In 1941 Fort Missoula was turned over to the "Department of Immigration and Naturalization" for use as an Alien Detention Center for non-military Italian men. The fort held barracks for 1,000 men, officers' quarters, commissary, mess hall, laundry, guardhouse, and a recreation hall designed by Robert Reamer that held a basketball court, bowling alleys, dance hall, cocktail lounge, and restaurant.[1]
The Italians, who referred to Fort Missoula as Camp "Bella Vista" (beautiful view), worked in area farms, fought forest fires and worked in other Missoula industries before being released in 1944.[3]
Famed Italian actor Guido Trento (1892–1957), also known as Guy Trent and best known for his 1928 film Street Angel, was held at Fort Missoula and released in 1943 when Italy surrendered to the Allies. He later immigrated to the United States.
The Fort Missoula internment camp closed in 1944. By that time, most of the internees had been sent to other camps. Many were repatriated at the end of the war. Some Italians gained U.S. citizenship and stayed in the region.[1]
