The Battle of the Java Sea was a decisive naval battle of the Pacific campaign of World War II, that sealed the fate of the Netherlands East Indies. Allied navies suffered a disastrous defeat at the hand of the Imperial Japanese Navy, on 27 February 1942, and in secondary actions over successive days. The American-British-Dutch-Australian Command (ABDA) Strike Force commander—Rear-Admiral Karel Doorman—was killed. The aftermath of the battle included several smaller actions around Java, including the smaller but also significant Battle of Sunda Strait.
