New Guinea was a battleground far more deadly than the most fanatical of enemy troops. Japanese forces numbering some 600,000 men began landing in January 1942, determined to seize the island as a cornerstone of the Empire’s strategy to knock Australia out of the war. Allied Commander-in-Chief General Douglas MacArthur committed 340,000 Americans, as well as tens of thousands of Australian, Dutch and New Guinea troops, to retake New Guinea at all costs. What followed was a four-year campaign that involved some of the most horrific warfare in history.
