In 1804, long before Chicago was a big city, Fort Dearborn was built on the Chicago River where the Magnificent Mile now begins. On August 15, 1812, the fort was attacked by Potawatomi Indians who killed 86 of the soldiers and their families. This 1928 bas-relief sculpture by Henry Hering is on the south bridge house of the Michigan Avenue Bridge (also called the DuSable Bridge). It shows Ensign George Ronan, from the Army’s 1st infantry regiment, during the battle shortly before he was killed.
