The 1941 Japanese Pacific onslaught saw the defeat of Allied forces on all fronts, with the Philippines, Netherlands East Indies, and Commonwealth possessions falling under their control.During 1942-43, the Japanese consolidated their gains and redeployed forces in an attempt to break the Southern Lifeline between America and Australia. These plans were affected by the defeat at Midway, which forced the Japanese onto the defensive. This book examines Japanese forces employed in the follow-on conquests of 1942-43, and describes how unit organization, weaponry, and equipment were found lacking in the harsh environment of the Solomon Islands and on New Guinea.
