This number 364 in the Osprey Campaign series is similar to most. It provides a good overview of what was a very complex campaign covering the most strategic of the islands in the Dutch East Indies. The map below shows just how methodical the Japanese plans were.

Above all it was a conquest for oil, rubber and other natural resources, but above all for oil.

Imperial Japan’s campaigns of conquest in late 1941/early 1942 were launched in order to achieve self-sufficiency for the Japanese people, chiefly in the precious commodity of oil. The Netherlands (or Dutch) East Indies formed one of Japan’s primary targets, on account of its abundant rubber plantations and oilfields.
The Japanese despatched an enormous naval task force to support the amphibious landings over the vast terrain of the Netherlands East Indies. The combined-arms offensive was divided into three groups: western, centre and eastern. The isolated airfields and oilfields were, however, picked off one by one by the Japanese, in the rush to secure the major islands before major Allied reinforcements arrived.
I enjoyed reading this Campaign book. I had very narrow knowledge of the overall campaign and the publication provided me with enough of an overview for me to fill the gaps.
The NEI forces were hampered by a conquered homeland and with major allies that had different strategic objectives than they had. It as also a very one sided affair with Dutch using outmoded tactical doctrine and equipment and an Order of battle that consisted of large numbers of locally raised troops who were not interested in supporting the Dutch. In short it was a modern well equipped, well lead and well motivated force against a disaffected Militia.

Like all militia forces some fought very bravely and others did not. An Australian military observer commented that “the Dutch will indeed fight but they do not have the training to be effective” (my paraphrase).
The book is excellent for what it purports to be (an introduction to the campaign) and it is well worth the money. If you are after a detailed commentary this is not the purchase for you. Let me know if you find one as I have been unable to.
I’m in agreement with you, Dave, it’s a very useful book! 🙂 I’ve never found a more detailed reference either. The Osprey title on Japanese airborne forces is quite good for the operations they carried out from what I remember, but those are just very small snapshots from the campaign overall.
John there is this one, but unfortunately it is far too pricey at AU$388.00!
