The Battle of Munda Point was a battle, from 25 July – 5 August 1943, between primarily United States Army and Imperial Japanese Army forces during the New Georgia Campaign in the Solomon Islands in the Pacific War. The battle took place following a landing by U.S. troops on the western coast of New Georgia from Rendova, as part of an effort to capture the Japanese airfield that had been constructed at Munda Point. This advance had become bogged down and while the Allies brought forward reinforcements and supplies, the Japanese had launched a counterattack on 17–18 July. This effort was ultimately unsuccessful and afterwards U.S. forces launched a corps-level assault to reinvigorate their effort to capture the airfield. Against this drive, Japanese defenders from three infantry regiments offered stubborn resistance, but were ultimately forced to withdraw, allowing U.S. forces to capture the airfield on 5 August. The airfield later played an important role in supporting the Allied campaign on Bougainville in late 1943.

Background

On 2 July 1943, US forces from Major General John H. Hester's 43rd Infantry Division, crossed the Blanche Channel from Rendova, which had been secured as part of the preliminary phase of the Allied operation to secure New Georgia. A few days later began a westward advance towards the Japanese-held airfield at Munda Point, which was a major objective of the Allied campaign. Over the course of two weeks, they undertook a slow advance along the coast towards the airfield. Held up by the harsh terrain and strong Japanese defenses, the advancing US troops became disorganized and the advance stalled. The inexperienced US troops, hungry and tired, began to lose their fire discipline and forward momentum.^[2] There were a high number of severe cases of combat stress reaction among US troops during this time.^[3][4]

Historian Samuel Eliot Morison described the situation:

Darkness came to the jungle like the click of a camera shutter. Then the Japanese crept close to the American lines. They attacked with bloodcurdling screams, plastered bivouacs with artillery and mortar barrages, crawled silently into American foxholes and stabbed or strangled the occupants. Often they cursed loudly in English, rattled their equipment, named the American commanding officers and dared the Americans to fight, reminding them that they were "not in the Louisiana maneuvers now." For sick and hungry soldiers who had fought all day, this unholy shivaree was terrifying. They shot at everything in sight – fox fire on rotting stumps, land crabs clattering over rocks, even comrades.^[5]

In order to restore the situation, Major General Oscar W. Griswold, commander XIV Corps, was sent to New Georgia to assess the situation. He reported back to Admiral William Halsey on Noumea that the situation was dire and requested reinforcements in the form of at least another division to break the stalemate.^[6] Griswold took over command of the troops in the field on 15 July and began preparations for a corps-level offensive.The movement of reinforcements and supplies from Guadalcanal and the Russell Islands took time, and Sasaki took advantage of the disorder on the American side,^[7] launching a counterattack on 17/18 July.^[8]

Japanese preparations for the counterattack had begun with the movement of reinforcements from the 13th Infantry Regiment from Kolombangara and Bairoko.^[9] On 14 July, six companies began their approach march, but were held up for three days by harsh terrain. On 17 July, the Japanese troops launched an attack against the US rear areas, raiding the 43rd Infantry Division's command post, kitchen areas and medical aid stations. Elements of the attacking force managed to penetrate as far as the original US beachhead around Zanana, but were repulsed by artillery and counter penetration forces. Meanwhile, the Japanese 229th Infantry Regiment attacked the high ground held by the US 103rd and 169th Infantry Regiments, where they came up against stiff defense. Eventually, the Japanese counterattack petered out on 18 July.^[10]

Battle

On 23 July, the US 43rd Infantry Division was reinforced by the 37th and 25th Infantry Divisions.^[11] The following day, the US preparations for the offensive were completed; the 37th was deployed inland with three regiments—the 145th,161st and 148th—along the front from south to north, while the 43rd Infantry Division pushed two regiments forward, the 103rd and 172nd Infantry Regiments, and held the 169th back in reserve. Meanwhile, the Japanese commander, Major General Minoru Sasaki, disposed three battalions of Colonel Genjiro Hirata's 229th Infantry Regiment, reinforced by a single company from the 230th Infantry Regiment. The 13th Infantry Regiment would be committed against the US right flank. Japanese indirect fire support consisted of a number of units, including antiaircraft and antitank units.^[10][12] US forces committed to the effort to capture Munda totaled around 30,000, with seven infantry regiments ultimately being committed from three different divisions, while Japanese forces committed around 8,000 troops.^[1][13]

