He led numerous raids as well as resistance to United States and Mexican military campaigns in the northern Mexico states of Chihuahua and Sonora, and in the southwestern American territories of New Mexico and Arizona. Unwilling to be confined to the reservations that they had been put in, Geronimo and his fellow Chiricahua Apaches broke out from their constraints and fled south towards the Mexican border. And so in 1883 Geronimo was on the warpath again. But this time he met his fighting match in General George Crook. Captain John Bourke was an aide to General Crook and so therefore had the opportunity to witness and record every action that was made throughout the campaign. Yet, this is not merely the account of a military campaign against rebellious Native Americans as Bourke also provides a sympathetic overview of the culture and customs of the Chiricahua Apaches.
