The Battle of Cowpens (January 17, 1781) was a decisive victory by Continental Army forces under Brigadier General Daniel Morgan in South Carolina over the British Army led by Colonel Banastre Tarleton, during the Southern campaign of the American Revolutionary War.
On October 14, 1780, George Washington chose Nathanael Greene to be commander of the Southern Department of the Continental forces.
Greene decided that his weak army was unable to meet the British in a standup fight he made the unconventional decision to divide his army.
By Christmas Day Morgan had reached the Pacolet River he was joined by 60 South Carolina militia led by the experienced partisan Andrew Pickens.
It was a decisive victory by a combined force of American Continental Army troops led by General George Washington and French Army troops
The battle boosted faltering American morale and revived French enthusiasm for the war, as well as undermining popular support for the conflict in Great Britain.
