The Comanche–Mexico Wars was the Mexican theater of the Comanche Wars, a series of conflicts from 1821 to 1870. The Comanche and their Kiowa and Kiowa Apache allies carried out large-scale raids hundreds of miles deep into Mexico.Smith, Ralph A. "The Comanches' Foreign War." Great Plains Journal. Vol. 24–25, 1985–1986, p. 21 The raids were stimulated by the desire of Comanches to accumulate wealth through plunder, principally horses, mules, and Mexican captives for ransom or slaves who became integrated into the tribe. The raids escalated proportionally to Mexico's inability to defend its citizens during the turbulent years after it gained independence in 1821 and a large and growing market in the United States for stolen Mexican horses and cattle.Delay, Brian. "Independent Indians and the U.S. Mexican War." The American Historical Review, Vo. 112, No. 1 (Feb 2007), , p. 35

The Comanche launched their raids from Texas, usually in autumn. In Texas, a full moon in September was known as a "Comanche Moon" as the mounted Comanche raiders rode south to Mexico at night by the light of the moon. Comanche raids usually consisted of 200 to 800 warriors. The raiders penetrated into Mexico south of the Rio Grande. Forty-four raids are recorded from 1831 to 1848. During that period, the Comanche killed more than 2,600 Mexicans, captured more than 800 people, and stole more than 100,000 head of livestock. The Mexican defenders killed more than 700 Comanches.

When the US Army invaded northern Mexico in 1846 during the Mexican–American War, the region was devastated. After the mid-1850s Comanche raids into Mexico declined in size and intensity. Comanche power diminished due to a cholera epidemic in 1849, encroachment on their lands in Texas by white settlers, the near-extinction of the bison which was their principal source of food, and the U.S. Army's campaigns against them. The last known Comanche raid into Mexico was in 1870. In 1875, the U.S. army defeated the Comanches and forced them to live on a reservation in Oklahoma.

Background In the words of U.S. Army General James Wilkinson, the Comanche were "the most powerful nation of savages on this continent."DeLay, Brian, The War of a Thousand Deserts. New Haven: Yale U Press, 2008, p.15 That power would be amply demonstrated as the United States and the newly independent country of Mexico contested ownership of Texas and much of the area now known as the southwestern U.S. The Comanche considered themselves owners of a block of land that stretched from the Arkansas River in Colorado to near the Rio Grande in Texas. In the early nineteenth century, perhaps 20,000 Comanche shared this land, called Comancheria, with 2,000 Kiowa and 300 Plains Apache (Kiowa Apache). They sometimes granted hunting rights to other tribes, such as the Wichita.Hamalainen, Pekka, The Comanche Empire. New Haven: Yale U Press, 2009, pp.179

The Comanche came to the attention of the Spanish in the province Santa Fe de Nuevo México (New Mexico) in 1706. Conflicts led to punitive expedition by Juan Bautista de Anza in 1779, resulting a battle in eastern Colorado in which the Comanche leader Greenhorn was killed. Peace treaties were concluded with their eastern bands by Pedro Vial and Francisco Xavier Chaves in 1785 and their western bands in 1786. The Spanish welcomed the Comanche as an ally against the Apache, forgave their transgressions, traded manufactured items and corn to them for horses, captives, and buffalo meat, and showered them with gifts. The mutually beneficial relationship between Spaniards and Comanches began to come apart in 1821 when Mexico won its independence from Spain. The new country had no resources to continue paying tribute to the Comanche and was embroiled in domestic political disputes rather than paying attention to troubles on its northern frontier.Hamalainen, pp. 221–223

The Comanche, for their part, in the 1820s and 1830s were under intense pressure from competitors. The Osage were formidable enemies. The expulsion by the U.S. and the migration west to Oklahoma by the Five civilized tribes, the Shawnee, and the Delaware brought them into competition with the Comanche on the Great Plains. The Comanche lost several battles with the Osage and the eastern Indian tribes who were generally better armed.Hamalainen, pp. 304-205

Anglo-Americans arrived on the heels of the eastern Indians. Traders journeyed in increasing numbers along the Santa Fe Trail across the northern border of Comancheria and Anglo hunters depleted the buffalo herds in that vicinity. Northern Plains Indians such as the Cheyenne and Arapaho pressed south, drawn by Bent's Fort and the herds of feral horses on the southern Great Plains. They were equal to the Comanche in their skills as mounted warriors.DeLay, Brian. "The Wider World of the Handsome Man: Southern Plains Indians invade Mexico, 1830–1848." Journal of the Early Republic. Vol, 27, NO. 2, Spring 2007, p. 90–95 Comanche numbers were also declining from epidemics of European diseases. Comanche interests dictated peace with the Mexicans so threats from other Indians and Anglo-Americans could be addressed. On several occasions in the 1820s the Comanche attempted to obtain Mexican military assistance to repel the Indian invaders of their land, but their requests were denied. As they had often aided the Mexicans in the past to fight their mutual enemies, the Apache, the Mexican government's denial undermined the Comanches' commitment to peace with Mexico. However, as an inducement to peaceful relations, Mexican provincial governments made haste to strengthen trade ties with the Comanche in the early 1830s.DeLay (2008), 62–64

