Lt. William Diebold served in the Army's Air Transport Command in the China-Burma-India theater of World War II and never fired a weapon in battle. Like many men who flew the Hump, he never saw on-the-ground combat, but he fought bravely by saving lives. Flyers who crossed the eastern Himalayas to keep the allied armies in China supplied with food, fuel, and weapons against Japan—preventing it from concentrating its power in the Pacific—often flew in zero-visibility, sometimes crashing into mountains or falling from the sky from Japanese Zero attacks. Those pilots who survived, Bill Diebold rescued.

In Hell Is So Green, Diebold vividly describes the heat and stink of the jungle; the vermin, lice, and leeches; the towering mountains and roaring rivers. Rich with war slang, wisecracks, and old-fashioned phrases, his story reverberates with authenticity and represents the stories of many men that have never been told. After the author's early death, the manuscript was put away in an attic—until now. Here, from the shadows of that attic, comes a compelling story of courage under fire and heroism for the ages.
