The Canon de 12 Gribeauval or 12-pounder was a French cannon and part of the system developed by Jean Baptiste Vaquette de Gribeauval. There were 1.079 English pounds in the Old French pound, making the weight of shot nearly 13 English pounds. The 12-pounder was the heaviest cannon in the French field artillery; the others were the light Canon de 4 Gribeauval and the medium Canon de 8 Gribeauval. Superseding the previous Vallière system, the Gribeauval system was adopted in 1765 and its guns were first used during the American Revolutionary War. The greatest use of Gribeauval guns came during the French Revolutionary Wars and the Napoleonic Wars. During the latter wars, the 12-pounder was often employed in corps artillery reserves. Because of their physical and psychological effect, Emperor Napoleon increased the number of 12-pounders in his artillery and fondly called the cannons his belles filles. Gribeauval cannons fired canister shot for close-range work and round shot at more distant targets. In 1803 the Year XI system was introduced, but it only partly replaced the Gribeauval system which was not completely replaced until the Valée system was set up in 1829.

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 was 1.07916 English pounds, making the weight of shot about 8.633 English pounds. 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. Emperor Napoleon began to phase out the 8-pounder by increasing the proportion of 12-pounders in his artillery. The emperor began switching calibers to the handier 6-pounder piece, utilizing captured guns as well as newly designed French cannons. The Year XI system began in 1803, but it only partly replaced the Gribeauval system which was not entirely suppressed until the Valée system was introduced in 1829.
The Canon de 8 Gribeauval, was the intermediate size between the Canon de 12 Gribeauval (left) and the Canon de 4 Gribeauval (right).

Napoleon Bonaparte's cannons put down an October 1795 attempted coup in Paris. The two cannons in the sketch are almost wheel to wheel; the minimum gap between guns was normally 10 meters.
