Canon de 4 de Vallière

The Vallière system allowed only for the production of 24, 12, 8 and 4 pound (livre) guns, mortars of 8-pouce and 12-pouce, and stone-throwing mortars of 15-pouce (A French inch is a pouce.). The 24-pounder was the largest caliber available to French artillery in this system. The cannon used core drilling of the bore of cannons founded in one piece of bronze, a method developed at that time by Jean Maritz, which allowed for much higher precision of the bore shape and surface, and therefore higher shooting efficiency.

Starting with the front part, the gun had a sight design at it extremity. The followed the name of the gun (here Le Pénétrant). Then, a Latin phrase "Ultima Ratio Regum", initially introduced by Louis XIV, and rather descriptive of the role of the gun: "The Last Argument of the King". Under that appears the name "Louis Charles de Bourbon, comte d'Eu, duc d'Aumale", the Grand Maître de l'artillerie de France (Grand Master of the Artillery of France), followed by a royal emblem. In the middle of the cannon are trunnions, used to position the gun in place and elevate or depress it. On top of the trunnions are dolphin-shaped ornaments, which are used in lifting the gun.

The back part consists in, sometimes, an inscription showing the weight of the cannonball (for example a "4" for a 4-pounder), followed by a Latin inscription "Nec pluribus impar", meaning that the King is "Not unequal to many (suns)". This is followed by the royal crest of the Bourbon dynasty. At the bottom of the gun, the location and date of manufacture are inscribed, and finally the name and title of the founder (in the example "Fondu par J. Gor, Commissaire des Fontes"). The breech is decorated with an animal face showing the rating of the gun ("Face in a sunburst" for a 4-pounder).

Numerous de Valliere guns were used in the American War of Independence, especially the smaller 4-pdr field guns. The guns were shipped from France, and the field carriages provided for in the US. These guns played an important role in such battles as the Battle of Saratoga, or the Siege of Yorktown.
