Volume Four chronicles aerial warfare in the South Pacific in the critical period between 19 June and 8 September 1942. It can be read alone or as a continuation of the first three volumes that spanned the first six months of the Pacific War, culminating in the Battle of the Coral Sea. No aircraft carriers appeared in New Guinea waters and the air war was fought solely by land-based air units. This was in the face of an increasingly complex strategic situation that saw the Japanese land at both Buna and Milne Bay. For the first time, airpower in the theatre was tasked to support the land forces of both sides which became engaged in a bloody struggle in the mountains of Papua and then the narrow muddy quagmire of Milne Bay. Never before has this campaign been chronicled in such detail, with Allied accounts matched against Japanese records for a truly factual account of the conflict. Illustrated throughout with photographs, illustrations and profiles.
