Perhaps his most noted achievement was the victory in 1781 at the Battle of Hobkirk's Hill, in which, in command of only a small force, he defeated by superior military skill and determination, a much larger body of Americans. Thinking (in error) that General Nathanael Greene had moved his artillery away, Rawdon attacked Greene's left wing. Rawdon quickly concentrated his entire force on the American left flank, using the military advantage of local superiority, which forced the American line to collapse and abandon the field in disorder.
