context_page_description: The Battle of Viru Harbor was a battle of the Pacific campaign of World War II that took place on New Georgia island during the New Georgia Campaign from 28 June – 1 July 1943. It was one of the first actions of the campaign and involved an overland advance by elements of a Marine Raider battalion, supported by a United States Army infantry company. Supported by airstrikes, the Marines carried out an enveloping attack on the Japanese defenders around the harbor and forced them to withdraw. The harbor was subsequently used by US forces to support further operations, although plans to build a PT boat base in the area were later canceled when the harbor was found to be unsuitable.
context_section_description: The original US plan for the capture of Viru Harbor involved B Company, 103rd Infantry Regiment (Captain Raymond Kinch) coming ashore directly inside the harbor from three destroyer-transports (Hopkins, Kilty and Crosby), while Companies O and P from the 4th Marine Raider Battalion—other elements from the battalion had been sent to secure Wickham Anchorage—advanced overland from Regi, near  Lambeti Village, to the south. The Segi beachhead would be held by the Companies A and D, 103rd Infantry Regiment. The Marines had begun moving to Regi by rubber boats from Segi Point on 27 June, having arrived at Segi Point on 21 June during the preliminary operation to protect Kennedy and his small group of local forces. The troops from B Company, 103rd Infantry Regiment were reinforced by part of D Company, 103rd Infantry Regiment and were supported by a battery of the 70th Coast Artillery Battalion and part of Company D, 20th Naval Construction Battalion. These troops formed part of  Colonel Daniel H. Hundley's Eastern Landing Force.
  The Japanese troops defending the area were commanded by First Lieutenant Takagi and amounted to 245 men from a company from Major Masao Hara's 1st Battalion, 229th Infantry Regiment (Colonel Genjiro Hirata), which had been detached from Major General Minoru Sasaki's Southeast Detachment. Hara's infantry company was reinforced by personnel from Commander Saburo Okumura's Kure 6th and the Yokosuka 7th Special Naval Landing Forces under Commander Takeda Kashin. Together these units formed part of the 8th Combined Special Naval Landing Force. Fire support included several guns including a 3-inch coast defense gun, four 80 mm guns, and eight other guns of varying types and calibers.
  The US destroyer-transports entered the harbor early on 30 June, but found that the Marines' advance had been delayed. Coming under fire from a Japanese 3-inch field gun from Tetemara Point, and having been unable to establish radio contact with Currin's Marines, the US naval commander, Commander Stanley Leith, decided to withdraw from the harbor. After waiting offshore for the agreed upon signal from the Marines while remaining out of range of the defending Japanese coastal artillery, the ships moved towards Segi Point instead, landing the company from the 103rd Infantry at Nono. Leith assessed that the Marines were potentially in trouble and needed assistance, which could be provided by Kinch's company if they advanced overland to link up with them. As the landing force departed Viru Harbor, Hara reported that his forces had repulsed the landing attempt.
  Meanwhile, the Marine raiders' approach saw them advance 12 miles (19 km) through dense terrain, and had been delayed due to several skirmishes with the Imperial Japanese Navy and Army troops that were guarding the approaches to Viru Harbor. During the advance, Currin's men clashed with Japanese troops around the Lambeti Plantation on both sides of the Lakuru River on 28 June and then again around the Choi River on 29 June. He then received intelligence that the main concentration of Japanese forces was around the western shore of the harbor, at Tetemara, with an outpost across the harbor at Tombe. 
  The Marines stopped short of the junction of the Tetemara–Tombe trails, close to their objective (Viru Harbor) on the evening of 30 June, and prepared to launch their attack the following day. Currin's men subsequently launched two-pronged attack the following morning; two platoons were detached to attack Tombe from the northeast, while the rest of the regiment skirted around the harbor to the north, crossing the Viru, Tita and Mango Rivers, and assaulted Tetemara from the southwest. The outpost at Tombe was quickly overwhelmed around 08:45 on 1 July, while the main body of Marines drove the Japanese out of Viru in a running battle that lasted until the early afternoon. They were supported by preliminary air attacks by seventeen US Navy Dauntless dive-bombers, while landing craft with combat supplies (ammunition and fuel) entered the harbor to ensure rapid resupply.
