War of 1812: Potawatomi warriors ambushed a United States Army convoy after it had evacuated Fort Dearborn (site pictured), in present-day Chicago, and razed the fort.

The War of 1812 was fought by the United States and its allies against the United Kingdom and its allies in North America. It began when the United States declared war on Britain on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by the United States Congress on 17 February 1815.

The Potawatomi, also spelled Pottawatomi and Pottawatomie, are a Native American tribe of the Great Plains, upper Mississippi River, and western Great Lakes region. They traditionally speak the Potawatomi language, a member of the Algonquian family. They are additionally First Nations in Canada. The Potawatomi call themselves Neshnabé, a cognate of the word Anishinaabe. The Potawatomi are part of a long-term alliance, called the Council of Three Fires, with the Ojibwe and Odawa (Ottawa). In the Council of Three Fires, the Potawatomi are considered the "youngest brother". Their people are referred to in this context as Bodéwadmi, a name that means "keepers of the fire" and refers to the council fire of three peoples.

The Battle of Fort Dearborn was an engagement between United States troops and Potawatomi Native Americans that occurred on August 15, 1812, near Fort Dearborn in what is now Chicago, Illinois. The battle, which occurred during the War of 1812, followed the evacuation of the fort as ordered by the commander of the United States Army of the Northwest, William Hull. The battle lasted about 15 minutes and resulted in a complete victory for the Native Americans. After the battle, Fort Dearborn was burned down. Some of the soldiers and settlers who had been taken captive were later ransomed.

Fort Dearborn was a United States fort, first built in 1803 beside the Chicago River, in what is now Chicago, Illinois. It was constructed by U.S. troops under Captain John Whistler and named in honor of Henry Dearborn, then United States Secretary of War. The original fort was destroyed following the Battle of Fort Dearborn during the War of 1812, and a replacement Fort Dearborn was constructed on the same site in 1816 and decommissioned by 1837.
