Eventually, the camp held more than 4,000 Okinawans, Italians, German Americans, Koreans, and Taiwanese as well. The first Korean prisoners were believed to have arrived in late 1943 or early 1944; they comprised non-combatant laborers captured during the Gilbert and Marshall Islands campaign. A Korean-language newsletter, the "Free Press for Liberated Korea" (자유한인보), was written and mimeographed by three Korean soldiers of the Japanese Imperial Army interned in the camp; it continued publication until December 1945. Beginning in 1943, the Japanese American internees were either released on parole or transferred to Department of Justice camps on the mainland. After the third transfer in November 1944, twenty-one U.S. civilians remained in Honouliuli and the camp served primarily as a holding center for POWs. At the end of the war, some 4,000 POWs were confined at Honouliuli; repatriation efforts began in December 1945 and continued into 1946.
