Washington found no rest at Princeton. Cornwallis no sooner heard the cannonading near Princeton than he immediately comprehended Washington's ruse, and, alarmed for his magazines at New Brunswick, he hastened in that direction. Washington, aware of his approach, found it necessary to give up the attempt on New Brunswick. He therefore hastened across Millstone river, broke down the bridge behind him to stop pursuit, and posted himself on the high ground at Morristown, where there were very strong positions. Here he received additional troops, and entrenched himself. Cornwallis, not aware of the real weakness of Washington's army despite all its additions, again sat down quietly for the winter at New Brunswick. For six months the British army now lay still. Washington, however, lost no time in scouring all quarters of the Jerseys. He made himself master of the coast opposite Staten Island, and seized on Newark, Elizabeth Town, and Woodbridge. The inhabitants had been plundered by the Hessians and English, and now they were plundered again by their own countrymen for having received the English well. Washington exerted himself to suppress this rancorous conduct of the New England and Virginian troops, and issued a proclamation absolving the people of their oaths to the English, and promising them protection on their taking a new oath to Congress. The people of the Jerseys gladly accepted this offer.
