(VII) It is believed, but not confirmed that the two aircraft
carriers from which the attack against HAWAII was launched were
the SORYU and OIUKAKU. They normally carry: SORYU, 12 fighters,
12 torpedo bombers and 18 dive bombers. OIUKAKU, 12 fighters
and 36 torpedo bombers and/or dive bombers. The attack therefore
probably did not exceed this scale. The torpedo bombers can carry
torpedoes or bombs. Air attacks on MANILA could have been made
either from FORMOSA or CANTON, more probably the former. Air
attacks on SINGAPORE will most probably have been delivered by
aircraft based on SOCTRANG.
(VIII) The Japanese occupation of THAILAND will, subject to
their being able to ship the commodities to JAPAN, assure the
supply of some 48,000 tons of rubber per annum and valuable supplies
of tin from the provinces South of the KRA Isthmus. This rubber
from THAILAND will, together with that from INDO-CHINA, provide
JAPAN with all the supplies she needs and allow for some export
to FRANCE or GERMANY. The quantity of tin available may be limited
by immobilisation of mining machinery. Small but useful quantities
of wolfram and zinc are also available. From the Northern provinces,
JAPAN will have access to substantial supplies of rice which
will provide her with a margin of safety, and also useful supplies
of hides. Prior to occupation JAPAN obtained from THAILAND all
the rice and hides she asked for, most of the rubber but less
than 1/3 of the tin.
