From the 1840s onward, United States military forces clashed with the Apache, a group of Native American peoples associated with the southwestern part of North America.US territorial expansion and conflict – first with Mexico and then during the Civil War – led to an escalation of hostilities that culminated in the defeat of the Apache leader Geronimo in 1886, although fighting continued into the 20th century. In this study the clashes at Cieneguilla (1854), First Adobe Walls (1864), and Cibecue Creek (1881) are assessed in detail.Fully illustrated and featuring contemporary accounts and specially commissioned artwork, this history examines exactly how the Apache were able to pose such a grave threat to US forces and how their initial advantages were gradually negated by the cavalry. Examining the tactics, equipment and training available to each side over four decades of evolving conflict, this is an eye-opening combatant's eye view of one of history's most intriguing campaigns.
