In early 1941 the Intelligence Training Centre of the British War Office inaugurated politico-military courses at St. John's College, Cambridge. Their purpose was "to train officers in postwar reconstruction and other missions incident to military operations in foreign countries." Two US Army officers, Maj. Henry H. Cumming and Lt. Charles A. H. Thomson, attended the third course, which began in October 1941, and thereby became the first American officers to receive military government training. The politico-military courses dealt with history, geography, economics, and politics and aimed at giving the officer-students background knowledge rather than specific instruction in military government.
