The artillery consisted of 120 soldiers and 16 guns. Since St. Clair's campaign had been slowed by their artillery, Wayne insisted that heavy canons be left at Fort Washington. Instead, he ordered 2.75 and 2.85 caliber howitzers that could be carried on horseback with special saddles. These guns could fire an iron ball, an explosive shell, or grapeshot against infantry at short range. Gun crews were trained to fire every 15 seconds. In addition, the Legion recovered artillery lost at St. Clair's defeat, and used these guns at Fort Recovery.
