Battle of the Java Sea

Background

The Japanese invasion of the Dutch East Indies progressed at a rapid pace as they advanced from their Palau Islands colony and captured bases in Sarawak and the southern Philippines. They seized bases in eastern Borneo and in northern Celebes while troop convoys, screened by destroyers and cruisers with air support provided by swarms of fighters operating from captured bases, steamed southward through the Makassar Strait and into the Molucca Sea. To oppose these invading forces was a small force, consisting of Dutch, American, British & Australian warships—many of them of World War I vintage—initially under the command of Admiral Thomas C. Hart.

On 23 January 1942, a force of four American destroyers attacked a Japanese invasion convoy in Makassar Strait as it approached Balikpapan in Borneo. On 13 February, the Allies fought unsuccessfully—in the Battle of Palembang—to prevent the Japanese from capturing the major oil port in eastern Sumatra. On the night of 19/20 February, an Allied force attacked the Eastern Invasion Force off Bali in the Battle of Badung Strait. Also on 19 February, the Japanese made two air raids on Darwin, on the Australia mainland, one from carrier based planes and the other by land based planes. The destruction of Darwin rendered it useless as a supply and naval base to support operations in the East Indies.

Shortly before the battle commenced, the odds were not good for the Allied forces. They lacked cohesion (ships came from four separate navies) and were demoralized by constant air attacks and a general sentiment that the Japanese were unbeatable. In addition, the coordination between Allied navies and air forces was poor.

Battle

The Japanese amphibious forces gathered to strike at Java, and on 27 February 1942, the main Allied naval force, under Doorman, sailed northeast from Surabaya to intercept a convoy of the Eastern Invasion Force approaching from the Makassar Strait. The Eastern Strike Force, as it was known, consisted of two heavy cruisers (HMS Exeter and USS Houston), three light cruisers (Doorman's flagship HNLMS De Ruyter, HNLMS Java, HMAS Perth), and nine destroyers (HMS Electra, HMS Encounter, HMS Jupiter, HNLMS Kortenaer, HNLMS Witte de With, USS Alden, USS John D. Edwards, USS John D. Ford, and USS Paul Jones).

The Japanese task force protecting the convoy, commanded by Rear-Admiral Takeo Takagi, consisted of two heavy (Nachi and Haguro) and two light cruisers (Naka and Jintsū) and 14 destroyers (Yūdachi, Samidare, Murasame, Harusame, Minegumo, Asagumo, Yukikaze, Tokitsukaze, Amatsukaze, Hatsukaze, Yamakaze, Kawakaze, Sazanami, and Ushio) including the 4th Destroyer Squadron under the command of Rear Admiral Shoji Nishimura. The Japanese heavy cruisers were much more powerful, armed with ten 8-inch (203 mm) guns each, and superb torpedoes. By comparison, Exeter was armed only with six 8-inch guns and only six of Houston's nine 8-inch guns remained operable after her aft turret had been knocked out in an earlier air attack.

The Allied force engaged the Japanese in the Java Sea, and the battle raged intermittently from mid-afternoon to midnight as the Allies tried to reach and attack the troop transports of the Java invasion fleet, but they were repulsed by superior firepower. The Allies had local air superiority during the daylight hours, because Japanese air power could not reach the fleet in the bad weather. The weather also hindered communications, making cooperation between the many Allied parties involved—in reconnaissance, air cover and fleet headquarters—even worse than it already was. The Japanese also jammed the radio frequencies. Exeter was the only ship in the battle equipped with radar, an emerging technology at the time.

The battle consisted of a series of attempts over a seven-hour period by Doorman's Combined Striking Force to reach and attack the invasion convoy; each was rebuffed by the escort force with heavy losses being inflicted on the Allies.

The fleets sighted each other at about 16:00 on 27 February and closed to firing range, opening fire at 16:16. Both sides exhibited poor gunnery and torpedo skills during this phase of the battle. Despite her recent refit (with the addition of modern Type 284 gunnery control radar), Exeter's shells did not come close to the Japanese ships, while Houston only managed to achieve a straddle on one of the opposing cruisers. The only notable result of the initial gunnery exchange was Exeter being critically damaged by a hit in the boiler room from an 8-inch shell. The ship then limped away to Surabaya, escorted by Witte de With.

The Japanese launched two huge torpedo salvoes, consisting of 92 torpedoes in all, but scored only one hit, on Kortenaer. She was struck by a Long Lance, broke in two and sank rapidly after the hit.

