, and they only fired buckshot! But it became possible to save money on snacks!

      Sweden never had a king named Augustus. Gustav II Adolf's army, however, was one of the finest in Europe, with artillery to match. Gustav Adolf used leather cannons, developed by Swiss and Austrian engineers, not out of poverty, but to give his artillery mobility. The leather cannons were quickly replaced by the bronze 3-pounder regimental cannon.
      And it wasn't only the Swedes who used leather guns.

    2. WOODEN CANNONS! Yes, that's right! History knows not only the wooden ruble, but also wooden artillery! And it's hard to say who invented it! They fired from "wood" in China, Japan, Vietnam, and even in "enlightened" Europe, including Germany! And they fired for a long time... from the "Middle Ages" to the 20th century! So... "wooden" does not mean backward, primitive, or bad! There were wooden cannons with an iron liner and covered with iron hoops, like the Nuremberg cannon... and there were "pure" wooden ones, covered with ropes, for example, bamboo! They were both made of two halves and "solidly drilled"! A variety of wooden cannons are bamboo cannons... they fired grapeshot and not far away, but still, if you consider that the enemy in the jungle was sometimes detected only at arm's length!

    Wet Granulation of Gunpowder: Origin and Development of the Technology
    Germany (where large gunpowder mills existed),
    Italy (Venetian Republic),
    France and England by the end of the 15th century.
    The most developed system is considered to be the technology developed in the Hungarian city of Kassa (now Košice, Slovakia), as well as in German cities such as Nuremberg.

    Wet granulation technology of gunpowder
    Wet graining is a method in which black powder (composed of saltpeter, sulfur, and charcoal) is pressed while wet into grains of a specific size. This ensures uniform combustion and increased safety during storage and use.

    Stages of technology:
    1. Preparation of components
    Saltpeter, sulfur and charcoal are mixed in a certain proportion:
    Black powder = 75% saltpeter + 10% sulfur + 15% charcoal
    2. Grinding
    The components are thoroughly ground into a fine powder.
    This was done manually or using water mills.
    3. Adding water
    The mixture is moistened to the consistency of dough.
    Moistening ensured the plasticity of the powder mass, allowing it to maintain its shape when forming granules.
    4. Pressing
    The wet mass was forced through grates or molds with holes of the required diameter, producing long "sausages" or cylinders of gunpowder mass.
    5. Cutting and drying
    The resulting blanks were cut into pieces (grains) of the required size (about 5 mm).
    After this, the beans are dried in the shade or in dryers at low temperatures (up to 40–50 °C) to avoid ignition.
    6. Polishing and sifting
    The finished granules were polished and sieved into fractions.
    Different pellet sizes were used for different purposes:
    Large ones are for guns,
    Medium ones - for muskets,
    Small ones are for arquebuses.
    Why is wet graining better?
    Characteristics Powder gunpowder Grain gunpowder
    Burn rate Very high Controlled
    Pressure Unstable Uniform
    Security Low High
    Storage: Tends to cake; retains its properties for a long time
    Transportation Easily loses properties Resistant to shaking

    Examples of production in the 15th century
    The Venetian Gunpowder Factory (Arsenale di Venezia) was one of the first to introduce standardized graining.
    The French royal gunpowder manufactory in La Fère-en-Vexin (early 16th century) produced gunpowder using improved technology.
    In Germany, there were private workshops that supplied gunpowder for the army and trade.

      Before producing granulated gunpowder, they used an "intermediate" product... gunpowder in the form of "cakes," "lumps," or, in short, large "granules" or "pellets." This product was obtained by moistening the powder pulp and then grinding it. Apparently, they didn't immediately think of "granulating" it, or they didn't have the necessary equipment at hand! This "lumpy" gunpowder was suitable for artillery, but not for arquebuses! They had to find a way around it: they ground the "cake" gunpowder into "pulp" for rifles on the march! But this had to be done; the powder pulp quickly lost its properties over time!

          But we can pick up some examples.
          Some quotations from the book "De re metallica" by Georg Agricola (1556), concerning the production of gunpowder, from Chapter XII, which is devoted to the production of gunpowder and saltpeter.

          Original (Latin):
          "Pulvis tormentarius sic conficitur: accipiuntur partes tres salis petrosi, pars una sulphuris, & pars una carbo lignarius; quae omnia contunduntur in mortario ferreo usque ad impalpabilitatem..."
          Translation:
          "Gunpowder for guns is prepared as follows: take three parts of saltpeter, one part of sulfur and one part of charcoal; all this is ground in an iron mortar to a fine powder..."

          Original:
          "Deinde admiscetur aqua paulatim, donec massa coherere incipiat; postea exprimitur per foramina, ut granula efficiantur..."
          Translation:
          "Then water is added little by little until the mass begins to bind; after this it is pressed through holes to form grains..."

