New Guinea War

One American soldier called it "a green hell on Earth". Monsoon-soaked wilderness, debilitating heat, impassable mountains, torrential rivers, and disease-infested swamps - 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.

While the Marine Corps island-hopped across the Pacific from Guadalcanal to Saipan to Iwo Jima, the U.S. Army was locked in a grueling, multiyear fight for the jungle island of New Guinea, which in Japanese hands threatened both Australia and the vital supply lines stretching to the United States. Forces under Douglas MacArthur intended to deny the Japanese this opportunity and use New Guinea as a stepping stone on the road back to the Philippines and, beyond it, Japan.
