[180] The account of the Easy Company ambush is derived from: 1stMar _URpt_ (_S-3_) 9; 2/1 _SAR_, 6–7; Col A. Sutter Comments 2 Feb 56; TSgt H. T. Jones ltr, n. d. The Marines scrambled out of the trucks and returned the fire. But it was necessary to attack in order to dislodge the enemy, and during the advance Easy Company took a total of 46 casualties--8 KIA and 38 WIA--in addition to six wounded truck drivers. Five of the seven officers were wounded, including the company commander, Captain Charles D. Frederick. It was estimated that the roadblock had been defended by about 200 Red Koreans, who left 61 counted dead behind them and probably removed at least as many wounded. Fifty cases of 120mm mortar ammunition were destroyed by the Marines and 300 cases of small arms cartridges. At 1615 Sutter and the remainder of the 2/1 force arrived on the scene from Wonsan just as Able Company and its prisoners appeared from the opposite direction. Helicopters having already evacuated the Easy Company’s critical casualties, Able Company brought the lightly wounded and prisoners to Wonsan without further enemy interference. Sutters’ force proceeded to Munchon-ni as originally planned. _KMC Battalion Sent to Majon-ni_ At Majon-ni an OP manned by two squads of Lieutenant Ronald A. Mason’s 2d Platoon of How Company was threatened with encirclement on the 8th when a Red Korean force gradually built up to an estimated 250 men worked around to the rear. The other two platoons of the company, reinforced with heavy machine guns and an Item Company platoon, were sent out from the perimeter. Artillery and mortars helped to scatter the enemy in confusion with estimated 40 per cent losses. Marine casualties were one man killed and ten wounded.[181] [181] 3/1 _SAR 7 Oct-25 Nov 50_, 6. 1stMar ISUM, 1200 9 Nov 50; 2/11 _SAR_, 17; Capt R. A. Mason Comments, 25 Jan 56. See also Corley Comments. On 10 November, reflecting the concern of CO 1st Marines over enemy activity in the Majon-ni area, the 3d KMC Battalion arrived as reinforcements together with a convoy of supplies. CO 3/1 assigned the unit to the sector in the perimeter recently vacated by Able Company of 1/1.[182] [182] 2/1 _SAR_, 7. Ridge, _Notes_. The celebration of the 175th birthday of the U. S. Marine Corps was not neglected at Majon-ni. Somehow the cooks managed to bake a prodigious cake, with thinly spread jam serving as frosting, and all hands were rotated a few at a time to their company CPs to receive a slice.[183] [183] Geer, _The New Breed_, 215. That afternoon an OY of VMO-6 spotted an estimated 300 enemy troops about four miles west of Majon-ni. Under direction of the aerial observers, Captain Strohmenger’s howitzers broke up this concentration.[184] [184] VMO-6 _SAR_, 8; X Corps, _Guerrilla Activities X Corps Zone, Nov 50_, 1; 1stMarDiv _PIR 18_; 2/11 _SAR_, 17.
