Communications Intelligence Summary, 26
General.-Traffic volume normal. All circuits heard well except for Tokyo-Takao circuit which faded early.
Traffic picture about the same as for
the past week. Intra-fleet traffic still very heavy and Tokyo Bureaus still dispatching AlNavs. The Tokyo
Intelligence and Direction Finder plotting
units addressed a succession of urgent dispatches to the major commands and to the CinC. Second and
Third Fleets in particular. The only
MAM schedule was NR15 which was first broadcast on the twenty- fifth. Takao and
Bako originated more traffic today than usual, it was addressed to Third Fleet mostly but the CinC.
Second Fleet and the China Fleets came
in for their share. Tokyo radio is working the ISIZU (flagship South China) SAMA and CAMRANH Bay radio stations
directly Takao is also working ITSUBA
Combined Fleet.-Cruiser Division Seven today began receiving traffic
via SAMA, indicating the arrival of
that unit in HAINAN waters. While no indications
were seen that Destroyer Squadron Three also arrived it is probable that this unit is still in company
with Cruiser Division Seven and is also
present at Hainan. The Takao, former flagship of the Second Fleet became active in the traffic today
being associated with the Second and
Third Fleets. The tanker HAYATOMO appeared in several of CinC. Second Fleet's dispatches today as well
as the SOYO MARU. No movement is
evident yet of any of the flags of the newly formed force. The traffic between Second, Third, Fourth
Fleets and the Combined Air Force still
continues at its high level.
Fourth Fleet.-No change in Truk location. CinC. held extensive communication with Saipan forces as well as
Palao forces. The KATORI and CinC.
Submarine Fleet appear to be at or near Chichijima.
Fifth Fleet.-The CinC. Fifth Fleet was included in some of the dispatches of the Second Fleet and is
associated with the new Task Force.
Submarines.-As noted above Commander Submarine Force is in Chichijima area. The Submarine Squadron NETE5's location
is somewhat uncertain today due to one
dispatch being routed to MAIZURU. The routing of this dispatch is doubted because of the indication
of her arrival at Takao yesterday and
her previous association with Cruiser Division Seven.
China.-Two Marus of the Third Fleet left Bako for Sama today.
Third Fleet.-Active as above but no indication of large scale movement from the Sasebo area.
