Australia in the Indonesia–Malaysia confrontation

In early 1963 the Indonesian Government adopted a policy of destabilising and ultimately breaking up Malaysia, which was to become independent of the United Kingdom in September 1963. Small parties of Indonesian Army troops disguised as Malaysian insurgents were infiltrated into Malaysian territory in Borneo to spread propaganda and conduct sabotage during 1963, and several major raids were conducted against Malaysian Army and security forces bases. More attacks were conducted in 1964, with the Indonesians expanding the conflict by openly employing regular Army units and conducting raids in peninsular Malaysia. These attacks raised the risk of a general war between Malaysia and Indonesia. During the early 1960s Australian military units were based in Malaysia as part of the Far East Strategic Reserve and whilst Australian units had participated in the Malayan Emergency between 1948 and 1960, the Australian Government was reluctant to become involved in fighting with Indonesia. This was due at least in part to a fear that any such fighting would spread to the long and indefensible border between Indonesia and the Australian-administered Territory of Papua and New Guinea. Accordingly, several requests from the British government during 1963 and 1964 to deploy forces to Borneo were rejected. ==Ground operations==

Peninsular Malaysia 1964 by Australian troops. Although not initially agreeing to send troops to Borneo, in April 1964 the Australian Government agreed to allow its forces to be used to protect peninsular Malaysia from attack, whilst also announcing that it would dispatch an engineer construction squadron to Borneo, while also providing two naval mine-sweepers, four helicopters and other support in addition to units already stationed in Malaysia. Meanwhile, in June the 111th Light Anti-Aircraft Battery deployed to Butterworth in northern Malaysia to defend the airfield in case the Indonesians conducted an unexpected air raid. The 3rd Battalion, Royal Australian Regiment (3 RAR), which was based at Camp Terendak in Malacca, was subsequently used to mop up two small airborne and seaborne landings near Labis and Pontian in September and October 1964. These incursions seemed to suggest a serious escalation in the conflict was imminent. Units arrived in Borneo in early 1965. 1 Squadron, Special Air Service Regiment (SASR) arrived in February and was followed by 3 RAR in March. Engineer units were also deployed to Borneo where they conducted field engineering and construction tasks, whilst artillery was also deployed. The Malaysian Government later requested a second Australian battalion, however this was declined as the army lacked the resources needed for such a deployment. The battalion manned defensive positions and conducted patrols to detect infiltration parties. 3 RAR also conducted 32 secret 'Claret' operations in which one or two platoon-strong parties entered Indonesian territory to ambush Indonesian forces. The battalion had four major contacts with Indonesian forces and many smaller ones—including two major ambushes on the Sungei Koemba river, another at Kindau and again at Babang between May and July—with all ending in success. These operations inflicted significant casualties on Indonesian forces and allowed 3 RAR to dominate the border area, as well as providing early warning of incursions into Sarawak and contributing to the wider success of the British-Commonwealth forces in slowly asserting control on the war. 3 RAR completed its tour in August 1965 and returned to Camp Terendak. The battalion suffered three men killed in action in two separate land mine incidents during its time in Borneo. The 4th Battalion, Royal Australian Regiment (4 RAR) arrived in Malaysia in September 1965 to replace 3 RAR, which returned to Australia in October. After a period of training the battalion deployed to Sarawak in April 1966 where it was to operate from four company bases in the Bau area. By this time the war was winding down as peace negotiations had begun between Malaysia and Indonesia. Like 3 RAR, 4 RAR conducted cross-border operations and clashed with Indonesian forces on a number of occasions. Its tour was less eventful, however, and the battalion primarily operated in Malaysian territory where it ambushed tracks leading from the border with Indonesia. Malaysia and Indonesia agreed to a peace treaty on 11 August and 4 RAR and the other Commonwealth units in Borneo ceased operations the next day. The battalion returned to Camp Terendak on 30 August having suffered five fatalities in Borneo, though only one man had been killed in action. They suffered their first fatality on 2 June when Lance-Corporal Paul Denehey was gored by an elephant. 2 Squadron arrived in Borneo in January 1966 for a four-month deployment, and despite the suspension of Claret operations it also conducted reconnaissance patrols and cross-border operations, undertaking a total of 45 patrols on both sides of the border until being withdrawn in July. Two members of the squadron drowned while trying to cross a river during a patrol on 20–21 March. SASR patrols inflicted significant casualties on the Indonesians throughout the war, even though they were often tasked with covert reconnaissance. New Guinea–Indonesia border In addition to operations in Malaysia, Australian troops patrolled the Indonesia-Papua New Guinea border during the confrontation. These operations were conducted by the Pacific Islands Regiment (PIR), which was an Australian Army formation manned by native New Guineans and led by Australian officers and warrant officers. Although there was only one shooting incident between the PIR and Indonesian troops, a number of incursions took place and these patrols–which were often conducted in rugged terrain–placed considerable demands on Australia's already limited defence resources. The PIR was also expanded from one to two battalions in 1963 in response to the increased threat posed by Indonesia, though a third battalion authorised in 1964 was not formed. Other precautions included the construction and upgrading of a number of airfields in Papua New Guinea for use by the RAAF. ==Naval operations==

