After the surrender of Netherlands East Indies to the Japanese, it was the intention of the commander of the ML-KNIL General van Oyen to establish a NEI Squadron using the various aircraft and air crew who were now at Archerfield, Brisbane this included Dutch technical personnel who had been able to evacuate to Australia. Collaboration with the RAAF led a few months later to the formation of a combined squadron.
With a heavily under resourced KNIL (NEI army), van Oyen made sure that he had significant control over the formation of a Dutch squadron. He was very well connected in the Australian influential social circles, which assisted him in making the right connections to achieve his goal.
The 80 ML-KNIL members from Archerfield together with members of the RAAF now formed the 18 Netherlands East Indies Squadron/RAAF, based in Canberra, as the Archerfield airport had become too busy and therefore not suitable for training purposes. These airmen were divided into several operational groups under RAAF control. All their stores and equipment were supplied by the American Armed Forces and paid for by the Dutch. On 18 June 1942, the total number of staff of 18 Squadron consisted of 206 Australians and 242 Dutch/NEI servicemen.
Whilst stationed at Fairbairn, Canberra, the squadron undertook anti-submarine patrols along the New South Wales coastline. Gus Winkel sunk a submarine is Sydney Harbour in the early part of the war when they were doing anti-submarine patrols.
After their training in Canberra, the Squadron relocated to McDonald Airfield in the Northern Territory, with the first operational mission on 18 January 1943. Logistically, McDonald airfield was too far away from intended targets so fully laden bombed up B-25’s were forced to land in Darwin specifically to refuel. A few months later the Squadron relocated again, to Batchelor NT and remained there until the squadron relocated finally to Balikpapan in 1945 at the end of WWII. Here they were under the overall command of the No.79 Wing RAAF.
No.79 Wing RAAF
|No. 79 Wing was a Royal Australian Air Force (RAAF) wing of World War II. It was formed in December 1943 at Batchelor, Northern Territory, as part of North-Western Area Command. Led by Group Captain Charles Eaton, the wing comprised four squadrons on its establishment, the Nos. 1 and 2 Squadrons RAAF (flying Beaufort light reconnaissance bombers), No. 31 Squadron RAAF (Beaufighter long-range fighters), and No. 18 (Netherlands East Indies) Squadron (B-25 Mitchell medium bombers).
No. 79 Wing took part in the New Guinea and North-Western Area Campaigns during 1944–45, eventually transferring to Balikpapan in the Dutch East Indies as the Allies advanced northward. By the end of the Pacific War, the wing was attached to the Australian First Tactical Air Force and was made up of Nos. 2 and 18 (Netherlands East Indies) Squadrons, both flying Mitchells. The latter transferred to the Netherlands Air Force in late 1945, while the former returned to Australia where it disbanded the following year. No. 79 Headquarters itself disbanded in October 1945, soon after the end of hostilities. (Source: Wikipedia)
The squadron was now brought to full strength with the arrival of more RAAF personnel and consisted of 40 officers and 210 men from the ML-KNIL and 8 officers and 300 men from the RAAF.
The B-25s however, did have some severe shortcomings. The reach of the planes was only just enough to fly a bombing mission to NEI. Several planes crash landed when they ran out of fuel. After many casualties and arguments Commander Fiedeldij, put it bluntly, they would not fly anymore unless they received the necessary modifications. This worked and the RAAF agreed that the planes were sent to Eagle Farm in Brisbane where they received a 300-gallon bomb bay drop tank and more and heavier calibre weapons.
They were involved in many actions across NEI and were able to show the Dutch war effort to the people in NEI. They destroyed many Japanese operations on NEI, sunk 6 Japanese ships and numerous smaller boats. These men really were amazing, they did low level bombing of shipping. That means they were just above mast height when they were attacking Japanese shipping.
More air force personnel were becoming available from the Dutch pilot training school in Jackson, USA. This allowed the Dutch, who wanted to increase the 18th, with two more squadron. The Americans agreed to deliver the pre-ordered (and pre-paid) B-25s if the Dutch were able to provide sufficient personnel. This also required additional ground personnel and this needed to be provided by the Australians. The Australians wanted this to be led by the RAAF and were keen to lay their hands on the extra planes. However, the Americans supported the Dutch and Australia eventually agreed to provide 600 to 700 staff. This was under the provision that under the White Australia Policy, only white staff would be allowed to man the squadrons. The Dutch were able to start the 2nd squadron in May 1943.
In that year under a similar arrangement between the Dutch and Australian military command a second squadron was installed, named 120 NEI Squadron RAAF. This squadron moved from Canberra to Merauke in the southern part of Dutch New Guinea – the only unoccupied territory in NEI.
Both the 18 and the 120 Squadrons were also involved in the Western Australian Emergency in March 1944.
There is an interesting story from B 25 Commander Hans de Vries.
As the war progressed, the B-25’s he and his colleagues were flying were progressively modified for the specialist attacks they were undertaking. ‘Skip Bombing’ was found to be the most effective technique against enemy shipping. The technique had been perfected in New Guinea, against an old wreck off Port Moresby. The concept of ‘skip-bombing’ was a low, flat approach to drop bombs short of the target in such a way that the bombs bounced off the water and struck nose first against the hull or superstructure of the target ship, where they detonated. The major disadvantage was heavy fire from the target; attacking low and fast meant there was no margin for error or mishap. The early B-25s lacked sufficient forward firing armament to suppress this fire. Later versions of nearly all Mitchells featured local modifications to increase the number of fixed forward firing .50 cal machine guns. As many as eight could be controlled by the pilot and co-pilot.
The planes remained operational until 1950, when the equipment from the squadron was handed over to the Indonesian Airforce.
