Battle of Crossing the River: After the three major battles, the Kuomintang and the Communist Party held peace talks based on eight conditions, and the reactionary Kuomintang government finally refused to sign a domestic peace agreement. On April 26th, Mao Zedong, Chairman of China People's Revolutionary Military Commission, and Zhu De, Commander-in-Chief of China People's Liberation Army, issued the order to March to the whole country. The million-strong divisions of the second and third field armies of the People's Liberation Army launched a three-way battle to cross the river on the thousand-mile front from Hukou, Jiangxi Province in the west to Jiangyin, Jiangsu Province in the east, completely breaking through the Yangtze River defense line of the Kuomintang army. On April 23, Nanjing, the center of the Kuomintang's counter-revolutionary rule for 22 years, was liberated. After the conquest of Nanjing, the scattered leaves went straight to Zhejiang and liberated Hangzhou and Shanghai successively. The Second Field Army liberated Jiujiang and Nanchang successively. The whole battle of crossing the river lasted for 50 days, wiped out more than 400,000 enemies, liberated 120 cities such as Wuhan, Nanjing, Shanghai, Nanchang and Hangzhou, and achieved great victory.
