Early April 1942
Some thoughts on the strategic situation.
With the fall of Singapore and Clark Field, the equivalents of 4 Japanese divisions has been freed for other tasks. The Singapore units will assist in the capture of Java. I already have two divisions ashore on Java together with support units and a mixed brigade. What remains in the NEI for me to capture is Balikpapan, Java, Makassar and the northern bases on Sumatra. After Java, all of these bases can be cleared with SNLF-type units.
I have one regiment and three SNLF units at Koepang, these are immideately avaliable for deployment.
After the fall of Port Moresby, I have one division and four infantry regiments avaliable for operations. These units are at Port Moresby.
By now Darwin is prepared for war, and presumably heavily reinforced. Im expecting at least 200 AV at the base, and more coming along the roads north. 18th UK Div has not been spotted so far, and they could be anywhere. But since our operations in Burma are going at a snails-pace, I doubt he has reinforced that theater. I also dont think he is reinforcing Ceylon since the KB has not made any moves in that direction. It is reasonable to assume that the 18th is in Australia.
The US and UK carriers remain a wildcard, they have not been spotted since the outbreak of hostilities. Force Z also remains at large somewhere out there. I doubt the CVs are in the Darwin area, due to the proximity of Betty- and Zero-bases, but I fully expect that Force Z is in or around Darwin. One possible location for the CVs are around Exmouth, from there they can strike at any landing on the northern coast while still being able to retreat easily.
Gentlemen, I give you operation Spotlight, the offensive against Australia.
Initial landings will take place on the Australian east coast. A force of one division and three infantry regiments will land with the objective of cutting the railline between southern and northern Australia. This force will be the roadblock. The landings will hopefully force my opponent to shift his forces from the Darwin area to the northeast coast.
After these landings, the northern operations will commence. The northern invasion will take place somewhere between 1-3 weeks after the initial landings. The forces in the northern sector will consist of forces from Java and the Philipines.
Reinforcements are currently being gathered at Port Arthur and consists of several Tank regiments, engineers and cavalry units, well suited to the mobile warfare in Australia. These units will either land at Darwin or on the east coast, depending on how things are going on the respective front.
KB will cover the eastern landings, the northern landings will have to make due with land-based aircover only. Mini-KB will be sent deep into the shipping lanes of the Indian Ocean in an effort to intercept reinforcements from India.
