"Nevertheless different port authorities in the United States have refused to supply the necessary fuel to merchant vessels in which it might be carried to German ships of war on the high seas or in other neutral ports. According to the principles of international law already mentioned, there is no need for a neutral State to prevent the transport of fuel in this way; such a State then ought not to hold up merchant ships loaded in this way nor interfere with their freedom of movement, once it has countenanced the supply of contraband to the enemy. The only case in which it would be the duty of such a nation to hamper the movements of these ships in this one-sided fashion would be one in which such traffic might be turning the ports into German naval bases. This might perhaps have been the case if German coal depots had been situated at these ports, or if the ships used them for a regular calling port on their way to the German naval forces. It is, however, unnecessary to urge that the occasional sailing of a merchant ship with coal for German ships of war does not make a port into a base for German naval enterprises out of keeping with neutrality. "Our enemies are obtaining contraband of war from the United States, in particular rifles, to the value of many milliards of marks; this is within their rights. But toleration becomes serious injustice if the United States refuses to allow the occasional provisioning of our ships of war from her ports. This would mean unequal treatment of the combatants and a recognized rule of neutrality would be infringed to our disadvantages." This memorandum played an important part in the subsequent negotiations, because Mr. Flood, the president of the Committee for Foreign Affairs of the American House of Representatives, interpreted it as amounting to a German agreement to the supply of arms and ammunition to her enemies. In view of the situation in the United States, it was to our interest to leave the struggle for a prohibition of the munitions traffic to our American friends. The efforts of Senator Stone in this direction are well known, and have been recently quoted before the Commission of the German National Assembly. If a considerable number of influential Americans took up the case for the prohibition there was far more hope of bringing it about than if it was apparent that the American Government were surrendering to German pressure. The pacifist Mr. Bryan was very sensitive on this point and visited me frequently to assert his neutrality.