The Royal Australian Navy's (RAN's) involvement in the Confrontation also began in 1964. At this time two Australian destroyers or frigates were always in Malaysian waters as part of the FESR and other warships, including the aircraft carrier , made periodic visits. The Australian warships served as part of a fleet of up to eighty warships whose mission was to defeat attempts to infiltrate Indonesian Army units by sea, provide naval gunfire support and prevent piracy. RAN warships undertook coastal patrols in the Malacca Strait, off Singapore and the Tawau-Wallace Bay area off Sabah. The six s of the RAN's 16th Minesweeping Squadron arrived in May 1964 and were particularly successful in these tasks. Minesweeper exchanged fire with an Indonesian vessel near Singapore on 13 December 1964, with the vessel surrendering after three of the seven Indonesians on board were killed. She captured another Indonesian ship carrying nine armed infiltrators in the Malacca Strait on 23 February 1965. was attacked by an Indonesian shore battery while operating within Singapore territorial waters on 13 March 1966. Twelve RAN warships served in Malaysian waters during Australia's involvement in the Confrontation, with several performing more than one tour of duty. One Australian sailor was wounded in action during the Confrontation and two died as a result of sickness or accidents. ==Air operations==

The RAAF was also involved in the Indonesia-Malaysia Confrontation. During the 1960s four Australian flying squadrons were based at RAAF Base Butterworth in Malaysia as part of the FESR. The largest unit was No. 78 Wing RAAF, which comprised the Sabre-equipped No. 3 Squadron and No. 77 Squadron. The other flying units were No. 2 Squadron, which operated Canberra bombers and a small number of Dakota transports, and the UH-1 Iroquois-equipped No. 5 Squadron. No. 78 Wing and No. 2 Squadron had been based at Butterworth since 1958 and No. 5 Squadron arrived in 1964 in response to one of the Malaysian Government's requests for assistance. No. 78 Wing made an important contribution to the defence of Malaysian airspace during the confrontation. It provided two of the three fighter squadrons in Malaysia at the time (the third being a Royal Air Force (RAF) unit equipped with Javelin interceptors based at RAF Tengah) and increased its readiness levels as the Confrontation expanded. On 17 July 1963 Australian Sabres sighted Indonesian Air Force MiG-19s near the Malaysian coast and tracked one of them back towards its base at Medan in North Sumatra. From October 1963 the wing kept two Sabres armed with Sidewinder missiles and cannons on alert at Butterworth during daylight hours. No. 2 Squadron also planned attacks on targets in Java and practiced strikes against Indonesia. Restrictive rules of engagement were initially in place, however, and Indonesian aircraft could only be engaged if they were either declared 'hostile' by the air defence commander or had first attacked a target in Malaysia or Singapore. The landing of paratroopers in Johore during September 1964 caused an increase in tensions. Under 'Plan Addington' RAF V bombers were to be based at RAAF Base Darwin in northern Australia to strike Indonesian aerial facilities if targets in Malaysia were attacked. When the Australian Government became concerned that the parachute landings could lead to open hostilities it ordered the RAAF to deploy 16 Sabres from No. 76 Squadron, which was based RAAF Base Williamtown, to Darwin. The goal of this deployment was to protect Darwin against raids from Indonesian Il-28 bombers in the event of war. An Army anti-aircraft battery was also deployed to Darwin and additional Sabre pilots and ground crew were sent to Butterworth to reinforce No. 78 Wing. The Sabres arrived on 8 September and were maintained at a high level of alert until 17 October. After international tensions eased No. 76 Squadron began returning to Williamstown on 20 October. The rules of engagement for the Australian fighters in Malaysia were loosened as a result of the landing in Johore to allow any Indonesian aircraft which could be positively identified as being within Malaysian or Singapore airspace to be destroyed. RAAF aircraft also supported ground operations during the Confrontation. No. 5 Squadron's activities between 1964 and 1966 included transporting Australian, Malaysian and Singapore troops during operations against Indonesian infiltrators on the Malaysian Peninsular. RAAF aircraft also routinely transported troops and supplies between peninsular Malaysia and Borneo. ==Aftermath==

Following a military coup in Indonesia in early 1966 which brought General Suharto to power Malaysia and Indonesia signed a peace treaty in Bangkok in August 1966, ending the conflict. Official acknowledgement of Australian involvement in Claret missions only occurred in 1996 when Cabinet papers discussing the operations were released. ==Timeline==
