The first entry in today’s Gray Book references the 13th Bomber Command sighting an unescorted enemy aircraft carrier in the Makassar Strait launch aircraft.
Makassar Strait is off of Borneo, south of the Philippines. Apparently, Borneo was one of the island skipped. I can find no other reference to this aircraft carrier. Would this not be a sitting duck?
I did see a reference to the Australians taking Borneo in May of 1945 in a battle they were criticized for as a waste of time and manpower.
