It is difficult to realise all that the transport of millions of men, organised as armies and provided with all that armies require, has meant to the Allies, or to bring home to ourselves a full sense of what the responsibilities of the Navy have been in safeguarding them. The armies of Frederick and Napoleon were pygmies compared with the vast hosts which are set in the field to-day. When Frederick invaded Silesia he had with him not more than 30,000 men. The motley army with which Napoleon invaded Russia—the greatest that had ever been brought under a single command—did not greatly exceed 600,000 on a liberal computation. Wellington in the Peninsula never commanded 50,000 men. But in March, 1916, Mr. Balfour, then First Lord of the Admiralty, said that 4,000,000 combatants had already been transported under the guardianship of the British Fleet, with 1,000,000 horses and other animals, 2,500,000 tons of stores, and 22,000,000 gallons of oil, for British use and the use of the Allies. In January, 1917, Admiral Sir John Jellicoe, First Sea Lord, said that over 7,000,000 men had been transported, together with all the guns, munitions, and stores they required. Six months later, when the United States troops began to arrive, the figure may be estimated to have reached 10,000,000. The victory of Germany would have been swift and decisive if the great armies represented by these figures had not come to the support of France. French troops from Northern Africa and the East also joined her brave army, because transport in the Mediterranean was secure. The great army of Russia could have made no offensive movement if she had not received the immense supplies of guns, munitions, motors, and other material which came to her from abroad. Because of British supremacy at sea and the shipping that consequently came there, Archangel, from being a sleepy harbour, developed into one of the busiest ports on the continent of Europe. Italy could have made no headway if many of the things she required had not come to her by sea. Greece would have remained permanently on the side of the enemy if sea-power and the troops transported there had not rallied her to the Allies. The German colonies would not have been occupied if fleets had not carried to them the troops for their subjection. England, by virtue of sea command guaranteed by her Fleet, has gathered her armies from India, Canada, Australia, New Zealand, and from every colony and possession, and has sent them to serve in France, Belgium, Greece, Gallipoli, Egypt, Palestine, Macedonia, Mesopotamia, and Africa. Not a soldier has gone afloat but a seaman has carried him on his back.