Electra—covering Exeter—engaged in a duel with Jintsū and Asagumo, scoring several hits but suffering severe damage to her superstructure. After a serious fire started on Electra and her remaining turret ran out of ammunition, abandon ship was ordered. On the Japanese side, only Asagumo was forced to retire because of damage.

The Allied fleet broke off and turned away around 18:00, covered by a smoke screen laid by the four destroyers of U.S Destroyer Division 58 (DesDiv 58). They also launched a torpedo attack but at too long a range to be effective. Doorman's force turned south toward the Java coast, then west and north as night fell in an attempt to evade the Japanese escort group and fall on the convoy. It was at this point the ships of DesDiv 58—their torpedoes expended—left on their own initiative to return to Surabaya.

Shortly after, at 21:25, Jupiter ran onto a mine and was sunk, while about 20 minutes later, the fleet passed where Kortenaer had sunk earlier, and Encounter was detached to pick up survivors.

Doorman's command, now reduced to four cruisers, again encountered the Japanese escort group at 23:00; both columns exchanged fire in the darkness at long range, until De Ruyter and Java were sunk, by one devastating torpedo salvo. Doorman and most of his crew went down with De Ruyter; only 111 were saved from both ships.

Only the cruisers Perth and Houston remained; low on fuel and ammunition, and following Doorman's last instructions, the two ships retired, arriving at Tanjung Priok on 28 February.

Although the Allied fleet did not reach the invasion fleet, the battle did give the defenders of Java a one-day respite.

Battle of Sunda Strait

Perth and Houston were at Tanjung Priok on 28 February when they received orders to sail through Sunda Strait to Tjilatjap. Material was running short in Java, and neither was able to rearm or fully refuel. Departing at 21:00 on 28 February for the Sunda Strait, by chance they encountered the main Japanese invasion fleet for West Java in Bantam Bay. The Allied ships were engaged by at least three cruisers and several destroyers.

In a ferocious night action that ended after midnight on 1 March, Perth and Houston were sunk. A Japanese minesweeper and a troop transport were sunk by friendly fire, while three other transports were damaged and had to be beached.

Second Java Sea

After emergency repairs the badly-damaged Exeter left Surabaya for Ceylon; she departed at dusk on 28 February and limped toward Sunda Strait, escorted by the destroyers HMS Encounter and USS Pope. However, all three ships were intercepted by the Japanese heavy cruisers Nachi, Haguro, Myōkō and Ashigara—and their attendant destroyers—on the morning of 1 March. Exeter and Encounter were sunk together around noon, while Pope escaped only to be sunk several hours later by aerial attack.

Bali Strait

The four U.S destroyers of DesRon 58—John D. Edwards, John D. Ford, Alden, and Paul Jones—were also at Surabaya; they left for Australia at nightfall on 28 February. After a brief encounter with a Japanese destroyer in the Bali Strait, which they were able to evade, they reached Fremantle safely on 4 March.

Consequences

A further Dutch and two American destroyers were sunk as they attempted to escape to Australia. The main ABDA naval force had been almost totally destroyed: 10 ships and approximately 2,173 sailors had been lost. The Battle of the Java Sea ended significant Allied naval operations in South-East Asia in 1942, and Japanese land forces invaded Java on 28 February. The Dutch surface fleet was practically eradicated from the Asian waters and the Netherlands would never reclaim full control of its colony. The Japanese had laid open the control of one of the most important food-producing regions, Java, and by conquering the Dutch East-Indies Japan also gained ultimate control over the sources of the fourth largest oil producer in the world in 1940.

The U.S. and Royal Air Force then started to retreat to Australia. Dutch troops, aided by British remnants, fought fiercely for a week. In the campaign the Japanese executed many Allied POWs and sympathizing Indonesians. Eventually, the Japanese won this decisive battle of attrition and ABDA forces surrendered on 9 March.

Missing Shipwrecks

On 16 November 2016, it was reported that the wrecks of six and a half Allied ships which sank during the battle were missing from the ocean floor. The BBC quoted the Dutch Defense Ministry as saying that two Dutch shipwrecks, and large parts of a third, were missing, naming them as HNLMS De Ruyter, HNLMS Java and HNLMS Kortenaer. The Guardian reported that the wrecks of HMS Exeter, HMS Encounter, and part of HMS Electra, as well as the submarine USS Perch were missing from the ocean floor and presumed illegally scavenged.
