Sassoon had grown increasingly angry about the tactics being employed by the British Army and after a meeting with Bertrand Russell, John Murry Middleton and H. W. Massingham, he wrote Finished With War: A Soldier's Declaration, which announced that "I am making this statement as an act of wilful defiance of military authority because I believe that the war is being deliberately prolonged by those who have the power to end it. I am a soldier, convinced that I am acting on behalf of soldiers. I believe that the war upon which I entered as a war of defence and liberation has now become a war of aggression and conquest. I believe that the purposes for which I and my fellow soldiers entered upon this war should have been so clearly stated as to have made it impossible to change them and that had this been done the objects which actuated us would now be attainable by negotiation."
