On August 22, the Dakota repeated the attack plan used on the 20th: a volley of three shots from the north followed by a rush of warriors from the east, south, and west. The plan was disrupted when a mail carrier was spotted on the New Ulm road and warriors by the road killed him with three shots. Dakota on the south and west mistook those shots for the signal and launched a premature attack. Even so, the fighting was fierce. Tasina Wakanhdi, Lightning Blanket, recalled that during the day many small buildings were burned and attempts were made to burn the large ones with fire arrows. Warriors moved into the fort's stables and sutler's store, but those buildings were shelled and then burned. After several hours, the attack began to falter as the warriors were divided between fighting another battle and attacking New Ulm again for spoils.
