After the battle, ITSUKUSHIMA and NIPPO MARUs are ordered to return to Brunei.

27 October 1944:
Balabac Strait, W of Palawan Passage. At about 0248, LtCdr John M. Hyde's (USNA ’34) USS BERGALL (SS-320), on patrol near Dangerous Ground, makes SJ radar contact on four targets at 21,000 yards range. Hyde begins tracking on the surface. When the contacts became visible they are identified as large oilers accompanied by one large and one small escort.

At 0336 (H), Hyde sets up and fires six torpedoes at the targets. At 0339, ITSUKUSHIMA MARU is hit by one torpedo. At 0345, the second oiler in line, NIPPO MARU with a cargo of 13,000-ton of oil, is hit and sinks at about 0510 at 07-02N, 116-42E taking down four of her crew. ITSUKUSHIMA MARU remains afloat, but goes dead in the water and begins drifting between Sunken Barrier Shoals and the coast of Borneo in water so shallow USS BERGALL can not dive. The escorts counter-attack and drop 14 depth charges, but USS BERGALL clears the area on surface.

2 November 1944:
At 0854 (JST) the codebreakers intercept a message from SHIGURE that reads "---- Captain and 66 men at Kudat will be picked up by the Shigure. Expect arrive Brunei about _____ on the 2nd."

10 December 1944:
Removed from the Navy List.

September 1945:
A wreck is discovered by occupying Australian forces aground off Kudat. Based on descriptions provided it appears to be of ITSUKUSHIMA MARU.

26 April 1954:
A wreck appearing to be ITSUKUSHIMA MARU is towed into Hong Kong and is presumably scrapped.


Authors' Notes:
[1] Available Japanese records are unclear. It is possible ITSUKUSHIMA MARU was part of convoy HI-02.

[2] The attack coincides with that reported by LtCdr (later Vice Admiral) Veron Lowrence's USS KINGFISH (SS-234) that counted six depth charges, but was undamaged. The episode illustrated how the escorts' emotional attitude towards attack often preempted more sensible defensive measures. In this instance, no ships were sunk in the unescorted convoy, but such unwise tactics sometimes ended in disaster for the Japanese.

[3] This suggests that ship had been detached from the convoy.

[4] Japanese records are unclear. Convoy HI-23 departed 1 December and consisted of oilers OMUROSAN, ICHIU and ASASHIO MARUs and two other ships escorted by NAMIKAZE. It was at Takao 5 Dec '43. It is possible the ITSUKUSHIMA MARU joined this convoy at Takao. Oiler RYUEI MARU and passenger cargo ships AKI and NOSHIRO MARUs are also in the convoy, though in which part is not clear. The first echelon stopped at St Jacques enroute, but it is unclear if the second echelon did. A three-day difference separated their arrival times at Singapore.

[5] Somes sources credit AWAJI's sinking to Haskins' USS GUITARRO (SS-363).

[6] USN radio-intelligence intercepts and decodes the signal. They conclude it indicates a possible sortie by Kurita's fleet from the Singapore area.

Thanks for assistance goes to Allan Alsleben of Oregon, Gilbert Casse of France and Erich Muehlthaler of Germany.
