MacArthur's Greatest Triumph - The War at the End of the World
Douglas MacArthur was controversial by any measure, but the campaign that cemented his greatness was the 2 year battle to drive the Japanese from 
New Guinea and prevent the loss of Australia. James Duffy's, "The War at the End of the World: Douglas MacArthur and the Forgotten Fight for New Guinea 1942-1945" provides a superb historical backdrop and riveting detail of the savage fighting that occurred across 1500 miles of Pacific jungle.
