Mark Costin on “Confederate Campaign to Invade New Mexico, Battles of Valderde and Glorieta Pass”

The New Mexico campaign of 1862 was the only major Confederate campaign to expand the boarders of the Confederacy. Confederate Brigadier General Henry Hopkins Sibley invaded the northern New Mexico Territory in an attempt to gain control of the Southwest, including the gold fields of Colorado and the ports of California. The talk will cover the campaign with particular attention to the two major battles of the invasion, the Battles of Valderde and Glorieta Pass.
