José Guadalupe Gallegos

José Guadalupe Gallegos was a prominent Hispano leader in New Mexico’s territorial history. His life included military leadership during the Civil War, territorial politics, and civic contributions, and reflects the transition of New Mexico from a Mexican territory to a U.S. territory.

Gallegos was born on April 13, 1828, in San José (San Miguel County), in the First Mexican Republic (now New Mexico). His parents were José Fernando de Jesus Gallegos and Maria Juliana Padilla. Gallegos grew up in the San Miguel del Vado Land Grant area. This region—established in 1794—was a frontier in Mexico’s holdings, serving as a buffer against raids and hosting a trade hub along the Santa Fe Trail. On November 18, 1843, at age 15, he married Josefa Gutierres. Together, they had six children.

In 1848, the Treaty of Guadalupe Hidalgo ended the Mexican-American War, and in that treaty, Mexico ceded New Mexico to the United States. In 1850—as the U.S. Congress grappled with slavery and tried to balance future legislative power—New Mexico’s territorial status and path to statehood became official as part of the Compromise of 1850. The territory transitioned from a provisional military government to a territorial government. Initially governed under the Kearny Code, the territory’s administration shifted to an appointed governor, an elected legislature, and a judicial system. Santa Fe became the capital in 1851. The territorial government faced challenges from tensions over slavery, Native American resistance, and cultural conflicts among Hispanics and Anglos.

Under these circumstances, Gallegos entered the territory’s politics. At age 23, he was elected Sheriff of San Miguel County, serving from September 1851 to September 1853. Though initially unsuccessful in an 1853 election for the territorial legislature, he later won and served in four of the six assemblies between 1855 and 1861, representing San Miguel County. He also served as House Speaker in the 8^th Assembly (1858-1859) and Council President in the 9^th and 10^th Assemblies (1859-1861).

Beyond his political roles, Gallegos participated in the territory's economic and cultural development. He was a founding member of the Historical Society of New Mexico, playing a key role in its legal incorporation in 1859. He also helped establish the New Mexican Railway Company (1860), the Montezuma Copper Mining Company (1861), and the New Mexico Wool Manufacturing Company (1861).

Gallegos also participated in the territorial military, gaining valuable experience for expeditions in the southwest. In 1854, he served as a brigadier general in the volunteer Mounted Militia of New Mexico. It was formed to protect communities from Native American attacks. He later commanded the Second Brigade and Second Division of the militia and participated in an engagement with Jicarilla and Mescalero Apaches at the junction of the Mora and Sapello Rivers.

When the Civil War erupted, Gallegos answered the Union’s call. On August 26, 1861, he was commissioned as a Field and Staff Colonel, commanding the 3rd New Mexico Volunteer Infantry Regiment, a unit of 1,000 men raised to defend the territory from Confederate attacks.

Starting on November 22, 1861, Colonel Gallegos served as the Post Commander at Hatch's Ranch, a strategic outpost that monitored enemy movements. Confederate supporters envisioned capturing territory in the southwest or controlling important trails. Gallegos coordinated logistical work, including the construction of a road between Las Vegas, New Mexico, and Fort Union. The 3rd New Mexico Volunteer Infantry participated in the New Mexico Campaign, and some companies served as a reserve force at the Battle of Valverde. Colonel Gallegos's six-month enlistment concluded on March 6, 1862, before the Battle of Glorieta Pass. 

Following his brief Civil War service, José Guadalupe Gallegos returned to civilian life. On May 18, 1867, at the age of 39, he suffered a carriage accident and drowned. Gallegos is buried in Anton Chico, New Mexico.

Despite his early death, Gallegos helped to shape New Mexico’s history and the Civil War in the southwest territories. His leadership in the territorial legislature, dedication to fighting for the Union, and efforts to establish cultural and economic institutions were an important part of preserving the Union in the West.
