The heavy fighting raged throughout the afternoon. Lieutenant Colonel Alderman, his operations officer, Major Matthew P. Caulfield, and representatives of the Fire Support Coordination Center (FSCC) flew from Khe Sanh to Hill 881S by helicopter so they could personally oversee the battle. During the action, Company I drew heavy support from the recoilless rifles, mortars, and 105mm howitzers on Hill 881S, as well as the batteries at Khe Sanh. In addition, Marine jets armed with 500-pound bombs streaked in and literally blew the top off of the easternmost enemy hill, while other fighter/bombers completely smothered one NVA counterattack with napalm. A CH-46 helicopter from Marine Aircraft Group 36 was shot down while attempting to evacuate casualties but another Sea Knight swooped in and picked up the pilot and copilot. The crew chief had jumped from the blazing chopper while it was still airborne and broke his leg; he was rescued by Lieutenant Fromme's men. This, however, was the only highlight for the North Vietnamese because Company I had cracked the center of their defense and, under the savage air and artillery bombardment, the rest of the line was beginning to crumble.(46) Lieutenant Colonel Alderman realized that his men were gaining the advantage and requested reinforcements with which to exploit the situation. Colonel Lownds, however, denied the request and directed the 3/26 commander to pull Company I back to Hill 881S immediately. The order was passed on to Captain Dabney and it hit him like a thunderbolt. His men had been fighting hard all day and he hated to tell them to call it off at that point. Nonetheless, he rapidly disengaged, collected his casualties, and withdrew. The struggle had cost the enemy dearly: 103 North Vietnamese were killed while friendly losses were 7 killed, including two platoon commanders, and 35 wounded. As the weary Marines trudged back to Hill 881S, they were understandably disappointed at not being able to continue the attack. It wasn't until later that they learned why they had been halted just when victory was in sight.[19](47)
