F. M. Doorman's Strike Force's light cruiser HNMS DE RUYTER, cruisers HMS EXETER, USS HOUSTON (CA-30), light cruisers HMAS PERTH, HNMS JAVA, destroyers HMS ELECTRA, ENCOUNTER, JUPITER, HNMS KORTENAER and WITTE de WITH and old destroyers USS ALDEN (DD-211), JOHN D. EDWARDS (DD-216), JOHN D. FORD (DD-228) and PAUL JONES (DD-230).
At 1603, DesRon 4's light cruiser NAKA with DesDiv 9's ASAGUMO, MINEGUMO, MURASAME, HARUSAME, SAMIDARE and YUDACHI launch their Type 93 "Long Lance" torpedoes at Doorman's force. At 1638, EXETER is hit in her boilers by HAGURO. At 1640, HNMS KORTENAER hit by a torpedo from HAGURO, blows up and sinks.
At about 1700, NACHI launches her two Aichi E8N1 Type 95 "Dave" spotting planes. The pilots gain altitude and see the floatplanes from HAGURO also positioning themselves over the ABDA fleet for spotting. They search the sky for enemy planes, but find none.
At 1746, HMS ELECTRA and ASAGUMO engage in a gun battle. ELECTRA is sunk. At 2000, HMS JUPITER hits a Dutch mine and sinks. 
Later, American LtCdr (later Captain) Henry G. Munson's submarine USS S-38 surfaces and rescues 58 ELECTRA crewmen from the water.
NACHI's floatplanes continue to fly until after dark. During their recovery, NACHI and HAGURO are surprised by the Allied Striking Force, but manage to make a swift and narrow escape.
At 2336, Dutch Captain P. B. M. Van Straelen's light cruiser JAVA is hit by a torpedo. Soon thereafter, her stern breaks off.
At 2340, the Allied flagship, Dutch Cdr Eugène E. B. Lacomblé's HNMS DE RUYTER is hit by a torpedo from HAGURO and set afire aft. As a result of a complete power failure, the fire can not be extinguished, but DE RUYTER remains afloat for about three hours. Rear Admiral Doorman and 344 crewmen are killed. At 2345, JAVA sinks taking down 512 crewmembers including Captain van Straelen. HOUSTON and PERTH retire to Batavia (Djakarta), Java. 
28 February 1942:
At 1900, after refueling, HOUSTON and PERTH sortie for Tjilatjap via the Sunda Strait. At 2215, they attack Japanese troop transports screened only by destroyers HARUSAME, HATAKAZE and FUBUKI. The destroyers make smoke to mask the transports. FUBUKI charges and launches a salvo of torpedoes at HOUSTON and PERTH.
At 2300, the Western Support Force's MIKUMA and MOGAMI, destroyer SHIKINAMI, Third Escort Force's light cruiser NATORI and destroyers SHIRAKUMO, MURAKUMO, SHIRAYUKI, HATSUYUKI and ASAKAZE arrive and engage HOUSTON and PERTH with gunfire and torpedoes.
During the battle, the Japanese fire about 90 torpedoes. Post-battle analyses indicate that MOGAMI's and FUBUKI's torpedoes probably sank five Japanese transports including RYUJO MARU carrying the commander of the invading 16th Army, LtGen Imamura Hitoshi. Imamura jumps into the sea, but survives.
At 2308, torpedoes strike both HOUSTON and PERTH.
1 March 1942:
A fourth torpedo hits PERTH. At 0025, she sinks about three miles ENE of St. Nicholas Point, Java at 05-51-42S, 106-07-52E. At 0045, HOUSTON sinks NW of Pandjang Island at 05-48-45S, 106-07-55E.

At 1150, the Support Force's ASHIGARA and MYOKO with destroyers AKEBONO and INAZUMA also sight and exchange fire with the EXETER group. At 1245, NACHI and HAGURO also open fire on EXETER.
