Another torpedo just misses CD-40. HAKOZAKI MARU is torn apart by internal explosions as her cargo of gasoline, shells and torpedoes ignites and blows off her stern. She quickly sinks, but her forward section stays afloat blazing until finally sinking at 0320.

The combination of fire, explosions and 5 degrees centigrade water means that almost all aboard perish. 928 passengers, 51 gunners and 139 crewmen, a total of 1,118 are KIA. The torpedo strike on TATSUHARU MARU kills 149 military personnel, but the ship remains afloat and later makes Shanghai.

Yellow Sea. LtCdr (later MOH/Captain) George L. Street III’s (USNA ’37)USS TIRANTE (SS-420), alerted by an “Ultra” signal, intercepts convoy TAMO-53 enroute from Shanghai to Japan. Street fires three Mark 18-2 electric torpedoes at each of two targets at 36-50N,123-55E. One spread misses, but the other hits NIKKO MARU in the bow and engine room. She and sinks taking down 563 passengers, 14 gunners, 16 guard force soldiers, two signalers and 73 crewmen.

The escorts counter-attack USS TIRANTE. Street fires a Mark-27 "Cutie" acoustic homing torpedo that damages CD-102. USS TIRANTE’s crew hears "breaking-up noises," but the kaibokan does not sink.

Authors' Note:
[1] Allied occupation forces were responsible for the return of six million Japanese military personnel and civilians from Japan's defunct far-flung Empire. In addition, there were over a million Korean and about 40,000 Chinese prisoners and conscript laborers and approximately 7,000 Formosans and 15,000 Ryukyu Islanders to be repatriated.

Some Allied and many former IJN warships, from aircraft carriers to kaibokan, were used to facilitate the enormous repatriation effort. Japanese vessels and crews were used to the fullest extent possible to conserve Allied manpower and accelerate demobilization. Each ex-IJN ship first had to be demilitarized; guns removed or, in the case of large warships, barrels severed, ammunition landed, and radar and catapults removed, if fitted. Repatriation of the Chinese on Japanese ships began early in October from Hakata, but U.S. guard detachments had to be placed on many ships to prevent disorder because the Japanese crews could not control the returnees.

Japanese-run repatriation centers were established at Kagoshima, Hario near Sasebo, and Hakata near Fukuoka. Other reception centers were established and operated at Maizuru, Shimonoseki, Sasebo, Senzaki, Kure, Uraga, Yokohama, Moji and Hakodate. Allied line and medical personnel supervised the centers. Incoming Japanese were sprayed with DDT, examined and inoculated for typhus and smallpox, provided with food, and transported to his final destination in Japan.

Thanks for assistance goes Mr. Iwasaki Yutaka of Japan and Mr. Gilbert Casse of France.
