Arizona was thought to be important to the role of the
New Mexico Territory in the American Civil War primarily because it offered Confederate access to California. Consequently, it was the scene of several important battles in the war's
Trans-Mississippi Theater. In July 1861 a force under Lieutenant-Colonel John R. Baylor arrived in
El Paso, Texas across the border from Mesilla. With support from the secessionist residents of Mesilla, Baylor's 2nd Texas Mounted Rifles entered the territory and took a position in the town on July 25. Union forces under Major Isaac Lynde at nearby
Fort Fillmore prepared to attack Baylor. On July 25 the two armies met outside of town at the Battle of Mesilla in a brief engagement in which the Union troops were defeated. Major Lynde then abandoned
Fort Fillmore and began a march north to join the troops at
Fort Craig under Colonel
Edward R. S. Canby. However, his retreat came to a halt in severe heat and was overtaken by Baylor. Lynde surrendered his command without a shot fired at San Augustine Springs, in the
Organ Mountains. On August 1, 1861, the victorious Baylor proclaimed the existence of a Confederate Arizona Territory, which comprised the area defined in the Tucson convention the previous year. He appointed himself as permanent
governor. Among his cabinet members was the Mesilla attorney
Marcus H. MacWillie, who served as the territorial
attorney general. The next month, Baylor's cavalrymen under
Bethel Coopwood, marched north from
Camp Robledo along the Rio Grande and surprised a Union force of New Mexican militia cavalry in a
small engagement west of the Rio Grande at the village of
Canada Alamosa, ending with another Confederate victory and the capture of 25 men of that unit including its commander. The next day after disarming and paroling the captured New Mexican enlisted men, Coopwood retired southward along the west bank of the river with the two captured Union officers and an NCO to a camp 15 miles to the north of
Fort Thorn. There a Union column of Mounted Infantry sent to relieve the New Mexican militia force caught up with Coopwood, and
skirmished for a few hours with the Confederates until their ammunition was depleted, forcing the Mounted Infantry to retire northward to their base at
Fort Craig. The proposal to organize the Confederate Territory of Arizona was passed by the Confederate Congress in early 1862 and proclaimed by
President Jefferson Davis on February 14, 1862. Coincidentally, Arizona statehood was approved exactly fifty years later on February 14, 1912. in Tucson. Efforts by the Confederacy to secure control of the region led to the New Mexico Campaign. Baylor sent
Company A, Arizona Rangers to Tucson to protect the population from the Apache and
delay the advance of Union troops from Fort Yuma. In 1862 Baylor was ousted as governor of the territory by President Davis, and the Confederate loss at the Battle of Glorieta Pass forced Confederate retreat from the territory. On March 30, Union forces fought a smaller engagement against a detachment of
Company A, Arizona Rangers, a Confederate force destroying supply depots along the
California Column route of advance on the
Gila River, 80 miles east of its base at
Fort Yuma. This skirmish, known as the
Battle of Stanwix Station, was the westernmost engagement of regular forces in the Civil War, and successfully delayed the advance of the California forces. The following month a small picket troop of the Rangers north of Tucson fought with an equally small Union cavalry patrol from the California Column in the so-called
Battle of Picacho Pass again delaying the advance of the California Column to Tucson. By July 1862, Union forces of the California Column were approaching the territorial capital of Mesilla from the west but severe flooding of the Rio Grande barred their way and they had to divert north to Fort Thorn and the
San Diego Crossing and wait two weeks for the water to fall enough for a crossing. With Canby advancing down the east bank of the Rio Grande and the loss of control of the countryside to New Mexican guerillas after the
Second Battle of Mesilla the Confederates abandoned Mesilla and retreated south to
Franklin, Texas. In 1862 the
California Column volunteers who fought at Stanwix Station and Picacho Pass fought at the
Battle of Apache Pass against 500
Apaches. The battle is considered part of the American Civil War. There were also several engagements between
Apaches and Confederates. The
Battle of Dragoon Springs marks the only known Confederate combat deaths in the modern confines of Arizona. Other engagements include the
Siege of Tubac, the
Battle of Cookes Canyon, the
Battle of the Florida Mountains, the
Battle of Pinos Altos and a number of other smaller skirmishes and massacres. The territorial government relocated to Franklin, then with Confederate military units retreated to
San Antonio abandoning
West Texas. For the rest of the war, California Column troops controlled all of Confederate Arizona, Franklin and
Fort Quitman in West Texas. The government in exile remained in Texas for the duration of the war, although MacWillie continued to represent the territory in the
First and
2nd Confederate States Congresses. Minor resistance in Arizona continued at the partisan level, and Confederate units under the banner of Arizona fought until the end of the war in May 1865. == See also == •