The attack began on 25 July, supported by naval gunfire and artillery support. Artillery support included 105 mm and 155 mm guns, while the destroyers fired their 6-inch deck guns. Allied aircraft also carried out airstrikes along the coast. While visually spectacular, and involving thousands of rounds, the preparatory fires did not initially result in a breakthrough for US forces. The defending Japanese troops were able to reoccupy their pillboxes after the barrage. The US Marine tanks that were supporting the infantry found the ground too steep and eventually the US attack stalled with no gains being made by the 37th Infantry Division while the 43rd gained a small amount of ground. The Japanese had constructed many pillboxes in the area and on 26 July, the US 103rd Infantry Regiment came up against 74 of these structures in a narrow front. Again, the US troops utilized indirect fire to reduce these, while infantry armed with flamethrowers, and operating closely alongside Marine tanks.^[14][15]

Inland, the US troops attacking on the right advanced steadily towards Bilbao Hill, making steady gains over several days. The advance in the north pushed too far forward, outstripping their supplies and neighboring units, and on 28 July the Japanese 13th Infantry Regiment found a gap in the US line between the 148th and 161st Infantry Regiments, and surrounded a US supply dump. In response, two battalions of the divisional reserve (169th Infantry Regiment) were committed. Four US rifles companies counterattacked the 200 Japanese troops around the supply dump, restoring the situation while incurring heavy casualties. Meanwhile, the offensive in the south continued towards Shimzu Hill, about 1,000 yards (910 m) from the outer limits of the airfield continued. On 30 July, the Japanese commander order a withdrawal closer to the airfield, as casualties had heavily reduced his fighting elements. Shimzu Hill was taken by US forces the following day.^[16][17]

As the fighting continued, the Japanese medical and resupply systems broke down as the Sasaki's men were reduced to around half strength. On 1 August, elements from the 103rd Infantry Regiment reached the outskirts of the airfield, while the 27th Infantry Regiment, detached from the 25th Infantry Division, was pushed into the line to reinvigorate the final drive. Japanese troops defending the ridges along the Munda Trail hastily withdrew when pressed and by 2 August only limited opposition was provided, except around Bibilo and Kokoengolo Hills. The advancing US divisions converged around the eastern edges of the airfield on 3 August, but the Japanese defenders continued to offer resistance around the hills. Throughout 4 August, Japanese pillboxes and foxholes were reduced by US troops attacking with indirect fire support weapons and machine guns. Fighting alongside tanks from the US Marine 9th and 10th Defense Battalions, and supported by mortars and 37 mm guns, US infantry captured the airfield late on 5 August.^[1][18][19]

Aftermath

After losing the battle for the airfield, Japanese forces abandoned New Georgia and a large number of troops redeployed to defend nearby Kolombangara,^[20] while others were sent to Bangaa Islet, which was about 4,000 yards (3,700 m) west of Munda. Initially, Sasaki believed further troops would be sent south from Rabaul to support a counterattack in New Georgia.^[21] The U.S. employed the airfield to cover landings on Vella Lavella, and in its campaign as part of Operation Cartwheel to isolate the major Japanese base at Rabaul, New Britain.^[22] Casualties during the fighting around Munda amounted to 4,994 US troops killed or wounded from 2 July until the capture of the airfield. Against this, the Japanese lost 4,683 killed, with an unknown wounded over the same period.^[1]

Meanwhile, several Naval Construction Battalions, including the 24th and 73rd, began repairing the airfield and expanding its capacity; by mid-August two US Marine fighter squadrons were operating from the airfield in support of operations on Vella Lavella. US ground forces on New Georgia were further reinforced with the arrival of the 27th and 161st Infantry Regiments from the 25th Infantry Division to assist with mopping up operations. This saw the 27th and 161st Infantry Regiments advance north towards Bairoko. The 27th cleared both Mount Tirokiambo and Mount Bao,^[23] while the 161st closed in on Bairoko, which was secured by 24/25 August. Meanwhile, the 169th and 172nd Infantry Regiments secured Baanga Islet by 21 August. Arundel Island was captured by US forces in early September.^[24]

During the Bougainville campaign, commencing in late 1943, over 100 Allied aircraft operated from Munda airfield. It was, according to author Mark Stille, the "most important airfield" used to support the Allied invasion.^[25]
