Removed from the Navy List.

Authors' Note:
[1] According to "Kaibokan Senki" (Battle History of Kaibokan Escorts), compiled by the former personnel of IJN escorts, LtCdr Ota Yoshio may have been a a predecessor CO to LtCdr Kanazawa, but if so, the date is unknown. [2] Exactly why so few of USS BARB's torpedoes failed to hit such a perfect overlapping target remains a mystery. Perhaps the torpedoes were defective, a problem the U. S. Navy never got quite right during, and even after the war. Rumors of more ships sunk persist, but they are not supported by facts.

Thanks for assistance go to Dr. Higuchi Tatsuhiro of Japan and to Mr Gilbert Casse of France. Thanks also go to Mr. Aki of Japan and Matthew Jones of Ohio for help in identifying kaibokan COs.
