Taking the withdrawal of the first two lines as a full blown retreat, the British advanced headlong into the third and final line of disciplined Maryland and Delaware regulars which awaited them on the hill. The 71st Highlanders were ordered to flank the American right. John Eager Howard spotted the flanking movement and ordered the Virginia militiamen manning the American right to turn and face the Scots. However, in the noise of battle, Howard's order was misunderstood and the militiamen began to withdraw. It was now 7:45 am and the British had been fighting for nearly an hour. They were tired and disorganized, but they saw the Virginia militia on the rebels’ right withdrawing and believed the Americans were on the run. They charged, breaking formation and advancing in a chaotic mass. Morgan ordered a volley. Howard's "fleeing" militia suddenly stopped their withdrawal and made an about-face. The Virginians fired into the British at a range of no more than thirty yards, with massive effect, causing the confused British to lurch to a halt. John Eager Howard shouted, "Charge bayonets!"
