Biography
William Evans is identified in Marshall, a twenty-three-year-old son of Robert A. Evans and nephew of Joseph K. Evans, among the Iowa civilians arrested around September 15, 1862 and confined at Des Moines, Newton and Camp McClellan. The account links the arrests to alleged disloyal speech or political association. The related Naylor narrative on pages 213-217 gives the group's release as December 9, 1862. Individual arrest-day precision is withheld where the account describes a night crossing calendar days. Source: John A. Marshall, American Bastile (1869), printed pages 421-425, https://archive.org/details/americanbastile00marsgoog/page/n436/mode/2up. Marshall is a partisan retrospective source; its allegations are attributed to the author.
