On June 22, 1918, a locomotive pulling 20 empty passenger cars rear-ended the Hagenbeck-Wallace circus train near Hammond, Indiana. The wreck and subsequent fire—likely ignited by the oil lamps in the circus train’s wooden sleeping cars—resulted in 86 deaths and 127 injuries. Most of the dead were buried five days later in a nearby cemetery in a section called Showmen’s Rest, which had been purchased by the Showmen’s League of America just months earlier.
