Much is made of Tarleton's Quarter, well here's some American Quarter. First at Kings Mountain.

Husbands was killed outright, Plummer badly wounded. Pattie himself was a conspicuous target, with his sword in his left hand, his bent-up right arm, and a checked duster-shirt protecting his uniform. A massive volley blasted him from the saddle. About a dozen balls shattered his body. His foot caught in the stirrup of his horse as he fell, and he was dragged along the ground. He died within minutes, in the arms of his friends. Jubilant Rebels stripped and urinated on his corpse, before his orderly Elias Powell and other companions were allowed to bathe and shroud him in a raw beef-hide.(¡Grande hazanas - Con muertos! to quote Goya in a later war...) He was buried in a shallow grave, beside poor Sal, from whose corpse a Rebel took a necklace of glass beads. Poll was taken prisoner, but released at Moravian Towns and returned to the army in Charlotte, where she apparently found a new protector.
"Don't kill any more! It's murder!" the Rebels' nominal commander, William Campbell protested as, with cries of "Give them Buford's play!" and "Tarleton's Quarter!", they ignored the Loyalists' white flags. Only with great difficulty did he prevent a wholesale massacre. Rebel casualties were 28 dead and 64 wounded, but 157 Loyalists were killed, and 163 so seriously hurt that they were abandoned on the mountain. Some were rescued by local Loyalists, and nursed back to health. Others were less fortunate: for weeks afterwards, turkey-buzzards, wolves and hogs fattened themselves on human carrion.
The rest - nearly 700 men, including walking wounded - were marched off as prisoners. Along the way, they were ill-used, even hacked with swords. Campbell had to order his officers to "restrain the disorderly manner of slaughtering and disturbing the prisoners". At Red Chimneys - plantation of Aaron Bickerstaff, a Loyalist Captain mortally wounded in the battle - nine militia officers were hanged from a tree after 'trial'. Another man was hanged for trying to escape. Cleveland beat up Uzal Johnson, the young New Jersey doctor, "for attempting to dress a man whom they had cut on the march", his friend Lieutenant Anthony Allaire (American Volunteers), wrote.
Tarleton and the Legion arrived 3 days too late, and learned the worst. Ban later wrote in his Campaigns: "the death of the gallant Ferguson threw his whole corps into total confusion... The mountaineers, it is reported, used every insult and indignity, after the action, towards the dead body of Major Ferguson, and exercised horrid cruelties on the prisoners that fell into their possession." (Yeah they took turns urinating on the man who had spared Washington's life.)

Henry "Light-Horse Harry" Lee
(1756 - 1818)

By Charles Willson Peale
Of the rebel cavalry officers, Harry Lee was most directly Banastre Tarleton's opposite number. Like Tarleton, Harry was an ambitious young officer, headlong and dashing on the field. If not for the outbreak of the war, he would have also been Banastre's school fellow. After his graduation from the College of New Jersey (now Princeton) in 1773, he was preparing to head off for the Middle Temple at roughly the same time Tarleton arrived there. But before he could sail, the colonial troubles flared towards open rebellion, and he found himself raising a troop of light cavalry instead of becoming a lawyer.

By 1778, he was in action, though his early career had its ups and downs. He received acclaim for several actions, but at one point he also faced a courtmartial on a long list of charges including reckless endangerment of his troops. Obviously, Harry was born to be a lawyer even if he missed his chance to study in England. He defended himself so well at his courtmartial that he was not only acquitted, he ended up with a Congressional medal.

Tarleton and Lee first butted heads on January 20, 1778, near Valley Forge. A British party commanded by Sir William Erskine, which included Captain Tarleton, attacked Lee's men at the Spread Eagle Tavern. Hoping to repeat his capture of Charles Lee, Ban led the charge -- but this time with less success. Harry sent him on his way with a wounded horse, a jacket full of buckshot and the loss of a helmet.

Lee was promoted to lieutenant colonel in late 1780, and shortly thereafter took "Lee's Partizan Corps" south to join Nathanael Greene's army.

He and Banastre met again frequently in 1781, as their units skirmishing around the edges of Greene's and Cornwallis's armies. It was during this period, on February 21, that Lee's men encountered a force of 600 Tories under the command of Colonel John Pyle (or Pile). Lee's Legion wore green uniforms that were extremely similar to those of Tarleton's British Legion, and the British Legion encampment was only a mile away. When green-coated dragoons rode into their midst, it was natural for the Tories to assume they were Tarleton's men. When they had Pyle's column essentially surrounded, Lee's Legion opened their attack, killing 90 Tories and wounding 150 more. Comments Bass, "The quality of Lee's mercy here was far worse than Tarleton's at the Waxhaws."
