The Jicarilla War began in 1849 and was fought between the Jicarilla Apaches and the United States military in the New Mexico Territory. Ute warriors also played a significant role in the conflict as they were allied with the Jicarillas. The war started when the Apaches and Utes began raiding against settlers on the Santa Fe Trail. Eventually, in 1853, the American army retaliated which resulted in a series of battles and campaigns that ended in 1854 when a large military expedition managed to quell most of the violence. However, some minor skirmishing continued into 1855.
