That the principle as to providing for the safety of persons on board is liable to exceptions has been admitted by the Union Government itself. The Austrian Government believes, however, that destruction without warning is not only justifiable in cases of attempted escape or resistance. It would seem, to take one instance only, that the character of the vessel itself should be taken into consideration; thus merchant ships or other private craft, placed in the service of war operations, whether as transports or guardships, or with a military crew or weapons on board for the purpose of any kind of hostilities, should doubtless, according to general law, be liable to destruction without notice. The Austrian Government need not go into the question of how far a belligerent is released from any obligation as to provision for safety of human life when his opponent sinks enemy merchant vessels without such previous warning, as in the well-known cases, previously referred to, of the _Elektra_, _Dubrovnik_, _Zagreb_, etc., since, in this respect, despite its evident right, the Austrian Government itself has never returned like for like. Throughout the entire course of the war Austro-Hungarian warships have not destroyed a single enemy merchant vessel without previous warning, though this may have been of a general character. The theory of the Union Government, frequently referred to, also admits of several interpretations; the question arises, for instance, whether, as has frequently been maintained, only armed resistance can be held to justify destruction of ship and persons on board, or whether the same applies to resistance of another sort, as, for example, when the crew purposely refrain from getting the passengers into the boats (the case of the _Ancona_), or when the passengers themselves decline to enter the boats. In the opinion of the Austrian Government cases such as those last should also justify destruction of the vessel without responsibility for the lives of those on board, as otherwise it would be in the power of anyone on the vessel to deprive the belligerent of his right to sink the ship. For the rest it should also be borne in mind that there is no unanimity of opinion really as to when the destruction of enemy merchant tonnage is justifiable at all.
