1940 65438+ 10, the Japanese invaders withdrew from Daliang for the second time, and Lin Shu ordered the Shunde guerrillas to enter the city to maintain order with the Guangyou Second Team in Wu Qin. Soon, the Japanese invaders arrived calmly and strangely. After the two guerrillas fought side by side, they immediately retreated. In mid-March, Shunde guerrillas moved from Lu Weiwei to Dashi Township in the south of Henan Province to carry out anti-Japanese activities in the name of "Jie Jun social backbone team", and the team grew to more than 20 people. In the summer of the same year, the Nanshun Working Committee was abolished, and Xihai formally established the Central South, Fan, Zhong and Shun county committees to lead the local and military party organizations in the Pearl River Delta. Luo is the secretary of the Central County Party Committee, and Lin Shu, Chen Xiangnan, Yan Shangmin and Xie Liquan are elected members of the Central Committee. In order to create an anti-Japanese armed force under the absolute leadership of the * * * Production Party, the Central County Party Committee, after deliberation, decided to form an independent squadron of Guangyou No.2 Team on the basis of Shunde guerrillas and a group of party member and progressive youths transferred from Zhongshan and Panyu. On June+10, 5438, the squadron was established in Panyu, with a team of more than 50 people, with Lin Shu as the squadron leader, Huang as the branch secretary, Huang as the instructor, and Xie Liquan, a Long March cadre, in charge of military training and command. At the end of the year, he moved to the West Sea and began to build an anti-Japanese base area in the West Sea. After the victory of the West Sea, the first squadron of the Independent Regiment attacked the puppet army stronghold in Wei Yong, Panyu at night during the Spring Festival of 1942, killing more than 90 people. Successive victories have greatly enhanced the prestige of the independent first squadron. Some United front armed forces, such as He Cheng of Panyu Shawan, Yang Zhong of He Lan, Water Brother of Shunde District 5, etc., all took the initiative to move closer to the guerrillas of the * * * production party, requesting to send people to help them train personnel and improve the combat effectiveness of the team.
The development of the armed forces of the Party aroused the suspicion of the Kuomintang. After the Southern Anhui Incident, the second anti-* * climax was set off in the whole country. The second detachment is also facing a severe test. First, the commander Wu Qin was assassinated. Then, the enemy, the puppet government, and the tacit understanding joined forces to gather more than 5,000 troops in Lintou, Xihai and Guangjiao areas, preparing for a decisive battle with the * * * production party guerrillas. In this case, according to the spirit of the Central Military Commission's instruction that "under the new situation, our struggle policy is to adhere to long-term dispersed guerrilla warfare", Lin Shu decided to take the initiative to evacuate the West Sea base area and disperse his personnel to Zhongshan, Yunnan, Nanhai and Sanshui to open up new guerrillas. The higher Party committee approved this action, ordered the establishment of the headquarters of Nanfanshun guerrilla zone in He Lan, and appointed Lin Shu as the commander. Since then, under his leadership, two revolutionary base areas, Wugui Mountain in Zhongshan and Daguwei in Panyu, have been established, and the ranks have been continuously developed and expanded, clearing the way for democratic political construction in guerrilla areas in the Pearl River Delta and winning frequently. On the other hand, in March of 1944, the traitors "Eight Tigers" and "Five Wolves" were wiped out in one fell swoop in Li Jiao, a suburb of Guangzhou. In May, Xinchuang, the pseudo-district governor was captured alive; In June, the city bridge was attacked, and the nest of Li Lang chicken was attacked at night. Later, with the cooperation of the brothers, Shunde detachment returned to the division, annihilated the Wuzhou pseudo-defense brigade, captured the captain Hu Zikui (Liang Kui) alive, and divided their troops into the old village in the first district and the wheat village in the eighth district. At the same time, democratic regimes at all levels in Zhongshan, Panyu and Shunde began to be established. In the autumn of the same year, the higher-level party Committee cancelled the headquarters of the South Fanshun guerrilla zone and established the headquarters of the guerrilla column in central Guangdong. Lin Shu, still the commander, deployed the main force to advance into central Guangdong, joined forces with Xinhui, Heshan and Gaoming brothers, and pushed guerrilla warfare behind enemy lines in this area to a climax.
At the beginning of 1945, the Pearl River Column of the Guangdong People's Anti-Japanese Guerrilla was publicly announced. Lin Shu was transferred back as commander from central Guangdong. Subsequently, the troops marched into Xijiang and went north to Wuling, clearing the way for the Eighth Route Army's southward detachment. In August, Japan surrendered unconditionally, and Lin Shu was ordered to lead a team north to Yantai, Shandong. During the War of Liberation, she served as the deputy political commissar of the Guangdong-Guangxi column. Together with other leaders, she led the team south to cooperate with the field army to liberate South China.
