No society today would accept such a horrendous casualty count. At the beginning of the Battle of the Somme, on July 1, 1916, the British Army suffered 60,000 dead and wounded — in one day. It was arguably the worst butcher’s bill in military history, of army versus army. There is a very real sense in which the modern world — our world — was born between 1914 and 1918. Something changed in human sensibility. Soldiers wouldn’t be willing to engage in such slaughter. Toward the end of the First World War, even, tolerance for past norms had begun to end. In 1917, much of the French Army mutinied and refused to attack. They would defend but not attack. The days of cannon fodder were over forever as a result of that war, which is a further reason artists try to re-imagine it constantly.
