The enemy approached Wolf's Teeth Mountain ... The Eighth Route Army regiment stationed there decided to move away to fight elsewhere. Squad Leader Ma Pao-yu, his deptuy Ko Chen-lin and three soldiers ... were ordered to stay on the mountain for a delaying action to cover the shift of the main force ... To mislead the enemy attackers, they lured them up to a precipice. Here they fought resolutely till they had hurled their last grenade, then leaped off the steep cliff. Their heroism exemplifeied the prowess and noble spirit of the people's army ledy by the Chinese Communist Party."
