There was some Civil War action going on...

to commemorate the battle at Glorieta Pass.

Valverde 21 February, 1862
Glorieta 28 March, 1862

"Civil War battles occurred in New Mexico that were little noted in the 'States' (New Mexico was then a Territory). In the view of many historians, however, these battles were important in preserving the Union because they ended the attempt by the Confederacy to capture the West (New Mexico, Arizona, California, Colorado), its people, and its vast resources. Two of these battles were at Valverde, about 29 miles south of Socorro, and at Glorieta, a few miles east of Santa Fe." From New Mexico in the Civil War
