Since Freeman's Farm, the American position had increased in strength. Gates now had 11,000 men and outnumbered Burgoyne by two to one. Burgoyne's plan was to punch through the American left wing, and by a rapid march reach Albany before Gates could react. Burgoyne was still hoping to find British troops at Albany, but General Clinton's attack from New York never reached Albany, stalling once it captured the Highland forts upriver from New York. A second weakness in the plan was that Burgoyne's army had shown no ability to move quickly, and was in very poor condition. Burgoyne's plan was a desperate attempt to avoid disaster.
Unsure of the American positions, Burgoyne decided to start the day by sending out a reconnaissance in force. Fifteen hundred men with ten artillery pieces advanced slowly towards the American lines. After an advance of three-quarters of a mile, they had discovered nothing. The advance was halted and the troops formed into a line, then stopped to wait.
It was now the Americans turn to act. Their scouting was far superior to the British, and news of the unsupported advance soon reached Gates, who ordered Poor's brigade (New Hampshire regulars) to attack the British left. This attack was supported by Daniel Morgan's regiment, which was able to reach the British rear. Also prominent in the American attack was Benedict Arnold. Although he had been relieved of his command by Gates, Arnold had remained with the army, and when battle developed Arnold dashed into the fray, and soon appears to have taken command of the American attack. As a battlefield commander he may have been the best on either side during the war. He led from the front, and the American troops were willing to follow him into battle in a way that few other commanders could imitate.
Under the stress of the repeated American attacks, the British line crumbled. General Simon Fraser was killed by sniper fire, ordered by Arnold, as was one of Burgoyne's aids sent to order a retreat. Burgoyne was initially able to get the main body of the army back into their entrenchments at Freeman's Farm in remarkably good condition, but once again Arnold came to the fore, leading a wild attack on the British right, which succeeded in capturing part of the British defences. However, after Arnold was forced off the field by a serious wound the American attacks began to tire, and the British managed to avoid total disaster.
Even so, the days fighting left the British position at Freeman's Farm untenable. What had started as an attempt to punch a hole in the American lines had ended with the British being forced to retreat from their own camp. Burgoyne was now faced with the inevitability of surrender.
