With the main British infantry surrender and during Tarleton's retreat, Washington was in close pursuit and found himself somewhat isolated. He was attacked by the British commander and two of his men. Tarleton was stopped by Washington himself, who attacked him with his sword, calling out, "Where is now the boasting Tarleton?" A cornet of the 17th, Thomas Patterson, rode up to strike Washington but was shot by Washington's orderly trumpeter. Washington survived this assault and in the process wounded Tarleton's right hand with a sabre blow, while Tarleton creased Washington's knee with a pistol shot that also wounded his horse. Washington pursued Tarleton for sixteen miles, but gave up the chase when he came to the plantation of Adam Goudylock near Thicketty Creek. To escape capture by Washington, Tarleton had forced Goudylock to serve as an escape guide. For his valor at Cowpens, Washington received a silver medal awarded by the Continental Congress executed under the direction of Thomas Jefferson. The unique silver medal was designed by French artists Du Pre and De Vivier. (A British version of this duel can be found under Chapter 33 Year 1781.)
