World War II U.S. Army corps commanders were the orchestrators of combat, the men responsible for coordinating the fighting power and tactical deployment of divisions. Twenty-two U.S. Army corps were actively engaged in combat operations during World War II. They were led by a total of thirty-four general officers. Dr. Robert H. Berlin identifies these leaders, assesses their military careers, and discusses why they were selected for corps command. This Combat Studies Institute Special Study traces the interwar asignments of these future generals, all of who served at least one tour as instructors in the army education system. The study also explores which corps commanders were promoted and which were relieved. Dr. Berlin's well-documented study reveals how World War II corps commanders were prepared for senior-level command. -- Abstract.
