The Obusier de 6 pouces Gribeauval or 6-inch howitzer was a French artillery piece and part of a system established by Jean Baptiste Vaquette de Gribeauval. The Old French inch was 1.066 English inches long so the weapon can accurately be described as a 6.4-inch howitzer.

The VII Corps of the Grande Armée was a French military unit that existed during the Napoleonic Wars. It was formed in 1805 and assigned to Marshal Pierre Augereau. From 1805 to 1807, Augereau led the VII Corps in the War of the Third Coalition and the War of the Fourth Coalition. It was disbanded after being nearly wiped out at the Battle of Eylau in February 1807 and its surviving troops were distributed to other corps.
