[edit] Forces

The Japanese forces were split into two groups: the Eastern Force, with its headquarters at Jolo Island in the Sulu Archipelago, included the 48th Division and the 56th Regimental Group. The Western Force, based at Cam Ranh Bay, French Indochina included the 2nd Division and the 230th Regiment (detached from the 38th Division).

The Allied forces were commanded by the Royal Netherlands East Indies Army (KNIL) commander, General Hein ter Poorten. Although the KNIL forces had, on paper, 25,000 (mostly Indonesian) well-armed troops, many were poorly trained. The KNIL forces were deployed in four sub-commands: Batavia (Jakarta) area (two regiments); north central Java (one regiment); south Java (one regiment) and; east Java, one regiment.

The British, Australian and United States units were commanded by British Major General H. D. W. Sitwell. The British forces were predominantly anti-aircraft units: the 77th Heavy AA Regiment, 21st Light AA Regiment and 48th Light AA Regiment. The only Allied armoured unit in Java was a squadron of tanks from the British 3rd Hussars. Two British AA regiments without guns, the 6th Heavy AA Regt and the 35th Light AA Regiment were equipped as infantry to defend airfields. The British also had transport and administrative units.

The Australian formation — named "Blackforce" after its commander, Brigadier Arthur Blackburn V.C. — included the Australian 2/3rd Machine Gun Battalion, the Australian 2/2nd Pioneer Battalion, a company from the Royal Australian Engineers, a platoon from the 2/1st Headquarters Guard Battalion,^[1] about 100 reinforcements diverted on route to Singapore, a handful of soldiers who had escaped from Singapore following its fall to the Japanese, two transport companies, a casualty clearing station, and a company headquarters unit. Blackburn decided to re-organise his troops as an infantry brigade. They were well-equipped in terms of Bren guns and light armoured cars, but they had few rifles, submachineguns, anti-tank rifles, mortars, grenades, trucks, radio equipment or Bren gun carriers. Blackburn managed to assemble an HQ staff and three infantry battalions based on the 2/3rd Machine Gun, the 2/2nd Pioneers, and a mixed "Reserve Group". The only U.S. ground forces in Java, the 2nd Battalion of the 131st Field Artillery (a Texas National Guard unit) was also attached to Black Force.

[edit] Japanese landings

The Japanese troops landed at three points on Java shore on the same day, March 1, 1942. The West Java invasion convoy landed on Bantam Bay near Merak and Eretan Wetan. The West Java convoy had previously fought in the Battle of Sunda Strait, a few hours prior to the landings.

Meanwhile the East Java invasion convoy landed on Kragan after having successfully defeated the ABDA fleet in the Battle of the Java Sea.

[edit] West Java Campaign

[edit] West Java Campaign from Merak and Bantam Bay

After discussing the war preparation on January 21 with the commander of the 3rd Fleet and inspected the 48th Division at Manila, Lieutenant General Hitoshi Imamura received an order to attack Java on January 30, 1942.

The convoy consisted of 56 transport ships with troops aboard from 16th Army Headquarters, 2nd Division and 230th Infantry Regiment. The convoy left Cam Ranh Bay at 10:00 on February 18, and the commander-in-chief Lieutenant General Hitoshi Imamura was aboard on the transport ship Ryujo Maru. The convoy escort was under the command of Rear Admiral Kenzaburo Hara.

On February 28 at 23:20, the transport ships carrying the Nasu and Fukushima detachments commenced landing operations at Merak. Ten minutes later they were joined by the other transport ships; the one carrying the Sato detachment dropped anchor at Bantam Bay. By 02:00 on March 1, all ships had reached their designated positions. The KNIL Merak Coastal Detachment, made up of a section from the Captain F.A.M. Harterink's 12th KNIL Infantry Battalion, machine-gunned the invaders but was quickly defeated.

On March 1, the invaders set up new headquarters at Serang. The troops of the 2nd Division led by Lieutenant-General Masao Maruyama were divided into the following detachments:

• Nasu Detachment : Major-General Yumio Nasu
• Fukushima Detachment : Colonel Kyusaku Fukushima
• Sato Detachment : Colonel Hanshichi Sato

The Nasu detachment was ordered to capture Buitenzorg to cut the escape route from Batavia to Bandoeng. The Fukushima and Sato Detachments would in the meanwhile head for Batavia through Balaradja and Tangerang.

On March 2, the Nasu detachment arrived at Rangkasbitung and continued to Leuwiliang, 24 kilometres (15 mi) west of Buitenzorg. The Australian 2/2nd Pioneer and 2/3rd Machine Gun Battalions were positioned along a riverbank at Leuwiliang and put up a vigorous defence. Highly accurate volleys from "D" Battery, U.S. 2/131st Field Artillery, destroyed many Japanese tanks and trucks. Blackforce managed to hold up the Japanese advance for two full days before being forced to withdraw to Soekabumi, lest it become trapped by Japanese flanking manouevres, and was ordered to retreat to Soekabumi. Around the same time, the Fukushima and Sato units headed westwards to Madja (Maja) and Balaradja (Balaraja). They found many of the bridges already destroyed by the retreating Dutch and were forced to find other routes; some units took the opportunity to make for Buitenzorg.

