 Sources conflict as to the date of HMS THRACIAN's scuttling. Most British sources say she was intentionally grounded on 16 Dec '41, but others put this date at 24 Dec '41.
 HMS TAITAM and HMS WAGLAN are later completed by the Japanese and registered in the IJN as minesweepers W-101 and W-102.
 PB-101 is, of course, an Allied designation. The original IJN designation was "101-go Shokaitei" or No. 101 Patrol Boat.
 The ship's bell survived and is now held by the "Blue Boar" Public House at Poole, Dorset, England.
An account exists that PB-101 was used as a radar trials ship for the successful "Long Lance" Type 95 torpedoes, in which the Japanese installed their latest experimental gear including water-cooled S-band magnetrons, but the story is questionable.
Thanks to Mr. Gilbert Casse of France for assistance with Revision 6 and to Matthew Jones of Mississippi, USA for CO information.
