Old Faithful on the Secret Frontier: The 3rd Battalion Royal Australian Regiment in the Borneo Confrontation 1965

Part I: The Unwanted War – Australia’s Path to Borneo

Chapter 1: Konfrontasi – The Geopolitical Crucible

The conflict known as the Indonesia-Malaysia Confrontation, or Konfrontasi, was an undeclared war fought between 1963 and 1966, rooted in the complex geopolitics of post-colonial Southeast Asia.1 Its origins lay in Indonesia’s strident opposition to the formation of the Federation of Malaysia. This new state, formally established in September 1963, was a British-engineered merger of the already independent Federation of Malaya with the British Crown colonies of Singapore, North Borneo (later Sabah), and Sarawak.1

For Indonesian President Sukarno, the creation of Malaysia represented a direct threat to his regional ambitions and a continuation of Western colonial influence. He framed the federation as a “neo-colonial” plot by the “Old Established Forces” of the West, designed to encircle Indonesia and stymie its emergence as a dominant regional power.3 This opposition was multifaceted. Ideologically, it clashed with Sukarno’s vision of a “Greater Indonesia” (Indonesia Raya), which some proponents believed should naturally encompass the Malay-populated territories of Borneo.5 Domestically,

Konfrontasi served as a powerful tool for Sukarno to unify the disparate and often antagonistic political factions within his nation—including the powerful Indonesian Communist Party (PKI) and the military—against a common external enemy. By stoking a low-level international crisis, he could distract from pressing domestic economic problems and consolidate his fragile political position.2

The nature of this “undeclared war” was deliberately ambiguous. Sukarno’s policy was not one of conventional, state-on-state warfare, which would have risked a disastrous, full-scale conflict with Great Britain and its Commonwealth allies. Instead, as Indonesian Foreign Minister Subandrio first articulated in January 1963, it was a policy of “confrontation”.2 This was a carefully calibrated strategy, a “nebulous mix of coercive activity” short of all-out war, encompassing aggressive political rhetoric, diplomatic pressure, economic warfare, and, most significantly, a campaign of low-intensity military action.1 The initial phase of this military campaign was marked by the Indonesia-backed Brunei Revolt in December 1962. Though quickly suppressed by British and Gurkha troops dispatched from Singapore, the revolt signaled the start of hostilities.1 Following its failure, Indonesia began to train and support the North Kalimantan National Army (TNKU) and commenced a campaign of cross-border infiltrations into Sarawak and Sabah.1 These incursions were initially conducted by so-called “volunteers” and irregulars, often Indonesian Army troops disguised as local insurgents, who conducted sabotage, spread propaganda, and mounted raids on police stations and security force outposts.2

This calculated ambiguity presented a significant strategic challenge for the Commonwealth. Sukarno’s use of deniable incursions and proxies allowed him to apply consistent military pressure on the nascent Malaysian state without providing the clear casus belli that would justify a conventional, escalatory response. The Commonwealth was thus faced with the dilemma of how to effectively counter this aggression and defend a 1,450-kilometre jungle frontier without triggering a major regional war.2 This strategic paradox, born from the politically motivated and deliberately undeclared nature of

Konfrontasi, would ultimately necessitate an equally clandestine and carefully controlled response, setting the stage for the secret cross-border operations that would come to define the conflict.

The Confrontation was also an episode of the Cold War in Asia. While Malaysia received direct military support from the United Kingdom, Australia, and New Zealand, Indonesia was backed indirectly by the Soviet Union and China, who provided military and economic aid.1 For the Western powers, defending Malaysia was not merely about honoring a treaty obligation; it was about containing the perceived spread of communism and pro-communist influence in a strategically vital region.2

