The island of Bougainville in the South Pacific was the site of one of the largest and most gruelling campaigns fought by Australian forces during the Second World War. During the offensive against the Japanese from November 1944 to August 1945, more than 500 Australians were killed and two Victoria Crosses were awarded. A veteran later described Bougainville as 'one long bloody hard slog'. Despite this, little is known about the campaign, which was dismissed as an unnecessary and costly operation. In the first major study of the Bougainville campaign since publication of the official history in 1963, Karl James argues that it was in fact a justifiable use of Australia's military resources. He draws on original archival research, including wartime reports and soldiers' letters and diaries, to illustrate the experience of Australian soldiers who fought in the campaign. James shows that it fulfilled the Australian government's long-standing plans for victory in the Second World War. Generously illustrated with over forty photographs, this important book tells the story of a campaign often overlooked or ignored in Australia's military history.
