Fort Dearborn

On August 15, 1812, near what was then Fort Dearborn in Illinois Territory in the Chicago area, American soldiers, militia, and Miami native auxiliaries clashed with Potawatomi Native Americans in a fight sometimes known as the Fort Dearborn Massacre. This clash came about after William Hull, commanding the United States Army of the Northwest, gave the order to abandon the fort, and it formed part of the larger conflict of the War of 1812. Fighting stretched across roughly fifteen minutes and ended in a decisive win for the Potawatomi side. Once the engagement concluded, the fort itself was set ablaze. Certain captured soldiers and settlers eventually gained their freedom through ransom.

In the aftermath, as more settlers kept arriving in the region, federal officials grew certain that every Indian needed to be pushed out of the territory and away from areas where settlements existed. Fort Dearborn would not stand again until it was reconstructed in 1816.

Battle

War came to the United States and the British Empire on June 18, 1812, and within weeks, on July 17, the British had seized Fort Mackinac along the northern shore of Lake Michigan. Word of this loss reached General William Hull on July 29, prompting him to dispatch immediate orders for Heald to abandon Fort Dearborn on the lake's southern shore, since he doubted the post could be kept supplied any longer. Hull's letter reached Heald on August 9, directing him to destroy the fort's weapons and munitions while distributing whatever remained to friendly tribes, in hopes this would secure an escort to Fort Wayne. Hull also forwarded these same instructions to Fort Wayne, southeast across the lake, adding that the garrison there should offer Heald whatever guidance and aid it could muster.

In the days that followed, Captain William Wells, the sub-agent to the Native Americans stationed at Fort Wayne and uncle to Heald's wife Rebekah, gathered roughly thirty Miami warriors. Along with Corporal Walter K. Jordan, Wells and this Miami contingent set out for Fort Dearborn to guide the evacuation.

Accounts vary on whether Wells reached the fort on August 12 or the following day. What is clear is that on August 14, Heald convened a council with Potawatomi leaders to announce his plans to abandon the post. The natives came away believing Heald had promised to hand over firearms, ammunition, provisions, and whiskey, along with a substantial payment, in exchange for a Potawatomi escort to Fort Wayne. Instead, Heald had the surplus weapons, powder, and liquor destroyed, explaining that he feared what the Indians might do if such items fell into their hands. That same day, a Potawatomi chief named Black Partridge cautioned Heald that the tribe's younger men meant to strike and that his influence over them had run out.

The following morning, at nine o'clock on August 15, the garrison marched out toward Fort Wayne. Per Heald's own account, the column numbered 54 regular soldiers, 12 militiamen, nine women, and 18 children. Wells rode at the head alongside a portion of the Miami escort, with the remainder trailing at the back. Roughly a mile and a half south of the fort, Potawatomi warriors sprang an ambush. Heald later wrote that once his men spotted the Indians massing behind a dune, the company pushed to its summit, loosed a volley, and charged forward.

This move opened a gap between the mounted troops and the wagons, and the much larger native force poured through it, splitting into two and encircling both segments of the column. As fighting spread, warriors turned on the wagon train, which held the women, children, and supplies. Militia troops, together with Ensign George Ronan and the post's surgeon, Van Voorhis, tried to hold the wagons. All the officers and militiamen died there, along with two women and nearly all the children. Wells broke away from the fighting elsewhere and tried to reach the wagons, but he was cut down before he could help. Witnesses later said he battled several warriors before falling, and afterward some of the Indians cut out his heart and consumed it, believing it would grant them his bravery.

Within about fifteen minutes the fighting ended, and Heald withdrew with the surviving troops to higher ground on the prairie. There they surrendered and were marched off as captives to a native encampment near the fort. Heald's own tally of losses listed 26 regulars, the entire militia contingent of 12, two women, and twelve children dead, while 28 regulars, seven women, and six children survived as prisoners. Those who lived through the massacre later disagreed about the Miami escort's role, some insisting they had fought on the American side, others claiming they never engaged at all.

Historical perspective

Placed against the backdrop of the War of 1812 and the wider struggle between Britain and France that set it in motion, this clash was a modest and short-lived affair, yet its ripple effects on the territory proved substantial. One could argue that for the Native Americans involved, the outcome amounted to prevailing on the field while ultimately losing the broader struggle, since the US afterward carried out a policy aimed at pushing the tribes from the region. That policy culminated in the 1833 Treaty of Chicago, an era that closed in 1835 with the last great Native American war dance held in the young city. From that point forward, the Potawatomi and other tribes were pushed further to the west.
