Howe was now pushing forward all his available troops toward Princeton. Cornwallis hastened back to that place with the _elite_ of the army. While these heavy columns were gathering like a storm-cloud in his front Washington and his generals were haranguing their men, entreating them to stay even for a few weeks longer. Such were the shifts to which the commander-in-chief found himself reduced when in actual presence of this overwhelming force of the enemy. [Sidenote: Washington concentrates.] Through the efforts of their officers most of the New England troops reenlisted for six weeks--Stark's regiment almost to a man.[5] And these battalions constituted the real backbone of subsequent operations. Hearing that the enemy was at least ready to move forward, Cadwalader's and Mifflin's troops were called in to Trenton, and preparations made to receive the attack unflinchingly. This force being all assembled on the 1st of January, 1777, Washington posted it on the east side of the Assanpink, behind the bridge over which Rail's soldiers had made good their retreat on the day of the surprise, with some thirty guns planted in his front to defend the crossing. Washington and Rall had thus suddenly changed places. [Sidenote: His position, Jan. 2, 1777.] The American position was strong except on the right. It being higher ground the artillery commanded the town, the Assanpink was not fordable in front, the bridge was narrow, and the left secured by the Delaware. The weak spot, the right, rested in a wood which was strongly held, and capable of a good defence; but inasmuch as the Assanpink could be forded two or three miles higher up, a movement to the right and rear of the position was greatly to be feared. If successful it would necessarily cut off all retreat, as the Delaware was now impassable. On the 2d the enemy's advance came upon the American pickets posted outside of Trenton, driving them through the town much in the same manner as they had driven the Hessians. As soon as the enemy came within range, the American artillery drove them back under cover, firing being kept up until dark. Having thus developed the American position, Cornwallis, astonished at Washington's temerity in taking it, felt sure of "bagging the fox," as he styled it, in the morning.