At 1250, EXETER is hit by shells, set afire and goes dead in water. AKEBONO and INAZUMA launch 18 torpedoes. At 1330, EXETER sinks. MYOKO and ASHIGARA damage LtCdr E. V. St. J. Morgan's destroyer HMS ENCOUNTER by a near miss from an 8-inch salvo. 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. 
Old destroyer POPE escapes the engagement with the cruisers, only to be sunk at 1540 in attacks by aircraft from CHITOSE, MIZUHO and RYUJO. 
That same day, LtCdr W. G. Chapple’s USS PERMIT (SS-178) sights “a heavy cruiser, two light cruisers and several destroyers” N of Surabaya. In fact, this may be NACHI and HAGURO. Chapple makes an approach and fires three torpedoes at a destroyer from only 600 yards – but misses.

North Pacific, off the Kamchatka Peninsula, Siberia. Rear Admiral (later Vice Admiral) Charles H. McMorris (former CO of SAN FRANSCISCO, CA-38) Task Group 16.6's USS RICHMOND (CL-9)(F), SALT LAKE CITY (CA-25) and destroyers BAILEY (DD-492), DALE (DD-353), MONAGHAN (DD-354) and COGHLAN (DD-606) engage Vice Admiral Hosogaya's Fifth Fleet cruisers NACHI (F), MAYA, TAMA and ABUKUMA and two destroyers that are escorting Convoy "D" carrying troops and supplies for the isolated garrison on Attu.
One of NACHI's three planes had been left behind for overhaul and MAYA had none of her three planes with her. On contact with the Americans, NACHI's two planes are ordered launched. At 0540, before they can be catapulted, NACHI's main battery opens fire. The gun blast damages the two-seat Type 0 spotter plane on the starboard catapult, probably a Nakajima E8N2 "Dave". It has to be jettisoned. The remaining three-seat E13A1 "Jake" on the port catapult is launched. It carries out spotting duties throughout the action and then flies to Attu, but crashes on landing. About a month later, its crew returns to Japan by submarine.
NACHI launches Type 93 "Long Lance" torpedoes at McMorris' force, but scores no hits. In a four-hour running gun battle, SALT LAKE CITY and BAILEY are damaged by gunfire. The other American destroyers are not damaged. Five shells hit and damage NACHI. Fourteen crewmen are killed. MAYA's No. 1 gun turret is knocked out.

Ashley closes to 3,000 yards on the surface and fires his four stern tubes by radar bearings at the "carrier" and an overlapping cruiser at 21-57N, 118-14E. Ashley then takes SEADRAGON deep and evades. Later, he claims hiots on both ships, but postwar these are substantiated.
At 0855, LtCdr Richard W. Peterson's submerged USS ICEFISH (SS-367) spots a destroyer, then sights a task force of two NACHI-class heavy cruisers, escorted by three destroyers, bearing 064 T, course 160 T, speed 16 to 18 knots. ICEFISH cannot gain a position closer than 8,000 yards and is unable to attack. In heavy seas, Peterson surfaces to get off a contact report, but is forced under by Japanese planes before he can get off a report. Later that night, he tries again and is successful.
23 October 1944:
Arrives safely at Coron.
24 October 1944 - Operation "SHO-I-GO"(Victory) - The Battle of Leyte Gulf:
Departs Coron to support Vice Admiral Nishimura Shoji's (former CO of HARUNA) First Raiding Force's BatDiv 2's YAMASHIRO, FUSO, cruiser MOGAMI.
Surigao Strait. At about 0420 that night, ASHIGARA and NACHI pick up two targets on their surface-search radars. Vice Admiral Shima orders a torpedo attack and the cruisers turn to starboard to bring their tubes to bear. At 0427, each cruiser launches eight torpedoes by radar, but they obtain no hits.
At 0429, NACHI collides with MOGAMI that is retiring southward. MOGAMI is holed starboard side above the waterline. NACHI's bow is rent portside and as she pulls clear, she begins to flood. Shima orders his force to retire.
25 October 1944:
Arrives at Coron and refuels with ASHIGARA.
