Christmas 1776 wasn't such a great time for two American generals. George Washington was wrapping a Christmas present for the Hessian garrison at Trenton, New Jersey. He was going to cross the Delaware and drop it down their metaphorical chimney like some kind of badass Santa Claus.
Second in command Charles Lee had checked into a tavern and sent his dogs and his army down the road a ways. With only a few guards and a dirty shirt, he was cooling his heels while waiting to decide to follow Washington's orders to join up with him.
In the meantime, British General Cornwallis, who was way more scared of Lee than Washington, sent Charles's old regiment of dragoons to find him and capture him.
Which they did. Merry Christmas, Charles...
