Sealion's recorded attack and memorialized torpedoes

Four of Sealion's torpedoes carried the names of men killed when the first submarine of that name was bombed three years earlier. A CBS war correspondent had left recording equipment aboard, and the crew placed its microphone beside the conning-tower intercom during the attack. This recording and another made during an attack on a Japanese oiler were preserved by the Naval Underwater Sound Laboratory. Their status as the only surviving recordings of Second World War submarine attacks remains qualified: other navies may have made recordings, and the survival of any others is uncertain.
