This collection includes photographs of the Mexican Expedition taken by Indiana National Guardsmen Lieutenant Joseph E. McCurdy, Sargeant C. F. Norris, and Captain Emile F. Martin. In 1916 trouble escalated on the American/Mexican border when rival political factions struggled for control of Mexico. National Guard units including Indiana, were called to active duty and assembled at Fort Harrison for induction into federal service. The units began departing in July 1916 and trained extensively during their time in Texas, culminating with 12 days of field maneuvers in November 1916 between Camp Llano Grande and Port Isabel. On November 24 the dispute was settled and the Hoosiers began returning to Fort Harrison in December 1916.
