The 52nd began as a standard infantry line regiment in 1755, when Colonel Hedworth Lambton received papers to raise a new regiment, to be numbered as the 54th Foot. It was renumbered as the "52nd Regiment of Foot" in 1757, and was stationed in England and Ireland. (At the same time, the previous 52nd Foot was renamed the 50th Foot.) In 1765, the Regiment was posted to Canada. The 52nd was shipped to America from Canada, arriving in Boston, and fought in the battles of Lexington and Bunker Hill in 1775. Major-General William Howe led the main assault at Bunker Hill with Brigadier Robert Pigot leading the 52nd and 43rd Foot in support. This was the first occasion that the 52nd fought alongside the 43rd. They suffered heavy casualties at Bunker Hill, and in their grenadier company, only 8 men were left unwounded. In August, 1778, the men were drafted into other regiments and the officers returned to England. The regiment obtained new recruits and in 1782 the introduction of county titles for regiments resulted in the 52nd adding "Oxfordshire" to their name.
