On 22th March 1942 Intelligence decrypted information that at least one Japanese unit was loaded on ship and it is moving towards Port Augusta. Japanese carrier group was detected few days earlier, but TF was moving suspiciously slow. Allied HQ expected that enemy will try to attack convoys unloading supplies in Adelaide. But when it didn’t happened all troops were put on alert. 2 US Brigades, artillery unit and tank Battalion from reserves were ordered to move to Port Augusta defended by single Australian Brigade. In Port Augusta heavy cruiser Astoria with escort of 3 DD’s was put on alert and sail away from port to hunt enemies carrier group.
All of this was futile.
On 24th March Astoria TF attacked Japanese convoys but it was destroyed by heavy Japanese naval task force. Even though two DD’s from supporting TF attacked carrier TF, enemy withdraw without scratch.
On the same day Port Augusta was invaded by two divisions.
Allied HQ moved all B-17’s bombers to support defense, but Carrier group providing air cover was hard as rock. Losses among 4E bombers were high and unfortunately enemy was not weakened enough.
On 27th March 1942 Port Augusta fallen and allied troops withdraw to the west (worst option).

Air battle was raging over Port Augusta. Japanese carrier fighter cover is depleted but also allied dive bombers and fighter squadrons.
If the enemy move south he will activate emergency reinforcements that will be used for counteroffensive in Burma. If he will move east there is not to enough land forces to hold him. Also if the Bowen fall Australia will be lost.
In New Zealand additional units are awaiting to move to Australia, but I afraid that they will meet returning carrier force. Or they will not return… Just resupply at newly captured Port Augusta.
Also convoy with planes, marines regiment, and US Army Division sailed away from San Francisco. Protected by US Navy Carriers. They must get to Australia.
