The 9th Division was a division of the Australian Army that served during World War II. It was the fourth division raised for the Second Australian Imperial Force. The distinctions of the division include it being:
The Borneo campaign of 1945 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 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, mopping-up operations 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 name commando has been applied to a variety of Australian special forces and light infantry units that have been formed since 1941–42. The first Australian "commando" units were formed during the Second World War, where they mainly performed reconnaissance and long-range patrol roles during Australia's campaigns in New Guinea and Borneo, although other units such as M and Z Special Units performed more clandestine roles. These units were disbanded following the end of the war; however, in the 1950s it was realised that there was a need for such units again in the Australian forces. Today, the Australian Army possesses a number of units that perform more conventional direct-action type commando roles, as well as counter-terrorism response, long-range patrolling, and clandestine deep-penetration operations.
The Battle of North Borneo took place during the Second World War between Allied and Japanese forces. Part of the wider Borneo campaign of the Pacific War, it was fought between 10 June and 15 August 1945 in North Borneo. The battle involved a series of amphibious landings by Australian forces on various points on the mainland around Brunei Bay and upon islands situated around the bay. Japanese opposition to the landings was sporadic initially, although as the campaign progressed a number of considerable clashes occurred and both sides suffered significant casualties, although major combat was largely restricted to Labuan and around Beaufort. On the mainland, while Allied conventional operations focused largely on the coastal areas around Brunei Bay, guerrilla forces consisting of Dayak tribesmen and small numbers of Allied personnel from the Services Reconnaissance Department fought an unconventional campaign in the interior. The Allies were successful in seizing control of the region. Nevertheless, many of the strategic gains that possession of North Borneo provided were ultimately negated by the sudden conclusion of the war in August 1945.
The 2/6th Cavalry Commando Regiment was a cavalry regiment of the Australian Army that served during the Second World War and was later converted into a commando unit. Formed at Ingleburn, New South Wales, in November 1939, it was originally raised as an armoured reconnaissance regiment attached to the 6th Division. In that role, the 2/6th saw action in the North Africa campaign and in the Middle East during 1940–41, where the regiment distinguished itself at Bardia, Tobruk and in Syria. Later, following Japan's entry into the war, the 6th Division was brought back to Australia and following a re-organisation, the regiment was converted into a cavalry commando regiment, incorporating the independent companies that had been formed at the start of the war. In late 1944, the 2/6th Cavalry Commando Regiment was deployed to New Guinea, where it participated in one of the final Australian campaigns of the war in the Aitape–Wewak area.
The Battle of Labuan was an engagement fought between Allied and Imperial Japanese forces on the island of Labuan off Borneo during June 1945. It formed part of the Australian invasion of North Borneo, and was initiated by the Allied forces as part of a plan to capture the Brunei Bay area and develop it into a base to support future offensives.
The 2/4th Commando Squadron was one of 12 independent companies and commando squadrons raised by the Australian Army during the Second World War. Raised in August 1941, it was disbanded not long after due to conceptual problems, but it was quickly reformed following the entry of Japan into the war in December 1941. After a period of about six months performing garrison duties in northern Australia, the 2/4th was deployed to Portuguese Timor to reinforce the other Australian units already waging a guerilla war on the island. After a brief campaign the 2/4th was returned to Australia and from there it went on to serve in New Guinea in 1943, taking part in the Salamaua-Lae campaign attached to the 9th Division. Later, the squadron was involved in one of the last campaigns of the war when it landed on Tarakan Island in May 1945 and took part in the Borneo campaign. Following the end of hostilities, the 2/4th returned to Australia and was disbanded at Ingleburn, New South Wales, on 8 January 1946.
The 2/5th Commando Squadron was one of twelve independent companies and or commando squadrons of the Australian Army formed for service during World War II. Initially formed in 1942 as the "2/5th Independent Company", the 2/5th served in New Guinea, taking part in a major commando raid on Salamaua in June 1942. It was later withdrawn from New Guinea and reformed as the "2/5th Cavalry (Commando) Squadron", as part of the 2/7th Cavalry (Commando) Regiment which saw service in Borneo in 1945. It was disbanded in early 1946.
The 2/6th Commando Squadron was one of 12 independent companies or commando squadrons raised by the Australian Army during the Second World War. Raised in May 1942 as the 2/6th Independent Company, the 2/6th's main role was to conduct irregular type warfare including small scale raiding, sabotage, long-range patrolling and reconnaissance operations rather than the traditional commando type direct action operations. As such, for the most part the unit conducted operations in small groups operating inside enemy territory, or out in front of larger friendly forces. Between 1942 and 1945, the 2/6th undertook four major campaigns during the war—Kokoda, Buna, Markham–Ramu and Borneo—and was involved in arguably one of the most spectacular small unit actions of the war during the Battle of Kaiapit. The unit was disbanded in January 1946, following the cessation of hostilities in the Pacific.
The 2/3rd Commando Squadron was one of twelve independent or commando companies and squadrons formed by the Australian Army for service during World War II. Raised in October 1941 as the 2/3rd Independent Company, it served in New Caledonia and New Guinea before being amalgamated into the 2/7th Cavalry Commando Regiment and adopting the name 2/3rd Commando Squadron in 1943. After this, the squadron did not see action again until 1945, when it participated in the Borneo campaign. Throughout the course of the war, the 2/3rd lost 69 members killed in action. No battle honours were awarded to the unit, although it participated in a number of notable engagements in these campaigns and its members received numerous decorations for their service. Following the end of hostilities in the Pacific, the unit was disbanded in early 1946, upon their return to Australia.
