William Kydd worked at branches throughout the Maritimes and enlisted in May 1940. He served with the 2nd Canadian Infantry Division and saw action in France, Belgium, Holland and Germany. After the war, William Kydd returned to The Commerce at the Antigonish branch in Nova Scotia.
Excerpt from the official citation of Charles Kydd, Canada Gazette, 12th May 1945:
On 9 February, 1945, 'D' Troop of 56 Battery, commanded by Lieutenant Kydd, was in support of 2 Monmouthshire Regiment, which came under heavy fire from two enemy self-propelled guns along the north side of the Reichswald. Immediately, and without seeking cover for his troop, Lieutenant Kydd ordered his guns to engage the enemy. So effective was the fire which he brought down that both enemy armoured fighting vehicles were put out of action and the Monmouthshire Regiment continued the advance.
