8 June 1945:
Departs Batavia with KAMIKAZE for Singapore via the Bangka Strait. BLUEBACK reports her departure northbound, but is unable to attack. TRENCHANT negotiates a minefield in the northern entrance to the Banka Strait and takes up position on the inside of the Strait. STYGIAN takes the other side. Hezlet remains on the surface.
KAMIKAZE dashes up the Strait and takes TRENCHANT under fire. STYGIAN fires a torpedo at the destroyer, but misses. Hezlet crash dives. As depth charges explode nearby, he sights ASHIGARA coming north, hugging the Sumatran coast.
At 1215, Cdr Hezlet fires eight Mark VIII torpedoes from his bow and deck tubes at ASHIGARA from 4,700 yards. The cruiser's lookouts spot the torpedoes, but she is trapped between the shore and a minefield. ASHIGARA tries to turn into and comb the torpedoes, but she cannot complete the maneuver in time. She is hit by five torpedoes and reduced to a wreck. She moves ahead slowly and her AA guns open fire briefly on TRENCHANT's periscope. After some thirty of his crewmen observe the sinking cruiser through the periscope, Hezlet circles to bring his stern tubes to bear and fires two more torpedoes.
At 1237, ASHIGARA capsizes and sinks at 01-59S, 104-56E. KAMIKAZE rescues 853 crewmen and about 400 army troops.
Rear Admiral Miura survives the sinking of his ship and is rescued by KAMIKAZE. On 20 June 1945 he is posted as Assistant Chief of Staff, 2nd Southern Expeditionary Fleet.
20 August 1945:
Removed from Navy List.
 Spithead is located on the eastern part of the channel between Hampshire and the Isle of Wight.
 Early in 1936, the British Air Ministry established the Bawdsey Research Station, Suffolk, as the center for all pre-war radar experiments for both the Air Force and the Army. Experimental equipment was brought up to a high state of reliability and ranges of over 100 miles on aircraft were obtained. In 1937, a prototype Radio Detection Finding (RDF) station (called Chain Home) was handed over to the Royal Air Force. The first of three major pre-war air-defence exercises was carried out in the summer of 1937.
 The courtesy meeting with Hitler was in return for the Emperor's receiving the captains of some German cruisers that visited Japan in the '30s.
 Mt. Niitaka, located in Formosa (now Taiwan), was the highest point in the Japanese Empire at the time.

 In September 1943, Lt A. R. Hezlet's submarine HMS THRASHER tows the midget submarine HMS X5 from Loch Cairnbawn, Scotland to Kaafjord, Norway to join with five other midgets in an attack on German battleship TIRPITZ in Operation "Source". Four charges explode under TIRPITZ and put her out of action for months. In October 1944, at Phuket, Malaya, LtCdr Hezlet's HMS TRENCHANT successfully launches two Mark II Chariot midgets against Italian liners SUMATRA and VOLPI. Admiral Hezlet dies in Nov 2007 at age 93.
 In July 1945, Lt G. C. Clarabut's submarine HMS STYGIAN tows the midget submarine HMS XE3 from Brunei to an area near Singapore from which the midget attacks and blows the bottom out of anchored cruiser TAKAO in Operation "Struggle".
 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. The two warships were found at a depth of about 60m/200ft, 90 miles north of Bawean Island, about 350 nautical miles from Sunda Strait. EXETER lays on her starboard. Her faithful consort ENCOUNTER rests about two miles away. About 50 of EXETER's crew were killed, while 650 were made prisoners of war. Of these, 152 died in Japanese PoW camps. About eight of ENCOUNTER's crew were killed and 149 were made PoWs, of whom 38 died in captivity.
 On 3 March 1942, destroyer INAZUMA returned to the scene and rescued 151 of POPE's crew from life rafts and a lone whaleboat. Only one of POPE's crewmen was lost in the battle. INAZUMA landed the POWs at Makassar, Celebes. Earlier, on 1 March, INAZUMA had rescued 376 of EXETER and ENCOUNTER's crewmen.
 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 operating out of Singapore. The old destroyer appears to have been found earlier by Indonesian salvage divers and very little remains but a rusted iron ‘skeleton’. The destroyer had been heavily damaged by the salvors using explosive charges.
Special thanks for assistance in researching the IJN officers mentioned in this TROM go to Mr. Jean-François Masson of Canada. Thanks also go to Randy Stone of the United States and "Adm. Gurita" of the Netherlands. Kudos also go to Andrew Obluski of Poland who provided some outstanding details of ASHIGARA's pre-war activity. - Bob Hackett and Sander Kingsepp.
