In 1857, Tucson was established as a stage station on the San Antonio–San Diego Mail Line. In 1858, it became third division headquarters of the Butterfield Overland Mail and operated until the line was shut down in March 1861. The Overland Mail Corporation attempted to continue running, but following the Bascom Affair, devastating Apache attacks on the stations and coaches ended operations in August 1861.[citation needed]
