Battle of Cowpens, South Carolina - Jan 17, 1781 - HISTORY.com

At the Battle of Cowpens, Daniel Morgan was a Brigadier General. He had already resigned from the American Army due to medical reasons and dissatisfaction at being passed over in favor of lesser officers. General Gates convinced him to re-enter the Army after the American defeat at the Battle of Camden and he received his commission as a Brigadier.
Cowpens was a tactical masterpiece by "The Old Waggoner," who had fought under Braddock at the Battle of the Monongahela in 1755 (serving, coincidentally, as a teamster along with Daniel Boone) and as a rifle unit commander in the Revolution. He understood the use of regular troops and also his militia forces, and arranged them at Cowpens so as to get the best use out of them. He also got to know the character of Banastre Tarleton, the British Commander, who was famous for his disdain of American militia and hated for his lack of mercy. In the battle, Morgan coordinated his army's actions to carry out what has been described as one of the most perfect double envelopments in the history of modern warfare, thoroughly defeating the British and destroying Tarleton's forces. One defeated British unit was a battalion of the 71st Foot (Fraser's Highlanders - disbanded in 1783) - this was the only time Highlanders were defeated and fled during the war. Another regular British battalion at the battle was the 7th Foot (The Royal Fusiliers - now part of The Royal Regiment of Fusiliers in the British Army), most of which was captured and which suffered the ignomy of losing their Colours for the second time in the war (the first time being at the Siege of Fort Chambly in 1775 - those Colours are depicted in the background on the wall in the painting of the signing of the Declaration of Independence). The Battle of Cowpens had the effect of depriving Gen Cornwallis (the main British commander in the South) of his light infantry (capable of quick reaction) and the cavalry of Tarleton's Legion, which had a negative effect as he went into the Battle of Guilford Courthouse and his later advance into southern Virginia (ending at Yorktown).
After the Revolutionary War, BGen Morgan retired to his farm at Winchester VA. He was recalled to active service a few times (once for the Whiskey Rebellion in the 1790's) before his death and interment in Winchester. He was and remains a justly famous hero in early U.S. history.
