The First World War was the first large-scale industrial war which saw its belligerents grapple with modernity. By the beginning of 1918 the British were faced with a particularly challenging strategic picture. Their Russian partners had withdrawn from the war and were negotiating a settlement with the Central Powers. The French were recovering from a series of strikes which fuelled British concern over how worn out the French Army might be. The Italians were regrouping after a devastating attack by the Central Powers at Caporetto. While the United States had entered the war on the side of the Entente, they were arriving too slowly to reassure their partners that they could tip the balance of the war in the Entente’s favour in the near term.
