I found a site for Fort Craig at
Fort Craig was a U.S. military outpost from 1854 to 1885. The Civil War battle of Velverde was fought nearby by soldiers from the fort.
Two of my 2nd Great Grandfathers served at Fort Craig in the mid-1800s, Philip Bourguignon and Samuel Zimmerly. From what I can gather, Philip Bourguignon had been discharged from the army prior to the battle. Samuel Zimmerly was part of the California Column which entered New Mexico in response to the Confederate invasion. He did not take part in any Civil War battle either.
