Outstanding stuff Donner, thanks for posting it. Would love to read more. I did a google but could find no info on where to obtain a copy. I'm always on the lookout for info and accounts from the Japanese side, which are not easy to find. A book like Silent Victory gives great detail from the US side, would be great to have the other side too (like in Fluckey's book, where he often gives info from the Japanese perspective on the targets he attacked)
However, while googling your thing I came across this, about the sinking of Arisan Maru. This was convoy MA-TA-30 (Manilla-Takao?) with 12 marus and 5 escorts.
