Brief summary of Dutch – Australian cooperation

More by default than through thorough planning the Dutch and Australian were thrown into the war in SE Asia together with other allies such as the Brits and Americans against an incredibly rapid expanding Japanese occupation of SE Asia. Through this essay the military activities are further detailed in their relevant chapters. But as we are talking about a war situation it is important to provide this brief overview of some of the key combined military activities.

Lat us first start with the diplomatic contacts which started when it became clear that the Japanese started its own war in SE Asia.

The attack on Peal Harbour (7 December 1941) and the consequent development changed the situation and active military collaboration started. This is a brief overview of the key military  actions that followed.

  • The Battle of Singapore (8-15 February 1942) and other events in the SE Asia war theatre in February 1942 saw Dutch and Australians fighting side by side.
  • The fight on land against the Japanese in NEI in February and early March 1942, where Australians and Dutch fought again side by side, left many Australian soldiers stranded, many of them ended up in the infamous Burma Camps. Many Australians blamed the Dutch for this.
  • The war continued on the islands in the Arafura See and  on Dutch New Guinea throughout 1942 and 1943, however most of the war effort of the Allies was done by ship, these were often easy targets for the far superior Japanese air force. 
  • The south eastern part of Dutch New Guinea was never occupied by the Japanese and the Allies were able to built an important port and airfield in Merauke.
  • To a large extend thanks to the Dutch Merchant Fleet, who brought in the equipment, supplies and troops, the battle at Milne Bay (PNG) – operation  ‘Lilliput’ was the first one where the Japanese were defeated.
  • A combined military activity in Timor in late 1942 failed however it was the largest resistance fight of the Dutch and Australian military against the Japanese on NEI and again delayed further advances which contributed to the eventual defeat of the Japanese in the South Pacific  in 1944
  • Sharing of Australian military facilities with the members of the exiled KNIL (Koninklijk Nederlands Indisch Leger – The Royal Netherlands East Indies Army).
  • Establishing four combined air squadrons, three army battalions and adding 19 ships to the naval fleet.
  • Provided most of the NEI intelligence services for the Allied Forces.
  • Australians had the largest Allied force in the unoccupied part of South Dutch New Guinea and fought with the Americans in the north of the island and successfully ousted the Japanese. Control was handed over to the Dutch in 1945.
  • The secret operation of the Australian Z-Force[1] to ‘kidnap’ the pro-Dutch Sultan of Ternate in 1945.
  • Australian military together with the British Army took over control of NEI, after the capitulation of Japan, they eventually handed over control to the Dutch in 1946.
