Yanks of the 7 th Infantry Regiment threw back a two battalion attack on their front line positions last night after a violent 5 - hour hand - to - hand battle on the crest of “Boomerang,” a strategic ridgeline south of Communist-held “Papa-san.” About 1500 Chinese rushed the position just before midnight coupled with an intense barrage of 17,500 rounds of artillery and mortar. The Reds snatched a 50-yard section of the ridgeline in the early stages of the attack, but heavy American artillery and tank fire from units supporting the 7 th Regiment foot soldiers stopped the Communist cold while Allied reinforcements were brought in.
The Reds were hurled back before dawn today, and by 5am.the sector was quiet. A grim toll of Communist casualties was counted later.
