The battle on September 19 began when Burgoyne moved some of his troops in an attempt to flank the entrenched American position on Bemis Heights. Benedict Arnold anticipated the maneuver and placed significant forces in his way. Burgoyne did gain control of Freeman's Farm, but it came at the cost of significant casualties. Skirmishing continued in the days following the battle, while Burgoyne waited in the hope that reinforcements would arrive from New York City. Patriot militia forces continued to arrive, meanwhile, swelling the size of the American army. Disputes within the American camp led Gates to strip Arnold of his command.
