In 1917 Bourlon Wood on the Western Front was the scene of fierce back-and-forth fighting between the British and the Germans, with British gains on at least one occasion thrown away by lack of proper follow-up. The Wood formed the left flank of the massive British tank attack at Cambrai, the first of its kind, on November 20, 1917. Bourlon Wood once again came into prominence in September 1918 with the attack of the Canadian Corps against the German defenders, an action that rivaled the Canadian assault on Vimy Ridge.
