In February 1943, Japanese troops finally withdrew from Guadalcanal, part of an island group commanding the approaches to northern Australia. The evacuation marked the end of a relentless six-month contest for control of this remote, jungle-clad territory. It was the end point for an extraordinary series of conquests over the previous 15 months, in which Japanese forces had occupied vast tracts of South Asia.
Japan’s empire stretched from eastern China down to Papua New Guinea, with the colonial possessions of Britain, France, the Netherlands and the USA falling in a series of rapid moves. Since its first expansionist surge in 1931, imperial Japan had acquired more than 30 million square miles of land. This remarkable run of success would come to an end after the Battle of Guadalcanal.
During the desperate struggle over the island, US forces not only had to contend with one of the most inhospitable environments on earth. They also had to overcome ingrained divisions between their army, navy, and air force, while tackling formidable logistical challenges. They faced a determined and battle-hardened adversary who had the upper hand for much of the conflict. Why did this island become the focus of such intense combat, and how are we to explain the outcome?
