The California Column was a force of Union volunteers sent to Arizona and New Mexico during the American Civil War. The command marched over 900 miles from California through Arizona and New Mexico Territory to the Rio Grande and as far east as El Paso, Texas, between April and August 1862.
The "California Column" originally consisted of ten companies of the 1st California Infantry, all five companies of the 1st Regiment California Volunteer Cavalry, Company B, 2nd Regiment California Volunteer Cavalry and Light Battery A of the Third U.S. Artillery. This command contained 1500 well drilled and disciplined men. Later on, Lieutenant Colonel George W. Bowie's 5th California Infantry was added, bringing the total strength of the Column to 2350 men.
The objective of their commander, Colonel James Henry Carleton (promoted to brigadier general while the column was en route) was to drive Confederate troops out of New Mexico, which they had occupied the previous year. The soldiers of the California Column, both infantry and cavalry, often traveled by foot wearing woolen uniforms in the desert heat. They started out from Fort Yuma along the Colorado River. Much like the Confederate Army of New Mexico (also known as the Sibley Brigade), which had entered New Mexico from Texas in December 1861, they traveled in small groups at intervals of a few days so men and horses would not exhaust the springs and wells along the way. They followed the established route of the Butterfield Overland Mail, which had ceased operation the year before. The mail posts were filled with food and grain which Union spies had stockpiled there before the invasion.
Arizona Confederate volunteers, the Company A, Arizona Rangers, arrested the Union Army agent, Ammi White, destroyed White's flour mill at Casa Blanca and supplies of food and fodder being gathered there and at other stage stations along the Column's route between Fort Yuma and Tucson. This slowed Carleton's progress. Most of Carleton's attempts to send messages to General E. R. S. Canby, the Union's departmental commander of New Mexico, were intercepted, and one patrol sent to meet White was captured by Confederates at White's Mill at the Pima Indian villages.
During their advance the California Column engaged the Confederates in two small skirmishes. The first was a skirmish with Confederates attempting to burn forage gathered at Stanwix Station near the end of March 1862. The second clash came in mid-April when the column marched on Tucson from Casa Blanca, at Picacho Pass. Their subsequent rapid approach to Tucson nearly trapped the Confederate rearguard.
It was not until late June that a scout named John W. Jones was able to outrun pursuing Apaches and get a message to Canby: "The Column from California is really coming." On the march to the Rio Grande, 140 men of Company E, 1st California Infantry, and Company B, 2nd California Infantry, fought the famous Apache leader Cochise at Apache Pass in July. By the time the California Column reached the Rio Grande, the Confederates had already retreated to Texas. Carlton followed them into West Texas, capturing Franklin, Texas and advancing as far as Fort Quitman.
Most of their service after that would be as garrisons in West Texas to prevent the return of the rebels. Their main activity was as garrisons of the settlements and forts in New Mexico Territory, and in fighting against the Apaches and Navajo.
