Peteusha was a prominent Shawnee leader. His name has been spelled in a variety of ways, including Peteasua, Pataso, Petazo, Patasua, and Ptasua. He first appears in historical records at the time of Dunmore's War in 1774. Peteusha was among Cornstalk's war chiefs, as were Blue Jacket and Pukeshinwau. The Shawnees initially had the upper hand, but when colonial reinforcements arrived, the outnumbered Shawnees were pushed back. Near sundown, the Shawnees withdrew back across the Ohio River. Shawnee resistance to American occupation continued in the American Revolutionary War, which in the Ohio Country was fought between American settlers and Natives, with Natives getting support from their British allies in Detroit. By 1779 Peteusha was recognized as one of the leading Shawnee war chiefs. In 1782, Peteusha led Shawnees in the victory over Colonel William Crawford's army during the Crawford expedition. After the Revolutionary War, the United States claimed the lands north of the Ohio River by right of conquest. After the war, Peteusha eventually settled in Wapakoneta, the new Shawnee capital on the Auglaize River. There he supported Black Hoof's efforts to encourage Shawnees to adopt some American-style practices to better coexist with their white neighbors.
