Of course, the German submarines could not completely blockade the coasts of the British Isles, nor could they take into port the ships which they stopped and searched. In the latter case they might be justified in sinking the ships, but they would be guilty of crime if they did not save the crews and passengers. A submarine cannot possibly take off the crews of merchant vessels, for it has no accommodation for them. Von Tirpitz's plan was piracy, and nothing else. In order to find an excuse, the Germans declared that all the wheat and flour coming into Germany from abroad belonged to the Government. The British now seized the cargoes of ships thus laden, because they were the property of an enemy Government. Then the Germans began to call heaven and earth to witness that Great Britain was trying to starve German women and children. Horrible pictures were painted of innocent people perishing of hunger. A German newspaper put the enemy's view in a nutshell when it said, "England wants to employ every means to shorten the war. The number of lives that would be lost if she could starve Germany is nothing to her. . . . Whether we wish it or not, we must seek to destroy England's life-nerve--namely, her merchant shipping." How she attempted to do this we shall read in the next chapter. CHAPTER XI. THE SINKING OF THE "LUSITANIA." The Germans were quite right in speaking of our mercantile marine as our "life-nerve." In 1913 we had nearly 39,600 merchant vessels, with a tonnage of more than 14,000,000 tons. You will get some idea of the vastness of our overseas trade when I tell you that the tonnage of ships owned in Liverpool alone exceeds that of the German Empire. On an average about 1,400 merchant vessels enter and leave our ports every week. This means that the submarines which were now going to destroy our "life-nerve" were presented with about two hundred targets a day.
