Battle of Fort Dearborn - Location of The Battle

Location of The Battle

Eye-witness accounts place the battle on the lake shore somewhere between 1 and 2 miles (1.6 and 3.2 km) south of Fort Dearborn. Heald's official report said the battle occurred 1+1⁄₂ miles (2.4 km) south of the fort, placing the battle at what is now the intersection of Roosevelt Road (previously known as, 12th Street) and Michigan Avenue. Juliette Kinzie, shortly before her death in 1870, stated that the battle had started by a large cottonwood tree, which at that time still stood on 18th Street between Prairie Avenue and the lake. The tree was supposed to have been the last remaining of a grove of trees that had been saplings at the time of the battle.

The tree was blown down in a storm on May 16, 1894 and a portion of its trunk was preserved at the Chicago Historical Society. Historian Harry A. Musham points out that the testimony relating to this tree is all second hand and came from people who settled in Chicago more than 20 years after the battle. Moreover, based on the diameter of the preserved section of trunk (about 3 feet (0.91 m)) he estimated the age of the tree at the time that it was blown over at no more than 80 years, and therefore asserts that it could not have been growing at the time of the battle. Nevertheless, the site at 18th Street and Prairie Avenue has become the location traditionally associated with the battle, and on the battle's 197th anniversary in 2009, the Chicago Park District, the Prairie District Neighborhood Alliance and other community partners dedicated "Battle of Fort Dearborn Park" near the site at 18th Street and Calumet Avenue.
