|
12/22-12/23/42 NAVAL BATTLE OF KOEPANG After an IJN SAG led by CA Kumano bombarded Koepang a week ago I decided to move Admiral Doorman's Dutch cruiser force up from Darwin to help protect Koepang. My multiple Catalina patrol groups couldnt seem to spot the IJN raiders coming or going and the Japanese attack was unmolested by US divebombers, torpedo bombers and level bombers based at Koepang. On the night of 12/22-12/23/42 the IJN SAG came calling at Koepang again: -------------------------------------------------------------------------------- Night Time Surface Combat, near Koepang at 68,116, Range 5,000 Yards Japanese Ships CA Suzuya, Shell hits 2 CA Kumano, Shell hits 5, on fire CL Kiso, Shell hits 1 CL Tenryu, Shell hits 4, heavy fires, heavy damage DD Asashio DD Yamakaze, Shell hits 1 DD Umikaze, Shell hits 2, on fire Allied Ships CL Java, Shell hits 2, heavy fires CL Sumatra, Shell hits 11, Torpedo hits 1, on fire, heavy damage CL De Ruyter, Shell hits 9, heavy fires CL Tromp, Shell hits 5, on fire DD Banckert, Shell hits 6, heavy fires DD Van Nes, Shell hits 3 DD Witte de With DD Evertsen, Shell hits 3, on fire DD Kortenaer, Shell hits 16, and is sunk DD Piet Hein, Shell hits 8, and is sunk Poor visibility due to Rain with 100% moonlight Maximum visibility in Rain and 100% moonlight: 6,000 yards Range closes to 7,000 yards...

The Dutch forces got the worst of it having only the smaller caliber guns of the CLs present. CL DeRuyter, DD Piet Hein and DD Kortenaer are all sunk.

It looks as if the damaged IJN ships are withdrawing NW towards Soerabaja...over a half dozen subs will be placed in position to intercept. CL Sumatra is a floating hulk and is tied up pierside at Koepang along with CL Java, DD Banckert and DD Evertson effecting repairs. Looks like we will need to transfer some CAs from India and SOPAC to help protect the waters off Timor.
