On August 21, 1754, is born as the fourth child of John Tarleton, the former lord mayor of Liverpool, and a money lender, merchant and slave trader.
After completing his education at Oxford, Tarleton became the most feared officer in the British army during the War for American Independence, memorialized in portraits by Sir Joshua Reynolds and Thomas Gainsborough, as well as on film in The Patriot (2000), starring Mel Gibson, as the basis for the character Colonel William Tavington. The treatment of Patriot prisoners by Tarleton and his Loyalist troops in the Southern Campaign led to the coining of a phrase that came to define British brutality during of the last years of the War for Independence: 鈥淭arleton鈥檚 Quarter.鈥
After the surrender of Charleston, South Carolina, on May 12, 1780, the 3rd Virginia, commanded by Colonel Abraham Buford, was virtually the only organized Patriot formation remaining in South Carolina; Colonel 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鈥檚 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 鈥淭arleton鈥檚 Quarter,鈥 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, as wavering Carolina civilians terrified of Tarleton and their Loyalist neighbors were now prepared to rally to the Patriot cause.
After the British surrender at Yorktown, Virginia, in 1781, Tarleton returned to Britain where he served in Parliament as a representative from Liverpool and argued for the preservation of the slave trade. He became Sir Banastre Tarleton, 1st Baronet, in 1815. He died in 1833.