Chapter 2: A Calculated Reluctance – Australia’s Graduated Response

The Australian government under Prime Minister Sir Robert Menzies greeted the outbreak of hostilities in Borneo with profound caution and a deep-seated reluctance to become militarily involved.2 This was not a reflection of indifference to Malaysia’s security, but a sober calculation of Australia’s own strategic vulnerabilities. The primary concern was the long and largely indefensible border between the Australian-administered Territory of Papua and New Guinea and Indonesian West Irian.2 A direct military conflict with Indonesia, a nation of 100 million people, risked igniting a second front that Australia lacked the resources to defend. Furthermore, Australian foreign policy at the time was still in the process of reorienting towards Southeast Asia, and antagonizing its largest and most powerful neighbour was seen as contrary to long-term national interests.2

Consequently, Australia’s initial response to British and Malaysian requests for assistance was one of carefully graduated commitment, designed to support the Commonwealth effort while avoiding direct combat with Indonesian forces. Initial support was limited to providing military supplies and training for the expanding Malaysian armed forces.2 This was followed in April 1964 by a more tangible, yet still non-combatant, contribution: the deployment of a Royal Australian Engineers construction squadron to Borneo to work on infrastructure projects and two Royal Australian Navy minesweepers to patrol coastal waters.4 A more significant step was the agreement to allow Australian forces stationed in Malaysia as part of the Far East Strategic Reserve (FESR) to be used in the defense of Peninsular Malaysia from any direct Indonesian attack.2 This commitment, however, explicitly excluded their deployment to Borneo.

The event that shattered this policy of containment occurred in September and October 1964. In a significant escalation, Indonesia launched a series of overt attacks on the Malaysian mainland itself. These took the form of a seaborne landing of around 100 troops near Pontian in Johore, followed by an airborne drop of paratroopers near Labis.4 These incursions represented a fundamental strategic miscalculation by Indonesia. While the strategy in Borneo had relied on the deniability afforded by the remote jungle terrain, these landings were undeniable acts of aggression against the Malaysian heartland. Militarily, they were a failure; the infiltrators, expecting to be greeted as liberators, were swiftly contained and either killed or captured by British, Malaysian, and New Zealand forces.2

Crucially, elements of the 3rd Battalion, Royal Australian Regiment (3RAR), which was based at Camp Terendak in Malacca as part of the FESR, were deployed in the “mopping-up” operations against these landings.4 This marked the first involvement of Australian infantry in the conflict. The political fallout was decisive. By bringing the war directly to the Peninsula, Indonesia had crossed a strategic red line for the Australian government. The attacks demonstrated that

Konfrontasi was not a containable border dispute but a genuine threat to regional stability that could escalate further.2 The argument for keeping Australian combat troops out of Borneo was no longer tenable. Following a direct request from the Malaysian government, Canberra relented. In January 1965, the Menzies government announced that it would deploy an infantry battalion to Borneo.4 The unit selected for this task was the battle-hardened 3RAR. Indonesia’s attempt to escalate the conflict on its own terms had backfired, triggering the very commitment of elite Commonwealth combat forces it had sought to avoid.

Chapter 3: A Battalion Forged in Fire – The Provenance of 3RAR

The decision to deploy the 3rd Battalion, Royal Australian Regiment, to Borneo was a commitment of one of the Australian Army’s most seasoned and capable units. Nicknamed “Old Faithful” for its continuous service from the beginning to the end of the Korean War, 3RAR possessed a formidable combat pedigree that made it uniquely suited for the complex demands of the Borneo campaign.13 The battalion’s subsequent tactical dominance in Sarawak was not a matter of chance; it was the direct result of a decade-long accumulation of diverse combat experience and specialized training.

The battalion’s character was forged in the high-intensity conventional warfare of the Korean War (1950-1953). Rapidly committed from occupation duties in Japan, 3RAR formed a key part of the 27th Commonwealth Brigade.13 It distinguished itself in a series of major engagements, from the initial UN offensive into North Korea, including the Battle of Chongju in October 1950, to the desperate defensive battles against massive Chinese offensives.13 The battalion’s epic stand during the Battle of Kapyong in April 1951, where it helped halt a major Chinese push towards Seoul, earned it the prestigious United States Presidential Unit Citation.13 Its performance in the Battle of Maryang San in October 1951 is widely regarded as one of the Australian Army’s finest achievements of the war.13 This experience in Korea instilled in the battalion a deep-seated discipline, resilience under fire, and a high degree of proficiency in combined-arms operations.

