The Dominion of Canada, Australasia and South Africa would have found themselves in the position of isolated nations, dependent for the time being upon their own resources for defense. Their loyalty to the British Empire has not been the least wonderful of the many wonderful results of this war. They have sent legions of volunteers across the seas to France and Gallipoli to fight beside the British and the French. As for Hongkong, the Straits Settlements, Ceylon, India, and all the colonies of the empire, they would have been Germany's for the occupation. Such is the meaning of sea power. But the British navy being superior to the German, held Germany in siege.
Germany must make the best possible use of her comprehensive industrial organization and of her preparedness for war and throw the greatest possible number of men into the fighting line at the earliest possible moment. She was practically in a race against time; and time was with the Allies. While they retained command of the sea the United States and other neutral nations overseas, once their plants for manufacture were completed, could pour out supplies of munitions.
Germany's foreign trade was practically at a standstill. From the port of Hamburg her argosies of manufactures no longer went forth to the world in return for raw material. Her many ships, from the enormous passenger steamers to the small tramps which had brought her tribute with their carrying trade, were idle. She could manufacture, then, only for home consumption and all her plants that had been manufacturing for export began producing for her armies. The energies of the one hundred and twenty-five millions of people, men, women and children, in Germany and Austria-Hungary were wholly occupied in making war. Their object must be to push the walls back as far as they could, and so to punish Russia or France that one or the other would yield a separate peace. The aim of British statesmanship must be to hold the Allies together at any expense and keep Germany from breaking the siege. If more nations could be brought in against Germany, that would strengthen the siege lines and lengthen the front the Central Powers were building.
Through the winter of 1914-15 the diplomats of the Allies and the Central Powers in Rome fought for Italy's hand with all the skill and resources of trained European diplomacy. Responding to the sentiment for the recovery of Trentino and Trieste which she considered ethnologically and geographically a part of her domain she was to throw in her fortunes with the Allies against her old enemy, Austria.
