Mili Atoll
The Japanese navy developed military bases in the atolls in the early years of World War II. During this time, the military brought in several thousand Japanese, Okinawan and Korean labourers to undertake the construction of military facilities. Some Marshallese and Koreans reported of maltreatment by the Japanese authorities, and there was at least one case of revolt by both groups at Jelbon on Mili Atoll in which a hundred Japanese civilians and soldiers were killed. When American troops attacked the Marshall Islands between January and April 1944, Japanese troops evacuated many Japanese settlers and Korean labourers from the atolls. A few were reportedly killed in the ensuing air raids, while others who remained behind were captured as Prisoners of war after the Americans captured the atolls, together with some Japanese soldiers.
