The Régiment de Guyenne was a French Army infantry regiment in the 18th century.
It is principally known for its role in the Seven Years' War, when it served in the North American theatre.
The regiment participated in many battles: that of Fort Oswego in August 1756 and that of William Henry in 1757.
The uniform of the regiment was a bit like that of the Régiment de la Reine: a white-grey coat with red reversed sleeves with three ornate buttons: red vest, white-grey pants; black shoes with metallic buckles.
However, contrary to La Reine, the tricorne was black felt with a gold galon.
