On this day in 1780, the treatment of Patriot prisoners by British Colonel Banastre Tarleton and his Loyalist troops leads to the coining of a phrase that comes to define British brutality for the rest of the War for Independence: "Tarleton's Quarter."
After the surrender of Charleston on May 12, the 3rd Virginia, commanded by Colonel Abraham Buford, was virtually the only organized Patriot formation remaining in South Carolina; British Colonel Banastre Tarleton had been given the mission to destroy any colonial resistance in the state. At Waxhaws on the North Carolina border, a cavalry charge by Tarleton's men broke the 350 remaining Patriots under Buford. Tarleton and his Tories proceeded to shoot at the Patriots after their surrender, a move that spawned the term "Tarleton's Quarter," which in the eyes of the Patriots meant a brutal death at the hands of a cowardly foe. The Continentals lost 113 killed and 203 captured in the Battle of Waxhaws; British losses totaled 19 men and 31 horses killed or wounded. Although they were routed, the loss became a propaganda victory for the Continentals: wavering Carolina civilians terrified of Tarleton and their Loyalist neighbors were now prepared to rally to the Patriot cause.
Under the leadership of Thomas Sumter, the Patriot militia quickly returned the terror in kind with their own brutal raids on Carolina loyalists. Carolinians went on to fight a bloody civil war in which they killed their own with far greater efficacy than any outsider sent to assist them.
