1938年1月,美国驻华使馆武官卡尔逊以军事观察员身份赴华北战区实地考察,129师769团1营营长孔庆德奉命护送其通过封锁线到达晋察冀根据地。短短三四天,在复杂多变的战争环境中,两人通过交流、交锋和碰撞,从而产生相互间的尊重和理解。 In January 1938, Carlson, the military attache of the U.S. Embassy to China, went to field theater in North China to serve as military observer. Kong Qingde, commander of battalion 769 regiment 129 of 129 divisions, was escorted to escort him to the base of the Jin-Cha-Ji area through the blockade line. In the short span of three or four days, in a complex and volatile war environment, the two have mutual respect and understanding through exchanges, confrontations and collisions.
