Docking in Australia
Enemy weapons damaged a hatch on Grayback’s hull, and as such, there was a leakage that caused her to dock on Brisbane port in Australia. The sub’s next patrol in February 1943 saw no successful attacks due to a malfunctioning radar and other newly installed fittings. These spontaneous technical malfunctions pushed the crew’s resourcefulness to new limits. Luckily enough, the Grayback pushed through to her seventh tour, which began in April 1943.

Sinking the Enemy Ships
This cruise saw Grayback yielding much success as on tour, she hit Yodogawa Maru, an enemy merchant ship with two torpedoes. It eventually sank. A few days down the line, she managed yet again to destroy another enemy ship with a single torpedo. By the following day, another cargo ship was sunk by Grayback, the England Maru, in addition to two others. After these many victories, she set sail back to Pearl Harbor then to San Francisco, California, where she would undergo a refitting process.
