It was during the exchange with the Chinese that Sharon and his men spotted the second North Korean tank under a pile of brush on the right of the road. The platoon leader, accompanied by Staff Sergeant Richard B. Twohey and Corporal Joseph E. McDermott, climbed upon the dormant vehicle. Suddenly the periscope began to revolve. McDermott smashed the glass and Twohey dropped in a grenade. With Sharon they jumped to the ground just as the grenade exploded inside the machine. The tank engine roared and the vehicle lurched toward the three Marines. Twohey jumped on it again and dropped another grenade down the periscope. After the dull thump of the second explosion, the T-34 stopped dead and began smoking. By this time Staff Sergeant William L. Vick’s 75mm recoilless gun section and 3.5-inch rocket crews of Company C had moved up. Together they gave the _coup de grace_ to the damaged T-34. Simultaneously, Sharon’s men saw a thatched hut farther down the road disintegrate as tank number three emerged, its 85mm rifle swinging menacingly toward the valley crowded with Marines and vehicles. First Lieutenant Raymond J. Elledge fired his 75s from their carts, and Company C’s rocket launchers opened up. The T-34 took hits but rumbled on. Seconds earlier, First Lieutenant Dan C. Holland, Forward Air Controller for 1/7, had radioed overhead Corsairs for assistance. One of the gull-winged planes plummetted out of formation and unleashed a pair of five-inch rockets. They were direct hits. The T-34 blew up and died on the road.[276] [276] Available records do not indicate whether tank number three should be credited to VMF-312 or to VMF(N)-513, both of which had close-support flights in the area. Sharon and his men moved forward cautiously. While passing the blazing hulk, they spotted enemy tank Number Four, camouflaged against a hillside just ahead. At almost the same moment, Marines passing Chinhung-ni stumbled upon docile tank Number One in the midst of their formation. Recoilless rifles and rocket launchers blasted the machine, and its crew climbed out and surrendered. Sharon then led the antitank crews through the river bed toward the fourth T-34. The Communist tankmen, entrenched on the slope behind their empty vehicle, gave up without a fight. The tank itself was knocked out by 3.5-inch rockets and 75mm shells; and the 344th NKPA Tank Regiment ceased to exist. _The Fight for How Hill_ After the destruction of enemy armor, Colonel Litzenberg began deploying the 7th Marines in perimeter around the valley junction at Chinhung-ni. The advance had netted about 6000 yards by midafternoon, and the remaining daylight was needed to bring all elements forward and consolidate the newly won ground.[277] [277] 7thMar _SAR_, 13; and 1stMarDiv _POR 116_.
