After his excellent book "Darwin Spitfires", Anthony Cooper's new book "Kokoda Air Strikes: Allied Air Forces in New Guinea, 1942" is now available, though it appears it is only available in Australia:
The author of the bestselling Darwin Spitfires casts a forensic eye over the role that Allied air forces played – or failed to play – in crucial World War II campaigns in New Guinea.
"This is the story of the early battles of the South West Pacific theatre – the Coral Sea, Kokoda, Milne Bay, Guadalcanal – presented as a single air campaign that began with the Japanese conquest of Rabaul in January 1942.
It is a story of both Australian and American airmen who flew and fought in the face of adversity – with incomplete training, inadequate aircraft, and from poorly set up and exposed airfields. And they persisted despite extreme exhaustion, sickness, poor morale and the near certainty of being murdered by their Japanese captors if they went down in enemy territory."
