A second battalion of the Royal Roussillon served in Germany (1756–1762). In 1756, the 54th Infantry Regiment's uniform was white with blue facings, five gilded buttons for the linings and three buttons on each pocket. Its first battalion fought in Canada during the French and Indian War from 1756 to 1761, under the command of général Louis-Joseph de Saint-Veran, Marquis de Montcalm, with M. de Sennezergue as its colonel. The battalion arrived in New France in May 1756, and was originally posted to Montreal, with the exception of a detachment that was sent to Fort Carillon. It fought at the Battle of Fort William Henry. After that victory, the regiment took part in the 1758 Battle of Carillon. It then went to Quebec City to defend the city. At the Battle of the Plains of Abraham, it was broken and forced to flee by steady fire from the British 35th Foot, whose members are traditionally held to have picked up the 54th's plumes and placed them in their own headdress (the Roussillon Plume being formally incorporated into the badge of the 35th Foot in 1881).
