'''Fort Yuma''' is the name of two historic forts in California and Arizona. Fort Yuma, of California in Imperial County, is located north across the [[Colorado River]] from [[Yuma, Arizona|Yuma]], where the Arizona Fort Yuma is sited.  Fort Yuma was on the [[Butterfield Overland Mail]] route from 1858 until 1861. The fort was abandoned May 16, 1883 and transferred to the [[Department of the Interior]]. 

The Fort Yuma Indian School and a [[Mission (Christian)|mission]] now occupy the site. It is the one of the [[Yuma Crossing and Associated Sites]] on the [[National Register of Historic Places]] in the [[Yuma Crossing National Heritage Area]].

==History==
===Pre-Civil War===
First established after the end of the [[Mexican-American War]] (1848), the fort was originally located in the bottoms near the [[Colorado River]], less than a mile below the mouth of the [[Gila River]]. It was constructed to defend the newly settled community of Yuma, [[New Mexico Territory]], located on the other side of the Colorado River, and the nearby Mexican border. 

In March 1851 the post was moved to a small elevation on the Colorado's west bank.  This site had been occupied by Camp Calhoun, named for Senator [[John C. Calhoun]]. It was established on October 2, 1849, by 1st Lieutenant Cave J. Couts, 1st Dragoons, for the boundary survey party led by 2nd Lieutenant [[Amiel W. Whipple]], Corps of Topographical Engineers. A ferry service, maintained by the soldiers for the survey party's convenience, also accommodated emigrants. 

Fort Yuma was established to protect the southern emigrant travel route to California and to attempt control of the territorial [[Quechan]] [[Native Americans in the United States|Native Americans]] (Yuma Indians) in their homeland, the surrounding {{convert|100|mi|km|sing=on}} area. Established by Captain [[Samuel P. Heintzelman]], [[2nd Infantry Regiment (United States)|2nd Infantry Regiment]], the fort was originally named 'Camp Independence.'<ref>{{cite web |last=Hart |first=Herbert |coauthors= |title=Historic California Posts: Fort Yuma |url=http://www.militarymuseum.org/FtYuma.html |date= |work=The California State Military Museum |publisher=California State Military Department |accessdate=18 August 2009}}</ref>

In March 1851, when the post was moved to its permanent site, its name was changed to '''Camp Yuma'''. A year later the post was designated '''Fort Yuma'''. In June 1851 the Army virtually abandoned the post because of the high costs incurred in maintaining it, and it was completely abandoned on December 6, 1851, when its commissary was practically empty of provisions. The post, however, was reoccupied by Captain Heintzelman on February 29, 1852.

It was difficult to supply the post during its early years.  Food supplies and construction materials were shipped by water from [[San Diego, California]], around the [[Baja Peninsula]] and up the [[Sea of Cortez]]—Gulf of California  to the mouth of the Colorado River at the  [[Colorado River Delta]] in [[Mexico]].  The work of transferring the goods to wagons at that point and hauling them across the [[Yuma Desert]] and [[Yuha Desert]] to Yuma was rigorous and time consuming.  Life at the post was harsh and the military's resolve to maintain a [[garrison]] here vacillated.  It was only two years later—in August 1852—that the temporary Camp Yuma became permanent Fort Yuma, and the Army resolved to stay for good.

===Civil War===
During the [[American Civil War]], the [[Union (American Civil War)|Union]] retained control of Fort Yuma when the [[1st California Infantry]] replaced the regular Army soldiers sent East in December 1861. [[Confederate]] forces consisting of Irish immigrants built a small fort just opposite California's Fort Yuma after U.S. troops had left the area. The two forts were captured by the Union [[California Column]] following their march across the [[Sonoran Desert]] in New Mexico and Arizona territory. They took the forts without a battle, as the Confederate troops retreated into Mexico before the Union forces arrived.<ref>{{cite web |title=Regiments of the California Volunteers in Federal Service, 1st Regiment of Infantry |url=http://www.militarymuseum.org/1stInfCV.html |date= |work=The California State Military Museum |publisher=California State Military Department |accessdate=30 July 2009}}</ref>  

The southern half of [[New Mexico Territory]] seceded, becoming the [[Confederate Territory of Arizona]] until 1863. The occupying Union forces established their own [[Arizona Territory]]. It served as the starting point when the California Column marched to western [[Texas]]. There was no battle action at the fort since the western U.S. was far removed from the Civil War.  .<ref>{{cite web |title=The California Column |url=http://www.militarymuseum.org/CaliforniaColumn2.html |date= |work=The California Military Museum |publisher=California State Military Department |accessdate=30 July 2009}}</ref>

===Post-Civil War===
Fort Yuma was closely associated with the [[Yuma Quartermaster Depot State Historic Park|Yuma Quartermaster Depot]] on the Arizona side of the river, which provided military supplies and personnel to posts throughout Arizona and New Mexico. The Quartermaster Depot operated between 1864 and 1891, though the Army terminated most operations there eight years earlier.

The depot was used by the Army to store and distribute supplies for all military posts in Arizona, Nevada, Utah, New Mexico and Texas during the [[American Indian Wars|Indian War period]]. A six-month supply of clothing, food, ammunition, and other goods was stored at the depot at all times. Supplies were brought from California by ocean vessels traveling around the Baja Peninsula to [[Port Isabel, Sonora|Port Isabel]] near the mouth of the Colorado River. There, cargos were transferred to river steamers and brought upstream to Yuma.

Supplies were unloaded at the depot and hauled up a track running from the dock to a storehouse. The depot quartered up to 900 mules and crews of teamsters to handle them. The [[Southern Pacific Railroad]] reached Yuma in 1877.  There was little need for the Quartermaster Depot and Fort Yuma, and they were abandoned on May 16, 1883.  The reservation was transferred to the [[Interior Department]] on July 22, 1884.

==Present day==
Fort Yuma is now within the [[Quechan]] [[Indian Reservation]].  Numerous historic buildings remain from the military period in the [[Yuma Crossing and Associated Sites]] in the [[Yuma Crossing National Heritage Area]]. The [[Yuma Territorial Prison]] and [[Yuma Quartermaster Depot State Historic Park]]s are in Arizona with buildings preserved or reconstructed, and with museums.
