On May 18, 1942, The 200 division broke through the blockade at Nankan and was ambushed when passing the highway between Xibao and Mogu. Dai Anlan, the division commander, was shot. On May 26, Dai Anlan died of serious injury, less than 100 kilometers away from the border.
Mao Zedong wrote an elegy for Dai Anlan: "The foreign aggression needs to be defended, and the general endows us with the task of picking up wild flowers. The teacher is called mechanized, and we can seize the best power of the tiger. We can defend the enemy in the blood, and drive the Japanese back home. We were killed on the battlefield, and our ambition was also true."
