It was actually President Abraham Lincoln who helped designate Thanksgiving as the federal holiday we know and celebrate it today.
6. Crossing of the Delaware
General Washington and his Continental Army famously crossed the Delaware River on the cold night of December 25, 1776, a risky offensive maneuver which ultimately changed the course of the Revolutionary War.
An annual re-enactment occurs each December at the site. Thousands gather on the banks of the Delaware River to watch a recreation of George Washington’s daring 1776 Christmas night river crossing. During the event, hundreds of reenactors in Continental military dress listen to an inspiring speech by General Washington and then row across the river in replica Durham boats.
