From the foregoing it appears that the rule as to warning being given to the vessel itself before such vessel is sunk is subject to exceptions of various kinds under certain circumstances, as, for instance, the cases cited by the Union Government of flight and resistance, the vessel may be sunk without any warning; in others warning should be given before the vessel sails. The Austrian Government may then assert that it is essentially in agreement with the Union Government as to the protection of neutrals against risk of life, whatever may be the attitude of the Washington Cabinet towards some of the separate questions here raised. The Austrian Government has not only put into practice throughout the war the views it holds in this respect, but has gone even farther, regulating its actions with the strictest care according to the theory advanced by the Washington Cabinet, although its assurance as published only stated that was “essentially in agreement” with the Union Government’s views. The Austrian Government would be extremely satisfied if the Washington Cabinet should be inclined to assist it in its endeavours, which are inspired by the warmest feelings of humanity, to save American citizens from risk at sea by instructing and warning its subjects in this direction.
Then, as regards the circular verbal note of February 10 of this year concerning the treatment of armed enemy merchant vessels, the Austrian Government must in any case declare itself to be, as indicated in the foregoing, of the opinion that the arming of trading ships, even when only for the purpose of avoiding capture, is not justified in modern international law. The rules provide that a warship is to approach an enemy merchant vessel in a peaceable manner; it is required to stop the vessel by means of certain signals, to interview the captain, examine the ship’s papers, enter the particulars in due form and, where necessary, make an inventory, etc. But in order to comply with these requirements it must obviously be understood that the warship has full assurance that the merchant vessel will likewise observe a peaceable demeanour throughout. And it is clear that no such assurance can exist when the merchant vessel is so armed as to be capable of offering resistance to a warship. A warship can hardly be expected to act in such a manner under the guns of an enemy, whatever may be the purpose for which the guns were placed on board. Not to speak of the fact that the merchant vessels of the Entente Powers, despite all assurances to the contrary, have been proved to be armed for offensive purposes, and make use of their armament for such purposes. It would also be to disregard the rights of humanity if the crew of a warship were expected to surrender to the guns of an enemy without resistance on their own part. No State can regard its duty to humanity as less valid in respect of men defending their country than in respect of the subjects of a foreign Power.
