The day after the battle, the American wounded were loaded onto wagons and brought back to Vincennes. They arrived at Fort Harrison about six days later. They boarded boats for the return to Vincennes on the river, arriving on November 18, at which point the militia was released home. Harrison informed Eustis of a battle near the Tippecanoe River, giving extensive details. Eustis replied with a note demanding to know why Harrison had not taken adequate precautions in fortifying his camp. Harrison replied that he had considered the position strong enough without fortification.
