“16. That Oberleutnant Lemp then showed me a declaration under oath according to which I had to bind myself to mention nothing concerning the incidents of 3 September 1939 on board the U-30.
“17. That this declaration under oath had approximately the following wording:
“ ‘I, the undersigned, swear hereby that I shall shroud in secrecy all happenings of 3 September 1939 on board the U-30, regardless whether foe or friend, and that I shall erase from my memory all happenings of this day.’
“18. That I have signed this declaration under oath, which was drawn up by the commandant in his own handwriting, with my left hand very illegibly.
“19. That later on in Iceland when I heard about the sinking of the Athenia the idea came into my mind that the U-30 on the 3 September 1939 might have sunk the Athenia, especially since the captain caused me to sign the above-mentioned declaration.
