Olorin -> Allies attack Gilberts! Olorin (J) vs NY59Giants (A): A wizzard's guide to Australia (11/10/2012 10:56:07 AM)

Aug 12 The Allies invade the Gilbert Islands with two marine divisions, achieving tactical and operational surprise! The meager garrisons of Tabituea and Abemama fall easily, but Tarawa holds. I have 156 AV there, but supplies were totally expended during the allied shock attack. a lone xAKL was to deliver 1800 tons two days ago, but it was sunk by a sub. 4 DDs that were trying to resupply Tarawa engaged the allied invasion taskforce: quote:

Two destroyers are seriously damaged, one of which is later attacked by dive bombers and is sunk by an allied submarine. In total, three allied taskforces of similar composition to the above one (1 BB, 2 CLs, plus destroyers and transports) support landings at Tarawa, Tabituea and Abemama. The 1st MarDiv is split into three brigades, two of which land at Tarawa and the third one at Abemama. The 2nd MarDiv lands at Tabituea. quote:

It will fall if I don't reinforce it. My reaction: Other than the brief night surface engagement, which happened quite by accident, this offensive came at a good time for the allies. I had a large Mavis unit returned to the home Islands to upgrade to Emilies, so my naval search was lacking. All of my naval search effort was concentrated to the west, leaving considerable gaps to the south. And that's where Michael came from (I suspect Pago-Pago). The IJN 1st Fleet is at Truk (Kido Buttai, plus BatDiv1 with Yamato, Nagato and Mutsu), but Shokaku and Zuikaku are refitting in the HIs, so I have only 4 CVs to contest the landings. I won't intervene. I will let the landings develop and see if it's part of a deeper strategy. I never intended to defend the Gilberts seriously anyway, but I will probably contest further allied expansion to the west (Solomons, Truk, Ponape), as that would jeopardize my SLOCs to Australia. For now, I will try to resupply Tarawa by air and see, using expendable assets. If I manage to hold it, great, if not...well, tough luck. I transfered 27 Betties from Numea to Tulagi, to search the sea between the Solomons and the Gilberts and improved my naval search in the area, but that's about it. Australia The air war escalates in the Australian sky. I sweep Adelaide, Roto, Waga-waga, Sydney in random order to avoid Michael's CAP traps. I get slightly better than 1:1, which is less than I hoped for, but I will continue to attrit the allied airforce. I also use my bombers to attack opportunity targets, such as shipping based at Melbourne. I launched a port strike that sunk 1 sub and several minesweepers and small transports and compelled Michael to leave enough fighters there to defend against my future attacks. Furthermore, after the fall of Broken Hill I begun evacuating the 21st Army from Australia. In a few weeks I will have 3 infantry and 3 armoured divisions as a strategic reserve. The Imperial Division is marching east to join the rest of the 25th Army at Brisbane. Triggered reinforcements: Regarding the issue of the triggered reinforcements for Australia, we contemplated going back to July 11, but since that would include replaying the invasion of Port Augusta, we decided against it. Instead, Michael agreed not to use the new units he got, unless I cross the Brisbane line again.
