SITUATION REPORT: DECEMBER 12th-13th, 1941
For the first time in the war, Allied shipping losses to IJN subs has been greater than shipping losses to naval bombers. This may be due to the fact that most of the Allied shipping in the South China Sea has been evacuated or has already been sunk. At any rate the ASW/Sub war has really heated up:

Baby KB disappeared from our search screens off the north coast of Borneo a couple of days ago but their Claudes and Kates are still flying missions in the South China Sea. It makes me think that the CVLs are hiding in port at Brunei. Almost 40 Dutch and British level and torpedo bombers are staged into Tarakan to strike the port at Brunei....weather permitting.
