A number of scholars have found that wartime conditions often bring about conflict between the press and the military. This study documents the various incidents between the United States Army and various Mexican and United States newspaper editors that led to at least ten cases of newspaper suppression, the occasional use of prior censorship, and other forms of press harrassment. Overall, the United States press enjoyed a wide latitude of freedom in its coverage of the Mexican War, but this freedom was not absolute. The energy of the United States press in covering the war was to influence future war coverage, but the Army's implementation of martial law served as a counterforce to that coverage, setting a precedent for press coverage of the United States military in future wars.
