Where did the battle of Valley Forge start?

Valley Forge never was a battle it was the camp of Washington's troops. They left from this camp on Dec. 24th , 1776 to cross the Delaware River to take the Hessian troops while they were having great fun for Christmas. His men were so ragged that they left bloody footprints in the snow because their boots had rotted or they didn't have any. This was the first win for Washington and helped push the American cause forward.
