History of Fort Union National Monument
Fort Union National Monument is located in northern New Mexico in Mora County. The site preserves one of three forts that were built on the land through history. There are also impressive ruins of the third Fort Union.
Fort Union was the largest U.S. military frontier posts in the region during its time. All three forts built were located along the Santa Fe Trail which was a vital route in terms of trade, mail, military supplies, and wagon travelers.
The Santa Fe Trail ran from Missouri to Santa Fe, New Mexico and served many purposes. The route was established by a Missouri trader in the early 1820s and was an important trade route. During the Gold Rushes of California and Colorado, the trail was widely used.
It was also used as a stagecoach route for settlers headed west and part of the famous Pony Express, the mail system that was used briefly in the 1860s, before the telegraph and railroad made communication much most accessible.
The decision to build a military fort in this area stemmed from many needs. The fort served as protection for the Santa Fe Trail, it was the Army supply spot for the Southwest, served as a stopping point for wagon stages, and provided a meeting point to discuss movements involving the native tribes in the area.
The first fort was completed in 1851. It was an unimpressive project of log cabins along the Coyote River. This site did not last long. In 1861, a new fort was built as the nation was beginning its Civil War.
The fort, built in the strategic star-shaped form, included ditches, parapets and a large arsenal. In 1863, the addition to the fort was built at the location of the first. This included multiple adobe structures and the site was completed in 1869.
The location of the fort did not lend to convenience in food and provisions for those at the fort. Most supplies had to be transported by way of the Santa Fe Trail from Fort Leavenworth in Kansas.
As the nation began settling the west in droves, Fort Union became as highly settled and traveled through as the town of Santa Fe itself.
After the completion of the Transcontinental Railroad, and subsequent railways eventually led to the Santa Fe Railway crossing through the Mora Valley and ended military movement across the trail.
After the United States acquired the Southwest in the Mexican-American War in the 1840s, the nation also acquired the long standing conflicts with the natives who had lived on the land for centuries.
These tribes had previously fought tirelessly again the Mexicans, and now were ready to fight the Americans. The Americans who were hunting off their game, and ravishing through their lands with their new railroad, western settlers, and Gold Rush prospectors.
One of the most significant attacks on the fort happened during the Civil War when Confederate forces were already targeting the New Mexico area and the natives saw their chance to also attack a vulnerable target.
Famous Colonel Kit Carson was called to fight in the U.S. Army stationed at the fort and led attacks against Apache, Navajo, Kiowa and Comanche tribes in the 1860s.
Battles against the Native Americans in the area seemed to be the final purpose of Fort Union. After the Red River War of 1874, the fort’s involvement of the Indian Wars ended and the site served little use, although it was not officially abandoned until 1891.
What is accessible and visible to visitors today are many sites that are still distinguishable for their purpose in the history of Fort Union.
The officer quarters were in a row of nine homes, the center home reserved for the post’s commander. These homes were assigned by rank with senior officers getting first choice.
The post commander’s house had eight rooms with its own cellar; it was one of the finest residences at Fort Union. One of the last buildings constructed was the military prison. What’s left of the original buildings now is the cell block itself, but in the 1800s, an adobe walls structure would have surrounded the prisoners which would have included murderers, deserters, and other criminals as well.
The Depot at Fort Union housed the hustle and bustle of visitors needing supplies or a stopping point. The site had storehouses for supplies which were locked up and guarded by soldiers at night.
A large Corral was central to the depot and housed the many livestock and horses needed for the Army. The site also housed a hospital with six wards and a capacity of 60 patients. It had a staff of eight and was actually one of the best hospitals in the West at the time.
An impressive site for the eventful time period of the American West, Fort Union served many important purposes along the famed Santa Fe Trail during its forty years of service.
