It is one of the few photographs of the actual moment of attack; an officer of the 9th Battalion the Cameronians (Scottish Rifles) leads the way out of a sap during the spring battles of 1917. © IWM.

It is an aerial photograph of a British gas attack in progress between Carnoy and Montauban in June 1916, shortly before the Somme offensive. Montauban, then still in German hands, is at the top left of the picture and Carnoy, behind British lines, is at the bottom right. © IWM.
