On the evening of September 20, 1777, near Paoli, General Charles Grey and nearly 5,000 British soldiers launched a surprise attack on a Patriot encampment, which became known as the Battle of Paoli. Having intercepted General Washington's orders to General Wayne regarding British rearguard actions, Grey directed his troops to assault the small regiment of Americans commanded by Anthony Wayne in an area near his residence. Not wanting to lose the element of surprise, Grey ordered his troops to remove the flint from their muskets and to use only bayonets or swords to launch a surprise sneak attack on the Americans under the cover of darkness.
