When the American Revolutionary War began, Egushawa was living in a village at the mouth of the Maumee River, the location of the present-day Toledo, Ohio. In April 1777, he traveled with British officials to Vincennes to help forge an alliance with some of the Wabash tribes. Egushawa saw much action in the war. He accompanied St. Leger's expedition in upstate New York, taking part in the bloody Battle of Oriskany on 6 August 1777. In 1778, he was the main chief with Hamilton's expedition to recapture Vincennes after it had been taken by Colonel George Rogers Clark of Virginia. In the 1783 peace treaty which ended the Revolutionary War, the British ceded the land of their Native American allies to the United States. In 1794, Egushawa was seriously wounded in the American Indian defeat at the Battle of Fallen Timbers in the future Ohio, north of the Maumee River. He signed the Treaty of Greenville on August 3, 1795, ceding much of southeastern Michigan but preserving some of northwest Ohio for Odawa use. He died near Detroit shortly thereafter, probably leaving no descendants.
