March 22nd to April 4th, 1945
There is no doubt now in my mind that we are fast approaching the terminal stages of this game. Yet, Japan still remains firmly in the fight. Industry in the Home Islands is intact, and while the last dregs of fuel are being consumed, industry pools are sufficient to tide Japan on for quite some time yet.
Philippine Islands
A series of major events transpire here in late-March, with the Allies putting troops ashore in large numbers on Luzon, at Naga in the south of the island.
Japanese efforts to interfere with the landings are shattered by massed B-29 strikes from low altitude at night on Japanese airbases on Luzon. The damage to the plan for the defence of Luzon is catastrophic - the ability to assemble a critical mass of aircraft to seriously damage an invasion fleet is removed, and what strikes that go against the US forces landing are dealt with by a strong CAP supplemented by land-based fighters from bases to the South.
USN carriers swiftly follow this with a raid on Manila, where the four Kongo-class battleships are at anchor, damaging one with a torpedo hit and forcing the battleships to withdraw back to Japan.
The IJN commits the KB to interdicting the US landings on Luzon, but with few land-based squadrons in fighting form after the night airbase raids, there are insufficient aircraft to do serious damage to the US Fleet, and the KB is forced to withdraw after heavy losses in aircraft and pilots. The Japanese carriers do, however, make a clean escape back to Japan.
The outcome of the battle is fairly one-sided. The Allies suffer the loss of two CVE to Japanese aircraft. The battleship USS West Virginia is likely sunk by an IJN submarine. The French battleship Richelieu and the fast battleship Missouri are both damaged, but no damage is inflicted to the USN fast carriers. IJN torpedo bombers on night naval attack missions in the following nights damage a further USN CVE.
Japanese losses are something along the lines of 1,300 planes, mostly on the ground. A large number of squadrons are shattered by these losses and most are pulled back to Formosa to regroup and recover. However, no major warships are lost.
The Allies are now firmly lodged on Luzon, and in force. In repsonse, troops and supplies are being ferried from Formosa to Luzon to help stiffen the resistance, while Japanese fighters on the island fly sweeps over the Allied lodgement at Naga.
Despite the free run the Allies have managed to have getting on to Luzon, I hope to be able to stall this campaign out as long as possible. There is 2000AV in Manila, and 1200 AV in the hex adjacent to it. One IJA division and two brigades are earmarked for air transportation in to Luzon, and fast transport task forces are already moving supplies in preparation of the Siege of Manila.
North Pacific
Just as March turns to April and the situation on Luzon calms down, a massive US naval presence appears in the North Pacific, heading for the Kuriles.
Unlike 1942, this time the Allied ships are spotted in plenty of time, and massive preparations are made to attempt to fend off the Allied ships.
The Allies land on April 2nd, 1945.
The Japanese naval and air response is massive. Large numbers of aircraft, staging from Hokkaido, are ready to intervene against the Allied fleet, while large numbers of IJN warships, mostly E-class coastal defence ships, are mobilised to interdict the landings. Allied carrier aircraft are kept on a tight leash, and there are no naval strikes attempting to clear the waters of these combatants. The KB was instructed to make a quick replenishment stop at Nagasaki and move with all speed to the Kuriles.
The Allies put troops ashore at Onnekotan-jima, Shimushiri-jima and Shasukotan. Both Onnekotan-jima and Shimushiri-jima have a single division in garrison and level 6 forts, while Shasukotan has a token garrison of an IJA battalion.
While the Allies are unloading troops, the IJN ships off-shore move in to make their attacks on the Allied armada. Confused by several forces of IJN warships operating close to them in the darkness, USN surface combat groups covering the invasions let a trio of IJN destroyers slip in to the CVE force covering the landings in daylight, to devastating effect:

However, the accumulated damage was too much for the damage control teams on the IJN destroyers, and all three sank before making it back to a safe port.
By the end of D-Day on April 2nd, the situation became quite clear in that Allied forces had landed in sufficent strength to take Onnekotan-jima, but were stalemated on Shasukotan and Shimushiri-jima.
IJN interference with the landings continued on the night of April 3rd, with a force of Japanese motor-torpedo boats breaking past the covering Allied warships and making a effective attack on ships unloading troops at Shimushiri-jima:

Several more engagements followed this one, with IJN MTB's engaging Allied LST's, sinking several and disrupting landing operations.
The USN gets some revenge, sinking the CL Sakawa off Hokkaido with three torpedoes. This recently completed ship saw no real combat service and was sunk on it's way north to the combat area.
Daylight on April 3rd brought more surface engagements with IJN E-class ships, which generally resulted in a net loss to the IJN. However, a force of the E-class warships were able to again engage a USN task force of LST's and further disrupt landing operations.
Japanese attempts at air attack on the USN ships were hampered by poor weather and poor co-ordination, leading to heavy losses amongst the attacking squadrons. However, a single IJA Peggy bomber was able to ram the CVE Anzio.
By April 4th, the IJN had been able to bring large numbers of warships in to the combat zone, which effectively clouded the battle area for USN carrier operations. The key engagement occurred at night between a group of IJN E-class warships and the main USN carrier group.

While the damage to the USN carriers was minimal, this triggered their retreat back eastwards. In game terms, these surface engagements sent the US CV TF back to it's home base in the Aleutians.
While the US CV's were returning east, land-based torpedo bombers took off on night attack missions on the US ships off Shimushiri-jima in what was the most effective night attack of the war to date.

With dawn on April 4th, the situation was dire for USN forces off Shimushuri-jima. Their escort carriers were bloodied and their fleet carriers steaming the wrong direction, and the front-line warships of the IJN had been committed to destroying them.
The only American surface combat group that managed to interfere with the IJN warships was a destroyer force led by the CLAA Flint, which inflicted significant damage to the slow battleship element of the IJN fleet, but suffered serious losses in turn.

While the slow battleship force was battered, the BB Hiei was able to close and engage the force of USN escort carriers covering the invasion. The lightly armed American ships were not capable of effectively resisting and the poorly armoured CVE's did not stand up well in a surface engagement,

While the USN CVE's off Shimushiri-jima were being battered, the IJN added insult to injury when a further group of E-class warships managed to sneak in to range of the CVE force covering Onnekotan-jima. While lacking the speed, armament or armour of the first-rate IJN warships, these small escort ships were able to cause problems for the lightly armoured CVE's.

With the Allied CVE force harried severely by the surface warships of the IJN, it offered the Japanese squadrons based on Hokkaido and other Kurile Islands a free hand at attacking Allied shipping. Over a series of attacks, most unopposed, what had been started by the warships of the IJN was completed.
The summary of the damage:
Escort Carriers
- CVE Windham Bay: Kamikaze hit 1, Bomb hits 5, heavy fires, heavy damage, confirmed sunk

- CVE Bismarck Sea: Kamikaze hit 1, confirmed sunk

Ashore, the Allies seem to fare somewhat better. While the attack on Shimushiri-jima is stalled, the Allies attack at Onnekotan-jima, knocking forts down to 5 on the 3rd, and down to level 4 on the 4th. The massively outnumbered defenders are doomed. Meanwhile, on Hokkaido, preparations are underway for the rapid reinforcement of Shimushiri-jima, with the goal of driving the Americans back into the ocean. The KB, refueled and ready for combat, will pursue the American warships for the decisive battle.
