Feb 27th 1942: Battle of Java Sea. This engagement sealed the fate of the DEI and saw a multinational force(UK, US Australian and Dutch)of 5 Cruisers(3 Heavy) and 9 Destroyers take on Admiral Takagi’s Eastern Invasion Force convoy protected by 4 Cruisers(2 and 2) and 14 Destroyers. The Japanese Heavy Cruisers were armed with 10 8" guns and, therefore, more powerful. Their torpedoes were also of a better quality.
The commander of the multinational force was Dutch Admiral Doorman. He tried all afternoon to reach the troopships, but was foiled by the Japanese warships and a lack of Radar. (Onlythe HMS Exeter had it.) the Allies even had local Air Superiority as the Japanese planes were it of range. In the initial engagement gunnery was poor and only an 8" shell hit Exeter, which had to retire. The Japanese launched two torpedo attacks, but only the Dutch Destroyer, Kortenaer, was hit and sank. Only one Japanese Destroyer was forced to retire and at 6pm the Allies withdrew.
About 11pm that evening the two fleets met again and this time the Japanese torpedoes hit both Dutch Cruisers, including the Dutch Admiral’s flagship, the De Ruyter. Only 111 survived on the two ships. This time the surviving Australian Cruiser, Perth, and USS Houston retired for good.
The Japanese troopships unloaded the next day.
