The military service records of Willy Erkelens provide a fascinating insight into the international wartime and postwar networks that connected the Netherlands East Indies (NEI), Australia, the United States and Indonesia during and after the Second World War.
His career reflects the experiences of many Dutch military personnel who escaped the collapse of the NEI in 1942 and became part of the Allied wartime aviation system that developed across the Pacific region. The records from Bronbeek also demonstrate the important role Australia — particularly Brisbane and Wacol — played in Dutch military reorganisation during the war and in the years immediately afterwards.
Stories such as that of Willy Erkelens help illustrate the broader shared wartime heritage linking Australia, the Netherlands and Indonesia.
Early life in the Netherlands East Indies
Willy Erkelens was born in Batavia on 30 November 1919. His service records describe him as a trained technician who completed MULO education, attended Dick de Hoogeschool and undertook three years of technical schooling.
Before the outbreak of war in the Pacific he entered military service in the colonial armed forces of the Netherlands East Indies.
On 1 July 1941 he enlisted as a militia soldier and entered active service for military training. Soon afterwards he became involved in aviation-related instruction.
The records show that on 1 November 1941 he became a military sergeant second class and commenced pilot training.
Only weeks later, on 5 December 1941, he married Eveline Jeane Josine Puts in Bandung, shortly before the Pacific War spread across Southeast Asia. The couple later had children including Peggy, William and Roy.
Escape to Australia
Unlike many Dutch servicemen who became prisoners of war following the Japanese invasion, Erkelens escaped the collapsing Netherlands East Indies and became part of the Dutch wartime aviation rebuilding effort overseas.
The records show that on 18 February 1942 he departed for Australia. By 1 March 1942 he had arrived there and was incorporated into Dutch military aviation structures operating from Australia.
Following the collapse of the NEI, Australia rapidly became a major refuge and operational base for Dutch military and civilian organisations. Brisbane in particular emerged as a critical Allied command and logistics centre in the Southwest Pacific.
Camp Columbia at Wacol, Brisbane became closely associated with the Netherlands East Indies Government-in-Exile after the Dutch took over sections of the former American military complex in 1944. The broader Wacol area contained accommodation camps, military administration, training facilities and aviation-related activities connected to Dutch Army, Navy and Air Force personnel.
Allied aviation training in America
One of the most significant aspects of the records is Erkelens’ extensive aviation training in the United States.
On 18 April 1942 he departed for America and on 8 May 1942 he was attached to the Royal Netherlands Military Flying School (RNMFS) at Jackson, Mississippi.
The RNMFS was one of the most important Dutch wartime aviation institutions established outside occupied Dutch territory. Supported by the United States Army Air Forces, it trained Dutch pilots and aviation personnel for Allied operations during the war.
The records document a broad range of specialised aviation training, including:
- pilot training;
- radio-telegraphist training;
- aerial gunnery;
- parachutist qualifications;
- military observer training.
He also trained at Panama City, Florida, including at Gunnery School No. 6.
These entries demonstrate how Dutch wartime aviation became deeply integrated into wider Allied aviation systems after the collapse of the Netherlands East Indies.
Return to Australia and 120 Squadron
On 9 August 1943 Erkelens departed the strength of the RNMFS and returned to Australia.
This period coincided with the rapid expansion of Dutch wartime activities centred around Brisbane and Wacol. Dutch military aviation personnel moved through Australian training and operational facilities while the Dutch attempted to rebuild military capability after the destruction of their forces in Southeast Asia.
One of the most historically significant entries in the file records that on 1 August 1945 Erkelens was transferred to 120 Squadron NEI RAAF at Biak, Dutch New Guinea.
No. 120 (Netherlands East Indies) Squadron represented one of the most important Dutch–Australian wartime aviation collaborations. The fighter squadron operated under Royal Australian Air Force command while maintaining Dutch personnel and identity.
Equipped with P-40 Kittyhawk aircraft, the squadron played an active operational role in the Southwest Pacific campaign.
