FIGHTING IN A KOREAN WAR: THE AMERICAN ADVISORY MISSIONS FROM 1946-1953 DISSERTATION Presented in Partial Fulfillment of the Requirements for The Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Bryan Robert Gibby, B.S., M.A. ***** The Ohio State University 2004 Dissertation Committee: Approved by Dr. Allan R. Millett, Advisor Dr. John F. Guilmartin Dr. Alan D. Beyerchen ___________________________ Advisor Department of History Copyright by Bryan Robert Gibby 2004 ABSTRACT In the earliest days of the Korean War, the Commander in Chief of the United States Far East Command, General of the Army Douglas MacArthur reported to President Harry Truman that South Korean troops were outmaneuvered, outgunned, and appeared beaten: “South Korean casualties as an index to fighting have not shown adequate resistance capabilities or the will to fight and our estimate is that a complete collapse is possible.” MacArthur’s low opinion of Korean soldiers rested unchallenged, and remains unchallenged to this day. American advisors in Korea were responsible for the organization, training, and development of the Korean army. Fundamental to the evaluation of the Korean army’s capability is an analysis of the American military advisory missions active in Korea from January 1946 to July 1953. This dissertation examines how these missions performed their mandated duties to organize, train, and mentor the Korean Constabulary and the Republic of Korea (ROK) Army. These advisors faced tremendous challenges ranging from cultural disconnects, inexperience, scarce resources, and lack of time. The North Korean invasion in June 1950 revealed crucial weaknesses in training, experience, leadership, and firepower. These weaknesses nearly brought the ROK Army to its knees by the spring of 1951. Once truce negotiations began, however, new command emphasis, new leadership, greater resources, and a coherent vision for reform produced a movement to create a new army that was better led, reorganized, and expanded. In the process, the Koreans developed confident leadership, trained units, and tactical and technical skills in fighting modern war. This new ROK Army fought critical battles from October 1952 through June 1953 that set the conditions for an Armistice agreement in July 1953. ii This study concludes that the successful reformation of the Korean Army (1951- 1953) under the supervision of its American advisors enlarged the fighting ability of the Eighth United States Army as a whole. By the end of the war, Koreans were bearing a military burden that was inconceivable just two years earlier. It is improbable that an armistice agreement could have been signed without a demonstration of their increased fighting ability. iii For my parents, Dr. L. Bruce and Haydee Gibby and For Desrae iv ACKNOWLEDGMENTS I served in Korea as an Army officer for two and a half years, from 1997-2000. Koreans are industrious, cultivated, kind, and respectful. The older generation especially was solicitous. Never did I feel out of place. For this, and many other, reasons, I wish to thank the people of the Republic of Korea for their hospitality and friendliness towards American servicemen and women. My study of US-ROK governmental and military relationships during the Korean War has only increased my admiration for the “Land of the morning calm.” The completion of this project could not have been realized without the generous assistance I received from several research institutions. The personnel of the National Archives and Records Administration at College Park, Maryland, Beth Lipford, Will Mahoney, and Rich Boylan, provided assistance in finding the documents related to the United States Military Advisory Group to the Republic of Korea and the United States Army Forces in Korea. Many of these records are not yet fully catalogued or organized, so their patience and expertise was invaluable. A special thanks goes to Susan K. Lemke, the National Defense University Special Collections, Fort Lesley J. McNair, Washington, D.C. Her guidance through various security protocols allowed me to be one of the first scholars to have unfettered access to the papers of General Maxwell D. Taylor. Ms. Lemke generously allowed me to make copies of any unclassified documents that I wanted – a grand gift indeed to any researcher. Cynthia Brougher and Joanne Hartog of the George C. Marshall Library and Archives provided valuable assistance with the voluminous collections of George C. Marshall, James A. Van Fleet, and Walton H. Walker. v Dr. Geoffrey Parker, Dr. John Guilmartin, and Dr. Alan Beyerchen of the Ohio State University have all contributed to this study in material and psychological ways. Thanks to their mentorship, I learned that fighting is never the full story – training, organization, logistics, and culture also play a part, sometimes in obvious ways, sometimes more subtly. As a rotating faculty member in the Department of History, United States Military Academy, I must acknowledge the tremendous support and encouragement I have received from Colonel Robert A. Doughty (Department Head), Colonel Lance A. Betros (Deputy Head), and Lieutenant Colonel Matthew Moten (Chief, Military History Division). I especially owe a debt to my division chief, who not only read and gave constructive criticism on four chapters, but also provided me with time to complete this project. The Office of the Dean also provided generous financial support for research trips to Washington, D.C., Carlisle Barracks, Pennsylvania, and Lexington, Virginia. This history of the American advisory missions would be nothing without the men who were there. Harold S. Fischgrund read and commented on a draft of the first two chapters. F. Foster Cowey, Minor A. Kelso, Ralph Bliss, Robert G. Shackleton, Edwin J. Stewart, and Leon Sembach were all generous with their time, precious memories, and patience. As an historian, I am indebted to their first-hand observations. As a fellow officer and veteran of Korean service, I regard their commitment to two armies as a model for duty and honor. I am most appreciative to my dissertation advisor, Dr. Allan R. Millet of The Ohio State University. I owe him a great intellectual debt. A generation of officer- historians has matured under his guiding influence, and I consider it a privilege to count myself as part of that generation. Dr. Millett provided me not only encouragement but access to his personal collection of correspondence, recordings, and official documents. Lastly, I thank my wife Desrae and our four children: Paul, Peter, Parker, and Preston. Desrae, a soldier’s wife, has patiently and without complaint (nearly so) gone far above the demands of duty, living – one page at a time – some of the most forgotten aspects of the Korean War. vi VITA April 7, 1969………………………..
