This retreat has always been regarded as one of the most brilliant incidents in Washington's career, and it would certainly be hard to find a more striking example of vigilance. Had Washington allowed himself to be cooped up on Brooklyn Heights he would have been forced to surrender; and whatever was left of the war would have been a game played without queen, rook, or bishop. For this very reason it is hardly creditable to Howe that he should have let his adversary get away so easily. At daybreak, indeed, the Americans had been remarkably favoured by the sudden rise of a fog which covered the East river, but during the night the moon had shone brightly, and one can only wonder that the multitudinous plash of oars and the unavoidable murmur of ten thousand men embarking, with their heavy guns and stores, should not have attracted the attention of some wakeful sentinel, either on shore or on the fleet. A storming party of British, at the right moment, would at least have disturbed the proceedings. So rare a chance of ending the war at a blow was never again to be offered to the British commanders. Washington now stationed the bulk of his army along the line of the Harlem river, leaving a strong detachment in the city under Putnam; and presently, with the same extraordinary skill which he had just displayed in sending boats under the very eyes of the fleet, he withdrew Colonel Prescott and his troops from their exposed position on Governor's Island, which there was no longer any reason for holding.
