The Grayback embarked on a combat patrol on January 28th, 1944, from Pearl Harbor. It was the sub’s tenth and final mission, as the Grayback was later posted, the submarine as being missing in late March 1944. However, a message was sent back to base before its disappearance.

Before its disappearance, the message sent by the Grayback stated that it had sunk two Japanese freighters and hit another two. However, the submarine had also caused severe damage to more Japanese freighters, which left the sub with only two torpedoes.
