Not until the early hours of 30 November did the Communists resort to probing attacks by small groups armed with grenades. The headquarters and service troops gave a good account of themselves in the fire fight. Signalmen, clerks, cooks, truck drivers, military policemen--the Marines of Hell Fire Valley included a good many veterans of World War II, and they proved as steady as the tough combat-trained Commandos. Once again the value of the Marine Corps insistence on good basic training showed itself. Major McLaughlin sent reconnaissance parties south in an unsuccessful attempt to link up with the other perimeters. He decided, therefore, to remain in his positions and fight off the Chinese until air could come on station at dawn. The wounded were placed in the deepest of the three ditches and Army medics gave first aid. As the night wore on, McLaughlin’s situation became increasingly grave. By 0200 his men were out of grenades. An Army crew performed valiantly with the 75mm recoilless, firing at enemy mortar flashes until all the soldiers were killed or wounded and the gun put out of action. Twice McLaughlin’s men drove the Chinese from their mortars only to have them return. Some of the Commandos managed to slip out of the perimeter in an effort to reach Koto-ri and summon assistance. But an attempt by Noel and two men to run the gantlet in a jeep between 0200 and 0300 ended in their capture before they proceeded a hundred yards. At about 0430 the Chinese sent their prisoners to the perimeter with a surrender demand. McLaughlin, accompanied by a Commando, went out to parley through an interpreter in the hope of stalling until help arrived, or at least until some of the men escaped. “Initially I demanded a CCF surrender!” he recalls. “But it made little impression.” The Marine officer stalled until the Chinese threatened to overrun the perimeter with an all-out attack. They gave him ten minutes to discuss the capitulation with his officers. McLaughlin went from one to another of the approximately 40 able bodied men he had left. Some had no rifle ammunition at all and none had more than eight rounds. For the sake of his wounded, he consented to surrender on condition that the serious cases be evacuated. The Chinese agreed and the fight in Hell Fire Valley ended. McLaughlin succeeded in killing enough time so that more men were given the opportunity to slip away while the enemy relaxed his vigilance during the prolonged negotiations. Largest of these groups was composed of the survivors of the three small perimeters. Capraro and Buck, both of whom were slightly wounded, managed to unite with the Army infantrymen just north of them and nine Commandos, who joined them at about 0200. An hour and a half later they linked up with the Marines under Seeley, who led the combined group in a withdrawal to the high ground across the river. Outdistancing their CCF pursuers, after shooting down several, they made it safely to Koto-ri.