Following Korea, 3RAR underwent a second, equally formative experience during its first tour of the Malayan Emergency from 1957 to 1959.11 Here, the nature of combat was entirely different. Instead of conventional battles, the battalion was engaged in a protracted counter-insurgency campaign against communist terrorists in the dense jungle.11 This tour honed a different set of skills: patience, meticulous patrolling, ambush techniques, and the subtle arts of jungle fieldcraft.11 The battalion learned to operate for extended periods in small, isolated groups, mastering the challenges of navigation, tracking, and survival in an unforgiving environment.

These two distinct operational experiences were underpinned by a rigorous and highly specialized training doctrine. The Australian Army, drawing on its experiences in the Pacific during the Second World War, had established the Jungle Training Centre at Canungra, Queensland, in 1942.20 Re-established in 1954 to prepare units for service in Southeast Asia, Canungra became the crucible for Australian jungle warfare expertise.20 The training was notoriously demanding, consisting of weeks of physical and mental hardening through punishing obstacle and confidence courses, realistic battle inoculation with live ammunition, and intensive instruction in minor tactics, navigation, and fieldcraft.20 This system formalized the lessons of past campaigns into a repeatable doctrine, ensuring that every soldier and officer was prepared for the specific challenges of jungle combat.

The synthesis of these three elements—the conventional warfare discipline of Korea, the counter-insurgency expertise of Malaya, and the specialized doctrinal training of Canungra—created a battalion of exceptional quality. When 3RAR was warned for deployment to Borneo, it was a unit that possessed the resilience of a conventional army, the fieldcraft of a counter-insurgency force, and a deep, institutionalized understanding of jungle warfare. Its subsequent success was the predictable outcome of this unique and comprehensive preparation, marking it as one of the most effective light infantry battalions in the world for that specific mission.

Chapter 4: Deployment to the Bau Salient

The 3rd Battalion, Royal Australian Regiment, arrived in Borneo in March 1965, transitioning directly from its role in the Far East Strategic Reserve in Malacca to the front line of the Confrontation.4 On 22 March 1965, the battalion formally relieved the 1/7th Duke of Edinburgh’s Own Gurkha Rifles in the Bau district of western Sarawak, immediately integrating into the complex Commonwealth command structure.12 This handover from a veteran Gurkha unit to an experienced Australian battalion exemplified the high degree of interoperability that characterized the Commonwealth forces in Borneo.

Command of the battalion rested with Lieutenant Colonel Bruce McDonald.12 Operationally, 3RAR was placed under the command of the British-led West Brigade, which held the critical responsibility for defending the western portion of Sarawak, including the key approaches to the capital, Kuching, located just 50 kilometres from the border.12 The battalion’s area of operations was a salient of Malaysian territory jutting into Indonesian Kalimantan, a region of strategic importance and a frequent target for Indonesian incursions.

The battalion’s disposition was carefully planned to establish a comprehensive defensive screen along the frontier. Battalion Headquarters, along with the reserve company (D Company), was established at a central base in the town of Bau.12 From here, the battalion’s three remaining rifle companies were pushed forward to occupy a series of fortified company bases along the border. A Company was deployed to Stass in the west, B Company to Bukit Knuckle in the centre, and C Company to Serikin in the east.12 Each of these forward bases was responsible for a sector of the border approximately 7 kilometres wide and was situated about 1,500 meters from the frontier itself.9 This forward-leaning posture was designed not merely to defend Malaysian territory, but to dominate the border area, providing early warning of Indonesian movements and creating a layered cordon through which any infiltrators would have to pass.24

Chapter 5: The Jungle Craft

The operational environment that confronted 3RAR in Borneo was one of the most challenging on earth. The battlespace consisted of towering, jungle-clad mountains, deep ravines, and swampy valleys, all under a debilitating tropical climate of intense heat and near-constant humidity.1 A near-total lack of roads or railways meant that all movement was restricted to arduous foot patrols along narrow jungle tracks or via rivers.1 It was in this environment that the Commonwealth forces perfected a unique and highly effective system of jungle warfare.

