 ABDAFLOAT = American, British, Dutch and Australian Naval Command. In reality, a non-unified command.
 This marks the first known instance of an Allied attack on a Japanese hospital ship during the Pacific War.
 This IJN shared 5,794-ton collier (B/C-AC) YASUKUNI MARU was not IJN Sub Tender YASUKUNI MARU.
 The absence of damage to the larger ships in the convoy suggests they may have detached for Kirun (Keelung) before the attack with only the slower escorts and cripples left behind.
Thanks go to the late John Whitman and also Don Kehn, Jr. and Matt Jones of USA and Gilbert Casse of France.
