Equalling Tarawa, Iwo Jima and Okinawa in scale and ferocity, the battle for Peleliu has long been regarded as the Pacific war's 'forgotten battle'. Originally planned to secure General MacArthur's eastern flank during his invasion of the Philippine Islands, the assault became superfluous after a massive carrier-based attack on the Palau Islands some weeks earlier destroyed all aircraft and shipping in the area, virtually isolating the Japanese garrison, forcing them into a battle of attrition from carefully prepared positions in the Umurbrogol Hills. This book details the operation that became a close-quarters slog of unprecedented savagery, one that with hindsight should never have been fought at all.
