 While filming _Life of Villa (1912)_ (qv) a battle between the  forces of Pancho Villa and federal troops near Ojinaga, cameraman  Charles Rosher was captured by federal soldiers and brought before  their commanding general. Rosher thought he was about to be executed  as a spy, and things didnt look too good for him until the Mexican  general noticed Roshers Masonic pin in his lapel. The general then  gave Rosher the Masonic greeting; it turned out he was a Mason, too.  Instead of being shot as a spy, Rosher was treated as a guest, and  was later released after the Mexican government made a deal with the  American government that allowed their troops to cross into American  territory in order to outflank Villas forces and attack them from  the rear.
