The Great Battle on the Western Front: open warfare - an action at Bucquoy, a village on the Arras-Albert road. Stand by British infantry at Bucquoy: a thin khaki line pouring rifle and machine-gun fire into on-rushing German hordes seen advancing from Longast Wood in the right background towards the Nissen huts and bayonet practice gallows on the left. In the distance are the ruins of Ablainzeville. British infantry in the foreground. British artillery officer in the right foreground behind a rampart of ammunition boxes, giving orders to the signaller to transmit to the battery behind. Two German sausage-balloons in the air over Longast Wood.
