The Expedition Against Fort Schuyler: Herkimer and Willett
St. Leger had intelligence of the advance of Herkimer and detached a division of Johnson's Greens, under Major Watts, Colonel Butler with his Rangers, and Brant with a strong body of Indians, to intercept him and prevent an attack upon his intrenchments. Before the arrival of Herkimer's messenger, Gansevoort had observed the silence of the enemy's camp, and also the movement of a portion of his troops along the margin of a wood down the river. The arrival of the courier dispelled all doubts as to the destination of the detachment, and the signal-guns were immediately fired. Herkimer had informed Gansevoort, by the messenger, that he intended, on hearing the signals, to cut his way to the fort through the circumvallating camp of the enemy, and requested him to make a sortie at the same time. This was done as soon as the arrangement could be made, and a detachment of two hundred men .. was detailed for the purpose, who took with them an iron three-pounder. Fifty men were also added, to protect the cannon, and to act otherwise as circumstances might require.. Rain was falling copiously while preparations for the sortie were in progress, but the moment it ceased Willett sallied out and fell furiously upon that portion of the camp occupied by Sir John Johnson and his Royal Greens, a detachment of whom, as we have seen, had been sent to oppose the approach of Herkimer. The advanced guard, unable to withstand the impetuosity of the attack, was driven in; and so suddenly was Sir John's camp assailed that he was not allowed time to put on his coat. He endeavored to bring his troops into order, but they fled in dismay. The Indian camp was then assaulted, and in a few moments the savages, too, were scattered. Sir John and his troops fled across the river, to the temporary camp of St. Leger, and the Indians buried themselves in the deep forest near. No less than twenty-one wagon-loads of spoil, consisting of clothing, blankets, stores, camp-equipage, five British standards, the baggage of Sir John, with all his papers, and those of other officers, containing every kind of information necessary to the garrison, were captured. Having secured their prize, Willett and his party returned to the fort without the loss of a man. The five British colors were raised in full view of the enemy, upon the flag-staff, beneath the uncouth American standard, and the whole garrison, mounting the parapets, made the forest ring with three loud cheers. This chivalrous exploit was duly noticed by Congress, and an elegant sword was presented to Colonel Willett in the name of the United States.
General Herkimer, in the mean while, had moved from the mills, at the mouth of Oriskany Creek, towards the fort, entirely unconscious of the ambuscade that, in a deep ravine two miles distant, awaited his approach. The morning was dark, sultry, and lowering. His troops, composed chiefly of the militia regiments of Colonels Cox, Paris, Visscher, and Klock, were quite undisciplined, and their order of march was irregular and without precaution. The contentions of the morning had delayed their advance until about nine o'clock, and the hard feelings that existed between the commander and some of his officers caused a degree of insubordination which proved fatal in its consequences. Brant and his tory associates had learned from their scouts the exact route the patriots had taken, and arranged an ambuscade accordingly. A deep ravine crossed the path of Herkimer in a north-and-south direction, extending from the high grounds on the south to the river, and curved towards the east in a semicircular form. The bottom of this ravine was marshy, and the road crossed it by means of a causeway of earth and logs. On each side of the ravine the ground was nearly level, and heavily timbered. A thick growth of underwood, particularly along the margin of the ravine, favored concealment. It was upon the high ground on the western side of this ravine that the ambush of tories and Indians was laid, in such a manner that the causeway was surrounded by them, as by a circle, leaving only a small segment open where the road entered. Unsuspicious of the proximity of the enemy, the whole body of provincials, except the rear-guard, composed of Visscher's regiment, descended into the ravine, followed by the baggage-wagons. Brant gave a signal, and in an instant the circle closed, the war-whoop was sounded, and spear and hatchet and deadly rifle-ball fell upon the patriots like hail from the clouds that hovered over them. The rear-guard, in fulfilment of Herkimer's prediction, instantly fled, and left their companions in the ravine to their fate. They were pursued by the Indians, and probably suffered more in their cowardly flight than if they had boldly aided their environed companions in arms.
This sudden onslaught produced great confusion in the patriot ranks, but they soon recovered, and fought with the courage and skill of veteran troops. The slaughter, however, was dreadful. Herkimer was severely wounded at the commencement of the action, and Colonel Cox and Captain Van Slyk were killed at the first fire. A musketball passed through and killed the horse of the general, and shattered his own leg just below the knee. With perfect composure and cool courage, he ordered the saddle to be taken from his slaughtered horse and placed against a large beech-tree near. Seated there, with his men falling like autumn foliage, and the bullets of the enemy, like driving sleet, whistling around him, the intrepid general calmly gave his orders, and thus nobly rebuked the slanderers who called him a coward.
