Burgoyne considered renewing the attack the next day, but called it off when Fraser noted that many men were fatigued from the previous day's exertions. He therefore dug his army in, and waited for news that he would receive some assistance from the south, as a letter he received from General Clinton in New York on September 21 suggested that a movement up the Hudson would draw off some of Gates' army. Although he was aware of the persistent desertions that were reducing the size of his army and that the army was running short of food and other critical supplies, he did not know that the American army was also daily growing in size, or that Gates had intelligence on how dire the situation was in his camp.
