José Mariano Jiménez
Mariano Jiménez was born in San Luis Potosí. He studied in the Colegio de Minería in Mexico City to become a mining engineer. He graduated in 1804. He soon moved to Guanajuato, where he was able to follow the progress of the conspiracy led by Miguel Hidalgo that aimed to achieve the independence of Mexico from Spain. A few days after the war started, Jiménez joined Hidalgo's army and was able to rise quickly in rank until he achieved the rank of lieutenant colonel.
He distinguished himself on the battlefield, such as during the Battle of Monte de las Cruces where his positioning of the artillery line was instrumental for the rebel victory. He was a very active officer and participated in the defense of Guadalajara and San Luis Potosí.
Mariano Jiménez went to Mexico city to ask for the surrender of the city but the viceroy denied it, he went back to Guanajuato city and participated in her defense because the city was attacked by Calleja in November 24, after he went to Guadalajara and San Luis Potosí.
A betrayal by one of his subordinates led to his capture at the Wells of Baján (Norias de Baján) in Chihuahua in 1811. He was tried for insubordination and executed by firing squad on June 26, 1811, together with other members of the insurgency such as Ignacio Allende and Juan Aldama in Chihuahua.
Jiménez's body was decapitated and his head taken to the Alhóndiga de Granaditas, where it was shown to the public inside a cage hung from one corner of the building. In 1925, his remains were moved to the mausoleum in the Independence Column in Mexico City.
