On March 15, 1781, Nathanael Greene gave ground at Guilford Courthouse in a calculated fighting retreat, letting Cornwallis hold the field while bleeding his army with heavy casualties.
It was a victory the British could not afford. So weakened that he abandoned the Carolinas, Cornwallis marched his depleted army into Virginia — and toward the trap at Yorktown.
