Townshend was given command of a brigade in Quebec under General James Wolfe; when the latter died on 13 September 1759, and his second-in-command (Robert Monckton) was wounded, Townshend took command of the British forces during Battle of the Plains of Abraham. He received Quebec City's surrender on 18 September 1759. However, he held General Wolfe in much contempt (drawing Wolfe in caricature he created Canada's first cartoon), and was harshly criticized upon his return to Great Britain for that reason (Wolfe was a popular hero throughout the country). Nevertheless, he became colonel of the 28th Regiment of Foot in October 1759, was promoted to major general on 6 March 1761 and fought at the Battle of Villinghausen in July 1761. In May 1762 he took command of a division of the Anglo-Portuguese army, with the local rank of lieutenant-general, to protect Portugal during the Spanish invasion of Portugal.
