William Howe, 5th Viscount Howe, KB, PC was a British Army officer who rose to become Commander-in-Chief of British land forces in the Colonies during the American War of Independence. Howe was one of three brothers who had distinguished military careers. In historiography of the American war he is usually referred to as Sir William Howe to distinguish him from his brother Richard, who was 4th Viscount Howe at that time.
