Two squads were then sent out to reinforce the position. They were stopped, however, by heavy Chinese artillery barrages. At the outpost, Marine artillery fires had forced the Chinese to retreat, but at 0015 the enemy reappeared at the trenchline. The artillery regiment once again applied the overhead fire remedy, but with less success--the Chinese, neither retreating nor advancing, took cover in the trenches. During the long night, attempts to reestablish communications with Detroit had proved fruitless, although battalion radio operators reported that they had heard Chinese language coming over one of the Marine radio nets used by the COP. A six-man reconnaissance detail was sent forward to investigate. It returned at 0355 with the information that Detroit was now held by the enemy. Two wounded Marines had escaped; the rest of the Detroit garrison had fallen to the enemy. At 0630 the Marines withdrew after heavy fighting that had lasted more than 10 hours. During the earlier part of the night, while the battle for outpost control raged at Detroit, reinforcements had also been dispatched to Frisco to help stabilize the situation at this adjacent Company H/3/7 outpost. Like Detroit, it had been attacked by a Chinese company, beginning about 2000. An hour and a half later some of the enemy had made their way into the trenchline, but were repulsed with the help of friendly artillery VT. Shortly after midnight the enemy again probed Frisco and reached the trenchline. At 0115, two squads jumped off from JAMESTOWN, but a rain of Chinese artillery interrupted their progress. Throughout the early morning hours of 7 October, Company H and I units were sent out from the MLR to buttress the Frisco defense and stem the enemy attack. At 0510, a reinforced platoon from the reserve company was sent to renew the counterattack. It was this Company I unit that finally restored control of the COP to the Marines.[230] Another reinforcing platoon arrived at the outpost just as the Marines there had evicted the remaining Chinese assault forces. At 0715, 7 October, Frisco was declared secure. [230] During the predawn attempt to retake Frisco on 7 October, Staff Sergeant Lewis G. Watkins, I/3/7, although already wounded, led his rifle platoon in the assault against Frisco. When an enemy machine gun impeded their progress, Staff Sergeant Watkins grabbed a wounded man’s automatic rifle to help get the assault moving forward again. At that instant, an enemy grenade landed in the midst of the Marines. Staff Sergeant Watkins immediately seized it. Just as he was about to hurl it away it exploded in his hand. The grenade took the sergeant’s life but he had saved his fellow Marines. For his bravery Staff Sergeant Watkins was posthumously awarded the Medal of Honor.
