He accompanied Cornwallis to Charleston where he was sometimes commandant.^[1] He was promoted to major general in 1793, Colonel of both the 93rd Foot (1793) (an earlier regiment than the Sutherland Highlanders raised in 1799) and the 39th Foot in 1794 and served in the war with France.

He was elected to Parliament in 1790 as the MP for Wigtown Burghs, sitting until 1796 and again in 1797 for Arundel, sitting until 1802.
