2 page memo with only the 2nd page being the actual information.
White boxes used
to block out legibility in the heading –
who it is addressed to?

It begins:

COMTAIWANDEFCOM/US ( is this Taiwan defense?)
COMNAVFORJAPAN ( command navy Japan?)

On 2 Aug DRV vessel T142 passed. Its ship’s log was as follows:
0925 join 135 at IGRU
1115 lead 135 into Hom Me
1245 join 165 at Hom Me
1300 135 and T146-142 possibly departed
1525 saw the 135 …attack the enemy.
1630 we are ordered to turn around and return to concentrate at IGRU
and communicate with 165.

Agreed... not much to this memo.

A lot of bits and pieces but the jist is clear. The aim of SIGINT isn't just to intercept human communications but also pure electronic ones such as radar. Anything which could be of tactical advantage!