The posting of Erkelens to 120 Squadron directly connects him to this important Allied military cooperation between Australia and the Netherlands.
Postwar Indonesia and the aviation conflict
After the Japanese surrender, Erkelens returned to the Netherlands East Indies during the increasingly unstable postwar period.
The records show that on 1 January 1946 he was attached to Dutch military structures in Bundaberg, Australia, before departing for Batavia on 1 April 1946.
Subsequent postings included:
- Soerabaja (Surabaya);
- Bandung;
- Kalidjati airbase.
These assignments occurred during the Indonesian War of Independence, when Dutch military personnel became involved in efforts to restore Dutch authority following Indonesia’s declaration of independence in August 1945.
The significance of Erkelens’ wartime career therefore extends beyond Australia.
His name also appears in the DACC article “Foreign pilots, Dutch blockades and the Indonesian air war: the Jogja Incident of 29 July 1947.” This places him within the wider military aviation operations connected to the Indonesian conflict.
After WWII the Dutch attempted to re-establish colonial authority in Indonesia, while Indonesian nationalists fought for independence. Aviation became a key component of Dutch military operations during this conflict.
The inclusion of Erkelens within this broader history highlights how many Dutch servicemen connected to Australia later became involved in the difficult and controversial transition from colonial rule to Indonesian independence.
Wacol and postwar aviation training
The records also reveal a continuing connection between Erkelens and Wacol.
On 22 November 1949 he received instructor qualifications connected to P.C. Wacol and the AT-16 training aircraft.
The AT-16 was the Dutch designation for the North American AT-6 Texan advanced trainer aircraft, widely used in postwar pilot training.
This reference further highlights the continuing importance of Queensland and Wacol within Dutch military aviation networks after WWII.
Decorations and distinctions
The service records contain numerous references to aviation qualifications and military decorations.
These include:
- Klein Militair Vliegbrevet;
- military observer qualification;
- parachutist brevet;
- aerial gunner qualification.
Most notably, on 9 December 1949 Erkelens was awarded the Dutch Vliegerkruis (Flying Cross), a distinguished military aviation decoration recognising courage, perseverance and skill during operational flying service.
The records also note that he received the Oorlogsherinneringskruis (War Memorial Cross) connected to wartime service.
The end of the KNIL era
One handwritten note records that Erkelens later returned to the Netherlands and was honourably discharged following the abolition of the KNIL:
“Wegens opheffing KNIL met goed verlof.”
This brief entry reflects a major historical transition.
The KNIL — the Royal Netherlands East Indies Army — had existed for more than a century as the colonial military force of the Dutch East Indies. Following Indonesian independence, the KNIL was formally dissolved in 1950.
For many Dutch servicemen, this marked the end not only of military careers but also of an entire colonial world that disappeared during and after WWII.
A shared Dutch–Australian wartime history
The military service records of Willy Erkelens demonstrate the highly international nature of Dutch wartime history.
His career connected the Netherlands East Indies, Australia, America, New Guinea and postwar Indonesia through Allied aviation networks that emerged during WWII.
For the Dutch Australian Cultural Centre, stories such as these help reconstruct the broader Dutch wartime presence in Australia and the close military cooperation that developed between Australia and the Netherlands during the Pacific War.
They also reinforce the important role played by Brisbane and Wacol within these international wartime and postwar networks.
A young Dutch technician in Batavia
Willy Erkelens was born in Batavia (now Jakarta) on 30 November 1919. According to his military service record, he was a Dutch national who trained as a technician. His education included MULO studies and three years at technical school.
Like many young men in the Netherlands East Indies before the Second World War, Erkelens entered military service at a time of growing instability in the Pacific region. The Japanese advance through Southeast Asia would soon overturn the entire colonial structure of the NEI.
His file records that on 8 December 1941 — immediately after the outbreak of war in the Pacific — he was mobilised as a militia soldier first class.
Only three months later, on 8 March 1942, the Dutch East Indies capitulated to Japan.
Return to Dutch military service
After liberation, Erkelens resumed military service within the reconstituted Dutch forces.
