The Japanese conquest of the Pacific comprised of a complex series of widely scattered operations intended to neutralize American, Commonwealth, and Dutch forces, seize regions rich in economic resources, and secure an outer defense line for the "Greater Southeast Asia Co-prosperity Sphere." Albeit victorious, the forces deployed from Japan and China were not always ideally trained and equipped for the challenging conditions they encountered. This book, the first of several covering the Imperial Japanese Army in World War II, examines the forces in existence at the beginning of the war, and task organization for the conquest of the Philippines, New Guinea, the South Seas area, and the Dutch East Indies, from December 1941 to the Battle of Midway in June 1942.







The bitter fighting in the Pacific Theater required new forms of warfare, and the gathering of detailed intelligence information on the remote and varied islands and their determined defenders. As a result, new scout, raider and reconnaissance units were formed

The year 1945 saw the execution of three of the Marine Corps' largest and most vicious battles - Peleliu, Okinawa and Iwo Jima - and the Marines' performance in these arenas reflected the massive changes that had taken place in the Corps over the preceeding four years. These battles, the recent re-organisations, new units and weapons systems were intended to prepare the Marines for the planned invasion of Japan in November 1945. In this companion volume to Order of Battle volumes 1 and 7, Gordon Rottman studies this re-organisation in detail, discussing new assault units, provisional combat support groups, and service units.
