Part 3

Major naval surface actions occurred on 12 July as the U.S. Navy intercepted Japanese destroyers and cruisers attempting to resupply forces on Vila and Munda. The ships’ gunfire, sounding like massive thunder and looking like a lightning storm, permitting little sound sleep, was observed from Rendova. The next day, a 90mm battery, three searchlights, and a light antiaircraft detachment arrived from the 11th Defense Battalion. The 90mm battery was staged on Kokorana until the 9th Defense Battalion displaced to New Georgia, then it went into firing positions. Light antiaircraft guns were positioned on both Kokorana and Rendova. Marines from the 11th Defense Battalion assisted the 9th in manning the radars and the 11th’s sound locator supported Battery E.

At 0800, 13 July, U.S. Army infantry units landed at Laiana Beach, about 2½ miles east of Munda airfield, and continued the drive towards Munda Point. A detachment of 22 men with one 40mm gun, one twin 20mm gun, and two .50-caliber machine guns from the 9th Defense Battalion under First Lieutenant Colin J. Reeves, went to Laiana Beach on New Georgia to defend the landing site.

Captain Robert W. Blake’s platoon of light tanks now played an important part in the assault and capture of Munda Airfield. The airfield was defended by various aviation personnel, antiaircraft units, and the 229th Infantry Regiment. During the next five days, 9th Defense Battalion tanks spearheaded the advance, knocking out enemy log bunkers, pillboxes, and other strong points. On a number of occasions during the assault on the enemy’s final defense positions north of Ilanana, the tank platoon operated in the densely wooded and irregular terrain, under conditions believed highly unsuitable for tank employment. For the first time, the Japanese attacked the tanks with magnetic mines and Molotov cocktails, bottles of gasoline with lit wicks. On the morning of 15 July, the tanks broke through the enemy’s strong positions after Army infantry had repeatedly been thrown back. The XIV Corps attack on Munda was stalled by both the dogged resistance of the defenders and the rugged terrain.

The “Murderers Row” of 155mm guns continued shelling the Munda Airfield, Baanga Island, and other outlying islands throughout this phase. The primary targets were antiaircraft and field artillery positions, and ammunition dumps. Directed by both ground and air observers, this firing proved very effective. “The artillery shelling’s accuracy has become a real thing. We can never tell when we are to die,” wrote a Munda defender. On 15 July, landing craft carried Battery A to Tambusolo Island where it was assigned the mission of covering the western approach to Blanche Channel with 155s against the incursion of still dangerous Japanese ships. On the night of 17 July at Zanana, 9th Defense Battalion Marines were involved in some memorable fighting. A few days earlier, Lieutenant Wismer led a patrol which killed four members of an enemy patrol and captured a fifth, from whom they learned that a Japanese force of 150 men was in the vicinity. A rear command post of the 43d Infantry Division with approximately 125 troops, nearly all specialists commanded by a legal officer, was in the beachhead area. The Marines under Wismer deployed for ground defense and Private John Wantuck and Corporal Maier J. Rothschild manned two salvaged Army .30-caliber light machine guns covering trails leading to the perimeter of the Zanana area. Colonel Satoshi Tomonari’s _13th Infantry Regiment_ attacked with several groups during the night, forcing Lieutenant Wismer’s defenders back to their gun pits, while Wantuck and Rothschild remained forward of the lines engaging the Japanese with machine-gun fire on each assault. The Marines were attacked by a regiment that had “the determination of a suicide squad and under the command of the Regimental Commander they are determined to fight to the last man.”

The following morning, Wantuck was found dead from gunshot and sword wounds. Rothschild was wounded in a hand-to-hand encounter with an enemy officer, whom he killed. Wantuck and Rothschild killed 18, wounded 12 to 15 others, and put a 90mm mortar crew out of action. The senior Army officer present, Major Charles C. Cox, credited these two Marines and timely artillery fire with saving the division rear and beachhead area. Rothschild and Wantuck each received a Navy Cross for their action. In all, Wismer’s detachment had repulsed four different columns, killing 18, wounding others, and capturing a prisoner. Over 100 Japanese bodies were found later on the field by Army units.

Pharmacist’s Mate First Class Francis G. Peters was with the Zanana detachment. While with the unit, he performed as a one-man clearing station for evacuating the wounded, mainly Army personnel, who were taken from the beach by boat. He remembered the attack of 17 July because the Japanese “penetrated as close as 25 yards and I could see them shooting at our men on the AA guns.” After the attack, his work really began, tending to the wounded, including a couple of Japanese soldiers.

While the fighting for New Georgia was ongoing, there were several changes in the command structure of the campaign. Major General Oscar W. Griswold relieved General Hester as commander of XIV Corps, and Rear Admiral Theodore S. Wilkinson relieved Admiral Turner as commander of Task Force 31. The buildup of forces on New Georgia continued with the arrival of elements of Major General J. Lawton Collins’ 25th Infantry Division on 21 July and the arrival the next day of the remainder of the 37th Infantry Division. What one division failed to accomplish would now be attempted by two, the 43d and the 37th.

