  • 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 camped 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 26th moved out to attack.

  • The two forces engaged in the afternoon, with Chivington’s men flanking the Confederate troops and capturing the rearguard. Chivington retired and camped at Kozlowski’s Ranch.

  • Reinforcements arrived the next day with Lt. Col. William R. Scurry’s troops increasing the Confederate forces 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.

  • The fighting continued the next day with Scurry's Confederates repulsing the Union attack and driving Slough back to Kozlowski’s Ranch.

  • Scurry thought he had won the battle, however, he discovered that Chivington’s men had destroyed all Scurry’s supplies and animals at Johnson’s Ranch.

  • Although Scurry had won the day he was forced to retreat to Santa Fe and then to San Antonio, Texas.

  • The Union victory at Glorieta Pass was the turning point of the war in the New Mexico Territory and stopped Confederate incursions into the Southwest.
