defeat. After the battle, he was ordered to take his army east of the Mississippi River and join the Confederate army at Corinth, Mississippi, but he arrived too late to fight in the Battle of Shiloh. In Texas, Brigadier General Henry Sibley raised a brigade of cavalry and led it into the New Mexico Territory, intending to drive the remaining Union forces from it and advance into Colorado, capturing the gold and silver mines located in the territory. He fought the main Union force in the territory, commanded by Colonel Edward R.S. Canby, at the Battle of Valverde on February 17; although the battle was a Confederate victory, Sibley failed to force Canby to surrender. Instead, Sibley continued northward, leaving Canby in his rear. Continuing northward along the Rio Grande and the Santa Fe Tail, his brigade met a Union force, which included the 1st Colorado Infantry, at Glorieta Pass on March 28. The Confederates again drove the Union force from the field, but during the battle a Union detachment burned most of the Confederate supply train, along with most of their supplies. This meant that the Confederates had to retreat back to Texas, reaching it by mid-April, losing over 1,500 men out of an original force of 3,700 men.
