Editor's Note 1 - TF 38's aircraft scored bomb hits on Jingei that caused her to settle to the bottom in shallow water on nearly even keel and trim with slight starboard list with both ends submerged and only upper works, the two stacks and bridge standing above water. The precise position before salvaged post-war was 12 miles WSW of Ie Shima, 28 miles NNW of Naha, per Bob Hackett who had an old map of Okinawa from when he was stationed there, as related on on 2 July 2004. The 1952 salvage severed the fore-section forward of the bridge which was dismantled in-situ and refloated the main section for scrapping. - (Tully)
