Description: Glorieta Pass was a strategic location, situated at the southern tip of the Sangre de Cristo Mountains, southeast of Santa Fe, and on the Santa Fe Trail. In March 1862, a Confederate force of 200-300 Texans under the command of Maj. Charles L. Pyron encamped at Johnson’s Ranch, at one end of the pass. Union Maj. John M. Chivington led more than 400 soldiers to the Pass and on the morning of March 26 moved out to attack. After noon, Chivington’s men captured some Rebel advance troops and then found the main force behind them. Chivington advanced on them, but their artillery fire threw him back. He regrouped, split his force to the two sides of the pass, caught the Rebels in a crossfire, and soon forced them to retire. Pyron and his men retired about a mile and a half to a narrow section of the pass and formed a defensive line before Chivington’s men appeared. The Yankees flanked Pyron’s men again and punished them with enfilade fire. The Confederates fled again and the Union cavalry charged, capturing the rearguard. Chivington then retired and went into camp at Kozlowski’s Ranch. No fighting occurred the next day as reinforcements arrived for both sides. Lt. Col. William R. Scurry’s troops swelled the Rebel ranks to about 1,100 while Union Col. John P. Slough arrived with about 900 men. Both Slough and Scurry decided to attack and set out early on the 28th to do so. As Scurry advanced down the canyon, he saw the Union forces approaching, so he esta...

The Battle of Glorieta Pass, fought from March 26 – 28, 1862 in northern New Mexico Territory, was the decisive battle of the New Mexico Campaign during the American Civil War. Dubbed the "Gettysburg of the West" by some historians, it was intended as the killer blow by Union forces to halt the the Confederate invasion of the West along the base of the Rocky Mountains. It was fought at Glorieta Pass in the Sangre de Cristo Mountains in what is now New Mexico, and was an important event in the history of the New Mexico Territory in the American Civil War.

There was a skirmish on March 26 between advance forces from each army, with the main battle occurring on March 28. Although the Confederates were able to push the Union force back through the pass, they had to retreat when their supply train was destroyed and most of their horses and mules killed or driven off. Eventually, the Confederates had to withdraw entirely from the territory back into Texas. Glorieta Pass thus represented the "high water mark" of the campaign.

New Mexico Campaign

The Confederacy had organized the Confederate Arizona Territory in 1862, a claim that included the southern halves of modern Arizona and New Mexico, after secession moves by residents. The territory had its capital at Mesilla, outside modern Las Cruces. The strategic aim was to capture the gold and silver mines in California and Colorado Territory and the ports in southern California.

The commanders of the New Mexico Campaign were the Confederate Brigadier General Henry Hopkins Sibley, and the Union Colonel Edward Canby. Sibley, whose mission was to capture Fort Craig, outmaneuvered Canby at the Battle of Valverde in February and drove Canby back to his fort, but failed to force Canby's surrender. Instead, Sibley bypassed the fort, and advanced up along the Rio Grande Valley to seize Santa Fe on March 10. Canby remained at Fort Craig to cut Sibley's logistical support from Texas and to await further reinforcements be...