          Original:
          "Granula sic facta exponuntur ad solem vel ignem lentum, ut siccari possint; diligentissime vero cavendum est ne ignis appropinquet nimis, alioqui inflammabitur pulvis."
          Translation:
          "The grains thus obtained are exposed to the sun or to a gentle fire to dry; however, extreme care must be taken that the fire does not come too close, otherwise the gunpowder may ignite."

          Original:
          "Postquam siccata sunt granula, iterum comminuuntur & per cribrum trajiciuntur, ut ea reddantur aequalia & polita."
          Translation:
          "When the grains are dry, they are ground again and sifted through a sieve to make them uniform and smooth."

          Original:
          "Hoc modo optimus pulvis tormentarius conficitur, qui maximam vim habet si recte paratus fuerit."
          Translation:
          "This is how the best gunpowder is obtained for guns, which has great power if it is properly prepared."

          The device through which the gunpowder mass was forced to form grains was called a powder graining mold or a perforated plate press. Historical sources sometimes describe it as a "scraper with holes" (pressa cum foraminibus) or simply an ancient granulator.

          It was a simple mechanism consisting of:
          1. Wooden or metal body,
          2. A piston or press that was manually moved downwards,
          3. Perforated plate (metal or thick leather with many holes),
          4. Tray for collecting formed grains.


          1. Wet gunpowder mass (saltpeter, sulfur, coal) was placed in the container from above.
          2. The worker pressed on the piston, which pushed the mass through the holes.
          3. The result was cylindrical grains, which were then dried and polished.

          In Latin, the following terms were used in the description:
          * Machina perforans — perforating machine,
          * Torus cum foraminibus — a disk with holes,
          * Pressa pulveraria - gunpowder press.

            Gunpowder deserves its own article, and more than one! Black powder is a general term, while black powder is just a variety of black powder! Simply by varying the pyrolysis of wood, "brown," "red," and "chocolate" gunpowder were produced! And that's just part of the gunpowder "assortment"! Gunpowder differed in the ratio of its ingredients and in the size (shape) of its grains (granules)! Charcoal could sometimes be replaced with finely ground brown coal or fine dry sawdust (like the wood "dust" used to make MDF), or sugar!

              Well, yes, there are a lot of materials and studies on this topic.
              Here, for example, is the composition of gunpowder depending on the time of production (annotation). People are persistently researching all aspects.
              Medieval gunpowder formulations made from potassium nitrate (KNO3), charcoal (C), and sulfur (S8) were calorimetrically analyzed to determine the heat of combustion and ignition propagation velocity. Various sample preparation methods and several additional ingredients were also tested to determine their effect on thermodynamic performance. The gunpowder formulations were prepared and used in a replica cannon that was manufactured and operated according to medieval records. Overall, between 1338 and 1400, the KNO3 content increased and the heat of combustion decreased, while between 1400 and 1460, the KNO3 content decreased and the heat of combustion increased. However, since KNO3 was commonly detected in calorimetric materials after bomb explosions and in cannon discharge residues, it was not the limiting reagent. The highest pre-ignition and ignition propagation energies were achieved with a KNO3:S8 ratio of 3:1, as determined by DSC, and the highest heats of combustion were measured for recipes with a KNO3:C ratio of 1:1, as determined by bomb calorimetry.

        Glad I liked it.
        It's not interesting to write platitudes that are well known to everyone. I was looking for pictures of gunpowder mills.
        One could say that this image of such a machine is attributed to a famous 18th-century French encyclopedia, compiled, of course, by the great French encyclopedists. The original caption is valuable, allowing one to accurately identify it as a gunpowder mill.
        And another illustration, off topic, of course. However, the design for moving the boat to the canal bank is interesting. A mill is visible, but not a gunpowder one; perhaps it's a windmill that pumps water out of lowlands in Holland.

    They tell of a Swiss artilleryman named Bartolomeo Solari, who, in love with the beautiful Assunta, fired upon the Filarete Tower of the Castello Sforza in Milan in 1521, destroying it. The story and legend are much longer and more complex than I've described.

      According to "legend," Bartolomeo Solari, betrayed by the French who insulted his fiancée during the celebrations, used a medieval bombard to destroy the tower, killing hundreds of Frenchmen. The official version is that the tower, which served as a military depot and stored gunpowder, exploded after a lightning strike, and that is where the collapse and death of the French soldiers occurred.

    3. "EARTH CANNONS" There were some like that! I told you, "necessity is the mother of invention"! If there was no artillery, but you wanted to fire, you used improvised means... "holes" in the ground! No holes? Well, maybe dig! What else is a soldier to do when there's a lull? Dig! From the fence until lunch! So they dug in the earth, and sometimes in rocky ground... mmm: holes? holes? Well, and after "lunch", they poured gunpowder in there, rolled in whatever they had: a cannonball so a cannonball, a rock so a rock, (!)... or poured in rifle bullets, crushed stone! Cheap and cheerful!

      Earth camouflage! It's a shame they forgot to use it on the Borodino field. It was the perfect spot for these "firing mines."
