The Bougainville campaign was a series of land and naval battles of the Pacific campaign of World War II between Allied forces and the Empire of Japan, named after the island of Bougainville. It was part of Operation Cartwheel, the Allied grand strategy in the South Pacific.
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 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 Landings at Cape Torokina, also known as Operation Cherryblossom, took place at the beginning of the Bougainville campaign in World War II. The amphibious landings were carried out by elements of the United States Marine Corps in November 1943 on Bougainville Island in the South Pacific, as part of Allied efforts to advance towards the main Japanese base around Rabaul under Operation Cartwheel. Coming in the wake of Allied successes at Guadalcanal and in the central Solomons, the landings were intended to secure a beachhead with the purpose of establishing several bases from which to project air and naval power closer towards Rabaul, in an effort to neutralize the large Japanese force that had been established there.
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 Battle of the Koromokina Lagoon was fought between the United States Marine Corps and Imperial Japanese Army forces on Bougainville Island. It took place on 7–8 November 1943 during the Bougainville campaign of the Pacific War.
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 1st New Guinea Infantry Battalion was a battalion of the Australian Army during World War II. One of four infantry battalions raised in New Guinea, 1 NGIB was formed in March 1944. In late 1944, the battalion began deploying company-sized elements in support of combat operations on Bougainville, New Britain and on mainland New Guinea. It later became part of the Pacific Islands Regiment before being disbanded in June 1946.
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 2/9th 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.
Farida Force was the name given to an ad hoc composite Australian Army unit formed during World War II. Largely consisting of Australian commandos, the force was established for the purpose for conducting an amphibious landing at Dove Bay, east of Wewak during the Aitape-Wewak campaign. Coming ashore in mid-May 1945, the force quickly established a beachhead and pushed inland, cutting the Wewak road. Afterwards, the commandos conducted patrolling operations before Farida Force was dissolved and its constituent units placed under the command of the 19th Brigade for further operations around Wewak.
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 2/11th 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 Borneo campaign in 1945. As a part of this campaign the squadron undertook landings on Labuan Island and at Brunei Bay. Following the end of the war, the squadron returned to Australia and was disbanded in early 1946.
The Battle of Porton Plantation took place near the village of Soraken on Bougainville Island, in the Solomon Islands archipelago during World War II. Involving forces from Australia, New Zealand and Japan, the battle was part of the wider Bougainville campaign, which had begun in late 1943 and lasted until the end of the war in August 1945. The battle formed part of Australian efforts to liberate the northern part of Bougainville.
The Battle of Pearl Ridge was an engagement of the Second World War fought between Australian and Japanese forces on Bougainville Island. Part of the wider Bougainville Campaign, the battle took place in the central sector of the island, shortly after the Australians had taken over responsibility from the Americans. Believing that the ridge was held by less than a company of Japanese, on 30 December the Australian 25th Infantry Battalion launched a four-pronged attacked the ridge. The defending force, however, had been greatly reinforced by elements of the 38th Independent Mixed Brigade and was closer to a battalion in strength. After being held up on the right of their advance, the Australians dug in overnight and repulsed a strong Japanese counterattack before resuming the attack on 31 December. By late in the afternoon, the Japanese had been swept off the ridge. The Australians later established an observation post on the ridge, which had commanding views of the whole island, and throughout the remainder of the campaign used it to control artillery fire as they advanced towards Japanese enclaves in the north and south of the island.
The Battle of the Hongorai River took place during the Second World War and involved Australian, New Zealand and Japanese forces. Part of the wider Bougainville Campaign of the Pacific theatre, the battle was fought in the southern sector of Bougainville Island. Coming after the Battle of Slater's Knoll in which a strong Japanese counterattack was defeated, the battle occurred in two distinct periods between 17 April and 22 May 1945, as elements of the Australian 15th Brigade advanced south along the Buin Road.
The Landing at Jacquinot Bay was an Allied amphibious operation undertaken on 4 November 1944 during the New Britain Campaign of World War II. The landing was conducted as part of a change in responsibility for Allied operations on New Britain. The Australian 5th Division, under Major General Alan Ramsay, took over from the US 40th Infantry Division, which was needed for operations in the Philippines. The purpose of the operation was to establish a logistics base at Jacquinot Bay on the south coast of New Britain to support the 5th Division's planned operations near the major Japanese garrison at Rabaul.
The Battle of Ratsua occurred during the Second World War and involved Australian and Japanese forces. Part of the wider Bougainville Campaign of the Pacific theatre, the battle took place in the northern sector of Bougainville between June and August 1945. The main forces that took part in the fighting were the Australian 23rd Brigade and the Japanese 87th Naval Garrison Force.
The 2/11th Field Regiment was an Australian Army artillery regiment formed as part of the Second Australian Imperial Force during World War II. Formed in Victoria in mid-1940, the regiment was deployed to the Middle East in 1941 and subsequently took part in the fighting against the Vichy French in the Syria–Lebanon Campaign. In early 1942, they were brought back to Australia in response to Japan's entry into the war, and in 1943 joined the garrison in Darwin. Throughout 1944–45, the regiment was deployed to New Guinea before supporting the 3rd Division's campaign on Bougainville. After the war, the regiment was disbanded.
