September 1942 - A victory at last
By the end of the summer of 1942, Australia teetered on the brink of collapse. Their armed forces had endured months of gruelling front line combat against roughly half of the IJA and had lost ground steadily. Due to the sparse population and infrastructure across much of central Australia the population centres were concentrated on the east coast and had fallen some time ago. As the savage battles with the advancing Japanese forces whittled away the reserve of servigeable men there seemed little hope that occupation could be avoided.
Persia was in a similar predicament. They had not fought quite so long, but their army was never as strong as the Australian forces and had been in equally vicious battles. In addition, the impact of constant Japanese bombing raids against British postitions had caused untold damage to Persian infrstructure during the long fighting retreat westwards. The British were already withdrawing the bulk of the Persian army to defend new lines in Iraq, abandoning their unfortunate puppet to its fate.
Eliminating even the furthest-flung and most isolated enemy states had proven an arduous task, but Imperial planning staff had never doubted that it was possible. The bulk of their efforts were currently expended on the vast, swirling triphibious war in the Pacific. There could be no hope of eliminating the threat of american raids at the source, and so a strategy of containment and counterstrike soaked up more and more scarce resources.
In particular, lack of transport fleets remained the single biggest limiting factor on operations. Reserves of combat troops still seemed more than adequate. In order to mount a fresh Pacific offensive on any scale, the IJN needed to gather all available transports, and withdrawing them from Australian waters was the order of the day. General Higashikuni received word that he had little time left to use the ships while advancing northwest of Adelaide...
Increased transport activity in waters not thoroughly cleared caused some embarassment, with a small Australian cruiser group scattering one convoy.
Such incidents were minor inconveniences, however, and were coming less and less often. Soon the laboriously coordinated counterstrikes were driving home, bringing sighs of relief in Japan!
The perceived need to bring the British (and if possible the americans) to the negotiating table in late 1942 had one direct cause: Concern at the highest levels of the Imperial government that the Soviet Union was winning it's war with Germany.
Although no dramatic breakthroughs had occurred on this front for months, the balance of forces favoured the Red Army in such a test of strength. An entire bureau in Tokyo was occupied computing day by day the predicted date of German collapse. If Japan were still to be occupied with its current foes when Stalin got peace it would be a disaster.
If for no other reason than the questionable politics of some Japanese allies...
