The Battle of Tarakan took place on 11–12 January 1942, a day after the Empire of Japan declared war on the Kingdom of the Netherlands. Although Tarakan was only a small marshy island off northeastern Borneo in the Netherlands East Indies (today's Indonesia), its 700 oil wells, refineries, and airfield made it a crucial objective for Japan in the Pacific War.
