“A: ‘On general principles, the U.S. submarines did not rescue enemy survivors if undue additional hazard to the submarine resulted or the submarine would thereby be prevented from accomplishing its further mission. U.S. submarines were limited in rescue measures by small passenger-carrying facilities combined with the known desperate and suicidal character of the enemy. Therefore, it was unsafe to pick up many survivors. Frequently survivors were given rubber boats and/or provisions. Almost invariably survivors did not come aboard the submarine voluntarily, and it was necessary to take them prisoner by force.’

“14. Q: ‘If such an order or principle did not exist, did the U.S. submarine actually carry out rescue measures in the above-mentioned cases?’

“A: ‘In numerous cases enemy survivors were rescued by U.S. submarines.’

“15. Q: ‘In answering the above question, does the expression “merchantmen” mean any other kind of ships than those which were not warships?’

“A: ‘No. By “merchantmen” I mean all types of ships which were not combatant ships. Used in this sense, it includes fishing boats, et cetera.’

“16. Q: ‘If yes, what kind of ships?’

“A: ‘The last answer covers this question.’

“17. Q: ‘Has any order of the U.S. naval authorities mentioned in the above questionnaire concerning the tactics of U.S. submarines toward Japanese merchantmen been based on the grounds of reprisal? If yes, what orders?’

“A: ‘The unrestricted submarine and air warfare ordered on 7 December 1941 resulted from the recognition of Japanese tactics revealed on that date. No further orders to U.S. submarines concerning tactics toward Japanese merchantmen throughout the war were based on reprisal, although specific instances of Japanese submarines committing atrocities toward U.S. merchant marine survivors became known and would have justified such a course.’

“18. Q: ‘Has this order or have these orders of the Japanese Government been announced as reprisals?’