The core of this system was the principle of dominating the jungle through relentless and aggressive patrolling. Operations were characterized by long-range foot patrols, typically lasting five to ten days, that radiated out from the fortified company bases.1 The operational tempo was high; at any given time, each forward company typically had two of its three platoons out on patrol while the third remained in the base, with the platoons rotating every four days.9 These patrols were not random sweeps but meticulously planned missions of reconnaissance and ambush, designed to intercept Indonesian forces moving through the jungle.22

This system of dominance was enabled by two critical factors: sophisticated logistics and superior intelligence. With the forward bases completely isolated from road networks, resupply was entirely dependent on air assets.9 Royal Air Force helicopters, such as the Belvedere and the commando-carrying Wessex, were the workhorses of the campaign, ferrying troops into patrol areas and delivering vital supplies of food, water, and ammunition.2 Where helicopter landing zones were unavailable, supplies were delivered by air drop from RAF transport aircraft.9 This ability to sustain forces deep in the jungle for extended periods gave the Commonwealth a decisive operational advantage.

Intelligence was the second key enabler. A sophisticated Signals Intelligence (SIGINT) effort provided crucial information on Indonesian movements and intentions.12 This was complemented at the tactical level by invaluable human intelligence. Each Australian company was assigned indigenous Iban trackers from the Sarawak Rangers, whose innate jungle skills and local knowledge were indispensable for tracking enemy movement and detecting signs of their presence.9

The combination of these elements—constant patrolling, aerial resupply, and multi-sourced intelligence—created a system of attrition that was won not primarily through direct combat, but through establishing suffocating dominance over the border region. While the major firefights were tactically significant, they were also relatively rare.23 The true effectiveness of the Commonwealth strategy, executed with precision by units like 3RAR, lay in the thousands of patrol-hours that created an environment of constant threat for the Indonesians. This relentless pressure forced Indonesian units to become reactive, compelling them to remain on the defensive on their own side of the border and expend their resources protecting their own bases rather than launching incursions into Sarawak. The victory was being won not just in the ambushes, but in the grueling, unseen work that prevented many more from ever occurring.

Part III: The Secret War – Operation Claret

Chapter 6: Seizing the Initiative

By mid-1964, the Commonwealth military leadership in Borneo recognized that a purely defensive strategy, confined to the Malaysian side of the border, was insufficient to defeat the Indonesian campaign of infiltration. The Director of Borneo Operations (DOBOPS), Major General Walter Walker, a veteran of the Burma and Malaya campaigns, concluded that to win, Commonwealth forces had to seize the initiative.6 The result was Operation Claret, a series of highly classified, deniable cross-border operations into Indonesian Kalimantan, authorized with the agreement of the British and Malaysian governments in July 1964.9 The strategic purpose of Claret was to take the fight to the enemy, forcing the Indonesians onto the defensive in their own territory, disrupting their supply lines, and gathering intelligence to preempt their attacks on Sarawak and Sabah.2

To manage the immense political risks associated with these violations of Indonesian sovereignty, General Walker instituted a strict set of “Golden Rules” that governed every Claret mission.28 These rules were a masterclass in controlled escalation. Every operation required personal authorization from DOBOPS. Only highly trained and experienced troops, initially just Gurkhas and Special Forces, were permitted to participate.28 Penetration into Kalimantan was initially limited to 5,000 yards, though this was later extended to 10,000 and then 20,000 yards as the campaign progressed.28 Attacks were only to be conducted to thwart impending enemy offensive action, not as retribution. Crucially, operations had to be deniable: soldiers wore no identification, carried no items that could trace them back to their units, and were under strict orders to leave no prisoners or casualties, alive or dead, behind in Indonesian territory.2

