Having joined the army in 1746, Howe saw extensive service in the War of the Austrian Succession and Seven Years' War. He became known for his role in the capture of Quebec in 1759 when he led a British force to capture the cliffs at Anse-au-Foulon, allowing James Wolfe to land his army and engage the French in the Battle of the Plains of Abraham. Howe also participated in the campaigns to take Louisbourg, Belle Île and Havana. He was appointed Lieutenant-Governor of the Isle of Wight, a post he held until 1795.
