Sometimes however queries were raised and I was wont to answer somewhat as follows:—
"I will explain the viewpoint of the High Command, which gave this order, by reference to the following event": I then mentioned the example of the Type VII boat in the Bay of Biscay together with the explanation and viewpoint expressed to me by Commander in Chief U-boats' staff. I then went on to say, "Gentlemen, you must yourselves decide what is compatible with own consciences. The safety of your own boat must always remain your prime consideration."
Since the introduction of total underwater war ("Schnorchel"), I have in this connection in various ways further stated that commanding officers were in a much easier position in this respect since they had no occasion to surface and that the order was therefore illusory for them. They had to keep clear of everything which was not worth the firing of a torpedo.
I also remember that many commanding officers after the order of September 1942 had been read said, "That is quite clear and unequivocal however hard it may be". Had this order been given to me as a commanding officer I would have taken note of it in silence but in practice would always have been able with a clear conscience not to carry it out since I consider I would endanger my own boat by acting in this way, (i.e., by shooting at life-boats).
If therefore U-boat commanding officers state that they had received from me the order to destroy life-boats, this does not correspond with the facts, but they received from me quite insufficiently clearly expressed instructions from the High Command together with my personal views thereon.
Before the order of September 1942 was issued I never discussed this difficult question at a commanding officers' conference and the subject of conduct towards survivors was never broached.
B. Conduct Towards Neutral and Hospital Ships
On this matter, which I treated together with what has gone before, I gave commanding officers the following directions:
There was an express order of the High Command, and Commander in Chief U-boats was adamant on this point and would relentlessly pursue the breach of it by court martial (i.e., he insisted on the order being strictly obeyed), that no neutral or Red Cross ship might be molested even if the enemy misused neutral flags or the Red Cross.
The political results of sinking a neutral were much more serious than would have been the usefulness of the tonnage sunk.
