On 10 May, 36 soldiers and two officers of the 26th were captured at Fort Ticonderoga by a force led by Ethan Allen and Benedict Arnold. A second detachment at Fort Crown Point was taken without incident the next day. The main force of the 7th and 26th regiments in Canada was soon shifted towards Fort Saint-Jean, in Quebec. An expedition by 150 men under Allen to capture Montreal was defeated on 25 September by thirty-six Cameronians – the entire regular garrison of the city – and a local militia force.
