ENCOUNTER's Chief Engineer reports that repairs will take two hours. Surrounded and motionless with only one gun firing, Morgan orders his ship scuttled and her crew to abandon ship. At 1335, ENCOUNTER rolls over and sinks. Eight men are KIA and 121 rescued to become POWs.[3]

Lt Utsunomiya shadows destroyer POPE as she flees the engagement, making heavy black funnel smoke as she goes. At about 1540, POPE is attacked by dive-bombers from CHITOSE, MIZUHO and RYUJO. LtCdr (later Rear Admiral) Welford Charles Blinn's POPE is hit by bombs and comes to a halt. Her crew begins lowering boats and abandoning the ship. One man is KIA and 151 rescued to become POWs.

15 May 1945:
Indian Ocean, NE of Sabang. The HAGURO group is spotted by aircraft from Task Force 61's escort carrier SHAH. At 1330, the group observes a B-24 patrol bomber (probably from the RAF No. 222 Group) passing overhead at 07-02N, 97-02E; HAGURO opens fire from main guns with Type 3 AA rounds. Around 1541 the force is attacked by a flight of three Grumman TBF "Avenger" Mk. Is of No. 851 Sqn. from Force 61's escort carrier EMPEROR, claiming one 500-lb bomb hit and a near miss. Two "Avengers" receive flak damage; the cruiser is not damaged.

At 1330 Rear Admiral Sugiura receives a signal from the CO of the 10th Area Fleet, Vice Admiral Fukudome Shigeru (former CO of NAGATO), that aircraft have sighted a heavy cruiser and two destroyers S of Sabang Island, heading SE at 16 kts. Vice Admiral Hashimoto then orders a reversal of course.

After 1500 in position 07-10N, 96-24E, the HAGURO group sights the auxiliary supply ship KUROSHIO MARU No. 2 (ex-T.149) and CH-57, carrying evacuated troops from Nancowry Island in the Nicobars.

After 1700 HAGURO receives several sighting reports confirming that enemy cruisers and destroyers are heading towards Malacca Strait. Vice Admiral Hashimoto orders to proceed towards One Fathom Bank at 28 kts; later the speed is reduced to 24 kts for an ETA 0530 the following morning. KAMIKAZE's skipper is not informed about this decision.

Malacca Strait. At 2240, Captain (later Admiral Sir) Manley L. Power's 26th Destroyer Flotilla, who has anticipated Hashimoto's change in course, makes radar contact with the HAGURO group approaching from the north. The 26th's destroyers, making 28 kts, are four miles apart in line abreast formation and include Power's HMS SAUMAREZ, LtCdr D. H. R. Bromley's VERULAM, Cdr H. G. D. De Chair's VENUS, LtCdr A. J. R. White's VIRAGO and LtCdr L. W. L. Argles' VIGILANT.

16 May 1945:
At midnight, the range is 28,000 yds. HAGURO is in the lead with KAMIKAZE close behind. The 26th Flotilla reverses course to the south and slows to 12 kts. The destroyers, still in line abreast, are now arrayed in a semi-circle from the NW through the S to the E. At 0054, the HAGURO group, still unaware of the British, enters the semi-circle.

Alerted, the Japanese begin zigzagging, but remain on their southerly course and enter the center of the semi-circle. The 26th Flotilla increases speed and pursues. At 0105, the HAGURO group reverses course to the SE and the range drops to 6,000 yds.

Between 0114-0202, the 26th Flotilla attacks from all sides. HAGURO opens fire with main guns at 0218 and hits SAUMAREZ with an 8-in shell. All of the British destroyers claim hits with their torpedoes at ranges from 1,200 to 2,500 yds. HAGURO is hit by 3-4 Mk.IX torpedoes. The first hit at 0120 floods the forward generator room and ignites fuel drums carried as deck cargo around the fore turrets. She slows and takes on a 15-degree list to port. The forward magazines are flooded and the cruiser makes smoke. Most fuel drums carried on the afterdeck can be jettisoned.

At 0135, the second torpedo hit floods the port forward engine room and increases the list to 35 degrees so that most of the AA guns on that side are disabled. The cruiser goes dead in the water. Captain Ono Itaru (50), the XO, orders to flood the starboard engine rooms and to save the Emperor's portrait, preserved in the lower communications room, which is found to be already flooded. Vice Admiral Hashimoto, HAGURO's navigating officer LtCdr Ota Kazumichi (59) and several staff officers are killed on the bridge by destroyer gunfire, Captain Ono is wounded. Power failure disables the remaining main guns while a few 12.7-cm and 25-mm mounts on the starboard side continue to fire.

