Even at the height of the Cherokee threat in the Spring and Summer of 1776, the Wataugans heeded a call to arms and dispatched a company of riflemen under Felix Walker to aide in the defense of Charleston in South Carolina. In August 1780, a small contingent led by Col. Isaac Shelby fought in the American Patriot victory at the Battle of Musgrove Mill near present-day Clinton, South Carolina. In late September 1780, the Overmountain Men—the frontier militia that crossed the Appalachian Mountains and defeated an army of British loyalists at the Battle of Kings Mountain—mustered at Sycamore Shoals, and included 240 Wataugans under the command of Cols. John Sevier and Isaac Shelby. After the battle, Sevier led a second punitive expedition against the Cherokee in which he destroyed the Chickamauga Cherokee villages near modern Chattanooga.
