Ball’s interviews — collected and published in books including In the Days of Victorio (1970) and Indeh: An Apache Odyssey (1980) — constitute one of the most important primary sources for the Apache perspective on the events of the late nineteenth century.

Among the people Ball interviewed was James Kaywaykla, who had been a child during the Victorio War and the subsequent resistance and who had survived the prisoner years to live into the mid-twentieth century.

Kaywaykla’s accounts, filtered through Ball’s transcription and editing, provide some of the most detailed descriptions of Lozen that exist.

He had known her as a child, had witnessed her actions, and had been told about her by the adults around him.

The specific descriptions of Lozen’s power to locate enemies, her exceptional riding, her role as Victorio’s right hand — these come primarily from the accounts that Ball collected.