The need for deniability fostered an environment of extreme secrecy. The existence of Claret operations was not publicly acknowledged by the British government until 1974, and by Australia not until 1996.2 This secrecy permeated every level of the campaign. A dual-reporting system was often employed, where an official, sanitized patrol report was filed showing the unit operating within Malaysia, while a second, true report detailing the cross-border action was passed up the operational chain of command.36 Soldiers were sworn to secrecy and were often forbidden from discussing their missions even with other platoons in their own company.36 This pervasive secrecy was the primary reason that Australia’s significant involvement in the Confrontation became known as the “Forgotten War”.2 During its four-month tour, 3RAR conducted a total of 32 Claret operations, ranging from reconnaissance patrols to platoon-strength ambushes.18

The Claret framework was more than just a set of operational guidelines; it was a sophisticated tool of escalation dominance. By strictly controlling the depth, scale, and objectives of the raids, and by maintaining absolute deniability, the Commonwealth could inflict tactically significant and disproportionate casualties on the Indonesians, disrupting their campaign at the operational level. Simultaneously, this secrecy denied President Sukarno the political ammunition—the undeniable proof of a full-scale invasion—that he would have needed to justify escalating the conflict to a conventional war at the strategic level. The Indonesians knew they were being attacked in Kalimantan but could not prove it to the world. This allowed the Commonwealth to dominate the conflict, punishing aggression while simultaneously preventing a wider war, and in doing so, exacerbated the internal pressures that would ultimately contribute to the downfall of Sukarno’s Konfrontasi policy.

Chapter 7: The Battle of Sungei Koemba (27 May – 12 June 1965)

The series of ambushes conducted by 3RAR along the Sungei Koemba river in May and June 1965 stand as textbook examples of the tactical effectiveness of Claret operations. These engagements demonstrated the battalion’s superior fieldcraft, discipline, and firepower, resulting in decisive victories deep inside Indonesian territory.

The first ambush, on 27 May 1965, was conducted by a composite force of two platoons from B Company, commanded by the company commander, Major William Broderick.12 After crossing the border, the patrol established an ambush position overlooking a bend in the Sungei Koemba. At 11:32 am, two motorized 10-foot boats, each carrying five uniformed and armed Indonesian soldiers, came into view.12 The Australians held their fire until the boats were just 35 meters away before opening up with a devastating volley of automatic fire. The first boat sank immediately, and the second drifted downstream; all occupants were killed.12 As two more enemy boats rounded the bend, Private Lawrence Jackson engaged the third boat from a range of only 10 meters, killing all five occupants before his weapon jammed. The fourth boat pulled to the bank, and Jackson engaged it with grenades.12 Under heavy return fire from Indonesians on the opposite bank, Major Broderick ordered a clean break, and the patrol withdrew under the cover of pre-planned defensive artillery fire, recrossing the border without suffering any casualties. At least 15 Indonesians were confirmed killed, with Indonesian radio later reporting 23 soldiers “accidentally killed” during a training exercise.12 For their actions, Lieutenant Patrick Beale, one of the platoon commanders, was awarded the Military Cross, and Private Jackson received the Military Medal.12

A fortnight later, on 12 June 1965, 3RAR struck again. This time, a platoon from C Company, led by the company commander Major Ivor Hodgkinson, established an ambush further downstream on the same river.12 At 10:45 am, an Indonesian foot patrol was detected moving along the riverbank. The Australians initiated the ambush, killing four Indonesians in the opening seconds. As the remainder of the enemy patrol advanced, they were engaged by Major Hodgkinson and the platoon commander, Lieutenant Robert Guest, who led a counter-attack. The brief, violent action left a further four Indonesians dead. The Australians collected enemy weapons and equipment, identifying the dead as belonging to the Indonesian 440 Battalion.12 Once again, the patrol withdrew successfully under the cover of artillery fire without sustaining any casualties. Eight Indonesian soldiers were killed and one was seriously wounded.12 For his decisive leadership, Major Hodgkinson was appointed a Member of the Order of the British Empire (MBE).12 These two engagements on the Sungei Koemba demonstrated 3RAR’s mastery of riverine ambush tactics and its seamless coordination with supporting artillery, allowing the battalion to project lethal force across the border with impunity.

