In June 1792, Native Americans and Kentucky settlers met for a prisoner exchange at Vincennes. William Wells, who fought with the confederacy at St. Clair's defeat, came to claim his wife Sweet Breeze, the daughter of Little Turtle. At Vincennes he met CPT Samuel Wells, his brother who had fought with the United States at St. Clair's defeat. William returned to Kentucky with his brother. That September, a U.S. delegation led by Rufus Putnam and John Hamtramck, and with assistance William Wells, returned to Vincennes and negotiated a treaty with the tribes of the lower Wabash River. The treaty and the Wabash tribes were celebrated in Philadelphia, and Henry Knox suggested that the confederacy had been weakened by 800 warriors. The U.S. senate would not consider the treaty for another 2 years, however, at which point it failed to ratify it.
