[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.
