Cornwallis’s corps marched to Princeton, which the Americans quitted the same day. The next day the corps marched in two divisions; the first advanced to Trenton, and reached the Delaware, just as the rear guard of general Washington’s army, under colonel Henly, gained the opposite shore, about twelve o’clock at night. Lord Cornwallis, who halted with the rear division within six miles of Trenton, intended crossing a body very early the next morning, near two miles below Corriel’s ferry; and got the troops in readiness, and the artillery prepared to cover the landing; for at that place it was only eight and twenty rod to a spit of sand on the Pennsylvania side, on which a sufficient number were to have landed, and then to have marched up to Corriel’s ferry, and to have taken the boats that had been collected there by the Americans, and left under a guard of only about ten men; with them it was meant to carry over the main body. In the vicinity of this place, a large sunken Durham boat (which came down three days before, laden with flour, and which could carry 100 men) lay concealed under a bank. This had been discovered and taken away by Mr. Mersereau, so that the British were disappointed in their expectation of finding it. They hailed one Thomson, a quaker, who lived on the other side of the Delaware, and enquired what was become of the boat, and were answered it was carried off. They continued reconnoitring up and down the river till ten o’clock, but finding no boats, returned to Pennytown. Men had been employed in time for taking off all the boats from the Jersey side of the Delaware; but Mr. Mersereau’s attention would not admit of his confiding wholly in their care and prudence. He therefore went up the river to examine whether all the boats were really carried off or destroyed; upon discovering the above sunken one, which had escaped the observation of the men, and enquiring of a person in the neighborhood concerning her, he was told that she was an old one, and good for nothing; but not relying upon the information, he found her to be new, had the water baled out, and sent her off.[31] The importance of this affair to the Americans, prevents the relation of it from being trifling. Had lord Cornwallis crossed into Pennsylvania as he proposed, the consequence would probably have been fatal to the Americans. Gen. Washington when he crossed, had about 2200 men; but the time of their service expiring, they left him in such a manner, that the second day after crossing he had but seventeen hundred.
