Using diary entries, interviews and first-hand accounts, this vivid narrative brings to life the struggle in the air over the island of Guadalcanal between August 20 and November 15, 1942.

For 40 years from 1961, the late Eric Hammel interviewed more than 150 American participants in the air campaign at Guadalcanal, none of whom are still alive. These interviews are the most comprehensive first-person accounts of the battle assembled by any historian. More importantly, they involved the junior officers and enlisted men whose stories and memories were not part of the official history, thus providing a unique insight.

The battle of Guadalcanal was the first offensive operation undertaken by the US and its allies in the Pacific War. "Cactus," the code name for the island, became a sinkhole for Japanese air and naval power, experienced forces whose losses could never be made good. The three months of air battles between August 20, 1942, when the first Marine air unit arrived on the island, and November 15, when the last enemy attempt to retake the island was defeated, were perhaps the most important of the Pacific War. After November 15, 1942, the US never looked back as its forces moved across the Pacific to the war's inevitable conclusion.

The Cactus Air Force is a joint project between the late Eric Hammel and Pacific War expert Thomas McKelvey Cleaver, and is unlike any other of the many histories of this event that have been published over the years.

The late Eric Hammel is recognized as one of the leading American military historians, with more than 40 well-received books that are considered authoritative on their subjects published over a 50-year career.

Co-author Thomas McKelvey Cleaver is one of Osprey's most successful authors and is also a recognized authority on the Pacific War with his best-selling books Pacific Thunder and Tidal Wave and he brings a lifetime of study to the project.

“Hammel and Cleaver have once more brought Guadalcanal front and center. Theirs is a harrowing tale of unpreparedness, intelligence and leadership failures, of learning hard lessons in the furious crucible of war, of sacrifice and loss, of great courage, and, ultimately, of a great victory secured at a fearsome cost.” —Richard P. Hallion, former Historian of the US Air Force

“Overstating Eric Hammel's impact as a military historian is impossible. His focus on aviation-and Guadalcanal in particular-has seen few equals. Today, we benefit not only because Hammel had the foresight to capture the first-person accounts of thousands of veterans, but also because he possessed the knowledge to place them in the proper context.” —Jay A. Stout, author of 'Jayhawk: Love, Loss, Liberation and Terror Over the Pacific'

“Eric Hammel's research, done when no one else was interested in learning these stories, has allowed a story we all think we know well to be told anew, through the words of those whose stories were never told before. The Cactus Air Force is a vital contribution that provides new information about this crucial battle.” —Barrett Tillman, author of 'Whirlwind: The Air War Against Japan, 1942–1945'

“Eric Hammel was outstanding among us in finding participants and conducting interviews. His best work glowed that way, notably in his Guadalcanal and Iwo Jima publications.” —Richard B. Frank, author of 'Guadalcanal: The Definitive Account of the Landmark Battle'

“This superbly written description of the conflict in the Pacific chronicles these battles with reference to official records and, more importantly, personal accounts of the US participants taken from interviews and diaries. These graphic and moving accounts create a vivid narrative for the reader.” —Flypast

“"The Cactus Air Force: Air War over Guadalcanal" is an extraordinary and singularly invaluable series of American military eye-witness accounts of one of the major battles in the Pacific Theatre of World War II.” —Midwest Book Review
