Defending the Driniumor: continued
The U.S. Army's extensive amphibious campaigns in the Southwest Pacific Theater during World War II have been all but forgotten today. The conduct of those far-flung operations, the sustenance of more than twenty-seven U.S. Army infantry divisions, and the imaginative planning required for bold thrusts deep into the enemy's rear areas offer timeless lessons for commanders. Moreover, a new aspect of the Pacific War has recently surfaced: the ability of the U.S. Army to read the most secret Imperial Japanese Army (IJA) codes-in short, to "see deep" for the purposes of operational planning. This Leavenworth Paper correlates, insofar as possible, the influence of Ultra intelligence on the conduct of General Douglas MacArthur's Aitape, New Guinea, campaign. The signals intelligence community regarded the U.S. XI Corps's destruction of the Imperial Japanese 18th Army as one of the singular achievements of the intelligence craft during World War II.
