Communication Intelligence Summary, 12
General.-Traffic volume normal for past two days with receiving condition about average. The general
character of the traffic has been administrative
With most of it being between shore logistic and technical activities. The D. F. net was active today with very
little activity shown yesterday.
Intercept operators have commented adversely on the major shore network which comprises all of the major naval activities in the EMPIRE. Traffic has been
moving slowly over this circuit. The
reason is the non-cooperation of the operators and the definite lack of control exercised by TOKYO
radio stations. TOKYO Intelligence is
still sending messages to the major commands but the remainder of TOKYO traffic has been mostly from the technical
Combined Fleet.-The Fleets remain relatively inactive in the KURE area The association of BATDIV 3 with the Fourth
Fleet and several Mandates stations is
born out by a D. F. position on the flagship of BATDIV 3 which places him about halfway between
CHICHIJIMA and MARCUS Island. Their
position was obtained on the 4th when this unit was not yet identified. No subsequent bearings have been
obtained. Also associated with this
BATDIV are a Submarine Squadron and possibly CARDIV 4 although the association of this CARDIV (Lately
returned from TAKAO) is not positive.
The Third Fleet remains at SASEBO with the only activity exhibited in the Base Forces. Page 67
Air.-CARDIV 3 returned to KURE from TAKAO as reported by CAVITE. Most
of air activity confined to dispatches
between carrier and shore establishments.
Fifth Fleet.-Nothing to report.
Fourth Fleet.-The Defense Forces of the Mandates fairly active. The volume of construction traffic has definitely
fallen off. The Commander Submarine
Force is still adding JALUIT and today COMSUBRON 2 addressed a message there. AIRRON 24 sent a movement
report but no indication of the direction.
Communication exercises were held by JALUIT and several stations in that area. YOKOHAMA Air Corps was
addressed at RUOTTO.
