While Company E of Gayle's battalion followed the trail toward the plantation, Company G kept pace, crossing the western shoulder of Little Mount Worri. Five Army Air Forces P-39s from Airfield No. 2 at Cape Gloucester arrived overhead to support Gayle's attack, but the pilots could not locate the troops below and instead bombed Cape Hoskins, where there was no danger of hitting the Marines. Even without the aerial attack, the 2d Battalion, 5th Marines, overran the plantation by dusk and dug in for the night; the unit counted the bodies of 35 Japanese killed during the day's fighting.
On D-Day, Combat Team A lost 13 killed and 71 wounded, with artillery batteries rather than rifle companies suffering the greater number of casualties. The 2d Battalion, 11th Marines, set up its 75mm pack howitzers on the open beach, exposed to fire from the 90mm mortars upon which Petras had ineffectually showered his hand grenades. Some of the corpsmen at Red Beach, who went to the assistance of wounded artillerymen, became casualties themselves. Nine of the Marines killed on 6 March were members of the artillery unit, along with 29 of the wounded. Nevertheless, the gunners succeeded in registering their fires in the afternoon and harassing the enemy throughout the night.
At Volupai, as on Cape Gloucester, sand, mud, and land mines—sometimes carried by Japanese soldiers who detonated them against the sides of the vehicle—could immobilize even the Sherman M4 medium tank.

While the Marines prepared to renew the attack on the second day, Terunuma deployed his troops to oppose them and keep open the line of retreat of the Matsuda Force. In doing so, the Japanese commander fell back from his prepared positions on the fringes of Volupai Plantation—including the mortar pits that had raised such havoc with the 2d Battalion, 11th Marines—and dug in on the northwest slopes of Mount Schleuther, overlooking the trail leading from the plantation to Bitokara village on the coast. As soon as he realized what the enemy had in mind, Gayle sent Company F uphill to thwart the Japanese plan, while Company E remained on the trail and built up a base of fire. On the right flank of the maneuver element, Company F, the weapons platoon burst from the undergrowth and surprised Japanese machine gunners setting up their weapon, killing them and turning the gun against the enemy. The advance of Company F caught the Japanese in mid-deployment and drove them back after killing some 40 of them. Gayle's battalion established a nighttime perimeter that extended from Mount Schleuther to the trail and embraced a portion of both.
The action on 7 March represented a departure from plan. Smith had intended that both Barba and Gayle attack, with the 3d Battalion, 5th Marines, commanded since 12 January by Lieutenant Colonel Harold O. Deakin, assuming responsibility for the defense of the beachhead. The landing craft that had carried the assault troops departed from Red Beach during D-Day, some of them carrying the seriously wounded, in order to pick up the 3d Battalion at Iboki Point and bring it to Volupai. The day was waning by the time enough landing craft were on hand for Deakin's battalion. For the reinforcements to arrive in time for an attack on the morning of 7 March would require a dangerous nighttime approach to Volupai, through uncharted waters studded with sharp outcroppings of coral that could lay open the hull of a landing craft. Rupertus decided that the risks of such a move outweighed the advantages and canceled it at the last moment. No boat started the return voyage to Red Beach until after dawn on 7 March, delaying the arrival of Deakin's battalion until late afternoon. On that day, therefore, Barba's 1st Battalion had only enough time to send Company C a short distance inland on a trail that passed to the right of Little Mount Worri, en route to the village of Liappo. When the trail petered out among the trees and vines, the Marines hacked their way forward until they ran out of daylight short of their objective.
On 8 March, the 1st Battalion, 5th Marines, resumed the advance, Companies A and B moving on parallel paths leading east of Little Mount Worri. Members of Company A, peering through dense undergrowth, saw a figure in a Japanese uniform and opened fire. The person was not a Japanese, however, but a native wearing clothing discarded by the enemy and serving as a guide for Company B. The first shots triggered an exchange of fire that wounded the guide, killed one Marine, and wounded a number of others. Afterward, the advance resumed, but once again the formidable terrain—muddy ravines choked with brush and vines—slowed the Marines, and the sun set with the battalion still on the trail.
Meanwhile, Gayle's 2d Battalion probed deeper into Terunuma's defenses. Patrols ranged ahead on the morning of 8 March and found the Japanese dug in at Bitokara Mission, but the enemy fell back before the Marines could storm the position. Gayle's troops occupied Bitokara and pushed as far as Talasea, taking over the abandoned airstrip. Other patrols from this battalion started up the steep slopes of Mount Schleuther and collided with Terunuma's main strength. Fire from small arms, a 90mm mortar, and a 75mm field gun killed or wounded 18 Marines. Rather than press his attack in the gathering darkness, Gayle pulled back from the mountain and dug in at Bitokara Mission so artillery and mortars could hammer the defenses throughout the night, but he left one company to defend the Talasea airstrip.
