由于革命形势的需要,1939年1月17日,李先念率新四军独立大队南下,到达随南地区,并按照党的六届六中全会的精神和中原局的指示,准备在随南一带开展敌后游击战争,创建抗日根据地。1941年4月5日,新四军第五师全体将领于洛阳店九口堰通电就职。此后的三年时间里,新四军第五师以白兆山九口堰为指挥中枢和后方基地,胜利地开展了敌后抗日游击战争和反击国民党围剿的斗争。 Due to the needs of the revolutionary situation, on January 17, 1939, Li Xiannian led the New Fourth Army Independence Brigade southward to reach the southern region. In accordance with the spirit of the 6th Plenum of the 6th Central Committee of the Party and Central Plains Bureau, Li Xiannian planned to launch an enemy rear guerrilla war War, to create anti-Japanese base area. On April 5, 1941, the generals of the Fifth Division of the New Fourth Army took office in Lukoudian, Kowloon Bay. In the following three years, the Fifth Division of the New Fourth Army successfully carried out the anti-Japanese guerrilla warfare behind the enemy’s backs and the fight against the Kuomintang’s encircling campaigns with the help of Baishazhao nine weirs as the command center and rear base.
