After the Treaty of Guadalupe Hidalgo ended the Mexican-American War in 1848, New Mexico officially became a part of the United States. Americans started moving west to try and stake a claim in this new territory, but were often met with hostility by Indians trying to protect what they believed belonged to them. In response, the U.S. government built Fort Union at the main junction on the Santa Fe Trail. The original fort was good enough for that purpose, but a second, stronger, fort was built during the Civil War and a third fort soon replaced the second. The fort served two main purposes which were independent of each another - one being a military post and the other, a quartermaster depot. The depot was the supply hub for the government in the southwest and received hundreds of wagonloads of supplies daily to support 46 regional posts. There was also an arsenal on the base which could have also been seen as a separate entity as it had its own commander and staff. In addition, the base hospital provided the best medical care for hundreds of miles around. Fort Union served as the jumping-off point for Union forces on their way to fight at Glorieta Pass, the last Civil War battle fought in New Mexico. After the Civil War, African-American soldiers with the 57th U.S. Colored Infantry arrived at Fort Union and later the 9th U.S. Cavalry, remembered today as the Buffalo Soldiers, would join them. When trains started rumbling across the country at the end of the 19th century, Fort Union became obsolete and was decommissioned in 1891. The last soldiers left on May 15th of that year. In 1954, it became Fort Union National Monument and its history is now interpreted by the National Park Service.
Most of the fort was built of adobe which, without regular maintenance, will melt back into the desert. Some exceptions were the stone jail and the brick chimneys which provide a glimpse into what Fort Union once was. This park site doesn’t get many visitors, but it’s a fascinating place to learn about the Santa Fe Trail and early American history in the New Mexico Territory. I hope you enjoy these photos from fascinating Fort Union National Monument.