On March 4, Ter Poorten decided to withdraw his forces from Batavia and Buitenzorg to reinforce the defence of Bandoeng. The following evening Dutch troops in Batavia surrendered to the Sato Detachment. By dawn of March 6, the Japanese troops had attacked Buitenzorg, which was guarded by the 10th Company, KNIL 2nd Infantry Regiment; 10th Company, 1st Infantry Regiment; Landstorm troops and a howitzer unit. In the morning Buitenzorg was occupied, while a large number of Allied soldiers had retreated to Bandoeng. The Nasu Detachment pursued them through Tjiandjoer and (Tjimahi), entering the city on March 9. The Shoji Detachment also entered Bandoeng on the same day, arriving from the north, having travelled via Lembang.

[edit] West Java Campaign from Eretan Wetan

On February 27, the unit 230th Infantry Regiment, led by Colonel Toshishige Shoji, separated from the main convoy and landed on March 1, at Eretan Wetan, near Soebang on the northern coast of West Java. The unit's objectives were to capture the important Kalidjati airfield and weaken the Allied air arm, while the 2nd Division attacked Batavia.

At dawn on March 1, 9 Brewster and 3 Glenn Martins from the KNIL Air Force, together with 12 Hurricanes from the 242nd and 605th RAF Squardrons, carried out attacks on Japanese troops at Eretan Wetan. Using motor vehicles, the Japanese rapidly advanced to Soebang. At noon the Kalidjati airfield was finally occupied following a tenacious defence carried out by 350 British troops. Meanwhile other Japanese units led by Major Masaru Egashira bypassed Allied defences and headed for Pamanoekan (Pamanukan), and from then on to (Tjikampek), where they were able to cut the road link between Batavia and Kalidjati.

The fall of Kalidjati airfield greatly alarmed the Dutch, who set about planning hasty and ill-prepared counterattacks. On March 2, a KNIL armoured unit (the Mobiele Eenheid), commanded by Captain G.J. Wulfhorst with approximately 20 tanks, and supported by the 250 men of Major C.G.J. Teerink's 5th KNIL Infantry Battalion, launched a counterattack against the Shoji unit outside Soebang. The attempt initially went well, but in the afternoon the attack was repulsed. Afterwards, the main force of Japanese 3rd Air Brigade arrived at Kalidjati airfield.

By night of March 7, Japanese troop had arrived at the plateau of Lembang, which is only 8 kilometres (5 mi) northward from Bandoeng. At 10:00 on March 8, Major-General Jacob J. Pesman, the commander of Bandoeng district, met Colonel Toshishige Shoji at the Isola Hotel in Lembang and surrendered.

[edit] East Java Campaign

[edit] Moving eastward

The East Java campaign was composed of the 48th Division from the Philippines. On February 8, 1942, the 48th Division departed from Lingayen Gulf, Luzon Island (Philippines) protected by the 4th Destroyer Squadron. On February 22, the convoy arrived at Balikpapan and the Sakaguchi Detachment joined the 48th Division aboard the ships.

On February 25, the convoy left Balikpapan, and sailed southward to Java. On February 27, the ABDA fleet under command of Rear-Admiral Karel Doorman was detected and attacked by the 5th Destroyer Squadron and other units of the 3rd Fleet in Battle of the Java Sea. The Japanese won the battle and at 00:15 on March 1, and the fleet landed on Kragan, a small village in East Java, approximately 160 kilometres (100 mi) west of Surabaya.

The 3rd (Motorised) Cavalry Squadron of the 1st Dutch KNIL Cavalry Regiment, under the command of Ritmeester C.W. de Iongh, resisted the landing force but was quickly subdued.

Meanwhile, the flying boat Dornier X-28 of the 6th GVT (Groep Vliegtuigen or Aircraft Group) from MLD, B-17 bombers of the U.S. 7th Bomber Group, A-24 dive bombers of the U.S. 27th Bomb Group and Vildebeest torpedo-bombers from the 36th RAF Squadron worked round the clock to harass the invaders.

After landing, the 48th Division was divided into:

• Imai Unit (Right Wing) : Colonel Hifumi Imai
• Abe Unit (Left Wing) : Major-General Koichi Abe
• Tanaka Unit (Tjepoe Raiding Unit) : Colonel Tohru Tanaka
• Kitamura Unit (Bodjonegoro Raiding Unit) : Lieutenant Colonel Kuro Kitamura

The Tanaka Unit was ordered to occupy Tjepoe (Cepu) to secure the oilfields there and the Kitamura Unit was to occupy Bodjonegoro, near Tjepoe. The whole unit planned two pronge attack Surabaya from the west through Lamongan and from south through Djombang and Modjokerto.

