The CIC team warned that another attack on the perimeter by the 45th NKPA Regiment would take place on the night of 11–12 November. As a prelude, General Pak made an effort to terrorize inhabitants who had kept the team informed of his plans and movements. Some of the villagers took his threats seriously enough to prepare for a hurried leavetaking, but the Civil Affairs section reassured them and put a curfew into effect.[185] [185] Col T. L. Ridge interv, 22 Nov 55. After such a menacing build-up, the second attack on the perimeter fizzled out like a damp firecracker. A few probing jabs, beginning at 0130, were followed by a weak main assault on the KMC front which was easily repulsed. The enemy tried again to overrun the OP but gave up the attempt after stumbling into a field of “Bouncing Betty” mines. At 0600 the last action of the Majon-ni operation came to an end as the Communists withdrew. Friendly losses were two men killed and six wounded.[186] [186] 3/1 _SAR_ 7 _Oct-25 Nov 50_, 6. 1stMarDiv _URpt_ (_S-3_) 9. 1stMar _SAR_, 11; 2/11 _SAR_, 17. The “Bouncing Betty” type of antipersonnel mine was equipped with a spring which sent it several feet into the air to explode with maximum destructive effect. This was the final appearance of the 15th NKPA Division, which apparently abandoned Majon-ni as an objective and transferred its guerrilla operations southward along the Imjin valley. The relief of the Marines and KMCs on position began the next afternoon as elements of the 1st Battalion, 15th Infantry, U. S. 3d Infantry Division, arrived to take over the perimeter. The Army column, including 34 Marine supply vehicles, had moved out from Wonsan at 1030 the day before. Although 2/1 (less Dog Company) had maintained its blocking positions at Munchon-ni, the convoy was stopped a few miles beyond the Marine outposts by a wrecked bridge and three large craters. Guerrillas poured in small-arms fire from the high ground which resulted in two soldiers being killed and four wounded. Two Marine trucks and a jeep were destroyed. Extensive repairs to the road being needed, Lieutenant Colonel Robert M. Blanchard, the commanding officer of 1/15, formed a defensive perimeter for the night. The column reached Majon-ni without further incident at 1530 on the 13th.[187] [187] Air Off 1stMarDiv tel to G-3 1stMarDiv, 1445 12 Nov 50; S-3 1stMar tel to G-3 1stMarDiv, 1845 12 Nov 50; LnO 1stMar tel to 1stMarDiv, 1530 14 Nov 50; G-3 1stMarDiv tel to S-3 1stMar, 1600 14 Nov 50; 1stMarDiv _POR 146_; 3/1 _SAR 7 Oct-25 Nov 50_, 3–4, 6–7; 2/1 _SAR_, 9; 1stMar _SAR_, 11–12; Capt Max W.