The 2/7th Commando Company was one of 12 independent companies or commando squadrons raised by the Australian Army during the Second World War. Raised in May 1942, as the 2/7th Independent Company, the 2/7th served in New Guinea in 1943 during the Salamaua–Lae campaign before being redesignated as the 2/7th Commando Squadron when it was amalgamated with two other commando squadrons to become part of the 2/6th Cavalry (Commando) Regiment. Later at the end of 1944, it was sent to New Guinea again, where it took part in the Aitape–Wewak campaign. Following the end of the war, the squadron was returned to Australia and disbanded early in 1946.
The 2/7th Cavalry (Commando) Regiment was one of three commando regiments raised by the Australian Army for service during World War II. It was originally raised as the 7th Division Cavalry Regiment in 1940 and in this guise it served in North Africa and the Middle East at the beginning of the war, before it was brought back to Australia and sent to New Guinea in late 1942 to serve against the Japanese. In mid-1943 the Australian high command decided to disband the divisional cavalry regiments and use their headquarters elements to administer the independent companies that had been raised earlier in the war. In the process the 7th Division Cavalry Regiment disbanded its squadrons, gave up their vehicles and changed its name to the 2/7th Cavalry (Commando) Regiment, as it became the administrative headquarters for the 2/3rd, 2/5th and 2/6th Commando Squadrons.
The 2/9th Cavalry (Commando) Regiment was one of three commando regiments raised by the Australian Army for service during World War II. It was originally raised in 1940 as an armoured cavalry unit as part of the 8th Division, before being transferred to the 9th Division. Between 1941 and 1942 the regiment saw action in the Middle East before being returned to Australia in early 1943. At this time the regiment was re-organised as the administrative headquarters for the 2/4th, 2/11th and 2/12th Commando Squadrons and it was converted into a commando regiment. Later in 1945 the unit saw action during the landings on Tarakan on Borneo before being disbanded upon the cessation of hostilities.
The 2/9th Commando Squadron was a commando unit raised by the Australian Army for service in World War II. Raised in 1944, the unit saw action late in the war against the Japanese during the Aitape–Wewak campaign taking part in number of long range patrol operations across the Torricelli Range in New Guinea before being used in an amphibious landing near Wewak in May 1945. After the war the unit was disbanded.
The 2/10th Commando Squadron was a commando unit raised by the Australian Army for service in World War II. Raised in 1944, the unit saw action late in the war against the Japanese during the Aitape–Wewak campaign. During this campaign the squadron carried out a number of tasks including long-range patrols, flank protection and area defence. Later in the campaign the 2/10th were used to spearhead an amphibious assault landing at Dove Bay, east of Wewak before being used as line infantry during the final 'mopping up' stages of the campaign. Following the end of the war the unit was disbanded.
The 2/12th Commando Squadron was a commando unit raised by the Australian Army for service in World War II. Raised in 1944 following a re-organisation of Australia's military forces, the unit participated in the Borneo campaign in 1945 but played only a limited role before hostilities ended. Following the end of the war, the squadron returned to Australia and was disbanded in early 1946.
The 24th Brigade was a brigade-sized infantry unit of the Australian Army. Formed on 1 July 1940 as part of the Second Australian Imperial Force, the unit was raised for service during World War II. Originally formed as part of the 8th Australian Division the brigade was subsequently transferred to the newly created 9th Australian Division in December. The brigade served during the Western Desert Campaign, forming part of the Allied garrison during the Siege of Tobruk. Later, the brigade was withdrawn to Syria for occupation duties, but then later took part in the First and Second Battles of El Alamein. In early 1943, the brigade was returned to Australia to fight against the Japanese in the Pacific. In 1943–1944, the brigade fought in New Guinea, taking part in the landing at Lae and the Huon Peninsula campaign. Its final campaign came late in the war, when it took part in the Labuan landings and the Battle of North Borneo in mid-1945. After the war, the brigade was disbanded in early 1946.
The 2/43rd Battalion was an infantry battalion of the Australian Army. Raised in July 1940 in South Australia as part of the 24th Brigade, the battalion was initially part of the 8th Division, until the 24th Brigade was re-allocated to the 9th Division in late 1940. It was with this formation that the 2/43rd saw service in the Middle East in 1941–1942, taking part in the fighting at Tobruk and in the First and Second Battles of El Alamein. It also undertook garrison duties in Syria, before returning to Australia early in 1943 to fight against the Japanese in the Pacific.
The Battle of Beaufort took place during the Second World War between Allied and Japanese forces. Part of the wider Borneo campaign of the Pacific War, it was fought between 26 and 28 June 1945 in North Borneo. The battle formed part of the Allied efforts to secure North Borneo in the final months of the war and saw two Australian infantry battalions attack the town, which was held by a force of around 800 – 1,000 Japanese. Over the course of several days heavy fighting took place before the Japanese began withdrawing on 29 June. While withdrawing, the Japanese were ambushed and suffered heavy casualties.
