Members of the 20th Battery, Canadian Field Artillery, stand beside their pack horses, loaded with 18-pounder shells. This photograph was taken before the Battle of Vimy Ridge in April 1917. At Vimy, the Canadian gunners had an estimated 1.6 million shells and every one had to be carried forward to the guns.
