United States presidential election in which John Adams beat Jay Treaty opponent Thomas Jefferson. The United States also negotiated the Treaty of Greenville in 1795. Utilizing St. Clair's defeat and Fort Recovery as a reference point, the Greenville Treaty Line forced the northwest Native American tribes to cede southern and eastern Ohio and various tracts of land around forts and settlements in Illinois Country; to recognize the U.S. rather than Britain as the ruling power in the Old Northwest; and to surrender ten chiefs as hostages until all American prisoners were returned. The Miami also lost private control of the Kekionga portage, since the Northwest Ordinance passed by Congress guaranteed free use of important portages in the region. Aftermath Fort Lernoult and Fort Miami were abandoned by the British in 1796 as a condition of the Jay Treaty. After two decades of efforts to take Detroit, U.S. forces under Colonel Hamtramck occupied Fort Lernoult the next day. The U.S. renamed Fort Lernoult to Fort Detroit and abandoned Fort Miami in 1799. The British re-captured Fort Detroit and Fort Miami during the War of 1812. Fort Detroit was abandoned one year later as American forces advanced towards it, and Fort Miami was abandoned in 1814 and eventually demolished. Most of the western U.S. forts were also abandoned after 1796; Fort Washington, the last, was moved across the Ohio River to Kentucky in 1804 to make room for a growing settlement at Cincinnati; it became the Newport Barracks. General Wayne supervised the surrender of British posts in the Northwest Territory and personally selected the construction site of Fort Wayne in Kekionga to secure his Legion's victory. Wayne died during a return trip to Pennsylvania from a military post in Detroit on December 15, 1796, one year after the ratification of the Treaty of Greenville. Wayne's second in command, General Wilkinson, was named as the new commander of U.S. forces. It was later learned that Wilkinson had secretly tried to undermine Wayne throughout the campaign, writing negative letters to civilian leaders and anonymously to local newspapers. Wilkinson was also a Spanish agent at the time. It has been speculated but never proven that Wilkinson had Wayne assassinated. After the end of hostilities, large numbers of United States settlers migrated to the Northwest Territory. Many made unscrupulous land deals with the Native nations, forcing General Wilkinson to invalidate them in a 1796 proclamation. Five
