Cadets training for the Mexican Navy originally formed part of the student body, but in 1897, the Military Naval School was established as a separate institution in Veracruz.

By the next year, through the orders of War Minister General Jose Joaquin de Herrera, the Military College of Mexico was relaunched as a separate academy with headquarters at San Carlos Fortress, in Perote, Veracruz state.

As a result of this great deed, the college in March 1828 returned to Mexico City, first in the Bethelemitas convent and later in the Inquisition Palace Complex on July 1.

On September 11, a rebellion led by Generals Antonio Lopez de Santa Anna and Jose Maria Lobato denounced the election results ten days before, in which Manuel Gomez Pedraza emerged as the winner.

Two months later, on November 30, they together with Lorenzo de Zavala and Col. Santiago Garcia staged a coup d'état that took over the La Acordada building demanding that the election results be voided by Congress.

On July 13 of that year Gen. Jose Urrea bolted out of jail and led a rebellion against President Anastacio Bustamante, who was later imprisoned in the presidential residence.

The following year (1847), during the first term of Col. José Mariano Monterde Segura as commandant, the Mexican–American War reached Mexico City and the Military Academy.

Its Mexican Army defenders, under the leadership of Nicolás Bravo, former President of the Republic and a veteran of the war of independence, included about 200 members of the Corps of Cadets, aged between 13 and 19.

At the end of the battle five cadets – Juan Escutia (who reportedly leapt to his death wrapped in the Flag of Mexico), Agustin Melgar, Francisco Marquez, Fernando Montes de Oca, and Vicente Suárez – and faculty member Lieutenant Juan de la Barrera all refused to retreat and died in a final stand as the "young heroes" of Academy legend.

Each year on the anniversary of the battle, the sacrifice of the five Niños Héroes of the Military Academy is remembered nationwide, with a national ceremony at the monument with the Corps in attendance.

However a detachment of cadets from the Heroic Military College, acting on the orders of Deputy Commandant Lieutenant Colonel Víctor Hernández Covarrubias escorted President Madero from Chapultepec Castle to the National Palace on the following day.

Termed the Loyalty March, this action is still marked by an annual parade by the Corps of Cadets, attended by the present-day President of Mexico and his Cabinet.

This occurred on May 8, when on the orders of Colonel Rodolfo Casillas the cadets acted in support of regular army dragoons led by General Pilar Sanchez under attack by rebel forces in Apizaco, Tlaxcala.

In 1949, the Congress of the Union formally conferred the "Heroic" designation to both the Corps and to the Midshipmen's Battalion of the Naval Military Academy, the latter for its role in resisting the United States occupation of Veracruz in 1914.

[2] Chorus Vibre el clarín de la guerra, resuenen las fanfarrias Redoblen los tambores, una marcha triunfal Y lleven de la Patria a todos los confines Tu nombre sacrosanto, Colegio Militar Tu nombre sacrosanto, Colegio Militar

Repeat chorus The Regimental march was composed by Lieutenant José Sotero Ortiz Sánchez, in time for the college's 1947 centenary of the Battle of Chapultepec.
