Egushawa saw much action in the war. He accompanied St. Leger's expedition in upstate New York, taking part in the bloody Battle of Oriskany on 6 August 1777. In 1778, he was the main chief with Hamilton's expedition to recapture Vincennes after it had been taken by Colonel George Rogers Clark of Virginia. He admonished Piankeshaw chief Young Tobacco for working with the Virginians, which Hamilton understood to be a threat. Clark made a surprise return to Vincennes in 1779 and captured Hamilton, but Egushawa escaped. In 1780, his war band accompanied Captain Henry Bird's invasion of Kentucky, in which two American "stations" (fortified settlements) were captured.
