On January 28, 1944, Grayback was sent out from Pearl Harbor on a combat patrol mission. At the time, the sub was going on its tenth such journey and sad to say, it was the last. A few weeks before it went off the radar, it sent a couple of victory messages back to its base, noting the demolishing of two rival subs, the Japanese freighters Toshin Maru and Taikei Maru and a few others. This message was transmitted on February 24.

The following day, February 25, the crew sent another victory message noting they had destroyed the liner Asama Maru – a Japanese sub that was used in military battle as a troop carrier. They also sunk the Nanpo Maru tanker. However, since the last report, there were no more victory releases as the sub reported they had to move to Midway Atoll in the North Pacific to re-supply as they only had two torpedoes remaining.
