A Mystery
Grampus and Grayback both departed Brisbane in February 1943. This was her 6th war patrol, one that she never returned from. Japanese seaplanes sunk a sub on February 18th in Grampus’ area of patrol, but the Grayback reported seeing the ship in that same area a few weeks after. The ship’s disappearance remains a mystery to this day.
