German dugout at Bourlon Wood, France, September 1918. Part of Bourlon Wood after its capture by the Canadian Corps on 27 September 1918. To the left is the wood-lined entrance to a German dugout. In the centre there are the burning remains of a German heavy gun, identified in the caption as a Howitzer. The attack on Bourlon Wood was the beginning of the Cambrai offensive, a highly successful thrust towards the German Hindenburg Line by the British First and Third Armies. Bourlon Wood was captured by the Canadian Corps under the command of General Sir Arthur Currie (1875-1933). [Original reads: 'A Dug-out fire in Bourlon Wood. An 8.3 German Howitzer blown over by the explosion of a dump near it. Good Canadian artillery fire is sure proof here.'].
