Details of Aircraft Losses by Date


Text Notes

06 Oct 1944:[1] A Liberator B.VI[1a] with the designation EV940 was homebased with Squadron 355 at Salbani Airfield, India[1b] (N22°36.75 E87°17.9):[2]

B-24 Flight path Uttaradit

At the Uttaradit Railyard, Sila At (N17°38.3 E100°06.0), the heavy bomber made a low level strafing run on locomotives. The plane was seen by another in the flight to have been hit by anti-aircraft fire and it eventually crashed at N17°25 E100°05, about 25km south of the railyard. Nine crewmembers were killed and two were taken prisoner.

  Umemoto comment:[5]

午後、8機で、同じくバンコク、チェンマイ間の鉄道攻撃に赴いた第355飛行隊、ハリスン曹長 のB24も、ゥッタラディト駅付近で、日本戦闘機1機の攻撃を受け、目標上空で被弾、目標から約8キ ロ離れた地点の森に墜落、爆発、射手のトンプスン軍曹だけが墜落から生き残り捕虜になった。このリ ベレーターと交戦したのも、当時、タイのドムアン飛行場にいた204戦隊の一式戦と思われるが、日 本側による詳細な記録は見あたらない。64戦隊の宮邊大尉は、雨季明け後、ドムアンに来襲した連合軍 機の邀撃には第1中隊の中村大尉らが指導したタイ空軍の一式戦も参加「敵機と堂々と渡り合った」と している。もしかすると、ハリスン曹長のB24を撃墜したのはタイ空軍機だったのかもしれない。

In the afternoon [of 06 October 1944], the 355th Squadron, Master Sergeant Harrison's B-24, went on a railroad attack between Bangkok and Chiang Mai with eight aircraft, was attacked by a Japanese fighter near Uttaradit Station and was hit by gunfire from the target area. A crash, explosion, and only Sergeant Thompson, a gunner, survived the crash in a forest about eight kilometers away and became a prisoner of war. It seems that the engagement with this Liberator was a flight from the 204th Sentai at Don Muang Airfield in Thailand at that time, but no detailed record by the Japanese side can be found. Captain Miyabe of the 64th Sentai also participated with the Royal Thai Air Force's fighters under the guidance of Captain Nakamura of the 1st Company during the attack of the Allied aircraft on Don Muang after the rainy season. Perhaps it was the Royal Thai Air Force that shot down Master Sergeant Harrison's B-24.

Observation about Umemoto's suggestion that the RTAF might have been involved: the aircraft was downed by ground-based machine gun fire, as witnessed by another aircraft in the flight. The IJAAF would not likely have bothered with assembling a report that didn't involve action on its part --- hence "no detailed record by the Japanese side can be found".

In this particular instance, it would appear that Umemoto incorrectly intermingled events surrounding the loss of three B-24s on this date. Two 159 Squadron aircraft targeting the railway line had been brought down by 204th Sentai Ki-43s and / or anti-aircraft fire (and / or possibly one or more RTAF aircraft as speculated by Umemoto); but these particular B-25s fall outside the scope of this website (see Steve Darke's Thai Air Accidents, page 2, entry for Serial Nos "BZ978 / W & BZ992 / E").

• Shores, 2005

Saturday, 07 October 1944

During the last minute of the previous day, 16 Liberators of 159 Squadron took off for a raid on the railway north of Bangkok at low level; they were joined by eight more bombers from 355 and 356 Squadrons. . . .

204th Sentai pilots claimed another Liberator near Bangkok, and yet another was claimed by AA crews. . . . One of these aircraft was a 355 Squadron machine, which was reported shot down over the target and which crashed in a wood eight kilometres from the railway target when attacked by a lone Ki-43.[6]

1.^ Dates recorded for the event are not consistent:

Royal Air Force Commands: Liberator EV940 (undated) records 06 Oct 1944.

Umemoto [梅本弘, ビルマ航空戦・上 [Air War in Burma, Vol 2] (Tokyo: Dai Nippon, 2002)], p 519, line 6, records the same.

USAF Serial Number Search Results records EV 940 (Consolidated No 64321) as lost 08 Oct 1944.

Shores appears to use 07 Oct 1944 [Shores, Christopher, Bloody Shambles, Vol Three (London: Grub Street, 2005), p 270 (see References below).

1a.^ Liberator B.VI was the RAF designation for Consolidated B-24Js delivered to the RAF under Lend-Lease (Liberator VI/VIII for RAF, website maintained by Joseph F. Baugher).

1b.^ Salbani, per, is now Salboni, per Google Earth.

Umemoto (ibid) incorrectly cites Digri Airfield as origin for the 355 Squadron: that field was its second location, but only starting in Jan 1946.

Orders of battle for both 01 Jul 1944 and 12 Dec 1944, covering the date of this event, locate the 355 Squadron (184 Wing), at Salbani, as a part of HQ, Air Command SEA, New Delhi, Eastern Air Command, New Delhi, Strategic Air Force, Calcutta, 231 Group [Shores, ibid, p 392].

2.^ Coordinates per Google Earth. Photo from Liberator B VI.

3.^ Extract from Google Maps; annotated with Microsoft Publisher.

The waypoint shown, Cheduba Island (N18°52 E93°29), is an assumption since a USAAF B-24 flying to bomb Kuang Luang Bridge on 21 Nov 1944 used Sagu Island (now Saku) on the east side of a channel from Cheduba, while an RAF Liberator B.VI which crashed near Nakhon Sawan on 29 May 1945 is recorded as having used Cheduba.
