Fumes from the 90mm gun choked the Marines in the vehicle as they listened to the clamor of North Koreans on the hull. The infantryman who had been pulled to safety by Cummings suddenly went berserk and had to be knocked out. Then the officer was forced to choose between two evils: either his crew must succumb to the acrid fumes or take its chances on opening the pistol port for ventilation. He opened the port. A grenade bounced inside, and the ear-shattering explosion within the steel enclosure wounded Cummings, the rifleman, and one of the tank gunners. At this moment the semi-conscious Marines resigned themselves to the worst.[268]

Help was on the way, however, and it was timed to the split second. Just as the grenade exploded, Sergeant Marion C. Altaire’s M-26 moved to the mouth of the defile and “scratched the back” of the beleaguered vehicle with bow machine-gun fire. Riddled Red soldiers were swept from the top of Cummings’ tank and piled up alongside. Within a few minutes, a VMF-214 flight appeared over the pass, and the planes peeled off to bomb, rocket, and strafe the high ground.[269]

As the tide of battle swept past, Cummings and his men opened the hatch, coughing and choking, and drank in long breaths of fresh air. It took them a moment to realize that they were back again in the land of the living after one of the closest calls that Marines have ever experienced.

Company G of 3/1 fought back on the right of the MSR and gained the high ground above the pass. Simultaneously, Staff Sergeant Arthur J. MacDonald led the second section of Cummings’ tank platoon into the defile, and the M-26s laid down heavy 90mm and machine-gun fire on the crescent of North Korean emplacements ahead. A total of six enemy AT guns was destroyed, but not before the weapons had knocked a track off Cummings’ vehicle and damaged two others to a lesser extent.[270]

The 2d Battalion drove to the top of the high ground on the left of the road, and the Marines enjoyed a small-scale “turkey shoot” as the North Koreans pulled out and pelted toward Sosa. While the assault units consolidated their holdings, the remainder of the 2d and 3d Battalions moved into the area around the defile and dug in for the night.

The 1st Marines’ attack along the highway had netted 4,800 yards. Despite repeated clashes in the course of the day, 2/1 lost only one killed and 28 wounded, and Company G of the 3d Battalion suffered six WIA. Enemy losses included 250 killed and wounded, 70 prisoners, one T-34 tank, several AT guns, and large quantities of small arms and ammunition.[271]

[271] 1st MarDiv SAR, Annex Oboe Oboe; 2/1 SAR; and 3/1 SAR. In its account of NKPA losses for 17 September, 2/1 lists four other enemy tanks destroyed. These vehicles were among the six knocked out jointly by the 1st and 5th Marines and Able Company Tanks at the dawn ambuscade near Ascom City. 1st MarDiv G-2 reports of 14 NKPA tanks destroyed this date cannot be supported by the records of subordinate units. In addition to the six T-34s destroyed in the morning and the single vehicle knocked out by our tanks near Mahang-ri, one other kill was recorded by Marine air.