Chapter 8: The Kindau Ambush – A Classic Engagement (15 June 1965)

Just three days after the second successful ambush on the Sungei Koemba, A Company of 3RAR executed what has been described as a “classic ambush,” further cementing the battalion’s dominance in its area of operations.26 Codenamed Operation Blockbuster, the mission was a direct response to intelligence indicating increased Indonesian use of an east-west track inside Kalimantan, southwest of the A Company base at Stass. The objective was to intercept a large Indonesian force believed to be returning to its base after infiltrating Sarawak.26

On 12 June, a 30-man platoon from A Company, commanded by Second Lieutenant Douglas Byers and accompanied by an artillery Forward Observation party, crossed the border.26 They moved 1,300 meters into Indonesian territory and established a meticulously planned ambush position in thick, swampy jungle astride the target track. The platoon lay in silent, cold ambush for three full days, a testament to their extraordinary discipline and fieldcraft.26 At 13:26 on 15 June, their patience was rewarded. A large Indonesian force, estimated at between 50 and 100 men, was observed approaching. The soldiers were well-equipped with modern AR-15 Armalite rifles and US steel helmets.26

Byers waited until approximately 25 Indonesians had entered the killing ground before initiating the ambush with his Owen submachine gun. The opening volley, combined with Claymore mines triggered by the cut-off party, was devastating, killing at least 15 enemy soldiers instantly.26 The surviving Indonesians, though surprised, reacted quickly, returning fire with machine guns, mortars, and grenades. A fierce firefight ensued, during which the outnumbered Australians silenced the enemy machine gun. As the battle raged, the Australian forward observer called in highly accurate and effective artillery fire from 105mm and 5.5-inch guns located back in Sarawak. The artillery barrage suppressed the Indonesian mortars and caught a larger follow-on force, inflicting further heavy casualties.26 By 13:45, Byers gave the order to withdraw. The platoon successfully broke contact, carrying one soldier who had been wounded in the knee and assisting another wounded in the thigh by shrapnel.26

The Battle of Kindau was a resounding Australian victory. While two Australians were wounded, total Indonesian losses were estimated to be as high as 50 killed, largely due to the lethality of the supporting artillery.26 The operation, however, led to a rare breach of Claret’s secrecy. A journalist managed to interview one of the wounded Australians in a hospital in Singapore, forcing the military authorities to issue a public statement that maintained the fiction that the engagement had occurred on the Malaysian side of the border.26 For his “skillful conduct” and leadership, Second Lieutenant Douglas Byers was awarded the Military Cross.26

Part IV: The Human Dimension and the Conclusion of the Tour

Chapter 9: Comrades and Casualties

The Borneo Confrontation was a quintessential Commonwealth campaign, characterized by a high degree of seamless cooperation between the armed forces of Britain, Australia, New Zealand, Malaysia, and the Gurkhas of Nepal. 3RAR’s experience was a microcosm of this interoperability. The battalion operated within a British command structure as part of West Brigade, alongside British and Gurkha units.2 They relieved a Gurkha battalion upon their arrival and were in turn relieved by a Malay regiment at the end of their tour.12 Logistical and aviation support was provided primarily by Britain’s Royal Air Force, whose helicopters were the lifeline for the forward company bases.2 Artillery support was also integrated; the Australian 102nd Field Battery, for instance, provided fire support not only for 3RAR but also for British Guards, Parachute, and Gurkha regiments during their respective operations.22 This close integration was built on a foundation of shared doctrine, training, and operational procedures, allowing diverse national contingents to function as a single, cohesive fighting force.

