In New Mexico, Texas and Colorado units clash in the Glorieta Pass at Apache Canyon
After occupying the territorial capital of Santa Fé two weeks before, Confederate Brigadier General Henry H. Sibley sought to continue his invasion of New Mexico with an advance against the Union strongpoint at Fort Union. An advance force of Texas cavalry made its way to the Glorieta Pass but were attacked in their camp near Apache Canyon in the morning by Union troops under Major John M. Chivington. After fierce fighting, the Texans fell back and both sides awaited reinforcements. The full battle of Glorieta Pass took place two days later. (By John Osborne)