One (possibly two) torpedo hit forward causes an increasing bow trim. At 0232, HAGURO sinks bow first 55 miles WSW of Penang at 04-49N, 99-42E. 751 men are killed including Vice Admiral Hashimoto and Rear Admiral Sugiura (the latter last seen in the water). KAMIKAZE, although damaged, escapes to Penang.[6]

USN codebreakers intercept and decrypt a message with a call sign Ho-Ro-Ne-2, timed 0631, probably from KAMIKAZE, that reads: "Action Summary. At --- time in position 04-49N, 99-42E HAGURO and KAMIKAZE on course 150, speed 22 knots, encountered enemy task force made up of 2 (cruisers?) and 1 destroyer heading southward. Engagement range was between 3 and 6 kilometers. At ---- time HAGURO received a hit destroying ----- gun. ------. Damage incurred. Received 3 hits in 3 sections of the ship. 19 killed, 13 wounded."

17 May 1945:
Three E13A1 "Jake" floatplanes from Penang observe about 200 survivors in the water and drop life rafts and supplies. KAMIKAZE returns and rescues 320 men, 10 of them seriously injured (six dying later).

Rear Admiral Sugiura is promoted Vice Admiral, posthumously as of May 16.

20 June 1945:
Removed from the Navy List.

Authors' Notes:
[1] Mt. Niitaka, located in Formosa (now Taiwan), was the highest point in the Japanese Empire at the time.

[2] On 1 December 2002, a group of divers including the Australian diver/photo-journalist Kevin Denlay operating off MV EMPRESS out of Singapore, discover the wrecks of the cruisers DE RUYTER and JAVA off Bawean Island in the Java Sea at a depth of about 225 ft, using a side-scan sonar.

[3] On 21 February 2007, a group of divers operating from MV EMPRESS out of Singapore, including Australian photo-journalist Kevin Denlay, locate the wrecks of British heavy cruiser HMS EXETER and destroyer HMS ENCOUNTER in the Java Sea, 350 miles from Sunda Strait. EXETER lays on her starboard side in 60m/200ft of water. Her faithful consort ENCOUNTER rests about two miles away.

[4] In December 2008, the remains of USS POPE (DD-225) was located in the Java Sea in approx 105 feet/32 meters of water by owner/skipper Vidar Skoglie's dive vessel MV EMPRESS. The old destroyer appears to have been found earlier by Indonesian salvage divers and very little remains but a rusted skeleton.

[5] From early March to late April 1945 FRUMEL constantly confused HAGURO with the heavy cruiser ASHIGARA, operating in the same area. On 27 April HAGURO was reported as having been torpedoed by an Allied submarine; curiously enough the attack on ASHIGARA (by the Dutch submarine Hr.Ms. O-19) during the same time period was likewise reported.

[6] On 4 March 2003, a group of divers, again including Kevin Denlay, operating off MV EMPRESS locate the wreck of HAGURO in about 220 ft/67 m of water. She sits upright, covered in trawler nets, with her hull opposite her forward turrets buried in the seabed to about her original waterline, but this level gradually reduces until at the stern her outer propellers and shafts are actually up above the seabed! HAGURO's foremast and the top half of the bridge structure are missing/collapsed. Her mainmast is collapsed. Her funnels are missing. British hits are visible in places. The bow section forward of No. 2 turret is decimated. HAGURO's No. 1 turret and barbette are completely uprooted and now lay across the wreck, the rear of the turret on the starboard sea bed and the barrels pointing towards the surface. Her No. 2 turret was observed being trained to starboard at approximately the 1 o'clock position, with its roof collapsed and both barrels missing. Her No. 3 turret's guns are askew and trained to the port quarter, i.e. the 8 o'clock position. Both her stern main turrets point almost directly astern. Just behind the No. 5 turret, the wreck is broken completely in half, although the very stern section, heavily damaged on the port side, is still partially attached.

In December 2010, Kevin Denlay and a group of divers returned to the wreck of HAGURO. Diver Andrew Fock reports that they had the great visibility and conditions on the site and that contrary to 2003 observations, No. 2 turret is not pointing to starboard, but is facing towards the bow.

Special thanks for assistance in researching the IJN officers mentioned in this TROM go to Mr. Jean-François Masson of Canada and to Hans Mcilveen of the Netherlands for info on FRUMEL intercepts. Thanks also go to John Whitman of the USA for info on CNO intercepts of Japanese messages and troop movement in 1937. Thanks also go to John Whitman and Gengoro Toda for info on stores ship KITAKAMI MARU.
