6138. My 4640. Owing to lack of success in operations against submarines in area west of Brest Admiralty proposes to adopt Department’s suggestion in cable 1189 and send submarines to operate in this area. It would greatly assist chances of successful offensive if O-boats were sent to this side to operate either in this area or wherever chances of success were most likely. 130403 6138
