SE of Rokugo Zaki, NE of Noto Peninsula. At 0310, departs Nanao-Hoku Bay. Early in the morning, a Maizuru-based Aichi E13A1 "Jake" reconnaissance floatplane of the 901st NAG fitted with a magnetic anomaly detector (MAD) device detects a submerged submarine and attacks it with a 250-kg depth-charge. CD-26 and CD-22, enroute from Maizuru to Nanao Bay, are directed to the same area and attack the target at 0735. CD-22 drops 46 depth charges.

 Some sources indicate that CD-112 was in the escort not CD-26.
 MANJU MARU was sunk by aircraft in the same location on 20 Jan '45.
 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.
 Some sources indicate that W-15 was part of the escort of MOTA-40, but others do not.
 The target may have been the wreck of USS BONEFISH (SS-223) sunk in that area earlier.
 In 1945, the U. S. Army Air Force launched a five-phased campaign known as “Operation Starvation” to mine Japan’s home waters. The USAAF used 80 to 100 B-29 “Super Fortress” heavy bombers of the 21st Bomber Command based at Tinian in the Marianas. B-29s could carry seven 2,000 lb. or twelve 1,000 lb. mines.
Beginning on 27 March 1945 and continuing until 5 August 1945, B-29s flew 1,529 nighttime radar sorties and laid 4,900 magnetic, 3,500 acoustic, 2,900 pressure and 700 low-frequency mines for a total of more than 12,000 mines laid in Japanese waters. These mines sank 294 ships, damaged 137 beyond repair and damaged another 239 that could be repaired. The total was 1, 250,000 tons sunk or damaged or about 75 percent of Japanese shipping available in March 1945. Only 15 B-29s were lost during the mining campaign.
Postwar, removal of these mines posed a major challenge for the Allied Occupation Forces. They pressed 269 Japanese ships of various types into mine sweeping service to augment their own efforts.
Thanks go to Bill Somerville for info on CD-26's movements in late Aug '44 and to John Whitman for info on intercepted messages.
Thanks also go to Gilbert Casse of France, and John Whitman for info on HAKUSHIKA MARU in Rev 3 and 4.
