By 1945, General MacArthur's forces had advanced from Papua to the Philippines and to Borneo. The vast majority of the troops, supplies, and equipment for this campaign were transported by sea, and MacArthur's success was based on 22 amphibious assaults. Soldiers and Marines did the ground fighting and MacArthur's air forces eventually ruled the skies, but it was the ships of the United States and Australian navies that delivered them to the battlefronts and supported them. This book reveals facts of the Royal Australian Navy's crucial role in World War II.
