The Battle of Valverde was a major New Mexico engagement fought near Fort Craig in 1862 (see http://en.wikipedia.org/wiki/Battle_of_Valverde).
Groups of Federal and Confederate reenactors from New Mexico and neighboring states will set up period camps open to the public, explain and reenact the battle (with artillery, cavalry, and infantry), and give historical presentations at Escondida.
Related activities include a Victorian ladies Tea and Fashion Show and Fandango with period band, all held in nearby Socorro at the historic Garcia Opera House. (There is a charge for these two particular events.)
The re-enactment event is FREE to the public and makes a great family outing. NM school kids usually study the Civil War in the 8th grade, and it could be a fun extra-credit opportunity and chance for them to “see history come-alive.” Too often youngsters feel book-taught history to be dry or boring. Definitely bring your cameras. Visitors are encouraged but not required to wear anything Victorian era; it adds to the fun.
