Twelve Tachikawa Ki-36 "Ida" Army bombers of the 45th Sentai based at Canton escorted by nine Ki-27 "Nate" fighters also attack Kai Tak airport on Kowloon. The Ida's bomb from low level, while the Nates strafe.

Authors' Note:
[1] Sources conflict as to the date of THRACIAN's scuttling. Most British sources say she was intentionally grounded on 16 Dec '41, but others put this date at 24 Dec '41.

[2] HMS TAITAM and WAGLAN are later completed by the Japanese and registered in the IJN as minesweepers W-101 and W-102.

[3] PB-101 is, of course, an Allied designation. The original IJN designation was "101-go Shokaitei" or No. 101 Patrol Boat.

An account exists that PB-101 was used as a radar trials ship, in which the Japanese installed all their latest experimental gear including water-cooled S-band magnetrons, but the story is questionable.
