Before the Anhui Incident, the New Fourth Army clashed with the Kuomintang army

In fact, the base area of the New Fourth Army north of the Yangtze River is closely related, Li Pinxian of the Gui clan on the Anhui side supports the self-respect of the troops, and the nominal boss of the Sulu Theater, Yu Xuezhong, has been fighting in Shandong for a long time and is also the Northeast Army, so Han Deloitte is the main person in charge of the Jiangsu area. From the perspective of conflict opponents, the Gui clan is actually the biggest enemy of the New Fourth Army, and also the Kuomintang insiders who are most dissatisfied with the New Fourth Army, and Chiang Kai-shek himself said that most people in the party advocate punishing the New Fourth Army, especially the Gui and Gu Zhu clans.

In 1938 and 1939, the New Fourth Army developed greatly in Jiangsu, Anhui, Henan, Yuwan Supeng Xuefeng, Eastern Anhui Zhang Yunyi, and Southern Jiangsu Maoshan Chen YiSuyu. General Zhang Aiping saw the opportunity to take the initiative to rush to northeast Anhui, joined forces with the Longhai detachment of the South Detachment of the Eighth Route Army, took advantage of the contradiction between the Gui clan and Sheng Zijin, and finally dominated northeast Anhui a year later, expelled Sheng Zijin, and created the smallest anti-Japanese base area in northeast Anhui, which of course also caused a certain adverse impact, making Er li dissatisfied, which was also one of the causes of the defense war in Guocun.

The clashes between the Kuomintang and the Communists in the Suwan area before the Southern Anhui Incident were two battles: the first, a series of clashes between Peng Xuefeng's troops and Tang Enbo, which led to the disastrous defeat of Peng Xuefeng's troops, and had to retreat to the east of Jinpu Road, completely losing the base area west of Jinpu Road. The second is the decisive battle between the New Fourth Army's Northern Jiangsu Headquarters and Han Deloitte's Yellow Bridge, interspersed with the Half Pagoda Set Defense War, the Guocun Defense War, and the Caodian Campaign, a series of battles that completely reduced Han Deloitte's department to the third old, and the New Fourth Army dominated the anti-Japanese situation in northern Jiangsu, created the anti-Japanese base area in central Jiangsu and northern Jiangsu, and opened up the connection with the Shandong base area.

Chen Yi's role in this was crucial, promptly deploying Guan Wenwei to seize Yangzhong, and then rationally handling the Sheng Zijin incident, helping Erli transport bullets, so that he could dispatch troops to reinforce the Defense War of Bantaji, resolutely and resolutely lead the army to the north at the critical moment of life and death, embodying the style of commander-in-chief, and later collecting troops outside Taizhou during the defense of Guocun in the war, followed by Jiang Yan to win erli and Chen Taiyun's department to remain neutral, creating the best diplomatic environment for the decisive battle of Huangqiao, and this cooperation was regarded by Mao Zedong as a model of the united front. Liu Shaoqi threaded the needle in it, and contributed to it at the right time. The emergence of Su Yu with his surprisingly victorious campaign command ability is also the greatest blessing of the East China Field Army.
