When he arrived at the fort on August 2nd Henry Proctor believed that Harrison would return to relieve the men inside. Fearing this he did not intend to stay for a prolonged siege. Instead he ordered his 1,400 men to attack the Fort directly hoping to overwhelm the defenders inside. With a combination of close range rifle, musket and artillery fire the defenders of the fort were able to push back multiple assaults by Proctor. After suffering about 60 casualties Proctor called off the attack and retreated before Harrison could arrive and wipe him out.
