General Mercer was an old friend and comrade of the commander-in-chief; he had been a companion of Prince Charles Edward in his romantic invasion of England in '45, a member of Braddock's unfortunate expedition, and wounded when that general's army was annihilated; and sometime commander of Fort Du Quesne, after its capture by General Forbes. He was detailed, with a small advance party comprising the remnants of Smallwood's Marylanders, Haslet's Delawareans, and Fleming's Virginians, and a small body of young men from the first families of Philadelphia, to the total number of three hundred, to continue up the road along the brook until he reached the main road, where he was to try and hold the bridge in order to intercept fugitives from Princeton, or check any retrograde movement of the troops which might have advanced toward Trenton. The little band had proceeded but a short distance on their way, when they unexpectedly came in sight of a column of the enemy. It was the advance of the British, a part of Von Donop's leading brigade, _en route_ for Trenton to assist Cornwallis in bagging the "old fox" according to orders,--the Seventeenth Regiment, under Colonel Mawhood. Mercer's troops being screened by the wood, their character was not visible to Mawhood, who conjectured that they must be a body of fugitives from the front. Under this impression, and never dreaming of the true situation, Mawhood promptly deployed his regiment and moved off to the left to intercept Mercer, at the same time despatching messengers to bring up the other two regiments, the Fortieth and Fifty-fifth, which had not yet left Princeton. Both parties rushed for a little rising ground on the edge of a cleared field, near the house of a peaceful Quaker named Clark. The Americans were nearer the goal than their opponents, and reached it first. Hastily deploying his column, Mercer sought shelter behind a hedge fence which crowned the eminence, and immediately opened up a destructive fire from his riflemen, which temporarily checked the advancing enemy. The British, excellently led, returned the fire with great spirit, and with such good effect that, after a few volleys, Mercer's horse was wounded in the leg and his rider thrown violently to the ground, Talbot's was killed under him, and several of the officers and men fell,--among them the brave Colonel Haslet, who was mortally wounded. In the confusion thus unfortunately caused, the Americans could hear sharp commands of the English officers, then the rattling of steel on the gun-barrels, and the next moment the red-coated men broke out of the smoke and, unchecked by a scattering fire from the Americans, gallantly rushed up at them with fixed bayonets. There were unfortunately no bayonets in this small brigade of the Continental army. A few of the men clubbed their muskets resolutely as the two lines met, and made a stout resistance; but the on-coming British would not be denied, and, as the
