Biography
Marshall describes Willhelm as a Clearfield County associate judge and former Pennsylvania militia officer arrested at midnight on December 24, 1864. He was confined at Harrisburg and Fort Mifflin. The narrative links prosecution to his chairing Democratic political meetings, reports a military sentence of two years and a $500 fine, and says severe illness led to his return home on parole and a later pardon by President Andrew Johnson.
