More than 750 young men and women incarcerated at the Heart Mountain Relocation Center during World War II left the camp to serve in the U.S. Armed Forces, despite being forced by the government to live in wooden barracks surrounded by barbed wire. In the summer of 1944, the camp's United Service Organization sponsored construction of a servicemen's roll call panel that was placed in front of the administration building by the camp's engineering department. The original list included all servicemen and women whose families were incarcerated at the camp, including those already in service before the start of the war, people from families transferred to Heart Mountain from other camps, and Caucasian employees of the center who left to serve in the military. Although the full original list of names did not survive, it was recreated using the Heart Mountain Relocation Center census from the National Archives, the camp newspaper The Heart Mountain Sentinel, and information from family and friends of former inmates. The replica honor roll and new flag pole were provided and installed by the Heart Mountain, Wyoming, Foundation with funding solely from private donors, including former inmates, their descendants, and Wyoming residents, and the list was considered as accurate as possible in 2002, with names able to be added later if shown to belong on the honor roll.
