Tarleton is described as “a twenty-six-year-old terrorist who dressed the part of a dandy in tight breeches and tall black boots and directed his men to slash and stab and spare no one.” James Patton, The Life of Andrew Jackson (New York: Mason Bros., 1869), 89.
Andrew Jackson Future president was working with his mother to saves the lives of the men left for dead from the Waxhaws Massacre.
When he was ordered to shine the boots of a British officer that was under Banister Tarleton's command and when he did not comply was slashed over the head by that British officer for having the temerity to refuse the demand to clean his boots.
Tarleton was reprimanded by Cornwallis for killing wounded soldiers, civilians, captured Soldiers (Calling them traitors, suppliers, supporter or spies) because from his own words did not want to fight the same men again.
It wasted his manpower taking prisoners to see them exchanged to fight them again.
