“七·七”事变后,日寇很快占领了华北地区,为了“巩固大东亚战争华北兵站基地”,对我抗日根据地实行了惨无人道的“三光”政策。所谓“三光”,即烧光、杀光、抢光,这早己是众所周知的了。但是,关于日寇实行“三光”政策的原因,目前尚缺少深入细致的研究。日本方面曾有“三光的残暴行径是在战争中难于避免的行为”或“冈村宁次以瑞金与百团大战作为反面教师,而提出了三光作战的方案”①的观点。在此,笔者仅就日军野蛮侵略行径的历史根源及其在占领华北期间的实际困难作一粗浅的 After the “July 7 Incident”, the Japanese aggressors quickly occupied North China. In order to “consolidate the base station of the North Station of the Great East Asia War,” the inhuman “three-light” policy was adopted against the anti-Japanese base areas. The so-called “three light”, that is, burn, kill, grab light, it has long been known. However, the reason why the “Three Lights” policy is implemented by the Japanese invaders is still lack of thorough and detailed study. In Japan, there were opinions that “the brutal act of the Three Lights is an act that is difficult to avoid during a war” or that “Okamura Ninhsu made a plan of fighting against the Three Light attacks with Ruijin and Hundred Regiments as the opposite teacher.” Here, I only make a brief introduction to the historical sources of the brutal acts of aggression by the Japanese army and their actual difficulties during the occupation of North China
