In its judgment in the Dover Castle case in 1921, the German Reichsgericht held that the accused, the commander of a submarine from which a British hospital ship had been torpedoed, was in the circumstances of the case entitled to hold the opinion that the measures taken by the German authorities against foreign hospital ships were not contrary to international law but were legitimate reprisals. The accused had pleaded that in sinking the ship he had merely carried out an order of the German Admiralty, which, in the belief that the enemy utilized their hospital ships for military purposes in violation of the 1907 Hague Convention (X), issued a number of orders instructing the submarines to attack hospital ships as vessels of war.
