It had been necessary, for some time, to send out large parties to cover any provisions destined for the British camp; General Burgoyne determined, therefore, to select a heavy detachment of his best troops, for the ostensible purpose of covering a forage, which should move to the left of the American lines, and, after making a reconnaissance, endeavor to dislodge the Americans, or force a passage through the intrenchments: in the event of being successful, the whole army was to follow.

Entrusting the guard of the camp upon the heights near Freeman’s farm to Brigadiers Hamilton and Specht, and the intrenchments and redoubts upon the flats to Brigadier Gall, about eleven o’clock on the seventh of October, Gen. Burgoyne placed himself at the head of fifteen hundred regulars, the flower of his army, with two twelve-pounders, two howitzers, and six six-pounders, and moved toward the American left. His best officers, Majors-General Phillips and Reidesel and Brigadier Frazer, accompanied the detachment, and seconded the command of the general-in-chief. Having proceeded within three-fourths of a mile of the American camp at the northwest, they displayed and sat down in double ranks, with their arms between their legs. While the foragers of the party were cutting straw in a wheat-field, several officers from the top of a cabin were engaged in reconnoitering, with their glasses, the American left, which was concealed in a great measure from their view by the intervening woods.

General Gates having received intelligence of the movements and position of the enemy, and penetrating his intentions, made arrangements for an immediate attack. In the meantime, a party of Indians, Canadians and Provincials, scouring the woods on the British flank, fell in with the American pickets near the Middle Ravine; a sharp conflict ensued, which drew to the support of the scouting party a strong corps of grenadiers, when the Americans were driven back to the intrenchments. A brisk action ensued, without any material advantage on either side, when a corps of Morgan’s riflemen appeared, whom the Indians and Canadians always held in great terror, and the British retreated to their line, which was forming, pursued by the Americans.

Gen. Burgoyne formed his line of battle across an open field; the left wing consisting of the grenadiers, under Major Ackland, and the artillery, under Major Williams, resting upon a ridge of ground bordered with wood, and covered in front by the head of the Middle Ravine; the centre, under Generals Phillips and Reidesel, was composed of British and German battalions; the right wing, consisting of the light infantry under Lord Balcarras, extended toward the southwest to the foot of a hill densely wooded, and was covered by a worm fence; while, in advance of the right wing, a strong body of flankers was posted under the brave General Frazer, to fall upon the American flank and rear, as the other troops made the attack upon the left.

General Gates ordered Col. Morgan with his corps to commence the action. That sagacious officer proposed and was permitted with his command to march by a circuitous route, and under cover of the woods to gain the hill that ran near the enemy’s right and its advance, and to make an attack in front and flank upon the advanced party under Frazer, and the British right, while the brigade of General Poor opened its fire upon the British left. Allowing time for Morgan to reach his destination, Gen. Poor led on his brigade to the British left, having ordered his men to reserve their fire till some time after they began to rise the hill on and around which the artillery and a part of the grenadiers were posted. As soon as they came in sight they were saluted by the enemy with a shower of grape-shot and musket balls, which overshot them, however, and spent their fury upon the tops of the trees. The Americans rushed on with a shout, and delivering their fire, in quick succession, opened to the right and left, that they might gain the cover of the trees that enclosed the ridge on which the artillery was placed. Here a close and bloody conflict ensued, with the continual discharge of artillery and small arms. Nothing could exceed the bravery of the Americans; they rushed upon the enemy’s guns, which, by repeated charges, were taken and retaken, till the dead and dying were strewed all around. One field-piece was taken for the fifth time, when the brave Cilley in a fit of exultation mounted astraddle of it, and having “sworn it true to the American cause,” turned it upon the enemy, and galled them with their own ammunition, which in their precipitancy they had left behind them. After a long and obstinate contest, in which the grenadiers and artillerists suffered very severely, Major Ackland, the commander of the former, was wounded, and Major Williams, the commander of the latter, was taken prisoner, upon which they broke and fled with consternation.

Simultaneously with the opening of the fire of Poor’s brigade upon the British left, the gallant Col. Morgan, like a torrent, rushed down from the hills that skirted the advance of the British right, and pouring in a rapid and destructive fire, soon drove it back upon the right wing, then, wheeling suddenly to the left, he took the British right in flank, with irresistible impetuosity, and threw their ranks into confusion. While thus disordered, Major Dearborn led up two regiments of fresh troops against them, when, assailed both in flank and front, they broke and fled. The Earl of Balcarras rallied them again, and re-formed them, but overpowered by superior numbers, the whole right wing vacillated and gave way.

