Biak, New Guinea. Alerted the previous day by a PBY "Catalina" flying boat to the movement of a Japanese convoy towards Manado, Celebes, Col. Chester A. Coltharp's 345th Bomb Group's 499th, 500th and 501st Bomb Squadrons' North American B-25 "Mitchell" medium bombers take off from Biak and stage through Noemfoor to attack the convoy.

The 345th's planes search in vain for the convoy, then head for Lahbeh (Lembeh) Strait, NW Celebes. Near the S end of the strait, they find ITSUKUSHIMA sitting broadside in the narrow passage. Two of the 499th's B-25's attack the minelayer and score a near miss with a 500-lb bomb. ITSUKUSHIMA's aft section floods and she loses all power.

At Bitung, according to GHB telegram order No. 55, minelayer WAKATAKA is ordered to provide assistance to minelayer ITSUKUSHIMA damaged (1215-1230) by North American B-25s of 345th BG while at anchor in Lembeh Strait.

2 September 1944:
Lahbeh Strait, Celebes. Thirteen B-25s of the 345th BG attack Japanese installations along the strait. Six of the B-25s attack Lambeh Town and ITSUKUSHIMA. The minelayer throws up an intense barrage of AA fire that shoots down 2nd Lt Lloyd B. Bardwell's B-25D nicknamed the "Mexican Spitfire." ITSUKUSHIMA's AA fire also damages two other B-25's that later crash-land at Middleburg Island, NEI.

Bardwell ditches in the water about 7 miles from Lahbeh Island. Several survivors are seen. 2nd Lt Allan W. Lay flies top cover in B-25D "Hell's Fire". Soon, three Mitsubishi A6M "Zeke" fighters arrive. Two attack Lay's B-25 and the third strafes Bardwell's crew in the water. The Zekes shoot down Hell's Fire. The "Mexican Spitfire's" crew is never seen again.

At 1110, departs Bitung escorted by WAKATAKA, following a route through Bangka Strait along N-coast of Minahasa Peninsula, N Celebes.

Deck ---- damaged; breaches of diameter about 5 meters; no---. Killed: 30 men ----. Seriously wounded: about 50 men.”

As a result of this I am towing ITSUKUSHIMA. Will leave Pagalungian at 040530. Proceeding to Dangulan (00-30N, 120-00E).”

17 October 1944:
Java Sea. E of Bawean Island. Lookouts aboard Ltz I Hendrikus A. W. Goossens' Dutch submarine HNMS ZWAARDVISCH (ex-British HMS TALENT) spot a minelayer flanked by escorts, probably heading for Surabaya. Goossens sights a tugboat a mile and half away. It is dragging a towline that leads to the minelayer. He sets up to attack the minelayer with a spread of five torpedoes, but an opportunity presents itself to hit an escort as well. Goossens fires three torpedoes at ITSUKUSHIMA and two at the escort.

ITSUKUSHIMA is hit by one torpedo and sinks at 05-23S, 113-48E. Captain Oishi and an unknown number of crewmen survive the sinking. Escorting WAKATAKA is also hit in the bow and damaged, possibly by a dud torpedo. [1]

Subchaser CH-26 carries out a determined counterattack, dropping a pattern of 18 depth charges. After several hours, Goossens comes to periscope depth, but is attacked again, this time with 16 depth charges. The sea floor is only 195 feet deep, but ZWAARDVISCH escapes.

22 October 1944:
At 1805, USN codebreakers intercept a message that says: “At 1058, 17th, Subchaser No. 2 in command of Subchaser No. 26 detected and attacked the enemy submarine which attacked ITSUKUSHIMA and WAKATAKA with torpedoes. Subchasers sank the submarine definitely at 1337, 18th in position 05-22 S., 113-55 E.”

Authors' Notes:
[1] On 15 Dec 2002, dive charter vessel MV EMPRESS of Singapore, using side-scan sonar, discovered the wreck of ITSUKUSHIMA in 184 ft/56 m of water, well to the NE of Bawean Island in the Java Sea. One of the divers aboard at the time, photojournalist Kevin Denlay, who has since revisited the wreck site several times, reports:

"The wreck lies in two sections, cleanly severed where ZWAARDVISCH's torpedo struck aft. The forward section rests 350 to 400 yds/meters from the stern. Disappointingly, the much larger forward section is upside down from the bow stem to the break where the three prop shafts begin to exit the hull. No upper-works or superstructure can be seen. The small stern section sits upright and is relatively intact. The deck is deteriorated with the doors on the two outer mine laying ‘wings’ closed and in place. The doors across the stern are missing. No 5.5-inch guns can be seen on the aft section, but one gun sits upright on the seabed about 49ft/15m from the break. ITSUKUSHIMA's outer port propeller is clearly visible under the stern, still on the shaft and connected to the hull by the ‘V’ support - but now embedded halfway into the seabed."

Special thanks for assistance in developing this TROM go to Jean-Francois Masson of Canada, Berend van der Wal of Netherlands, Allan Alsleben of Oregon and Kevin Denlay of Australia.

Thanks also go to John Whitman for info on USN intercepts of IJN messages, to Matt Jones for additional CO info in Rev 3, and to Mr. Gilbert Casse of France for general assistance.
