Stop in for a cup of coffee

Snow with a crust of ice like that always reminds of how that stopped an a raid to capture Gen. Washington at Morristown.
With the Hudson River, New York harbor and the Arthur Kill frozen by January 1780, attacks on outpost and other targets were already common. So its not too surprising some of Brits thought a deep raid could be pulled off. Maybe, it could have been, but the weather didn't cooperate. The horse's fetlocks were getting cut by the ice crust and they had to give it up.
