Authors’ Notes:
[1] A photo taken by TG 38.3 prior to attack on shipping off Busuanga Island clearly shows a 2TL tanker - almost certainly TAIEI MARU in the Tangat area, east of where the wreck of a large tanker was found. Nevertheless, uncertainty still surrounds the final fate of TAIEI MARU. Although most sources report the ship as sunk at Coron and a wreck of the right size has been found, doubts remain for some who claim the wreck is that of similar sized 1TL tanker OKIKAWA MARU. However, other sources claim OKIKAWA MARU was never part of the Taihi convoy and was, in fact, sunk earlier in Manila Bay.