26 October 1944:
NACHI and KUMANO and destroyers HATSUSHIMO, OKINAMI, KISHINAMI, SHIMAKZE, SHIRANUI and HATSUHARU are refueled by oiler NICHIEI MARU.
27 October 1944:
Departs Coron for Manila with ASHIGARA, DesDiv 7. ASHIGARA detaches for Palawan.
28 October 1944:
Arrives at Manila Bay. Drydocked at No. 103 Repair Facility at Cavite for repair of her bow plates.
29 October 1944:
Manila. NACHI and KUMANO are attacked by Task Force 38's carrier planes. A single bomb hits NACHI on her aircraft deck. 53 crewmen are killed by this and a straffing attack. This attack causes further delays to completing her temporary repairs.
2 November 1944:
Repairs to the bow are completed. Undocked. Provides distant cover for Operation "TA" troop reinforcement runs to Ormoc Bay, Leyte.
5 November 1944:
Off Cavite Naval Base. Vice Admiral Shima is ashore when Task Force 38 hits Manila with four successive waves of strike aircraft. After the second wave, undamaged NACHI gets underway for the safety of the open sea, but she is attacked by about 60 planes.
Off Corregidor Island. At 1250, NACHI is attacked by a third wave of Task Group 38.3's aircraft from USS TICONDEROGA (CV-14) and LEXINGTON (CV-16) About five bombs hit her and two, possibly three, torpedoes hit her in the starboard boiler rooms. NACHI is immobilized. Destroyer AKEBONO is dispatched to assist her.
At 1400, NACHI, on an even keel, is making preparations to get underway. She is joined by AKEBONO for a possible tow.
At 1445, another wave from LEXINGTON hits NACHI with up to five torpedoes in the port side that blast her into three pieces. One torpedo blows off her bow that sinks at once, another sets off her aft magazine that severs her stern. It upends but remains floating. The other three torpedoes hit her amidships. Twenty bombs and 16 rockets also hit her. Vice Admiral Shima watches from ashore as his flagship is blown apart.
At 1450, the central portion of NACHI sinks in 102 feet of water about twelve nautical miles NE of Corregidor at approximately 14-31N, 120-44E. 807 crewmen are killed including Captain Kanooka and 74 men of the Fifth Fleet's staff. 220 men survive the blasts and the strafing. KASUMI and USHIO rescue NACHI's survivors. USHIO tows damaged destroyer AKEBONO, hit by two bombs and set afire, to shore. 
Captain Kanooka is promoted to Rear Admiral, posthumously.
20 January 1945:
Removed from the Navy List.
Divers from USS CHANTICLEER (ASR-7) explore the wreck and salvage several radar consoles, secret documents, maps of Japanese fortifications on Luzon, as well as some two million yen. In all 296 dives are made.
 Mt. Niitaka, located in Formosa (now Taiwan), is the highest point in the Japanese Empire at the time.
 Mined HMS JUPITER sank about 10 miles off the coast of Java in only about 50 feet of water. As a result
of her easy accessibility, postwar she is heavily salved by Indonesian nationals.
 On 1 December 2002, a group of divers, including Australian photo-jounalist Kevin Denlay, operating off MV EMPRESS out of Singapore using side-scan sonar discover DeRUYTER and JAVA at a depth of about 225 feet off Bawean Island in the Java Sea.
 On 21 February 2007, a group of divers operating from MV EMPRESS out of Singapore, again 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 are 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.
 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’.

 In 2000, Kevin Denlay conducted a detailed search for the wreck of NACHI and discovered that the commonly published data (Lat / Longs, etc) for the wreck site, which have her sinking west or south west of Corregidor, were incorrect. Data from USS CHANTICLEER's deck log proved that the position where she was anchored over the NACHI wreck in 1945 was to the north east of Corregidor, well inside Manilla Bay, at approximately this location. Unfortunately, given that the relatively shallow water where NACHI sunk is now a shipping lane, it appears the remains of the wreck have been salvaged and completely removed over the intervening years because of the navigation hazard it would have posed to marine traffic transiting across Manilla Bay.
