Battle of Cowpens

Durant Asmore provides a description of the Battle of Cowpens.
The Battle of Cowpens was a military engagement during the American Revolutionary War fought on January 17, 1781, near the town of Cowpens, South Carolina. American Patriot forces, estimated at 2,000 militia and regulars under Brigadier General Daniel Morgan faced 1,000 British troops under Lieutenant Colonel Banastre Tarleton.
The American victory was the worst loss suffered by British units since General John Burgoyne surrendered to General Horatio Gates at Saratoga in 1777. The British campaigned southward because of higher British support, or toryism, in the south, however pro-independence enthusiasm surged when news of the battle spread. Tactically, Cowpens demonstrated that American patriot militia, when properly led, could inflict heavy casualties on Britain's best-trained troops.
The double envelopment was a military tactic used by General Daniel Morgan during the battle. The tactic involved simultaneously attacking both flanks of the British, causing them to break rank and surrender.
The South Carolina militia attacked Tarleton's left flank. Washington's cavalry charged Tarleton's right flank. The American forces surrounded the British, who were forced to lay down their arms.
The double envelopment is still taught at West Point today. The battle was a major factor in the British abandoning South Carolina.
