Overview
-

In early 1943 Japanese forces in the South Pacific had suffered three key strategic setbacks at Guadalcanal, Kokoda and the Battle of the Bismarck Sea. However Japanese strength in the theater was far from spent, and the commander of the IJN Combined Fleet Admiral Yamamoto sensed an opportunity.

By temporarily bolstering his air force at Rabaul with carrier-based airpower, Yamamoto assembled a strike force of hundreds of aircraft. With these he planned to overwhelm Allied defenses in a multi-day blitz against four crucial locations. Named Operation I-Go, it would be the largest IJN air operation ever launched in the region.

The odds favored the plan, but by 1943 I-Go was a huge gamble. Would it strike a body blow and give the Allies reason to pause their advance? Or would it cause irrecoverable wastage of IJN offensive air power?

The results of I-Go were surprising, although it only achieved a fraction of what the Japanese claimed. The greatest irony was that it led to the death of its architect, Yamamoto.

This is the first detailed account of I-Go written with reference to both Japanese and Allied sources, and it surely sets a new historical benchmark for this key chapter of the Pacific War.

REVIEWS
-

"By comparing records from both sides, the chapters assemble a much more comprehensive—and accurate—picture of events. "

- Stone & Stone Second World War Books

"For the dedicated WWII aviation historian it contains every detail about the 4 main air strikes that constituted OPERATION I-GO. But it also succeeds at the level of the casual reader whose interest might be the duels between the opposing air forces or knowing about the camouflage and markings of the aircraft involved."

- j-aircraft.org

"...will be of great interest to aircraft modelers and aviation historians alike."

- AMPS Indianapolis

""For the gamer, it's a nice encapsulation that would make for an interesting campaign game, and both modelers and miniature gamers alike would enjoy the color camouflage schemes."

- Historical Miniatures Gaming Society

"[Michael Claringbould] offers readers yet another fine Pacific War-themed book which includes a crisp, yet brief analysis of Admiral Yamamoto’s last operation. His sagacious inclusion of Japanese sources provides much more context than previous histories which featured the Allied version of events and did not delve into detail regarding factors which influenced the Japanese failures, such as disease, training difficulties and crushing attrition."

- Naval Historical Foundation

"It explores elements of the operation in detail, with reference to individual’s accounts and experiences, plus support from period photos plus a selection of detailed maps, diagrams and tables containing orders of battle. Of interest to modellers, 58 colour profiles depict a variety of Allied and Japanese aircraft type involved in the operation."
