The other parts of this brilliant enterprise were not, however, executed with the same success. General Irvine had been instructed to cross at Trenton ferry, and, by securing a bridge below the town, to cut off the enemy's march along the Bordentown road. Notwithstanding all his exertions, it was found that the ice had rendered the passage impracticable; and five hundred fugitives from the disastrous field of Trenton were thus enabled to escape by a speedy and well-timed retreat. General Cadwallader was to have crossed at Drink's ferry, and carried the post at Mount Holly; but the same impediment prevented this movement also, and he was compelled to return with a part of his infantry which had effected the passage. Deprived of this important and expected cöoperation, Washington had, nevertheless, achieved a most critical and important triumph; he returned to his former position, charged with the spoils and trophies of his foes; and from that moment, though reverses frequently dimmed the brilliancy of the prospect, hope never again deserted the cause of American independence. Having secured the Hessian prisoners on the Pennsylvania side of the Delaware, Washington rëcrossed the river two days after the action, and took possession of Trenton. Generals Mifflin and Cadwallader, who lay at Bordentown and Crosswix with three thousand six hundred militia, were ordered to march up in the night of the 1st of January, to join the commander-in-chief, whose whole effective force, including this accession, did not exceed five thousand men. The detachments of the British army, which had been distributed over New Jersey, now assembled at Princeton, and were joined by the army from Brunswick, under Lord Cornwallis. From this position, the enemy advanced towards Trenton in great force, on the morning of the 2d of January; and, after some slight skirmishing with troops detached to harass and delay their march, the van of their army reached Trenton about four in the afternoon. On their approach, General Washington retired across the Assumpinck, a rivulet that runs through the town; and by some field-pieces, posted on its opposite banks, compelled them, after attempting to cross in several places, to fall back out of the reach of his guns. The two armies, kindling their fires, retained their positions on opposite sides of the rivulet, and kept up a cannonade till night.
