In 1916 the Allies were ready for a combined advance, Germany was aware of their policy, and tried to anticipate it by her great attack on Verdun in February of that year—a battle which was fiercely contested for months, and finally ebbed away about midsummer. By that time Austria’s attack on Italy had also failed and the Allied advance begun. The Russians won great successes in Galicia, and the British and French on the Somme dealt the German armies a blow from which they never really recovered. In Rumania, on the other hand, Germany had a temporary success; but by the close of 1916 it was clear to her commanders that unless some miracle happened the war would end with an Allied victory during the following year. That miracle happened, in the form of the Russian revolution in the spring of 1917. Thereafter Germany was able to get rid of the war on her eastern frontier and to throw all her strength against the West. During that spring and summer she staved off the French and British attacks at Arras, at Ypres, and on the Aisne, and in the autumn of 1917 she was ready to begin her own offensive. Her first blow was directed against Italy, whom she drove back fifty miles from the Isonzo to the Piave, with immense losses. In March 1918 she struck her great blow in the West. With a large superiority in men and guns, she attacked the British at St. Quentin, and forced them to retreat almost to the gates of Amiens. It was a success, but only a limited success, and with this last stroke her energy began to ebb. Foch was now Commander-in-Chief of the Allies, and with great skill he maintained a stubborn defensive till such time as he had gathered strength for a counter-attack. Meantime the new armies of America were arriving in France at the rate of 10,000 a day. In July Germany struck her last blow on the Marne in a frantic effort to reach Paris. That blow was likewise warded off, and three days later the Allied counter-offensive began. Then in a series of great attacks all the prepared German defences were broken down. By the early days of October Turkey and Bulgaria had been defeated in the East, and the surrender of Austria followed before the end of the month. Finally, on November 11, 1918, Germany herself was forced to sue for an armistice in order to save her armies from destruction. An armistice was granted, but its terms involved an unconditional surrender to the will of the Allies.
