1941年冬,日军调动了5万人马对沂蒙山抗日根据地实行“铁壁合围”,进行空前残酷的大“扫荡”。这是抗日战争时期日军在山东我根据地发动的规模最大的一次“扫荡”。在艰难困苦的50天反“扫荡”斗争中,留田突围是最惊险的一幕。当时,八路军115师的战斗部队只有一个特务营,敌我兵力对比为300:1,但我军最终不费一枪一弹、不伤一兵一卒,从敌人眼皮底下成功突围,创造了战争史上的奇迹。 In the winter of 1941, the Japanese mobilized 50,000 troops to “encircle the sieges” against the Yimengshan anti-Japanese base area and conduct an unprecedented cruel “mopping-up.” This is the largest “raid” launched by the Japanese troops in the base area of ​​Shandong during the Anti-Japanese War. In the difficult and 50-day struggle against “mopping-up”, leaving the field breakout is the most breathtaking scene. At that time, the 115th Eighth Route Army combat unit had only one secret service battalion, compared with a force of 300: 1 on the enemy’s and the armed forces. However, our army eventually managed to break through the enemy’s eyes and did no harm to one soldier and succeeded in creating a war history Miracle.