While the two wings were thus closely engaged, the centre, composed principally of Hessian troops, had as yet taken no part in the action, for the British commander feared, as the American front extended beyond the grenadiers, that, by breaking his centre, he would give an opportunity to the Americans to cut off and surround a part of his forces. As the battle was thus going on, and indecisive, Gen. Arnold, who found it impossible to restrain himself, swore that he would “put an end to the action,” and galloped off in hot haste to the field, upon a magnificent coal-black steed. Gen. Gates, fearful lest he might “do some rash action,” as he expressed himself, sent Major Armstrong after him to recall him, but the messenger could not reach him to deliver his summons, so quick and varied were his motions, and so perilous the track of his onward course. Placing himself at the head of three regiments, who readily obeyed their former commander, Gen. Arnold advanced with great vigor and attacked the British centre. The Hessians received the assailants with becoming spirit, and, at first, made a brave resistance; but the second charge upon them was furious and irresistible; Arnold with some daring followers dashed into their thickest ranks, carrying with them death and dismay, and the Hessians broke and fled with great precipitancy and consternation.

While the two wings and centre were thus engaged, and the battle was hotly maintained along the whole line, the bravery and skill of the gallant Gen. Frazer was everywhere conspicuous. When the troops began to waver, he encouraged them; when falling back, he rallied them again; when broken, he re-formed them. On his magnificent iron-grey steed, he passed along the line continually, and wherever he appeared he restored order and inspired confidence; the fate of the battle seemed to hang upon his energy, skill and bravery. The sagacious Col. Morgan saw this, and, with more prudence than generosity, called a file of his best marksmen, and said to them, “That gallant officer is General Frazer; I admire and honor him, but it is necessary that he should die—take your stations in that cluster of bushes, and when he passes down the line again, do your duty.” In a few moments the brave and accomplished Frazer fell mortally wounded, and was carried to the camp, a grenadier on each side of his horse supporting him. At his fall a panic pervaded the enemy, and a reinforcement of three thousand New York militia simultaneously arriving, under Gen. Ten Broeck, the whole line under Gen. Burgoyne broke and fled to their encampment, covered in their retreat by Generals Phillips and Reidesel. The Americans pursued them in hot haste to their very intrenchments, and assaulted the works, though possessed neither of battering nor field artillery.

Along the whole line of the British encampment there now rages a storm of grape-shot and musketry; yet the brave Americans, exposed to the deadly fire, or sheltered in part by trees, stumps, and rocks, or covered in gullies formed by the rains, continue the fight with great obstinacy, and many brave men fall on both sides. In this scene of blood and carnage, Arnold was a conspicuous actor. Incited by wounded pride, anger, and military enthusiasm, he fought with reckless bravery, exposed himself with inconsiderate rashness, furiously at times brandished his sword to the danger of his own men, animated his soldiers by the most impassioned appeals, and leading them on, snatched laurels from the very hands of death and danger. With a part of Glover’s and Patterson’s brigades, he rushed on to the works possessed by the light infantry under Lord Balcarras, and a portion of the line, and assaulting, a large abattis which he carried at the point of the bayonet, endeavored to make an opening into the British camp; but, after a sanguinary contest, he was forced to fall back. Leaving the troops now engaged at a greater distance, he dashes furiously on toward the right flank defence, receiving as he passes the fire of the contending armies unhurt.

Gen. Learned, with his brigade, sheltered by a sudden depression of the ground, which covered his men breast high, had been engaged at a long fire with the Germans of the right flank defence, who poured upon them a continual discharge of grape-shot. He now advanced, for nearer contest, his brigade in open column, with Col. Jackson’s regiment in front, in command of Lieut Col. Brooks, to make an assault at an opening between the light infantry, under Lord Balcarras, and the German right flank defence. This part of the lines was occupied by Canadians and Provincials, and was defended by two stockade redoubts. Arnold, in passing on to the British right, met Learned’s brigade advancing, and placing himself at the head of the brigade, orders Brooks, with two platoons, to attack the stockades, while the other troops assault in front. The engagement is now general and sanguinary, the cannon thunder along the line, the peals of musketry are continuous, and the sharp rattle of the rifle is incessant, while the bomb lights up with its red glare, the atmosphere darkened with the smoke of battle and the shades of coming eve.
