Throughout the American Revolution, Shawnee warriors conducted raids against American settlements in Kentucky. In the summer of 1780, George Rogers Clark, hoping to prevent further attacks, led 1,050 men against the Shawnee living in the Miami River Valley. Among Clark’s soldiers was frontiersman Daniel Boone. The Americans crossed the Ohio River at what is now modern-day Cincinnati. The army burned five Shawnee villages, including Old Chillicothe, along the Little Miami River. The Americans also burned Loramie’s Store, a British trading post, in what is now Shelby County, Ohio. The Shawnees generally fell back before Clark’s army, but a major encounter between the two sides occurred on August 8, 1780, near what is now Springfield, Ohio. Known as the Battle of Piqua, both sides suffered significant casualties. Clark’s attack, successful as far as it went, did not reduce the tensions between the Americans and the American Indians of the Ohio Country.
