Description: An epic labor strike that devastated Michigan's Copper Country in 1913 haunts the American labor movement to this day. Among the notable elements of that strike was the death of 73 children at a union Christmas party, a tragedy immortalized by Woody Guthrie in his ballad "1913 Massacre," performed in the film by Steve Earle. The event remains the deadliest unsolved manslaughter in U.S. history.
