Following his role as a federal officer, Fierro went on to work as a railway man, eventually being absorbed into Villa's ranks.

As a child Fierro played Benito Juárez and shooting Emperor Maximilian in the Cerro de las Campanas.

He had come to this corp thanks to the recommendation of Don José María Paredes and where he always stood out for his bravery and intelligence in the assigned conditions.

Due to a visit by Vice President Ramón Corral, a dance was organized at the Government Palace.

Don José María Paredes pleaded with Luis Medina Barrón for Fierro to be promoted to lieutenant and thus with a higher military rank he could woo the wealthy Luz.

A curious fact was that on June 4, 1912, when Villa was taken prisoner to Mexico City, it was Fierro himself who would drive said train.

Before the battle began Fierro had been sent South to destroy the railroad tracks, forcing the federal soldiers to halt.

[5][6] A 1930 novel El águila y la serpiente by Martín Luis Guzmán gives Fierro his nom de guerre.

One captive is noted as making it over the wall and to freedom, only after Fierro stopped to massage an achy trigger finger.

[2][3][6][8][9] Another account recounts that Fierro would ask each prisoner if they would rather return to their family, or join the army of Pancho Villa.

It is often stated the case was a sham, simply to continue to retain support from the much needed railway workers.

A conflicting story exists in which Benton drew his pistol but was detained and removed from the town at night.

The decision was made following the election of Roque González Garza by the Mexico City Convention.

Fierro was again defeated, losing two thousand men and eight hundred horses, the loss forced him to abandon Guadalajara as well.

The weight of his belt, loaded with gold coins and material is said to have prevented him from being able to escape, although it is difficult to conceive great wealth in an army in frank defeat.

His body was retrieved by Kingo Nonaka, a Japanese photographer and combat medic for the Mexican Revolution.

Fierro was portrayed by Damián Alcázar in the 2003 HBO made-for-television film And Starring Pancho Villa as Himself.
