27. Three days after his victory, Washington again crossed the Delaware. Here all the American detachments in the vicinity were ordered to assemble. To General Heath, stationed at Peekskill, Washington sent orders to move into New Jersey. The British fell back from their outposts and concentrated at Princeton. Cornwallis resumed command in person. So closed the year. Ten days previously, Howe only waited for the freezing of the Delaware before taking up his quarters in Philadelphia. Now it was a question whether he would be able to hold a single town in New Jersey. CHAPTER XXIV. OPERATIONS OF 1777. On the 1st of January, 1777, Washington's army at Trenton numbered about five thousand men. On the next day Cornwallis approached with greatly superior forces. During the afternoon there was severe skirmishing along the roads east of Trenton. During the night Washington called a council of war, and it was determined to leave the camp, pass the British left flank, and strike the enemy at Princeton. The baggage was removed to Burlington. The camp-fires were brightly kindled and kept burning through the night, while the army was in motion toward Princeton. Everything was done in silence. The morning light showed the British sentries a deserted camp. [Sidenote: =Battle of Princeton.=] 2. At sunrise Washington was entering Princeton. At the same time the British were marching out to reinforce Cornwallis. The Americans met them in the edge of the village, and the battle at once began. The British charged bayonets, and the militia gave way in confusion. General Mercer received a mortal wound. But the Pennsylvania regulars, led by the commander-in-chief, stood their ground. Washington rallied his men with the greatest bravery; and the British were routed, with a loss of four hundred and thirty men in killed, wounded, and missing. 3. On the night of the 22d of May, Colonel Meigs, of Connecticut, embarked two hundred men in whale-boats, crossed the sound, and attacked Sag Harbor. The British were overpowered; only four of them escaped; five or six were killed, and the remaining ninety were made prisoners. The stores were destroyed by the patriots, who, without the loss of a man, returned to Guilford. Colonel Meigs was rewarded by Congress with an elegant sword. 4. The patriot forces of the North were now concentrated on the Hudson; and a camp, under Arnold, was laid out on the Delaware. In the latter part of May, Washington broke up his winter-quarters and took an advantageous position only ten miles from the British camp. Howe crossed over from New York and threatened an attack upon the American lines. Finally, the British, on the 30th of June, crossed over to Staten Island. On the 10th of July, General Prescott, of the British army, was captured at a farm-house near Newport. This gave the Americans an officer of equal rank to exchange for General Lee. Congress in the mean time returned to Philadelphia. [Sidenote: =French Aid and Sympathy.=]
