[1] The 14th century saw considerable development of the new weapons in France and in Western Europe in general, especially with the outbreak of the Hundred Years' War (1337–1453).
[1] During the 1375 siege of Saint-Sauveur-le-Vicomte, French troops successfully breached the walls of the fortress with guns weighing over 1 ton, and firing 50 kg stone balls.
[1] Such bombards were often made by welding bars of wrought iron together and holding them inside circular bracelets, a process known as "à tonoille", similar to that involving the manufacture of wine barrels (tonneaux).
[1] The first Western image of a battle with cannon goes back to the Siege of Orléans in 1429, in which both the English and the French side are depicted with firearms.
[3] French artillery was used with great efficiency at the 1453 Battle of Castillon, in which grouped and entrenched cannons decimated the English army, killing the commander John Talbot.
[3] Artillery also started to affect military architecture, leading to the development of lower, thicker walls in order to better resist the effect of cannonballs.
