The British attempt to regain control of its rebellious colonies in the American Revolutionary War through the "southern strategy" of gaining control over the southern colonies and moving north began in late 1779 with the capture of Savannah, Georgia. By early 1781, Georgia and South Carolina were nominally under British control, two Continental Armies had been captured or routed, and General Lord Cornwallis was chasing a third, under the command of General Nathanael Greene, out of North Carolina. Greene, with a smaller and more mobile army, had risked division of his forces at one point, and was rewarded with Daniel Morgan's victory over Cornwallis' main cavalry force, led by Lieutenant Colonel Banastre Tarleton, at the Battle of Cowpens in January 1781.
