In the wake of this action, he was appointed commander-in-chief of the British army in North America and colonel-in-chief of the 60th (Royal American) Regiment in September 1758. Amherst then led an army against French troops on Lake Champlain, where he captured Fort Ticonderoga in July 1759, while another army under William Johnson took Niagara also in July 1759 and James Wolfe besieged and eventually captured Quebec with a third army in September 1759. Amherst served as the nominal Crown Governor of Virginia from 12 September 1759.