The Tanaka Unit occupied Tjepoe on March 2 while the Kitamura Unit occupied Bodjonegoro on March 3. The Japanese proceeded further and overwhelmed the Dutch defences at the Ngawi Regency, Tjaroeban (Caruban), Ngandjoek, Kertosono, Kediri and Djombang.

At Porong, near Surabaya, the Dutch infantry from 8th, 13th Battalion, 3rd Cavalry unit and the American 131st (Texas) "E" Field Artillery Regiment gave fierce resistance to the incoming Japanese. Eventually the Allied troops under Major-General Gustav A. Ilgen had to retreat to the island of Madura upon the completion of demolition of the city's infrastructure. On the evening of March 9, Major-General Ilgen, commander of the KNIL in East Java, signed the instrument of surrender.

[edit] Moving southward

The Sakaguchi Detachment from Balikpapan joined the East Java Invasion fleet as well. After landing they were divided into 3 units with 1 battalion each:

• Kaneuji Unit : Major Kaneuji
• Yamamoto Unit : Colonel Yamamoto
• Matsumoto Unit : Lieutenant Colonel Matsumoto

and moved southward with main objective to occupy Tjilatjap in order to capture the harbour and block the retreat to Australia. In one week, they advanced rapidly and overcame all Dutch army defence found in Blora, Soerakarta, Bojolali, Jogjakarta, Magelang, Salatiga, Ambarawa and Poerworedjo. The Kaneuji and Matsumoto Detachments moved through mainland, captured Keboemen and Purwokerto, north of Tjilatjap on March 8. The Yamamoto Unit fanned out along the beach and mounted a two-pronged attack, entering Tjilatjap on March 8. By then, however, the Dutch had withdrawn to Wangon, a small town located between Purwokerto and Tjilatjap. On the following day Major-General Pierre A. Cox, the Dutch Central Army District commander, surrendered his troops to the Japanese.

[edit] Dutch surrender

By March 7, defeat was inevitable, with Tjilatjap already in Japanese hands. Soerabaja was being evacuated while Japanese troops were rapidly converging on Bandoeng from both the north and the west. At 09:00 on March 8 the Commander-in-Chief of the Allied forces, Ter Poorten, announced the surrender of the Royal Netherlands East Indies Army in Java.

At 23:00 the Dutch radio station NIROM (Nederlandsch Indische Radio Omroep Maatschappij) broadcasted the last news from a temporary transmitter at Ciumbuluit. The announcer Bert Garthoff ended the broadcast with the words "Wij sluiten nu. Vaarwel tot betere tijden. Leve de Koningin!" (We are closing now. Farewell till better times. Long live the Queen!)

The Dutch Governor, Jonkheer Dr. A.W.L. Tjarda Van Starkenborgh Stachouwer and Lieutenant-General Ter Poorten, together with Major-General Jacob J. Pesman, the commander of the Bandoeng District, met the Japanese Commander-in-Chief, Lieutenant-General Hitoshi Imamura at Kalidjati that afternoon and agreed to the capitulation of all the troops.

[edit] Aftermath

On March 10, Lieutenant-General Hitoshi Imamura became the new governor of Java and Madura, thus becoming the highest authority in the occupied Dutch East Indies. He stayed on this position for approximately eight months, until November 11, 1942. Imamura was subordinated to Field Marshall Count Hisaichi Terauchi, the Supreme Commander of the Southern Army, headquartered in Saigon, French Indochina. He was also the governor of the so-called "Southern Territories" (Malaya, Burma, the Philippines, Hong Kong, Java, Sumatra, and Borneo) and directly subordinated to the Imperial Headquarters in Tokyo, Japan.

On March 12, 1942, the senior British, Australian and American commanders were summoned to Bandoeng where the formal instrument of surrender was signed in the presence of the Japanese commander in the Bandoeng area, Lieutenant-General Masao Maruyama, who promised them the rights of the Geneva Convention for the protection of prisoners of war.

Immediately after this, the widely-spread Japanese troops were reorganised. The 16th Army (2nd Division and 48th Division) was ordered to guard of Java, while the eastern territory (Lesser Sunda islands, Celebes, Ambon and Netherlands New Guinea) became the responsibility of the Imperial Navy. The other units were deployed to other combat areas in Pacific or returned to Japan.

The surrender of the Dutch marked the end of the ABDA defence in the Dutch East Indies and the collapse of the "Malay Barrier" (or "East Indies Barrier"). Because the Allied naval force had been destroyed, the Indian Ocean and the approach to Australia lay open to the Imperial Japanese Navy.
