The battle lasted about two hours and Harrison sustained 188 casualties: 37 died in action, 25 were mortally wounded. Another 126 sustained less serious wounds. The Yellow Jackets suffered the highest casualties of the battle, with all but one officer killed. The number of Native American casualties is still the subject of debate, but it was certainly lower than that of the American forces. Historians estimate that as many as 50 were killed and about 70 to 80 were wounded. The warriors retreated to Prophetstown where, according to one chief's account, they confronted Tenskwatawa, accusing him of deceit because of the many deaths, which his spells were supposed to have prevented. He blamed his wife for desecrating his magic medicine and offered to cast a new spell; he insisted that the warriors launch a second attack, but they refused.
