Reenactors took to the Delaware River on Christmas for the 67th year to recreate George Washington and his troops' daring attack on Christmas Day in 1776.

On that day, General George Washington led troops across the Delaware River to a surprise and successful attack against the Hessians – the German troops hired by the British to help fight during the American Revolution.

The Christmas crossing changed the course of history and boosted morale for the troops.

The ceremony started at 1 p.m. at Washington Crossing Historic Park in Bucks County and the troops crossed the river at around 1:30 p.m.

Organizers say the calm weather helped because in years past the event has been cancelled because the water was too low or too high or it was too windy or the water was frozen. 

In the Battle of Trenton, 22 Hessians were killed and more than 900 were captured. Two Americans froze to death.
