One of the first things that most school children are taught about American history is Washington’s crossing of the Deleware River. Since it happened in the dark of night the day after Christmas in 1776 it was a rather dramatic event. It was also an important victory for the fledgling American army who had suffered mostly defeats up till then.
If you are ever near Trenton New Jersey you should stop in at the Washington Crossing Historic Park and hear the full story. The museum there is full of artifacts. Nearby is also the Old Barracks Museum showing things about military life during that period. Both are well worth your time.
