Battle of Vella Gulf

(6–7 August 1943)

Hello there,Maybe you have seen it in the corner of your eye, when visiting the World of Warships forum.Tuccy (Associate Publishing Producer for World of Warships on the EU server) has posted for some time now dates of events that happened in history.    

Its "Tuccy"

would you like to see more of this "Tuccy", you can find him here or here

And because I like to “borrow” good ideas, and give them some attention; we go deeper in the event and see what we will find.

I hope you will enjoy and maybe even learn from it, if only to notice a friendly person like Tuccy on the WG forum



The Battle of Vella Gulf  was a naval battle of the Pacific campaign of World War II fought on the night of 6–7 August 1943 in Vella Gulf between Vella Lavella Island and Kolombangara Island in the Solomon Islands of the Southwest Pacific.
This engagement was the first time that American destroyers were allowed to operate independently of the American cruiser force during the Pacific campaign. In the battle, six American destroyers engaged four Japanese destroyers attempting to reinforce Japanese troops on Kolombangara. The American warships closed the Japanese force undetected with the aid of radar and fired torpedoes, sinking three Japanese destroyers with no damage to American ships.


After their victory in the Battle of Kolombangara on 13 July, the Japanese had established a powerful garrison of 12,400 around Vila on the southern tip of Kolombangara island in an attempt to block further island hopping by the American forces, which had taken Guadalcanal the previous year as part of Operation Cartwheel. Vila was the principal port on Kolombangara, and it was supplied at night using fast destroyer transport runs the Americans called the "Tokyo Express". Three supply runs on 19 July, 29 July, and 1 August were successfully completed.
During the final run on 1 August, a force of 15 US PT boats launched an unsuccessful attack, firing between 26 and 30 torpedoes. Four Japanese destroyers responded, and in the ensuing battle PT-109, captained by Lieutenant John F. Kennedy, later President of the United States, was sunk.By 5 August, the Americans were driving towards the Japanese held airfield at Munda on New Georgia Island just south of Kolombangara and the Japanese decided to send a fourth transport run to Vila with reinforcements.

On the night of 6 August, the Imperial Japanese Navy sent a force of four destroyers under Captain Kaju Sugiura—HagikazeArashiKawakaze of Sugiara's own Destroyer Division 4 and Shigure of Captain Tameichi Hara's Destroyer Division 27—carrying about 950 soldiers and their supplies.The Japanese airfield at Mundaon New Georgia, which the force at Vila was assigned to reinforce, was on the verge of being captured; it would actually fall later that day. The Imperial Japanese commanders expected that Vila would become the center of their next line of defense. The Japanese operational plan specified the same approach route through Vella Gulf as the three previous successful transport runs over the objections of Hara, who argued that repeating prior operations was courting disaster.

New Georgia Islands. The Vella Gulf lies between Vella Lavella and Kolombangara on the western side of the chain.
The U.S. Navy Task Group 31.2 (TG 31.2) of six destroyers—USS DunlapCravenMauryLangSterett, and Stack—commanded by Commander Frederick Moosbrugger, having been forewarned of the Japanese operation, was lying in wait, and it made radar contact with the Japanese force at 23:33. Moosbrugger's battle plan divided his forces into two divisions. Moosbrugger's own Destroyer Division 12 (DunlapCraven and Maury), whose ships retained their full pre-war torpedo batteries, was to launch a surprise torpedo attack out of the shadow of Kolambangara Island. Meanwhile, Commander Roger Simpson's Destroyer Division 15 (LangSterett and Stack), whose ships had exchanged some of their torpedo tubes for extra 40 mm guns, was to cover Moosburger's division from an overwatch position, turning to cross the enemy's course. The idea was that any attempt by the Japanese to turn into the first division's torpedo attack would expose their broadsides to torpedo attack from the second division.
The two divisions could then switch roles if a repeat torpedo attack proved necessary, or alternate roles if barges were encountered, which could be dealt with by the second division's extra guns if necessary. Having learned the harsh lessons of naval combat at night after the Battle of Kolombangara, the Battle of Kula Gulf, and a previous PT boat skirmish, and having finally addressed the technical problems that had plagued their Mark 15 torpedoes since the beginning of the war, the American destroyers did not give away their position with gunfire until their torpedoes started striking their targets.
DunlapCraven and Maury fired a total of 24 torpedoes in the space of 63 seconds before turning to starboard and withdrawing at high speed, using the mountainous island to their east to help camouflage their movements. The Americans were operating on the assumption that the Japanese had nothing to match their new centrimetric SG radar; they knew that their older meter band radars could not differentiate between the surface ships and the island and presumed Japanese radars were no better. In the event, none of the Japanese ships present actually had radar and the looming mass of the island served to conceal the American ships from visual observation. LangSterett and Stack turned to port to cross their opponent's T and opened fire as soon as the torpedoes started detonating. All four Japanese destroyers were hit by American torpedoes. HagikazeArashi, and Kawakaze burst into flames and either sank immediately or were quickly sunk by naval gunfire. The torpedo that hit Shigure was a dud that passed through her rudder without detonating, allowing her to escape into the darkness. Shigure fired eight torpedoes as Hara retreated from the scene, all of which missed their targets
