Meanwhile, another 7th Marines counterforce was being organized for a massed assault to retake East Berlin. At 1000, under cover of a thundering 1,600-round mortar and artillery preparation by Marine and TAFC gunners, a reinforced two-platoon unit from Companies George and How, launched the attack. The unlucky H/3/7 platoon, in the lead, got caught between well-aimed Chinese shells and the Marines’ own protective wire. In less than 15 minutes the platoon had been reduced to 20 effectives, with Company G passing through its ranks to continue the attack. By 1123 the Marines were in a violent fire fight and grenade duel in the main trenchline at East Berlin. Tank guns, meanwhile, blasted away at Chinese troops, bunkers, active weapons, and trenches. On call they placed their fire “only a few yards in front of the friendly attacking infantry and moved this fire forward as the foot troops advanced.”[490] Heavy countermortar and artillery rounds were also hitting their mark on forward, top, and reverse slopes of East Berlin to soften the Chinese defenses. A few minutes later the 3d Battalion men had formed for the assault. During the heavy hand-to-hand fighting of the next hour the Marines “literally threw some of the Chinese down the reverse slope.”[491] Gaining the crest of the hill, the Marines by force and fire dispatched the enemy intruders. At 1233 they were again in possession of East Berlin. With just 20 men left in fighting condition at the outpost, a reinforcing platoon from I/3/7 was dispatched to buttress the assault force.

North of the 7th Marines sector four F9F Panthers, led by the commanding officer of VMF-311, Lieutenant Colonel Bernard McShane, found their way through the rainy skies that had restricted aerial support efforts nearly everywhere. In a noon MPQ mission, the quartet delivered five tons of ordnance on Chinese reinforcement troops and bunkers. Promptly at 1300--a half hour after retaking the outpost--the 7th Marines effected the relief of the last Turkish elements at Berlin and occupied the twin defense positions. And by 1500 on 8 July, the 1st Marine Division assumed operational control of the entire division sector from the Army 25th Infantry Division. Relief of individual units would continue, however, through several more days. At the same time, the mission of the 11th Marines, since 5 July under a new regimental commander, Colonel Manly L. Curry, changed from general support of U.S. I Corps, reinforcing the fires of the 25th Division Artillery, to direct support of the Marine Division. The 1st Tank Battalion similarly took over its regular direct support role. Other units under temporary Army jurisdiction, such as the Kimpo Provisional Regiment and Division Reconnaissance Company, reverted to Marine control.
