He served with distinction in the battles of Stono Ferry and Eutaw Springs, but recurring bouts of poor health often forced him to play an administrative role, or to convalesce in North Carolina. Following a drastic reduction in the number of North Carolinians serving with the Continental Army, Sumner became a general in the state's militia but resigned in protest after the North Carolina Board of War awarded overall command of the militia to William Smallwood, a Continental Army general from Maryland.
