The 8th Division was an infantry division of the Australian Army, formed during World War II as part of the all-volunteer Second Australian Imperial Force. The 8th Division was raised from volunteers for overseas service from July 1940 onwards. Consisting of three infantry brigades, the intention had been to deploy the division to the Middle East to join the other Australian divisions, but as war with Japan loomed in 1941, the division was divided into four separate forces, which were deployed in different parts of the Asia-Pacific region. All of these formations were destroyed as fighting forces by the end of February 1942 during the fighting for Singapore, and in Rabaul, Ambon, and Timor. Most members of the division became prisoners of war, waiting until the war ended in late 1945 to be liberated. One in three died in captivity.
The fall of Singapore, also known as the Battle of Singapore, took place in the South–East Asian theatre of the Pacific War. The Japanese Empire captured the British stronghold of Singapore, with fighting lasting from 8 to 15 February 1942. Singapore was the foremost British military base and economic port in South–East Asia and had been of great importance to British interwar defence strategy. The capture of Singapore resulted in the largest British surrender in its history.
The Malayan campaign, referred to by Japanese sources as the Malay Operation, was a military campaign fought by Allied and Axis forces in Malaya, from 8 December 1941 – 15 February 1942 during the Second World War. It was dominated by land battles between British Commonwealth army units and the Imperial Japanese Army, with minor skirmishes at the beginning of the campaign between British Commonwealth and Royal Thai Police. The Japanese had air and naval supremacy from the opening days of the campaign. For the British, Indian, Australian, and Malayan forces defending the colony, the campaign was a total disaster.
The Borneo campaign or Second Battle of Borneo was the last major Allied campaign in the South West Pacific Area during World War II to liberate Japanese-held British Borneo and Dutch Borneo. Designated collectively as Operation Oboe, a series of amphibious assaults between 1 May and 21 July 1945 were conducted by the Australian I Corps, under Lieutenant-General Leslie Morshead, against Imperial Japanese forces who had been occupying the island since late 1941 – early 1942. The main Japanese formation on the island was the Thirty-Seventh Army under Lieutenant-General Masao Baba, while the naval garrison was commanded by Vice-Admiral Michiaki Kamada. The Australian ground forces were supported by US and other Allied air and naval forces, with the US providing the bulk of the shipping and logistic support necessary to conduct the operation. The campaign was initially planned to involve six stages, but eventually landings were undertaken at four locations: Tarakan, Labuan, North Borneo and Balikpapan. Guerilla operations were also carried out by Dayak tribesmen and small numbers of Allied personnel in the interior of the island. While major combat operations were concluded by mid-July, localised fighting continued throughout Borneo until the end of the war in August. Initially intended to secure vital airfields and port facilities to support future operations, preparatory bombardment resulted in heavy damage to the island's infrastructure, including its oil production facilities. As a result, the strategic benefits the Allies gained from the campaign were negligible.
The Battle of Tarakan was the first stage in the Borneo campaign of 1945. It began with an amphibious landing by Allied forces on 1 May, code-named Operation Oboe One; the Allied ground forces were drawn mainly from the Australian 26th Brigade, but included a small element of Netherlands East Indies personnel. The main objective of the landing was the capture of the island's airfield. While the battle ended with success for the Allied forces over the Japanese defenders, this victory is generally regarded as having not justified its costs. The airfield was so heavily damaged that it ultimately could not be repaired in time to make it operational for other phases of the Allied campaign in Borneo.
The 18th Infantry Division was an infantry division of the British Army which fought briefly in the Malayan Campaign of the Second World War. In March 1939, after the re-emergence of Germany as a European power and its occupation of Czechoslovakia, the British Army increased the number of divisions in the Territorial Army (TA) by duplicating existing units. The 18th Infantry Division was formed in September 1939 as a second-line duplicate of the 54th Infantry Division, with men from Essex and the East Anglian counties of Norfolk, Suffolk and Cambridgeshire.
The 1st Malaya Infantry Brigade was a regular infantry brigade formed in 1939 with its headquarters in Singapore immediately after the outbreak of hostilities in Europe. The Brigade participated in the Battle of Singapore against the Japanese until the surrender of the garrison in February 1942.
The '5th Division' was an infantry division of the Imperial Japanese Army. Its call sign was the Koi (Carp) Division. The 5th Division was formed in Hiroshima in January 1871 as the Hiroshima Garrison, one of six regional commands created in the fledgling Imperial Japanese Army. Its personnel were drafted from Hiroshima, Yamaguchi and Shimane.
The Salamaua–Lae campaign was a series of actions in the New Guinea campaign of World War II. Australian and United States forces sought to capture two major Japanese bases, one in the town of Lae, and another one at Salamaua. The campaign to take the Salamaua and Lae area began after the successful defence of Wau in late January, which was followed up by an Australian advance towards Mubo as the Japanese troops that had attacked Wau withdrew to positions around Mubo. A series of actions followed over the course of several months as the Australian 3rd Division advanced north-east towards Salamaua. After an amphibious landing at Nassau Bay, the Australians were reinforced by a US regimental combat team, which subsequently advanced north up the coast.
The Battle of Kota Bharu began just after midnight on 8 December 1941 before the attack on Pearl Harbor. It was the first major battle of the Pacific War, and was fought between ground forces of the British Indian Army and the Empire of Japan.
The Battle of Muar was the last major battle of the Malayan Campaign during the Second World War. It took place from 14–22 January 1942 around Gemensah Bridge and on the Muar River. After the British defeat at Slim River, General Archibald Wavell, commander of ABDA, decided that Lieutenant General Lewis Heath's III Indian Corps should withdraw 240 kilometres (150 mi) south into the State of Johore to rest and regroup, while the 8th Australian Division would attempt to stop the Japanese advance.
