 On 8 Sep ’43, after the surrender of Italy, CONTE VERDE was scuttled by her Italian crew in the Whangpoo River, Shanghai. From 1943-44, the Japanese carried out several salvage attempts. CONTE VERDE was intended for conversion to an escort aircraft carrier, but on 8 Aug ‘44, a B-24 bomber sank her in the Whangpoo River for a second time. In Dec ‘44, the hulk was refloated. She was later repaired enabling her to steam by own power. After hitting a mine enroute to Japan, she was towed to Maizuru where she was bombed on 25 Jul ’45 and beached in Nakata Bay, N of Higashi, Maizuru. On 13 Jun ‘49, the wreck was refloated and began scrapping.
 Sources vary as to the date and place where KOTOBUKI MARU hit a mine.
Thanks for assistance go to Dr. Higuchi Tatsuhiro of Japan. Thanks also go to Mr. Aki of Japan and Matthew Jones of Ohio for help in identifying kaibokan COs and to Gilbert Casse of France.
