Air Operations in the Lebanon Crisis of 1958 is one in a series of studies on air operations in international incidents prepared by the USAF Historical Division Liaison Office at the request of the Directorate of Plans, Headquarters USAF. Written in 1959, this study is based chiefly on the raw materials of historical writing--messages and correspondence--and command and unit reports on the operations available at that time. State Department, JCS, Air Force, Army, Navy, and Marine Corps materials were used in its preparation. Originally prepared in a very few copies, the study has nevertheless been extensively used within the Air Staff, the JCS, and in the Department of Defense. In response to many requests for wider dissemination of the study, DCS/Plans and Programs, Headquarters USAF, has concurred in its reproduction for a larger distribution. Written by Dr. Robert D. Little and Mrs. Wilhelmine Burch, this study is of special significance in connection with planning and preparations for local wars and incidents. In this operation the American forces experienced no combat action, but the possibility of action was constant and the deployment of forces to the objective area was of first importance. To achieve a meaningful historical context for the military operations, the political and diplomatic background has been presented in some detail.
