the civilian leader of the small settlement that grew around the fort. In 1810, Kinzie and Whistler became embroiled in a dispute over Kinzie supplying alcohol to the Indians. In April, Whistler and other senior officers at the fort were removed; Whistler was replaced as commandant of the fort by Captain Nathan Heald. The Battle of Fort Dearborn During the War of 1812, General William Hull ordered the evacuation of Fort Dearborn in August 1814. Capt. Heald oversaw the evacuation, but on August 15 the evacuees were ambushed along the trail by about 500 Potawatomi Indians in the Battle of Fort Dearborn. The Potawatomi captured Heald and his wife, Rebekah, and ransomed them to the British. Of the 148 soldiers, women, and children who evacuated the fort, 86 were killed in the ambush. The Potawatomi burned the fort to the ground the next day. The second fort Following the war, a second Fort Dearborn was built (1816). This fort consisted of a double wall of wooden palisades, officer and enlisted barracks, a garden, and other buildings. The American forces garrisoned the fort until 1823, when peace with the Indians led the garrison to be deemed redundant. This temporary abandonment lasted until 1828, when it was re-garrisoned following the outbreak of war with the Winnebago Indians. In her 1856 memoir, Wau Bun, Juliette Kinzie described the fort as it appeared on her arrival in Chicago in 1831: The fort was closed briefly before the Black Hawk War of 1832 and by 1837, the fort was being used by the Superintendent of Harbor Works. In 1837, the fort and its reserve, including part of the land that became Grant Park, was deeded to the city by the Federal Government. In 1855, part of the fort was demolished so that the south bank of the Chicago River could be dredged, straightening the bend in the river and widening it at this point by about ; and in 1857, a fire destroyed nearly all the remaining buildings in the fort. The remaining blockhouse and few surviving outbuildings were destroyed in the Great Chicago Fire of 1871. Legacy and monuments The southern perimeter of Fort Dearborn was located at what is now the intersection of Wacker Drive and Michigan Avenue in the Loop community area of Chicago along the Magnificent Mile. Part of the fort outline is marked by plaques, and a line embedded in