Despite the battalion’s tactical successes and the disproportionate casualties inflicted on the enemy, 3RAR’s tour was not without cost. During its four months in Borneo, the battalion suffered three soldiers killed and five wounded.11 In a poignant reflection of the nature of the conflict, all three fatalities were the result of enemy-laid landmines, not from direct firefights.11 This highlighted the insidious and ever-present threat of booby traps and mines on jungle tracks, which could turn a routine patrol into a tragedy in an instant. The first casualty of the tour occurred on 3RAR’s very first day of operations, 23 March 1965, when Sergeant Reginald “Reno” Weiland was killed instantly by an M2A3 anti-personnel mine while leading a reconnaissance patrol near the company base at Stass.25 In another incident, Private Larry Richard Downes was killed when he stepped on a “jumping jack” mine; a fragment from the same mine also killed his acting platoon commander, Sergeant Vince Vella.39 These losses underscored the constant danger of the jungle environment, where the enemy was often unseen.

The bravery and exceptional leadership displayed by members of the battalion during the intense Claret operations were formally recognized with a number of gallantry awards. For their leadership and courage during the successful ambushes, Lieutenant Patrick Beale and Second Lieutenant Douglas Byers were both awarded the Military Cross.32 For his decisive actions during the first Sungei Koemba ambush, Private Lawrence Jackson was awarded the Military Medal.12 In recognition of his command and leadership during the second Sungei Koemba action, Major Ivor Hodgkinson was appointed a Member of the Order of the British Empire (MBE).12 These awards provided official testament to the skill and valor demonstrated by 3RAR at all ranks during its secret war across the border.

Chapter 10: Withdrawal and the End of Confrontation

After four months of intense and highly successful operations, the 3rd Battalion’s tour of duty in Borneo came to an end. On 28 July 1965, 3RAR handed over its area of responsibility in the Bau salient and returned to its main base at Terendak Camp in Malacca.17 The battalion remained in Malaysia as part of the Far East Strategic Reserve for several more months before departing for Australia in October 1965.23

The immediate impact of the battalion’s operations, particularly its aggressive execution of the Claret missions, was significant and measurable. The series of successful ambushes in May, June, and July inflicted substantial casualties on Indonesian forces and shattered their sense of security in their own rear areas.4 This allowed 3RAR to effectively dominate the border region, providing crucial early warning of potential incursions and severely disrupting Indonesian operational capacity. A clear indicator of this success was the marked decrease in Indonesian activity opposite the 3RAR sector following these engagements. Notably, the frequent and heavy mortar attacks that had characterized the early part of the tour ceased almost entirely after the Kindau ambush.26 By keeping the Indonesians off-balance and preoccupied with their own force protection, 3RAR contributed directly to the wider Commonwealth strategic goal of neutralizing the Indonesian military threat in Borneo.

The military pressure exerted by Commonwealth forces, exemplified by the performance of units like 3RAR, was a key factor contributing to the eventual end of the Confrontation. This military stalemate, combined with the severe economic strain the conflict was placing on Indonesia, exacerbated internal political tensions in Jakarta.2 The tipping point came in the wake of an attempted coup by communist sympathizers on 30 September 1965. The coup’s failure led to a bloody anti-communist purge and the decisive transfer of power from President Sukarno to the anti-communist General Suharto.6 Suharto, a pragmatist, recognized that

Konfrontasi was a costly and unwinnable war. He moved swiftly to end the conflict, and on 11 August 1966, Indonesia and Malaysia signed a peace treaty in Bangkok, formally bringing the undeclared war to a close.2

Part V: Legacy of a Secret War

Chapter 11: The Forgotten War

The strategic necessity for secrecy that ensured the tactical success of Operation Claret also cast a long shadow over the soldiers who fought it, creating a complex and difficult legacy. The very tool that allowed 3RAR to dominate the battlefield also served to isolate its veterans from the society they served, denying them the public acknowledgment that is a crucial component of a soldier’s return from war. For decades, their conflict was not just forgotten, but officially non-existent in its most vital aspects.

