Using Three Subs As One Unit
The Grayback returned to Pearl Harbor and was prepared for yet another mission in the Pacific on September 12th, 1943. This was her eighth during the conflict. Commander John Anderson Moore was the new person in charge of the sub. Two weeks after it came back to Pearl Harbor, it left for Midway Atoll with the U.S.S. Shad. The two of them were also joined by the Cero. Collectively, this trio was called a “wolfpack.” The method of combining these subs as joint attack forces had been successful with German U-boats, but this was the first time the tactic was used by the U.S. Navy.
