Every March 16th marks the anniversary of the founding of the Mounted Grenadiers Regiment, a unit established in 1812 by then-Lieutenant Colonel José de San Martín. From its inception, the regiment distinguished itself through its discipline, bravery, and deep sense of duty—values that made it one of the most iconic symbols of honor and patriotism in Argentine history.

Convinced that independence required not only military skill but also a firm moral commitment to the homeland, San Martín trained his men under strict principles of honor, loyalty, and sacrifice. In this way, he not only prepared them for combat but also established a tradition that endures to this day.

The regiment’s baptism of fire took place at the Battle of San Lorenzo on February 3rd, 1813. From that point on, the grenadiers played a leading role in some of the most decisive campaigns of the South American emancipation movement, including the Crossing of the Andes in 1817 and the momentous Battle of Ayacucho in 1824. In just a decade of military campaigns, the unit earned 22 decorations, leaving a legacy of heroism and commitment to the freedom of the peoples.

In the early 20th century, the regiment assumed a new institutional responsibility: it was assigned the mission of serving as the Presidential Guard, a role it continues to fulfill today. In this capacity, its members participate in official events, ceremonies, and security duties related to the institutions of the Republic.

Currently, the regiment consists of four mounted squadrons (Riobamba, Junín, San Lorenzo, and Maipú) that participate in military parades and ceremonies, and foot squadrons, such as Chacabuco and Ayacucho, responsible for providing security for the head of the National Executive Branch at the Casa Rosada and the Presidential Residence in Olivos. Among its duties is also the guarding of the Liberator’s remains at the Metropolitan Cathedral of Buenos Aires.

The regiment is further accompanied by the Alto Perú Military Fanfare, renowned for its gray horses, brass instruments, and distinctive timpani, which lend a unique character to every official ceremony.

Likewise, the unit maintains permanent detachments in Yapeyú, San Martín’s birthplace, and in San Lorenzo, the site of his first battle. These presences reinforce the historical link between the regiment and the major milestones of the struggle for independence. In addition, the Regiment is tasked with guarding the Liberator’s home in Boulogne-sur-Mer, France, where he spent the final years of his life.

Today, visitors can witness the daily changing of the guard performed by the House of the Rose Grenadiers, as well as the raising and lowering of the flag in Plaza de Mayo.

214 years after its creation, the Mounted Grenadiers Regiment continues to embody the values that gave rise to it: courage, honor, discipline, and a dedication to service. On this date, we renew our recognition of those who served and continue to serve in this historic unit, whose legacy remains deeply tied to the defense of freedom and the nation’s memory.
