My 8495. The following message sent to Opnav quoted for your information and is to be maintained highly secret. Forward 8495 and this message to Paris for information of Admiral Benson. Six enemy submarines are now known to have arrived in the area referred to. None of them have left it and none are coming to that area from home ports. There has been no confirmed report of an attack by submarine or any vessel in any area for forty-eight hours. Admiralty will not use the thirty destroyers for offensive action against submarines but are employing a small number of destroyers fitted with hydrophones which will be succeeded later by submarines for hunting purposes and after[w]ards by the trawlers all equipped with hydrophones.
