Hull, William, 1753–1825, American general, b. Derby, Conn. He served brilliantly in the American Revolution and became in 1805 governor of the newly created Michigan Territory. As the War of 1812 began he asked Congress for a larger U.S. fleet on Lake Erie and reinforcements for Detroit. Hull, in command of Detroit, failed to make a planned attack on Canada and instead remained in Detroit until British forces under Sir Isaac Brock seized the fort on Aug. 16, 1812, capturing many supplies. Hull was court-martialed for cowardice and neglect of duty, and only his Revolutionary War record prevented his execution. Subsequent evidence has shown that Hull was not solely to blame for the disastrous campaign.
