Following the American Revolutionary War, tensions remained high between the United States and Great Britain. When France declared war against Great Britain in 1793, the U.S. tried to remain neutral while continuing commerce with both, even as Great Britain supplied American Indians who were at war with the U.S. The Jay Treaty with Great Britain and the Treaty of Green Ville with the American Indians calmed conditions in 1795, but war between Great Britain and France resumed in 1803, and embargoes, British blockades of U.S. ports, impressment, and British support for American Indians opposing westward expansion led to the declaration of the War of 1812. After the August 4, 1794, Battle of Fallen Timbers, General Anthony Wayne sought alternatives to moving men and supplies overland through the Great Black Swamp, a mosquito-infested, densely forested swamp covering 1,500 square miles of what is now northwest Ohio and flooded most of the year. He turned instead to the rivers of northwest Ohio, which could carry the heavy watercraft needed to transport troops and supplies. Strategic land parcels were acquired at the head of navigable waters on the St. Marys River near Girty's town and along the Auglaize River at the head of navigation, where Fort Amanda would be established. These locations became important military supply depots for moving men and material, and by using the waterways Wayne reduced the distance between Loramie's Store and the Great Miami River from over 70 miles to 21, saving enormous cost. During the War of 1812, the Auglaize River and other tributaries of the Maumee River served first Wayne and later General William Henry Harrison as transportation routes, and Fort Amanda was one of several depots used to send supplies to Fort Meigs in support of the war.
