This weekend marks the anniversary of the Battle of Glorieta Pass (March 26-28, 1862), the decisive battle of the Civil War in New Mexico. While the battlefield has had historical markers since 1939, the stories you learn on the field have changed since the National Park Service took over in 1993. The landscape of interpretation tells not only the story of a battlefield, but the story of how we tell the story of a battlefield.
The battle marked the end of the Confederacy’s New Mexico campaign. Their plan for the campaign was pretty straightforward. Brigadier General Henry Hopkins Sibley and his Texan volunteers would advance up the Rio Grande from El Paso to Albuquerque and Santa Fe. From there, they would move eastward along the Santa Fe Trail, crossing the mountains at Glorieta Pass, and then turn north. After seizing the supply base at Fort Union, Sibley would take the mines of Colorado while disrupting federal communications with California, Nevada, and Oregon.

The key to the campaign was logistics. The Confederates would have a long supply train stretching back to El Paso, and they needed Fort Union’s supplies to make the plan work. The Union commander, Colonel Edward R. S. Canby, “lost” every battle, but won the campaign because he focused on the Confederate supply problem.
They fought various engagements up the Rio Grande before arriving at the Glorieta Pass region in March. On the third and decisive day, Canby split his forces. The larger part fought a delaying action near Pigeon’s Ranch. They gradually gave ground to Sibley’s Texans while remaining in good order astride the Santa Fe Trail.
Canby sent about two-fifths of his troops over Glorieta Mesa to the Confederate rear, where they found and destroyed the rebel supply train. Without supplies, the Confederates had to retreat to El Paso, using a difficult route through the mountains. Fewer than half found their way back.
When interpreting the battle, the National Park Service defines it as a tactical Confederate victory. After all, the rebels held the ground at the end of the day. The park also notes that “the Confederate victory was short lived” because Sibley no longer had his supply train.
That perspective is understandable. It rests on the fight around Pigeon’s Ranch, Glorieta Pass, and the Santa Fe Trail. That fight features two opposing forces, facing each other, trying to take or defend ground. It feels like a battle should feel—and, of course, it was a genuine battle.
Not only do visitors expect a battlefield to involve military units moving around a battlefield, but many military historians would also tell the story exactly that way. We see that perspective in a lesson plan the park developed for students: “the Battle of Glorieta Pass represented the high-water mark for a bold Confederate offensive into Union Territory on the western frontier. Here volunteers from Colorado clashed with tough Texans intent on conquering New Mexico.” Tough soldiers fought bravely on both sides.

A focus on brave soldiers also produced the first interpretation on the site. In 1866, New Mexico recognized its soldiers on one side of an obelisk in downtown Santa Fe, honoring “the heros of the Federal Army who fell at the battles of Cañon del Apache and Pigeon’s Rancho (La Glorieta), fought with the Rebels March 28, 1862.” Protestors tore the obelisk down in 2020, for reasons unrelated to Glorieta Pass. That’s a story for a different time.

It took Colorado even longer, since its State Historical Society erected a Colorado monument only in 1993.
Remembering battlefield bravery motivated park advocates. The Glorieta Battlefield Preservation Society, a group of regional Civil War reenactors, worked to preserve the site, which had remained in private hands. The Council of America’s Military Past, the United Daughters of the Confederacy (UDC), and other military heritage groups worked with them to convince Congress to establish the Glorieta Battlefield Unit of Pecos National Historical Park.
The NPS then began to update this landscape of memorialization it had inherited. In addition to leaving the stone memorials in place, the historical park installed a collection of modern interpretive signs on the Glorieta Battlefield Trail. The trail makes a lovely hike today.

Park advocates helped fund the new interpretive trail and most of the signs the visitor sees. Signs funded by Texan and Confederate groups highlight the bravery of Sibley’s troops. Signs placed by the State of New Mexico highlight the role of Hispanos, New Mexican Volunteers, and U.S. Regulars. While they also discuss how the Union soldiers burned the Confederate wagons, those signs place greater weight on the fight around Pigeon’s Ranch at Glorieta Pass. Again, the action on a conventional battlefield seems more important.
Taken as a whole, those signs tell a richer version of the story than the stone markers do, and a more accurate one. Still, one might go further, and turn current interpretation on its head. By dividing his force in the face of the enemy, General Canby had clearly decided to make the wagon train central to his battle plan. The 750 troops near Pigeon’s Ranch needed only to protect Union lines of communication behind them while the other 500 men circled behind Confederate lines. On this alternative perspective, the ground of Glorieta Pass mattered much less than the supply train—making this a decisive Union victory.
A second feature of the campaign also contributed to the Union victory. Well before the battle itself, the Union had won the battle for the hearts and minds of New Mexico’s citizens. The Confederates supposed that the locals, having become involuntary subjects of the United States in 1846, might welcome “liberation.” The rebels hoped they could rely on those locals for some supplies along the way. As it turns, New Mexicans liked Texans even less than they liked gringos, and were not inclined to help out.
The battle for hearts and minds also brought New Mexican volunteers to Canby’s side at Glorieta. Lt. Colonel Manuel Chavez, who led those volunteers, had the local knowledge to guide the Union forces over the mesa to the Texans’ wagons. The Confederates had no good local sources of supplies once the wagons were gone.
In short, the battle in Glorieta Pass is less important than both the supply wagons and the contest for local political support. Bravery, heroism, perseverance, and determination are all important military qualities—but don’t forget to make friends and burn the wagon train.
