Washington decided to attack the troops at Trenton. His men fit for duty did not exceed five thousand, and of these nearly two thousand were militia. The troops under Rahl consisted of three battalions of Hessians, having with them six field-pieces, fifty chasseurs, and twenty dragoons,—twelve hundred in all. Circumstances favored the plan which Washington now adopted. Colonel Griffin, with two companies of Virginians and some militia, had driven a party of Hessians, who had penetrated as far south as Moorestown and Haddonfield, back to Mount Holly, where they had been reinforced by Donop, who was thus too far removed from Trenton to support Rahl in case of an emergency. The success of Griffin made the militia at Bristol anxious for service, and it was decided by Cadwalader and Reed, who was with him, to gratify them by supporting Griffin. To this Washington assented, and at the same time confided to Reed and Cadwalader his contemplated movement against Trenton. On the morning of the 23d he wrote to them asking if the plan had been carried out, and informed them that one hour before day on the morning of the 26th was the time he had fixed upon for attacking Rahl. "For heaven's sake", he wrote, "keep this to yourselves as the discovery of it may prove fatal to us. Our numbers, sorry I am to say, being less than I had any conception of; but necessity, dire necessity, will, nay must justify an attack. Prepare and concert with Griffin; attack as many of their posts as you possibly can with a prospect of success; the more we can attack at the same instant the more confusion we shall spread, and the greater good will result from it." Washington was informed that it was impracticable to act with Griffin; and Reed repaired to Philadelphia to urge Putnam to create a diversion by crossing the river at Cooper's Ferry. He found, however, that little could be expected from Putnam, and returned to Bristol on the 25th, where Cadwalader was preparing to carry out the part which Washington had assigned to him. It was the intention of Washington to cross the Delaware above Trenton with about one half of his command, and attack the enemy, while Ewing and Cadwalader should cross opposite Trenton and Bristol, and not only cut Rahl's line of retreat but prevent Donop from reinforcing him.
