Battle of Cowpens - Aftermath

Aftermath

Morgan's army took 712 prisoners, which included 200 wounded. Even worse for the British, the forces lost (especially the British Legion and the dragoons) constituted the cream of Cornwallis' army. Additionally, 110 British soldiers were killed in action. Tarleton suffered an 86 percent casualty rate, and his brigade had been all but wiped out as a fighting force. John Eager Howard quoted Maj. McArthur of the 71st Highlanders, now a prisoner of the Americans, as saying that "he was an officer before Tarleton was born; that the best troops in the service were put under 'that boy' to be sacrificed." An American prisoner later told that when Tarleton reached Cornwallis and reported the disaster, Cornwallis placed his sword tip on the ground and leaned on it until the blade snapped.

Historian Lawrence Babits has demonstrated that Morgan's official report of 73 casualties appears to have only included his Continental troops. From surviving records, he has been able to identify by name 128 Patriot soldiers who were either killed or wounded at Cowpens. He also presents an entry in the North Carolina State Records that shows 68 Continental and 80 Militia casualties. It would appear that both the number of Morgan's casualties and the total strength of his force were about double what he officially reported.

Tarleton's apparent recklessness in pushing his command so hard in pursuit of Morgan that they reached the battlefield in desperate need of rest and food may be explained by the fact that, up until Cowpens, every battle that he and his British Legion had fought in the South had been a relatively easy victory. He appears to have been so concerned with pursuing Morgan that he quite forgot that it was necessary for his men to be in a fit condition to fight a battle once they caught him.

Nevertheless, Daniel Morgan, known affectionately as "The Old Waggoner" to his men, had fought a masterly battle. His tactical decisions and personal leadership had allowed a force consisting mainly of militia to fight according to their strengths to win one of the most complete victories of the war.

Coming in the wake of the American debacle at Camden, Cowpens was a surprising victory and a turning point that changed the psychology of the entire war—"spiriting up the people", not only those of the backcountry Carolinas, but those in all the Southern states. As it was, the Americans were encouraged to fight further, and the Loyalists and British were demoralized. Furthermore, its strategic result—the destruction of an important part of the British army in the South—was incalculable toward ending the war. Along with the British defeat at the Battle of Kings Mountain, Cowpens was a decisive blow to Cornwallis, who might have defeated much of the remaining resistance in South Carolina had Tarleton won at Cowpens. Instead, the battle set in motion a series of events leading to the end of the war. Cornwallis abandoned his pacification efforts in South Carolina, stripped his army of its excess baggage, and pursued Greene's force into North Carolina. Skirmishes occurred at the Catawba River (February 1, 1781) and other fords. Yet, after a long chase Cornwallis met Greene at Guilford Court House, winning a pyrrhic victory that so damaged his army that he withdrew to Yorktown, Virginia, to rest and refit. Washington seized this opportunity to trap and defeat Cornwallis at the Battle of Yorktown, which caused the British to give up their efforts to defeat the Americans.

In the opinion of John Marshall, "Seldom has a battle, in which greater numbers were not engaged, been so important in its consequences as that of Cowpens." It gave General Nathanael Greene his chance to conduct a campaign of "dazzling shiftiness" that led Cornwallis by "an unbroken chain of consequences to the catastrophe at Yorktown which finally separated America from the British crown."