An important factor encouraging Comanche raids of Mexican ranches was the huge demand for horses and mules by the Anglo-Americans now flooding into lands west of the Mississippi River.Hamalainen, p. 194 The Comanches could meet that demand by breeding and selling horses from their herds, capturing and training wild horses from the herds in Comancheria, or raiding Mexican ranches and taking horses. The last was often the preferred option of ambitious young men striving to become rich in a pastoral society. Comanche raids for horses in Texas and along the Rio Grande in Mexico increased in 1831 and afterwards. A young, poor Comanche man could better his circumstances—albeit at risk to his life—by raiding for horses and human captives. The wealth he obtained would enable him to buy a Comanche wife—or he might find a first, second, or third wife among the captives.Brooks, James F. Captives and Cousins: Slavery, Kinship, and Community in the Southwest Borderlands. Chapel Hill: U of NC Press, 2002, pp. 178–179

The Mexican government accused the U.S. and independent Texas of encouraging Comanche raids, especially by trading guns to the Comanche in exchange for horses. In 1826, a Mexican official appealed to the U.S. to stop the "traders in blood who put instruments of death in the hands of those barbarians."Weber, David J. The Mexican Frontier, 1821–1846, Albuquerque: U of NM Press, 1982, p. 95 In 1835, the state of Chihuahua, ravaged by Apache as well as Comanche raids, offered a bounty of 100 pesos (about U.S.$100) for each scalp of a hostile Indian man and lesser amounts for women and children. Anglo American and Indian, primarily Delaware and Shawnee, scalp hunters killed many Apache and peaceful Indians for the bounty over the next few years, but apparently had little success in hunting down and killing Comanches. xroads.virginia.edu], accessed Sept 2, 2010

Comanche diplomacy

The Comanche resolved most of the challenges facing them in the 1830s with adroit diplomacy. Their strategy was flexible. With New Mexico, a Mexican province to their west, they enjoyed friendly trading relations. New Mexico was more of an asset than a threat to the Comanches and the New Mexicans avoided war with the Indians. In 1841 Governor Manuel Armijo was ordered by the Mexican central government to join a military campaign against the Comanche, but Armijo declined. "To declare war on the Comanches would bring complete ruin to the Department of New Mexico." In 1844, New Mexican officials learned of but did nothing to prevent a Comanche raid on Chihuahua.Weber, p. 114–115

With their western flank secured by an unthreatening New Mexico, the Comanche dealt with rivals on their northern and eastern borders. In 1835, they met with a delegation of U.S. soldiers and eastern Indians in the Wichita Mountains of Oklahoma and concluded a peace agreement. The agreement permitted eastern Indians and Anglo-Americans to hunt on Comanche lands and did not restrain the Comanche and their Kiowa and Wichita allies from making war on Mexico.Hoig, Stan, Beyond the Frontier: Exploring the Indian Country. Norman: U of OK Press,1998, p. 185 With their eastern flank secured by the treaty with the U.S., the Comanches next concluded a peace agreement in 1840 with the Southern Cheyenne and Arapaho pressing on them from the north. It was highly favorable to the Cheyenne and Arapaho. They were permitted to reside and hunt on the buffalo and horse-rich Comanche lands and, in addition, the affluent Comanches gave them gifts, including as many as six horses to every Cheyenne and Arapaho man.DeLay (2008), p. 80 The Comanche welcome to the southern bands of these two tribes, numbering more than 2,500, was both an acknowledgment that they were formidable rivals and also that the Comanche were short on men and resources to maintain their control over Comancheria.Hamalainen, pg. 177-179

South and southeast of Comancheria were the fast-growing Anglo-American communities in the Mexican territory of Texas. In the 1820s and 1830s most Comanche raids were in the southern parts of Texas and affected the largely Hispanic population around San Antonio, Laredo and Goliad.Hamalainen, 198-199 After the Texas Revolution asserting independence from Mexico in 1836, the Comanche had to deal with the new Republic of Texas. Texas's first President, Sam Houston, was knowledgeable about Indians and favored a policy of accommodation with the Comanche.Hamailainen, pp. 201, 215-217

Continued Comanche raids led to the election in 1838 of Mirabeau B. Lamar who favored a more aggressive approach. The massacre of 35 Comanche chiefs attending a peace conference in San Antonio in March 1840 set off a series of bloody reprisals and battles. Hundreds of Comanches descended upon and destroyed the towns of Victoria and Linnville in 1840 (see Great Raid of 1840). Although the Texans demonstrated they could punish the Comanche (See Battle of Plum Creek) military campaigns emptied their treasury and Texas became more accommodating. (See Texas-Indian Wars) In 1844, the Texans and the Comanches came to an agreement which recognized Comanche lands and left Comancheria intact.Hamalainen, 228

What the agreements with the United States and neighboring tribes and a hiatus in the struggle with Texas accomplished was to free up the Comanche to make unrestrained war on the Mexican provinces south of the Rio Grande. As the 1830s demonstrated, the Texans, the United States, and neighboring tribes all had the ability to invade Comancheria and attack the Comanche homeland. Mexico, by contrast, was rich in horses and unable to counterattack due to distance and the fact that, after 1836, any Mexican military offensive against
