History

In 1854–1855, during United States Army expeditions into the New Mexico Territory following the Mexican–American War, the area around Eagle Spring was the site of a military engagement between U.S. troops and local Native American forces.

During an expedition commanded by General Persifor Frazer Smith, his stepson Frank Crawford Armstrong served as a volunteer civilian aide. Following a skirmish near Eagle Spring, Armstrong received recognition for gallantry in combat. In 1855, in recognition of his actions at the spring, Armstrong was awarded a direct military commission as a second lieutenant in the 2nd Dragoon Regiment, launching a military career that later saw him serve as a brigadier general in the Confederate States Army.