The record shows that he was assigned to the L.O.C. and later transferred to staff functions connected with the A Division in Soerabaja (Surabaya). He departed for Batavia on 6 October 1946 during the increasingly unstable postwar period in Indonesia.
Like many former POWs, Erkelens returned directly from wartime suffering into a new conflict environment. The Indonesian Republic had proclaimed independence in August 1945, while the Netherlands attempted to restore colonial authority. The result was a prolonged and bitter decolonisation struggle.
Military aviation and Australian connections
One of the most interesting aspects of the service record is Erkelens’ strong connection to military aviation.
Before the Japanese invasion he had already qualified for the Klein Militair Vliegbrevet (small military flying brevet) on 1 November 1941. During the war years and immediately afterwards he obtained further aviation-related qualifications, including military observer and machine-gunner certifications.
The Australian connection becomes particularly important in a later entry from 28 November 1949, which records that Erkelens became an instructor responsible for physical training at P.C. Wacol connected to the AT-16 training aircraft.
This links him directly to the Dutch military presence in wartime and postwar Brisbane.
During the Second World War, Camp Columbia at Wacol became one of the major Allied military complexes in Queensland. Initially constructed for the United States Army, the camp later became closely associated with the Netherlands East Indies Government-in-Exile after the Dutch took over parts of the complex in 1944.
The broader Wacol area contained military camps, training facilities, accommodation centres and aviation-related activities involving Dutch Army, Navy and Air Force personnel.
The AT-16 referred to in the file was the Dutch designation for the North American AT-6 Texan advanced trainer aircraft. These aircraft became important in rebuilding Dutch military aviation capability after the war.
The record therefore places Erkelens within the Dutch aviation training structure linked to Queensland during the immediate postwar years.
The Indonesian air war and the Jogja Incident
The historical significance of Willy Erkelens expands further through his appearance in the DACC article “Foreign pilots, Dutch blockades and the Indonesian air war: the Jogja Incident of 29 July 1947.”
That article examines the increasingly international character of the Indonesian conflict, particularly the use of military aviation during Dutch operations against the Indonesian Republic.
Following the end of WWII, Dutch forces attempted to regain control over the former Netherlands East Indies. Air power became a central component in reconnaissance, transport, blockade enforcement and military operations.
The conflict rapidly developed international dimensions, attracting foreign pilots, political controversy and growing diplomatic pressure against the Netherlands.
The connection between Erkelens and this broader aviation history demonstrates how Dutch servicemen who had survived Japanese captivity often became directly involved in the violent and politically divisive decolonisation struggle that followed the war.
It also highlights the transitional role of Australia — particularly Brisbane and Wacol — as a military and logistical hub linking the Allied war against Japan with the postwar conflict in Indonesia.
Decorations and later service
The record notes several military qualifications and distinctions earned by Erkelens during and after the war.
Most notably, on 9 December 1949 he was awarded the Vliegerkruis (Flying Cross), one of the Netherlands’ distinguished military aviation decorations. The award recognised courage, perseverance and skill demonstrated during operational flying duties.
The file also records his marriage to Eveline Jeane Josine Puts in Bandoeng (Bandung) on 5 December 1941 — only days before the Pacific War erupted across Southeast Asia. The couple later had two children, William and Roy.
These personal details provide a reminder that behind the official military entries stood families whose lives were repeatedly disrupted by war, displacement and political upheaval.
A shared Dutch–Australian–Indonesian history
The military service record of Willy Erkelens encapsulates several interconnected histories: the collapse of the Netherlands East Indies in 1942, Japanese captivity, the Dutch wartime presence in Australia, the rebuilding of military aviation in Queensland, and the violent transition from colonial rule to Indonesian independence.
For the Dutch Australian Cultural Centre, records such as these are valuable historical sources because they help reconstruct the complex wartime and postwar connections between Australia, the Netherlands and Indonesia.
They also reinforce the importance of places such as Camp Columbia and Wacol in understanding Brisbane’s role as a major Allied and Dutch military centre during and after the Second World War.