The most direct consequence for the veterans was the burden of secrecy imposed by the British Official Secrets Act, which remained in force for 30 years after the conflict.36 This gag order prevented soldiers from speaking about their most significant and traumatic experiences, even to their families or to each other.36 This enforced silence created a distorted collective memory of the war, even among its participants. Many veterans interviewed decades later recalled believing that their platoon was the only one to have conducted cross-border operations, unaware that it was a standard, albeit secret, practice across the battalion.36 This isolation was compounded by the knowledge that official records were deliberately falsified to maintain deniability, effectively erasing their true service from the historical record.36

This official secrecy contributed to the Confrontation becoming a “forgotten war” in the Australian national narrative.32 The conflict was completely overshadowed by the simultaneous and rapidly escalating commitment to the Vietnam War, which dominated media coverage and public debate.32 The lack of press reporting from Borneo, a direct result of the sensitive and clandestine nature of the operations, meant that the public remained largely unaware of the fighting and the sacrifices being made.32 This has resulted in a lasting gap in public consciousness, with the history of Australia’s post-war military commitments often jumping from Korea directly to Vietnam, bypassing Borneo entirely.36

This lack of public awareness has fuelled a long and frustrating struggle by veterans and their families for official recognition. Despite the service of over 3,500 Australians and the loss of 23 lives, there is no dedicated national memorial to the Confrontation on Anzac Parade in Canberra.7 Veterans have expressed deep disappointment over the failure of official bodies to provide even small tokens of recognition, such as a commemorative postage stamp.36 For many aging veterans, there is a palpable sense that time is running out to have their service properly acknowledged and remembered.36 While academic research has begun to shed light on the psychological costs of war for veterans of the Confrontation, the unique burden of carrying the secrets of a clandestine war, coupled with a profound lack of societal validation, represents a hidden cost that is only now beginning to be understood.41

Chapter 12: Conclusion – An Assessment of 3RAR’s Performance

The performance of the 3rd Battalion, Royal Australian Regiment, during its 1965 tour of duty in Borneo represents a model of tactical and operational excellence in a complex, low-intensity conflict. The battalion’s actions in the Bau salient demonstrated the decisive effectiveness of a highly trained, combat-experienced, and superbly led light infantry unit operating in one of the world’s most demanding military environments. The consistent success of its patrols and the devastating outcomes of its major cross-border ambushes stand as a testament to the professionalism and skill of the Australian soldier.4

3RAR’s deployment made a significant and direct contribution to the overall Commonwealth victory in the Confrontation. By aggressively dominating its sector of the border through relentless patrolling and the judicious application of lethal force during the Claret operations, the battalion successfully neutralized the Indonesian threat in its area of responsibility.4 This performance supported the wider strategic goal of seizing the initiative from the Indonesians, forcing them onto the defensive, and ultimately contributing to the military stalemate that helped precipitate the political changes in Jakarta that ended the war.

Within the history of the Royal Australian Regiment, the Borneo deployment holds a place of particular importance. It served as a crucial bridge, allowing the regiment to apply the hard-won counter-insurgency lessons of the Malayan Emergency and further refine them in a more conventional, albeit clandestine, setting before their large-scale application in the Vietnam War.2 The experience in Borneo solidified the RAR’s reputation for mastery of jungle warfare and reinforced its identity as a professional, combat-ready force capable of operating with discipline and lethality across the spectrum of conflict.17 However, the legacy of 3RAR’s service in Borneo is a dual one. While it stands as a case study in military effectiveness, it is also a poignant reminder of the long-term human cost of “secret wars,” where the very policies that ensure victory on the battlefield can impose a decades-long burden of silence and a struggle for recognition on the veterans who fought and won it.
