USS Grayback (Cdr. J.A. Moore) is often credited with the sinking of the Japanese transport ship Ceylon Maru (4905 GRT) in the East China Sea in position 31°50'N, 127°45'E.

We (Administrators U-boat.net Allied warships section) consider this attack questionable as it is way off Graybacks last known position and the position of her loss. We consider it more likely that the loss of Ceylon Maru was due to a drifting mine. No American submarines were operating in the area of Ceylon Maru's loss at the time.
