Mortier de 12 Gribeauval

The Mortier de 12 pouces Gribeauval (Gribeauval 12-inch mortar) was a French mortar and part of the Gribeauval system developed by Jean Baptiste Vaquette de Gribeauval. It was part of the siege artillery. The measurement of the mortar is expressed by the diameter of the ball, using the French ancient system of measurement, in which 1 pouce (1 inch) is worth 2.707 cm.

The Mortier de 12 pouces Gribeauval was used extensively during the wars following the French Revolution, as well as the Napoleonic wars. However, its first major operational use was even earlier, during the American Revolutionary War, in General Rochambeau's French expeditionary corps, from 1780 to late 1782, and especially at Yorktown in 1781.
