Fort Dearborn on August 9, Hull ordered Heald to destroy all the arms and ammunition and give the remaining goods to friendly Indians in the hope of attaining an escort to Fort Wayne. Hull also sent a copy of these orders to Fort Wayne with additional instructions to provide Heald with all the information, advice and assistance within their power. In the following days, the sub-Native American agent at Fort Wayne, Captain William Wells, who was the uncle of Heald's wife, Rebekah, assembled a group of about 30 Miami Native Americans. Wells, Corporal Walter K. Jordan, and the Miamis traveled to Fort Dearborn to provide an escort for the evacuees. Wells arrived at Fort Dearborn on August 12 or 13 (sources differ), and on August 14, Heald held a council with the Potawatomi leaders to inform them of his intention to evacuate the fort.

Wells led the group with some of the Miami escorts, while the rest of the Miamis were positioned at the rear. About south of Fort Dearborn, a band of Potawatomi warriors ambushed the garrison. Heald reported that, upon discovering that the Indians were preparing to ambush from behind a dune, the company marched to the top of the dune, fired off a round and charged at the Native Americans. This maneuver separated the cavalry from the wagons, allowing the overwhelming Native American force to charge into the gap, divide, and surround both groups. During the ensuing battle, some of the Native Americans charged at the wagon train that contained the women and children and the provisions. The wagons were defended by the
