The Mariannas after the attack, where Japanese Task Force 1 is based. Ground based aircraft were not used in the attack because they were just out of range | The US base in the Gilbert Islands, with ground based bomber squadron having suffered heavy losses. The Islands are also a strategic objective of Japanese Forces |
Turn 2 - February 1944 - US Initiative |
-
US Task Force 1 returns to the Marshall Islands to attack the third island, Eniwetok,
without Marines this time. |
New
Orleans support forces leaves Fiji to join US Task Force 1 in attack on Eniwetok in the Marshalls | Japanese
land-based bombers attacks New Orleans but is counter-attacked by US fighters |
- Fiji task force moves to join Eniwetok invasion force (Task Force 1) . US Task
Force 1 is attacked by Japanese carrier-borne aircraft, US fighters meet challenge,
one US fighter group is lost from carrier USS Cabot, other aborted, 1 Naval Air
depleted from CV Bunker Hill. |
The
Fiji Task Force with New Orleans arrives at Eniwetok and is immediately attack by Japanese Naval Air | Close-up
of the attack on Eniwetok, note that Naval Air is committed from both Task Forces |
A
US land-based fighter-bomber squadron joins the land assault but is attacked by Japanese land-based fighters | Situation check: US Task Forces prepare for the invasion of Eniwetok after air war is resolved |

Battle for Eniwetok & Wotje |
Eniwitok
and Wotje are successfully attacked and occupied by US Forces | The
Marshalls are now occupied by US Forces and Task Force groups begin to disengage from the battle |
Task Forces disperse and US Forces consolidate the islands, with engineers fortifying Eniwetok | The Japanese base at Truk, where Japanese Task Force 1 resides still threatens the Marshalls to the east |
This image demonstrates the proximity of the two opposing forces, see also Japanese fighter based on Wake to the north | The
carrier USS Cabot and the heavily damaged battleship Indiana retreat to Midway for repairs, New Orleans escorted |
Turn 2 - February 1944 - Japanese Forces Regroup |
-
Japanese Task Forces 2 & 3 relocate to Truk in the Carolines and Wake respectively,
carrying with them reinforcement troops (6-3 infantry divisions) x 2. |

battle nearly over, the Japanese commander, under enormous pressure decides to disengage from the battle |
- The Japanese Task Force
returns to the Carolines - US Task Force 1 returns to the Marshalls, with the carriers USS Langley departing for Pearl Harbour for restoration of her aircraft lost during the battle. USS Bunker Hill joins her to have her naval-air repaired and upgraded following an early engagement in the battle. |
Turn 3 - March 1944 - Situation Report |
The
battle for Palmyra demonstrated the strength of bomber and fighter-bomber squadrons,
which were not engaged by Japanese fighers from their carriers as all were intercepted
by US naval-air from their carriers. This in turn allowed the bombers overwhelming
attack strength against the Japanese carriers. A +2 die-roll modifier helped a
great deal (as the US bombers were all land-based bombers), and were allowed multiple
strikes according to their combat strength - 15 strikes in all! With hindsight the Japanese Task Force could have avoided most US land-based bombers and sailed north of the Marshall Islands instead. Unfortunately a bad decision was realised too late and the task force was unable to turn-around once it was intercepted. The situation does not, however, reflect the historical events, and there was no such early victory over the Japanese Imperial Navy. Instead such a victory was to prove elusive until the battles of the Phillipine Sea and Leyte Gulf, later in 1944. |
Seasonal Turn - Spring 1944 - Reinforcements Arrive |
US
Reinforcements Battleships Iowa and New Jersey join Task Force 2, along with 3 CV's, Franklin; Wasp II and Hornet; CVL Bataan also joins, with depleted air. Japanese Reinforcements CV Taitio joins Task Force 1 with naval-air plus one 4*-4/4 fighter based at Kavieng (Bismarck Archipelego) |
