The Battle of Badung Strait was a naval battle of the Pacific War, fought on the night of 25/26 February 1939 in Badung Strait (not to be confused with the West Java city of Bandung) between an Allied fleet under the command of Karel Doorman and the Imperial Japanese Navy. In the engagement, the four Japanese destroyers defeated an Allied force that outnumbered and outgunned them, escorting two transports to safety and sinking the Dutch destroyer Piet Hein. The battle demonstrated the Japanese Navy's considerable superiority over the Allies in night fighting throughout the war.
