Jaluit Atoll – Jaluit Atoll is located 243 nautical miles south of Kwajalein.  The atoll, including its principal island of Emidj, remained under Japanese control until it was surrendered on September 5, 1945.  Under the command of Rear Admiral Masuda, Emidj Island served as the main Japanese seaplane base in the Marshall Islands.  Like the other Japanese-held islands it was heavily bombed and effectively isolated from re-supply.  Defenses included 60 anti-aircraft guns and coastal defense guns.  By virtue of strict discipline and top soil shipped from Ponape which permitted the cultivation of vegetables, 67% of its garrison of 2,500 survived the war.
