When attempting to confront hostile Apache guerrillas in New Mexico between 1879 and 1881, the US Army encountered a style of warfare which took merciless advantage of its weaknesses. However, the failure of the army to defeat its enemies can be only partially ascribed to this factor. Its efforts were further hampered by the political context within which it had to operate. Nevertheless, these factors occasionally worked in the army’s favour. When these political constraints did undermine efforts to defeat the Apaches, the US Army demonstrated that it was sometimes capable of turning this political context to its advantage.
