Canadians in a captured trench at Hill 70, 1917 (b/w photo)

Canadians in a captured trench at Hill 70, 1917. Photograph, World War One, Western Front (1914-1918), 1917. Between 15 and 25 August 1917 the Canadian Corps attacked the high ground at Hill 70 on the outskirts of Lens in order to draw German troops away from the ongoing Battle of Passchendaele and inflict as many casualties on the enemy as possible. Although the operation prevented the Germans from deploying some of their reserves to Passchendaele, it failed to draw off troops from the latter engagement. Canadian losses were as high as those sustained by the Germans. An attempt by the Canadians to extend their position into the city of Lens itself also failed.
