The Acting Secretary of State to the Ambassador in Germany (Gerard)

[Telegram]

Your 515, October 15. The Government of the United States is obliged to dissent from the views of the German Government as expressed in your telegram in regard to the treatment to be accorded [Page 614] armed merchant vessels of belligerent nationality in neutral ports. The practice of a majority of nations and the consensus of opinion by the leading authorities on international law, including many German writers, support the proposition that merchant vessels may arm for defense without losing their private character and that they may employ such armament against hostile attack without contravening the principles of international law.

The purpose of an armament on a merchant vessel is to be determined by various circumstances, among which are the number and position of the guns on the vessel, the quantity of ammunition and fuel, the number and sex of the passengers, the nature of the cargo, etc. Tested by evidence of this character the question as to whether an armament on a merchant vessel is intended solely for defensive purposes may be readily answered and the neutral government should regulate its treatment of the vessel in accordance with the intended use of the armament.

This Government considers that in permitting a private vessel having a general cargo, a customary amount of fuel, an average crew, and passengers of both sexes on board, and carrying a small armament and a small amount of ammunition, to enjoy the hospitality of an American port as a merchant vessel, it is in no way violating its duty as a neutral. Nevertheless it is not unmindful of the fact that the circumstances of a particular case may be such as to cause embarrassment and possible controversy as to the character of an armed private vessel visiting its ports. Recognizing, therefore, the desirability of avoiding a ground of complaint this Government, as soon as a case arose, while frankly admitting the right of a merchant vessel to carry a defensive armament, expressed its disapprobation of a practice which compelled it to pass upon a vessel’s intended use, which opinion if proven subsequently to be erroneous might constitute a ground for a charge of unneutral conduct.

As a result of these representations no merchant vessels with armaments have visited the ports of the United States since the 10th of September. In fact from the beginning of the European wars but two armed private vessels have entered or cleared from ports of this country and as to these vessels their character as merchant vessels was conclusively established.

Please bring the foregoing to the attention of the German Government and in doing so express the hope that they will also prevent their merchant vessels from entering the ports of the United States carrying armaments even for defensive purposes though they may possess the right to do so by the rules of international law.
