My second remark concerns the question as to what extent a military commander may be held responsible for the accuracy of legal reasonings which he does not indulge in himself, but which are delivered to him by the leading experts of his country, who after all are not just small-town lawyers. In addition, the Commander of U-boats had only tactical tasks and his staff contained only a few officers, none of whom was qualified to examine questions of international law of the import mentioned here. He therefore had to rely on the fact that the orders issued by the Naval Operations Staff were examined as to their legality and were in order. That is probably handled in a like manner in every navy in the world. A professional seaman is not competent for legal questions; with this reason the Tribunal cut off a remark by Admiral Dönitz about a legal question. This condition must, however, be considered in applying the principle which the German Supreme Court, during the war crimes trials after the first World War, formulated in this regard, and I quote: “The culprit must be conscious of the violation of international law by his actions.”
This appears to me to be equally just, as I should deem it to be incompatible with the demands of justice if soldiers were charged with a criminal responsibility in deciding legal questions which could not be settled at international conferences and are hotly disputed among the experts themselves.
In this connection I should like to mention that the London Pact of 1930 did not from the Root Resolution of 1922 adopt the principle of criminal prosecution for violations of the rules of U-boat warfare. The five naval powers participating in this conference apparently came to the conclusion that the problems of naval warfare cannot be solved by means of penal law. And this fact applies fully today, too.
I am now coming to the second basic charge of the Prosecution—intentional killing of shipwrecked crews. It is directed only against Admiral Dönitz, not Admiral Raeder. The legal basis for the treatment of shipwrecked crews for those ships which are entitled to the protection of the London Agreement of 1936 is laid down in the agreement itself. There it says that, before the sinking, crews and passengers must be brought to safety. This was done by the German side, and the difference of opinion with the Prosecution concerns only the question already dealt with, namely, which ships were entitled to protection under the agreement and which were not.
In the case of all ships not entitled to protection under the agreement, sinking should be considered a military combat action. The legal basis, therefore, with regard to the treatment of shipwrecked crews, in these cases is contained in the Hague Convention concerning the Application of the Principles of the Geneva Convention to Naval Warfare of 18 October 1907, although it was not ratified by Great Britain. According to this, both belligerents shall after each combat action make arrangements for the search for the shipwrecked, as far as military considerations allow this. Accordingly the German U-boats were also bound to assist the shipwrecked of steamers sunk without warning as long as by doing so, first, the boat would not be endangered and, secondly, the accomplishment of the military mission would not be prejudiced.
These principles are generally acknowledged. In this connection I am referring to the order of the British Admiralty, for example, and I quote: “No British ocean-going merchantman shall aid a ship attacked by a U-boat.”
I further refer to the affidavit of Admiral Rogge, according to which in two cases, personally witnessed by him, nothing was done by a British cruiser to rescue the shipwrecked, because U-boats were assumed to be nearby, once correctly so and once erroneously. A higher degree of self-endangering would appear to apply to U-boats as compared with other types of vessels because of their exceptional vulnerability.
As to the second exception to rescue duty, namely, prejudice to the military mission, the U-boat is also subject to special conditions. It has no room to take guests aboard. Its supply of food, water, and fuel is limited and any considerable expenditure will prejudice its combat mission. Furthermore, it is typical for the U-boat that the combat mission may call for an unobserved attack and therefore exclude rescue duty. In order also to present an opinion about the tactics of the opposite side, I quote from the statement of Admiral Nimitz:
“In general U.S. submarines did not rescue enemy survivors if it meant an unusual additional danger for the submarine or if the submarine was prevented from further carrying out its mission.”
In the light of these principles I will briefly deal with rescue measures by U-boats until the autumn of 1942. The basic order was issued by the Naval Operations Staff on 4 October 1939, and specified rescue whenever possible from the military standpoint. This was temporarily restricted by Standing War Order 154. This order, issued in December 1939, applied to the small number of submarines at that time operating immediately off the British coast. It may be seen from the order itself that every paragraph deals with combat in the presence of enemy escort and patrol forces. The last paragraph therefore also deals only with this aspect and serves the warranted purpose of protecting submarine commanders against the dangers to which, under the existing circumstances, they would in every case expose their boats by rescue measures. When after the Norwegian campaign the scene of activity of the submarines gradually shifted to the open Atlantic, this order became outdated, and it was finally canceled in the autumn of 1940. In the period that followed, the German submarine commanders carried out rescue measures whenever they could assume responsibility from the military standpoint. This is known to the Tribunal from numerous specific examples cited here, contained both in the statements of submarine commanders submitted here and in the war diaries. This situation was changed through Admiral Dönitz’s order of 17 September 1942, in which he forbade rescue measures on principle. The decisive sentences are:
