Volunteers will also be treated to a 30 minute talk to hear the fascinating story of the Ten Crucial Days, December 25, 1776 to January 3, 1777, culminating with the battle on the Stony Brook Quaker Settlement farms of William Clarke, and his brother, Thomas Clarke. Learn how Washington and his outnumbered and untested troops with their backs against the Delaware River, fought a fierce battle in Trenton, then stealing away overnight, outflanked a the superior British Army, marched through frozen windswept farm land then fought again the next morning.  Hear how the the troops approached the field of battle and moment by moment managed to turn imminent defeat into a stunning victory that launched a nation.
