In 1760 he served at the reduction of Isle-aux-Noix and at the capture of Montreal, which completed the conquest of Canada. In 1764 he was appointed captain in the forty-sixth foot, with which corps he served two years on the frontiers of North America, one year at New York, and eight in Ireland.

In 1776, he was promoted to major in the fifty-fifth, but continued to perform the duty of first aide-de-camp to Sir William Howe, then commanding-in-chief in North America, and served at the reduction of Long Island, the capture of New York, and the battle of White Plains. He also accompanied the expedition to Pennsylvania in 1777, and served at the battles of Brandywine, and Germantown, and in November of that year he succeeded Colonel Meadows, who was removed to the fifth foot, in the lieutenant-colonelcy of the fifty-fifth, which corps he commanded in the retreat from Philadelphia to New York in 1778, and was at the battle of Freehold, under Lieutenant-General Sir Henry Clinton.
