1942年至1945年春的沁源两年半围困敌人斗争中,地雷成了民兵打击鬼子的主要武器。为开展地雷战,县、区、村层层举办了爆炸训练班。在沁源县采访过程中,沁源档案馆的同志告诉我们,沁源有一位老英雄李德昌,现在就居住在太原。他是当年的民兵队长,他带领民兵用地雷战、伏击战,打得日军闻风丧胆,是远近闻名的“爆破大王”。 During the two-and-a-half-year siege of enemy struggle between 1942 and the spring of 1945, Qinyuan was the main weapon used by militia to fight the devils. In order to carry out mine warfare, counties, districts and villages organized an explosion training course. In an interview with Qinyuan County, comrades at Qinyuan Archives told us that there is an old hero in Ethnographic Li Dechang who lives in Taiyuan now. He was the captain of the militia of that year. He led the militias to use landmine warfare and ambushes to fight the Japanese troops. He was known as the “Blast King”.