After their initial daytime air losses, the Japanese relied on air attacks at night with only infrequent daylight bombings. One was mounted against the Rendova area on 20 July by 6 planes, one on 1 August by another 6 planes, and another on 7 August by a formation of 15 aircraft. Nightly harassing raids were made over the area by different planes and pilots all dubbed “Washing Machine Charlie.” Several larger flights were turned back by 90mm fire. Marines of Battery F, the searchlight battery, remained at their posts despite Japanese strafing, and radar men at their exposed, above ground posts remained at their stations throughout the raids, also. At dawn, after one all-night raid, a Battery C Marine was at the fuze pot stark naked, “he hadn’t had time to dress.” A total of 26 enemy planes were downed by battalion antiaircraft fire over Rendova.

On 26 July 1943, the 9th’s tanks, reinforced by six others from the 10th Defense Battalion, led the assault on enemy positions near Lambetti Plantation. Tank operations were conducted over difficult terrain consisting of steep slopes, heavy underbrush, and closely spaced trees. The Japanese were in a strongly fortified defensive position, which consisted of a number of heavy bunkers and pillboxes in a clearing. In this action, which lasted approximately five hours, one of the tanks was disabled by a magnetic mine, and two men were killed and four wounded. A second assault on this position on 28 July by a battalion of infantry and four Marine tanks, was successful. Approximately 40 heavily fortified bunkers and pillboxes were destroyed and a large number of Japanese killed or wounded by tank fire.

On 1 August, a Japanese air raid hit the torpedo boat mooring basin at Rendova. Nearby on Tombusolo was Edwin Jakubowski with 9th Defense Battalion Special Weapons, firing at the attacking aircraft. “A PT Boat was strafed and blew up next to my little island. Plywood flying all over me and one of its torpedoes went by,” he recalled. Captain Theron A. Smith, commanding Battery F, had just inspected his Number 3 Searchlight Section when the attack occurred and later wrote “some Sunday, alerts and [Condition] Reds all last night and most of the day. Attacked by two dive bombers and Zeros (estimated 50) about 1600. Two PTs destroyed, another sunk and beyond salvage.” In a footnote to the campaign, Lieutenant (jg) John F. Kennedy’s PT 109 was rammed and sunk early the next morning while operating from the Rendova base.

Field artillery firing missions against the New Georgia area continued to be conducted by Battery B until 3 August. The tank platoon of the 10th Defense Battalion, reinforced by five tanks from the 11th Defense Battalion and the surviving tank of the 9th Defense Battalion, led the assault on Kokengolo and Biblio Hills on 4 and 5 August. After two days of heavy fighting, they routed the defending forces. The Marine tanks then cleared the way to the principal objective of the entire New Georgia campaign, the Munda airfield, which was captured and occupied by XIV Corps Army troops on 5 August 1943. Regiments of the 25th Infantry Division pursued the Japanese as they withdrew north from Munda Point. On the night of 6 August a naval battle was fought in Vella Gulf, where Japanese destroyers and barges bringing in supplies and reinforcements were turned back.

The battle for Munda airfield over, the Zanana Beach and Laiana Beach detachments moved on 6 August to participate in the Munda defenses. The detachments destroyed 12 enemy planes while at these locations. A day later, the 9th Defense Battalion began moving to the Munda area. The moves were so organized that there was no more than a quarter of the battalion’s weapons out of action at any one time. The battalion was transported largely by various types of landing craft, which made the displacement a slow, laborious process. Captain Well’s Battery B of the 155mm Group moved to Kindu Point on New Georgia on 8 August and was assigned the mission with its large guns of guarding the western approaches to Blanche Channel. On landing, Battery B and an Army antitank platoon cleared the area of remaining Japanese stragglers.

At Munda Airfield, immediately after the area was cleared of Japanese, construction units moved in to repair and enlarge the “emergency” field built by the enemy. By the evening of 13 August, this work had progressed sufficiently to permit four Army Curtiss P-40 Warhawks to make an unscheduled landing and to “christen” the field with a brief fly-over. This was soon followed by the arrival of Marine air units, including VMF-123 and -124. Other Marine squadrons soon arrived, including the VMF-214 “Black Sheep” of Major Gregory Boyington, who became a grudging admirer of the 9th’s antiaircraft marksmanship and a source of entertainment with his radio transmissions while flying over Munda.

Instead of attacking the main Japanese force on Kolombangara at Vila, the American force isolated the enemy by landings on nearby Vella Lavella on 15 August. Admiral Halsey did not want another slugging match like Munda. A landing force was built around the uncommitted Army 35th Regimental Combat Team, commanded by the 25th Infantry Division’s assistant commander, Brigadier General Robert B. McLure, and supported by the Marine 4th Defense Battalion. The Japanese resisted in the air and sea, but enemy ground forces were too busy withdrawing to put up a determined resistance. The 4th Defense Battalion, led by Lieutenant Colonel Harold S. Fassett, defended the beachhead against 121 attacks and downed 42 Japanese planes. The Allied occupation of these positions and pressure from Arundel and New Georgia put Vila on Kolombangara in a precarious position. In many ways, this was a prelude to the Marine Bougainville campaign as it brought I Marine Amphibious Corps and new units not involved in the fighting into the New Georgia area. American fighter cover came from the Munda and Segi Airfields.

