Gates, following the removal of Arnold from the field command, assumed command of the American left and gave the right to General Lincoln. When American scouts brought news of Burgoyne's movement to Gates, he ordered Morgan's riflemen out to the far left, with Poor's men (1st, 2nd, and 3rd New Hampshire) on the left; the 2nd and 4th New York Regiments on the right, and Learned's 1st New York, 1st Canadian, 2nd, 8th and 9th Massachusetts Regiments, plus militia companies, in the center. A force of 1,200 New York militia under Brigadier General Abraham Ten Broeck was held in reserve behind Learned's line. In all, more than 8,000 Americans took the field that day, including about 1,400 men from Lincolns command that were deployed when the action became particularly fierce.
