[146] COMMUNICATION INTELLIGENCE SUMMARY, 9
November, 1941
General. Traffic volume heavy for Sunday. Receiving conditions fair but
heavy static caused numerous garbles
and fragmentary messages. Navy Minister
sent several messages of general address including one to all First and Second Class Naval Stations.
Practically all of the general messages
carried SAMA as an information address. Carrier Division Three arrived at Takao and there are indications
that Carrier Division Four will return
to Sasebo from Takao. The Flagship of Carrier Divisions is AKAGI and is in Sasebo area. Some tactical
traffic today shows units of Combined
Fleet still operating. The associations of Batdiv Three and Mandate addresses, especially Saipan may
indicate operations of that unit in the
Mariannas. The JINGEI was communicating with SAMA, HAINAN today. The Chief of Staff of the French-Indo
China Force is in Tokyo.
One message today addressed to CinC. Combined Fleet was routed to MAIZURU for delivery but this is believed a
communication error. The Third Fleet
appears to be still in Sasebo area but it was noted that considerable traffic passed between Hainan,
Taiwan addresses and the Third Fleet.
The Fifth Fleet is still being organized with no indications yet that it has assembled. The Eighteenth Air Corps at
Saipan originated much traffic to
Yokosuka Air Corps.
