In July 1944, in the largest mass trial in Wyoming history, sixty-three Heart Mountain inmates were prosecuted after refusing to show up for their induction and convicted of felony draft evasion. A total of 300 draft resisters from eight WRA camps, including an additional 22 from Heart Mountain sentenced in a subsequent trial, were arrested for this charge, and most served time in federal prison. The seven older leaders of the Fair Play Committee were convicted of conspiracy to violate the Selective Service Act and sentenced to four years in federal prison. While the Poston concentration camp in Arizona had the highest number of resisters of any camp, at 106, Heart Mountain's 85 resisters from a much smaller population gave it the highest overall rate of draft resistance.
