. "The Canon de 4 de Valli\u00E8re was a type of cannon designed by the French officer Florent-Jean de Valli\u00E8re ( 1667-1759), Director-General of the Battalions and Schools of the Artillery. The cannon was a result of the Royal Ordonnance of October 7, 1732, edicted to reorganize and standardize the King's artillery 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."@en .

The cannon was a result of the Royal Ordonnance of October 7, 1732, edicted to reorganize and standardize the King's artillery Whereas numerous formats and designs had been in place in the French army, De Valli\u00E8re standardized the French sizes in artillery pieces, by allowing only for the production of 24, 12, 8 and 4 pound guns, mortars of 13 and 9 inches, and stone-throwing mortars of 16 inches. The 24-pdr 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. As with other de Valliere guns, the 4-pdr was also highly decorated and contained numerous designs and inscriptions."@en .
