The Canon de 8 Gribeauval or 8-pounder was a French cannon and part of the Gribeauval system developed by Jean Baptiste Vaquette de Gribeauval. The Old French pound (French: livre) was 1.07916 English pounds, making the weight of shot about 8.633 English pounds (or 8 lb 10 oz). The 8-pounder was the medium weight cannon of the French field artillery; the others were the light Canon de 4 Gribeauval and the heavy Canon de 12 Gribeauval. Replacing the older Vallière system, the Gribeauval system was introduced in 1765 and the guns were first employed during the American Revolutionary War. The most extensive use of Gribeauval guns was during the French Revolutionary Wars and the Napoleonic Wars. The 8-pounder could be found in divisional reserves, advanced guards or army artillery reserves. Em
