Fort Lernoult was abandoned by the British in 1796 as a condition of the Jay Treaty. The next day, U.S. Colonel Jean François Hamtramck occupied the fort and began making improvements. The U.S. would officially rename it to Fort Detroit. The British would re-capture Fort Detroit in August 1812, but abandon it again one year later as American forces advanced towards it. The British also abandoned Fort Miami, which the U.S. occupied until 1799. Like Fort Detroit, the British re-occupied Fort Miami during the War of 1812. It was abandoned in 1814 and eventually demolished.
