British & French Infantry Regiment, circa 1760

The establishment strength of a regular flank (grenadier or light infantry) company was 48 men; that of a fusilier [line) company was 42 - 44 men. Obviously, these figures were rarely acheived.

The British infantry regiment by 1759 was in a time of some transition

The British army, through its experience with light troops and rangers gained in America, was beginning to add a flank company of light infantry to each regiment in addition to the flank company of grenadiers already a part of regimental organization. Also, some of the British regiments were now coming to have several battalions (by the time of the American Revolution the number would be standardized at 3), whereas heretofore each regiment had consisted of but a single battalion in both the British and French armies. The 60th is the only British regiment at Quebec known to have had more than one battalion at this time -- no wholly authoritative source seems to exist to indicate how far this reorganization had gone by 1759. The question of the flank companies is rather academic, since these were grouped into separate grenadier and light infantry battalions, as was 18th Century custom, and did not ordinarily remain with their respective regiments during the campaign season.

The Louisbourg Grenadiers were formed from the grenadier companies of the 22nd, 40th and 45th regiments, none of which was present at Quebec.
