This brilliant victory at Bennington had important consequences. It checked Burgoyne's advance until he could get his supplies, and it decided that Lincoln's militia could get in his rear and cut off his communications with Ticonderoga. It furthermore inspired the Americans with the exulting hope that Burgoyne's whole army could be surrounded and forced to surrender.
St. Leger in the Mohawk valley.
If, however, the British had been successful in gaining the Mohawk valley and ensuring the supremacy over that region for the Tories, the fate of Burgoyne might have been averted. The Tories in that region, under Sir John Johnson and Colonel John Butler, were really formidable. As for the Indians of the Iroquois league, they had always been friendly to the English and hostile to the French; but now, when it came to making their choice between two kinds of English—the Americans and the British, they hesitated and differed in opinion. The Mohawks took sides with the British because of the friendship between Joseph Brant and the Johnsons. The Cayugas and Senecas followed on the same side; but the Onondagas, in the centre of the confederacy, remained neutral, and the Oneidas and Tuscaroras, under the influence of Samuel Kirkland and other missionaries, showed active sympathy with the Americans. It turned out, too, that the Whigs were much stronger in the valley than had been supposed.
Battle of Oriskany, Aug. 6, 1777.
After St. Leger had landed at Oswego and joined hands with his Tory and Indian allies, his entire force amounted to about 1700 men. The principal obstacle to his progress toward the Hudson river was Fort Stanwix, which stood where the city of Rome now stands. On the 3d of August St. Leger reached Fort Stanwix and laid siege to it. The place was garrisoned by 600 men under Colonel Peter Gansevoort, and the Whig yeomanry of the neighbourhood, under the heroic General Nicholas Herkimer, were on the way to relieve it, to the number of at least 800. Herkimer made an excellent plan for surprising St. Leger with an attack in the rear, while the garrison should sally forth and attack him in front. But St. Leger's Indian scouts were more nimble than Herkimer's messengers, so that he obtained his information sooner than Gansevoort. An ambush was skilfully prepared by Brant in a ravine near Oriskany, and there, on the 6th of August, was fought the most desperate and murderous battle of the Revolutionary War. It was a hand to hand fight, in which about 800 men were engaged on each side, and each lost more than one-third of its number. As the Tories and Indians were giving way, their retreat was hastened by the sounds of battle from Fort Stanwix, where the garrison was making its sally and driving back the besiegers. Herkimer remained in possession of the field at Oriskany, but his plan had been for the moment thwarted, and in the battle he had received a wound from which he died.
St. Leger's flight, Aug. 22, 1777.
Benedict Arnold had lately been sent by Washington to be of such assistance as he could to Schuyler. Arnold stood high in the confidence of both these generals. He had shown himself one of the ablest officers in the American army, he was especially skilful in getting good work out of raw troops, and he was a great favourite with his men. On hearing of the danger of Fort Stanwix, Schuyler sent him to the rescue, with 1200 men. When he was within twenty miles of that stronghold, he contrived, with the aid of some friendly Oneidas and a Tory captive whose life he spared for the purpose, to send on before him exaggerated reports of the size of his army. The device accomplished far more than he could have expected. The obstinate resistance at Oriskany had discouraged the Tories and angered the Indians. Distrust and dissension were already rife in St. Leger's camp, when such reports came in as to lead many to believe that Burgoyne had been totally defeated, and that the whole of Schuyler's army, or a great part of it, was coming up the Mohawk. This news led to riot and panic among the troops, and on August 22 St. Leger took to flight and made his way as best he could to his ships at Oswego, with scarcely the shred of an army left. This catastrophe showed how sadly mistaken the British had been in their reliance upon Tory help.
The battle of Bennington was fought on the 16th of August. Now by the overthrow of St. Leger, six days later, Burgoyne's situation had become very alarming. It was just in the midst of these events that Gates arrived, on August 19, and took command of the army at Stillwater, which was fast growing in numbers. Militia were flocking in, Arnold's force was returning, and Daniel Morgan was at hand with 500 Virginian sharpshooters. Unless Burgoyne could win a battle against overwhelming odds, there was only one thing that could save him; and that was the arrival of Howe's army at Albany, according to the ministry's programme. But Burgoyne had not yet heard a word from Howe; and Howe never came.
Why Howe failed to coöperate with Burgoyne.
This failure of Howe to coöperate with Burgoyne was no doubt the most fatal military blunder made by the British in the whole course of the war. The failure was of course unintentional on Howe's part. He meant to extend sufficient support to Burgoyne, but the trouble was that he attempted too much. He had another plan in his mind at the same time, and between the two he ended by accomplishing nothing. While he kept one eye on Albany, he kept the other on Philadelphia. He had not relished being driven back across New Jersey by Washington, and the hope of defeating that general in battle, and then pushing on to the "rebel capital" strongly tempted him. In such thoughts he was encouraged by the advice of the captive General Lee. That unscrupulous busybody felt himself in great danger, for he knew that the British regarded him in the light of a deserter from their army. While his fate was in suspense, he informed the brothers Howe that he had abandoned the American cause, and he offered them his advice and counsel for the summer campaign. This villainy of Lee's was not known till eighty years afterward, when a paper of his was discovered that revealed it in all its blackness. The Howes were sure to pay some heed to Lee's opinions, because he was supposed to have acquired a thorough knowledge of American affairs. He advised them to begin by taking Philadelphia, and supported this plan by plausible arguments. Sir William Howe seems to have thought that he could accomplish this early in the summer, and then have his hands free for whatever might be needed on the Hudson river. Accordingly on the 12th of June he started to cross the state of New Jersey with 18,000 men.