By 15 August, the 9th Defense Battalion was set up and emplaced in new dispersed positions. Three days later, another major naval surface action occurred off Vella Lavella as the U.S. Navy combatants intercepted destroyers and barges attempting to evacuate Japanese troops. From 16 through 19 August, Japanese artillery on Baanga Island shelled Munda Airfield and Kindu Point causing several casualties and some minor damage. Friendly aircraft and artillery operated against these elusive cannon and finally silenced them. The battalion suffered no casualties from this shelling, though one gun crew’s tent was demolished by a direct hit and there were several hits on other positions. The 9th’s antiaircraft guns were now fully placed to protect the airfield. Enemy air attacks on the Munda area, carried out at night or in the early morning, continued throughout the rest of the month. Captain Ervin’s three Battery G 40mm positions seaward of the airfield were straddled by a string of Japanese bombs that managed to just miss everyone.

The landing and occupation of Arundel Island, on 27 August, further tightened the noose around Kolombangara. Army troops were supported by Captain Blake and tanks from the 9th, 10th, and 11th Defense Battalions. Major General Collins, commanding the 25th Infantry Division carrying out this assignment, commended the Marines “for the whole-hearted cooperation and assistance rendered this division” during the operations against the Japanese in the Arundel Island campaign. They performed all assigned tasks “in a splendid manner in support of the 27th Infantry, in its action....”

Captain Reichner’s Battery A moved to Piru Plantation on 29 August and two days later began shelling the Vila area of Kolombangara. The move was made by landing craft and foot. Recalled Captain William T. Box, with the artillery group’s advance party, “we hiked up from Munda using a native guide. I remember we hiked through jungle most of the way. I remember I was scared. I remember I was glad to see that open area with the supply parachutes” left by the Army. Soon afterwards, Battery B moved to Piru and on 2 September participated in the shelling of Vila. A Japanese defender there with the _8th Combined Special Naval Landing Force_ wrote in his diary, with “the situation as it is, one just can’t help but distrust the operational plans of the Imperial Headquarters.”

The artillery group used the services of spotter aircraft, but because of enemy gunfire, switched from the light observation planes to Grumman TBFs because their armor plating gave the pilots greater protection. First Lieutenant Donald V. Sandager and Sergeant Herschel J. Cooper flew these missions over Kolombangara. “We both volunteered to a request from Major Hiatt. When we reported to Munda Airfield we had no parachutes and were told each flier had to have his own,” recalled Sandager. “The pilots were inexperienced and flew up from Guadalcanal each morning and we had to direct them to find the battery and Kolombangara. Radio communication with the battery was bad.” Admiral Halsey noted the artillery group and Lieutenant Colonel O’Neil’s ability to “utilize air spotting and the accuracy of their fire which stood out above other more experienced groups.”

The peak of enemy air activity over Munda Airfield occurred the night of 14-15 September when enemy planes kept gun crews at battle stations all night. The 90mm group expended 3,378 rounds, downing one plane and causing most of the enemy planes to jettison their bombs over the jungle or the sea. At Vila, a Japanese commander reported, “it had become very difficult to fire the antiaircraft guns as the enemy places their artillery upon our position immediately after we commence firing upon the aircraft.” At Piru, Japanese counterbattery fire hit the artillery group throughout September and the first two days of October. A number of the enemy artillery projectiles failed to detonate and there were no casualties from the shelling.

On 15 September, General Sasaki was ordered to evacuate his remaining 12,400 men from Kolombangara. The next month on 3 October, while flying his assigned air spotter missions, Lieutenant Sandager reported Vila evacuated; the Japanese had pulled out. Lieutenant Colonel Scheyer was pleased to state that for the “first time in this war the enemy had been driven from his base by bombing and artillery fire.” He concluded that at Kiska it was bombing and ship’s gunfire, at Kolombangara it was naval gunfire, bombing, and artillery fire that turned the tide. The final action of the campaign was a sea battle on 6-7 October when U.S. Navy destroyers intercepted Japanese evacuation ships during the Battle of Vella Lavella.

The Japanese air effort slackened considerably in October, and came to an abrupt halt in November 1943. While at Munda Airfield, the 9th Defense Battalion accounted for eight more enemy planes. Numerous alerts, conditions red, and general quarters stand-tos that began an hour before dawn and an hour after sunset, had occurred daily for all gun crews. In early November, Battery A moved to Nusalavata Island and Battery B to Roviana Island where the 155mm guns covered Munda Bar and the eastern approach to Blanche Channel respectively. Lieutenant Colonel Scheyer remained in command of the 9th until 3 November, when he was assigned to I Marine Amphibious Corps and the command was turned over to Lieutenant Colonel Archie E. O’Neil.
