The 1860s may well have been the bloodiest decade in New Mexico history.  First there was Jefferson Davis’ pet project, a Confederate invasion of the territory… and then, after the rebels had been defeated, the Union Army turned on Native Americans with resultas as cruel as they were ineffectual. Megan Kate Nelson, author of The Three-Cornered War: The Union, The Confederacy and Native People in the Fight for the West tells the story in depth on HERE & THERE.
