Jesse L. Reno - Mexican-American War

Mexican-American War

During the Mexican-American War in 1847, Reno commanded an artillery battery under General Winfield Scott and fought in the Siege of Vera Cruz and other battles in Mexico. Reno was brevetted twice during the war—once for "gallant and meritorious conduct" at the Battle of Cerro Gordo, and later for bravery at the Battle for Mexico City and the Battle of Chapultepec, where he was seriously wounded while commanding a howitzer battery.

After the Mexican-American War ended, Reno served in several locations, including as a mathematics instructor at West Point, as the secretary of a group assigned to "create a system of instruction for heavy artillery, and at the Ordnance Board in Washington, D.C. He was promoted to first lieutenant, in 1853, and sent to conduct a road survey from the Big Sioux River to Mendota, Minnesota. When he returned to Washington, he married Mary Blanes Cross, and the couple had five children, two of whom had notable achievements of their own: Conrad Reno became an attorney and writer of note in Boston, Massachusetts, and Jesse W. Reno graduated from Lehigh University and invented the first working escalator.

Reno's next assignment was as ordnance officer at the Frankford Arsenal, northeast of Philadelphia, where he spent the next few years. In 1857, Reno was assigned to go with Brig. Gen. Albert Sydney Johnston as chief of ordnance on a two-year expedition to the Utah Territory.