The Battle of Kranji was the second stage of the Empire of Japan's plan for the invasion of Singapore during the Second World War. On 9 February 1942 the Imperial Japanese Army assaulted the north-western front of Singapore, capital of the Straits Settlements.
The 27th Brigade was a brigade-sized infantry unit of the Australian Army. The brigade was the last Second Australian Imperial Force infantry brigade raised for service during World War II. Initially assigned to the 9th Division, the brigade was transferred to the 8th Division shortly after it was raised. Training was undertaken around Bathurst, New South Wales throughout early 1941, before the brigade was sent to British Malaya in August 1941 to reinforce the 22nd Brigade, which had been dispatched earlier in the year. Following the Japanese invasion of Malaya, the brigade went into action in January 1942, taking part in the fighting along the western side of the Malay Peninsula. Its main action during this period came around Muar before the withdrawal to Singapore. In February, the brigade took part in the short lived Battle of Singapore. When the garrison surrendered on 15 February, the majority of the brigade's personnel were taken prisoner. They subsequently spent the remainder of the war in captivity before being released in August 1945.
The 22nd Brigade was a brigade-sized infantry unit of the Australian Army. It was briefly raised in 1912 as a Militia formation providing training as part of the compulsory training scheme. Later, during World War II, the brigade was raised as part of the all volunteer Second Australian Imperial Force in April 1940. Assigned to the 8th Division, in early 1941 the brigade was deployed to British Malaya where it formed part of the defensive garrison that was established there by the British, eventually establishing its headquarters in the Mersing–Endau area.
The 2/4th Machine Gun Battalion was an Australian Army unit raised for service with the all volunteer Second Australian Imperial Force during the Second World War. Formed in late 1940 as part of the 8th Division, the battalion was established to provide direct fire support to the division's infantry brigades. It was the fourth, and last, such unit raised within the 2nd AIF. The unit's personnel were largely drawn from the state of Western Australia and after formation, the battalion concentrated near Perth for basic individual training before moving to the Adelaide Hills to complete more advance manoeuvres.
The Battle of Finschhafen was part of the Huon Peninsula campaign in New Guinea during World War II and was fought between Australian and Japanese forces. The fighting took place between 22 September and 24 October 1943 following the landing at Scarlet Beach, which was followed by a two-pronged advance on Finschhafen as the Australian 20th Infantry Brigade advanced on the town from the north, while the 22nd Infantry Battalion drove from the south, having advanced from the landing beaches east of Lae. After the capture of Finschhafen, the Japanese forces in the area withdrew towards Sattelberg where they sought to hold the Australians before launching a counteroffensive, which subsequently threatened the landing beach. This attack was repelled by Australian and American forces, with heavy casualties being inflicted on the Japanese. In the aftermath, the Australians went on the offensive, capturing Sattelberg, and then advancing towards the Wareo plateau.
The 2nd Malaya Infantry Brigade was a regular infantry brigade formed in 1940 with its headquarters in Singapore following the wartime expansion and reinforcement of Malaya Command. The Brigade participated in the Malayan Campaign and the Battle of Singapore against the Japanese until the surrender of the garrison in February 1942.
The 2/29th Battalion was an infantry battalion of the Australian Army, which served during the Second World War. Formed in October 1940, the battalion served in Malaya as part of the 27th Brigade, which was assigned to the 8th Division. Recruited mainly from volunteers drawn from the state of Victoria, after completing its training around Bonegilla and then Bathurst, the 2/29th Battalion was sent to Malaya in August 1941 along with the rest of the 27th Brigade to bolster the Australian force there and subsequently fought in the Malayan Campaign following the Japanese attack in December 1941. The battalion fought several delaying actions along the west coast, including fighting around Bakri and Muar, and in Johore, before Allied forces withdrew across the Causeway to Singapore. The battalion later took part in the defence of Singapore in February 1942, but was captured after the garrison capitulated on 15 February. They spent the remainder of the war as prisoners of war, with many dying in captivity.
The 2/19th Battalion was an infantry battalion of the Australian Army, which was raised for service during the Second World War as part of the Second Australian Imperial Force. After being formed in mid-1940, the battalion was allocated to the 22nd Brigade, which was part of the 8th Division. After completing training in Australia, in early 1941 the 2/19th deployed to Malaya, as part of the Australian force despatched to help bolster the British garrison there as tensions with Japan heightened. Following the commencement of hostilities against Japan, the 2/19th fought several actions in Johore, before withdrawing across the Causeway to Singapore. There, the battalion was involved in the Battle of Singapore in early February 1942, during which it suffered heavy casualties before being captured following the capitulation of the British garrison. The battalion's personnel subsequently spent the next three-and-a-half years as prisoners of war, before being released at the end of the conflict.
The Battle of Roosevelt Ridge was fought between 21 July and 14 August 1943 between US and Japanese forces in the Salamaua area of the Territory of New Guinea during World War II. The battle was fought in conjunction with several other actions of the Salamaua–Lae campaign. Throughout the first half of 1943, Australian forces had clashed with the Japanese around Wau and then Mubo as they had pushed the Japanese back towards Salamaua. As the campaign had developed, the Japanese had brought in reinforcements from elsewhere in New Guinea, effectively reducing their garrison, particularly around Lae. Following fighting on Lababia Ridge, the Australians had begun securing positions around Bobdubi, with a view to extending towards Mount Tambu.
