"On January 22, 1915, the steamship Durward was stopped by a U-boat about thirteen miles from the lightship Maas. The crew was ordered to take to the boats, no time being allowed for the removal of their private belongings. The submarine then towed the boats to a safe distance, ordered them to wait there while it sank the ship, and them towed them onwards in the direction of the lightship. A week later (January 30) two ships, the Ben Cruachan and the Linda Blanche, were sunk, in both cases with reasonable consideration for the safety of the crews. . . . the Kölnische Zeitung, about the middle of the month, had published an article declaring that 'in future German submarines and aircraft would wage war against British mercantile vessels without troubling themselves in any way about the fate of the crews.'"
Capturing enemy mercantile ships was legitimate according to international war. The captured vessel was then to be taken to a neutral port for adjudication by a Prize Court. If that was dangerous or not practical, the prize ship could be sunk after 'due provision for the safety of passengers and crew, and for the preservation of the ship's papers.'
