It was weary work retreating. But with masterly generalship, and untiring watchfulness, Washington avoided a battle, and slipped through the toils. As the pursued and pursuers neared Philadelphia something like panic laid hold of the city. All day long the rumble of wagons might be heard carrying women and children to places of safety. Congress was hurriedly removed to Baltimore; but hundreds of men seized their rifles and marched to join the army to fight for their country in its darkest hour. But already the worst was over. Washington's army was now well reinforced. He had the recruits from Philadelphia, he had Lee's army, and he also had two thousand men sent him by Schuyler from the north. So he resolved to make a bold bid for fortune. He resolved to do or die. He gave as the password, "Victory or death," and in the dark of Christmas night, 1771, he and his men crossed the Delaware River above the town of Trenton, where the British lay, together with a large company of the Hessian troops who had been hired to fight the Americans. The river was full of floating ice, which made the crossing dangerous and slow. But through the darkness the men toiled on, fending off the ice blocks as best they could as they steered their boats through the drifting mass. At length, after ten hours' labour, they reached the other side without the loss of one man. It was four o'clock when the troops started off on their seven-mile march to Trenton over the snowy ground, the icy wind driving the sleet and snow in their faces. But by eight o'clock they had reached Trenton. The British were utterly taken by surprise, and almost at once the Hessians surrendered. Having sent his prisoners, to the number of nearly a thousand, to the other side of the river, Washington took possession of the town. But he was not long allowed to remain there. For the British commander, Lord Cornwallis, marched to dislodge him with an army of eight thousand men. Washington let him come, and on the 2nd of January, Cornwallis encamped before Trenton, determined next morning to give battle. He was sure of victory, and in great spirits. "At last we have run down the old fox, and we will bag him in the morning," he said. But Washington was not to be so easily caught. The two armies were so near that the watchfires of the one could be plainly seen by the other. All night the American watchfires blazed, all night men could be heard working at the fortifications. But that was only a blind. In the darkness Washington and his army quietly slipped away to Princeton. There he fell upon the British reinforcements, who were marching to join Cornwallis at Trenton, and put them to flight.
