On 27 February 1942, Rear Admiral Karel Doorman’s ABDA striking force sailed from Surabaya to intercept a Japanese invasion convoy approaching Java. The Allied force included Dutch, British, Australian, and American warships. It faced a Japanese escort force that included the heavy cruisers *Nachi* and *Haguro*. The Allies had no effective air cover, and communications among the four national contingents had been difficult.
The ships made contact in the Java Sea and fought intermittently for about seven hours. Japanese gunfire crippled the British heavy cruiser *Exeter*, and a torpedo sank the Dutch destroyer *Kortenaer*. As *Exeter* withdrew, the Allied formation became disordered. A destroyer engagement followed: HMS *Electra* was sunk, while Japanese destroyer *Asagumo* was damaged. The surviving Allied ships turned away as daylight faded.
Doorman attempted another attack after dark. HMS *Jupiter* struck what was believed to have been a Dutch mine and sank. Japanese cruisers *Nachi* and *Haguro* then attacked with torpedoes. *Java* was hit and sank, and *De Ruyter*, Doorman’s flagship, was torpedoed and later sank. Doorman died with the ship. The first battle therefore left the Allied force badly depleted; *Houston* and *Perth* survived the main action, while other ships were sunk or dispersed.
The fighting on 1 March was a separate follow-on engagement, not a continuation of the 27 February surface battle. The damaged *Exeter*, escorted by HMS *Encounter* and USS *Pope*, was intercepted northwest of Bawean by Japanese cruisers and destroyers. *Exeter* and *Encounter* were sunk. *Pope* escaped the surface action but was later sunk by Japanese aircraft.
The battle secured the Japanese approach to Java. Sources gave Allied losses of about 2,300 killed and Japanese losses of 36 killed; those figures covered the Battle of the Java Sea, not the separate 1 March action. The main engagement demonstrated the practical difficulties of the mixed Allied command: ships had to coordinate across national procedures and communications systems while facing a more effective Japanese force. The surviving Allied ships could not prevent the invasion from proceeding.
