Again the British slept on, unconscious of what was happening, and in the early morning an empty camp confronted them. But at the same time his Majesty's forces at Princeton were astonished to see well-formed bodies of troops swinging along the road toward their encampment on the hill about the college buildings. George's company had halted, and was waiting for the word. It was a very strange sight indeed, for the command was drawn up to the side of a little brook, just across an arched stone bridge. As the light broadened they could see coming down the road in front of them a line of red standing out brightly against the bare meadows and patches of snow. They did not seem to be afraid of the forces gathered below them in the meadow, for they did not even form a line of battle. Everything was quiet. A rabbit jumped from a thicket, darted out and bobbed across the field. Some snow-birds twittered in the leafless branches overhead; but soon was the stillness to be broken. "I declare, I don't think they see what they're about!" exclaimed a soldier. The fact was, the regiment of British soldiers had taken the Americans at first for Hessians. Soon, however, they were to be undeceived, for a volley from a company off to the right warned the officers, and the Redcoats spread out across the hill-side. A body of Americans at this moment came out of a hollow and met them face to face. It was a mutual surprise, and the fighting began at once. Some horsemen galloped back in the direction of Princeton, one and a half miles or so away. Re-enforcements of the enemy were hurried down the road on a run. The detachment with which George had been standing charged up to join the hand-to-hand fighting at the front. The battle had opened. Most of the Americans near the stone bridge were raw militia. They could not be made to fire in volleys, but each man apparently fought for himself. They had had little drilling, not having been in the affair at Trenton, and this was their first sight of blood. George saw that exhorting was of no avail. The men were full of fight, but they were not trained to listen. He sheathed his sword, and picked up a musket from the ground. The Redcoats, advancing in their well-dressed line, came steadily on. The ranks of the militia broke and retreated; only a few stood their ground. A man on horseback rode to the front. He stood up in his stirrups, shouted, and waved his sword about his head. "Mark ye him there on the gray horse--'tis General Mercer," a voice shouted, as the militia once more began to rally. "Stand firm! stand firm!" the officer was crying. Suddenly his steed reared, and the rider leaped up in the saddle, and, leaning across the big gray's neck, slid to the ground. The horse stumbled and fell immediately, and the General was seen almost alone, parrying the British bayonets with his sword. At last down he went before any one could reach him.
