99 years ago today, on October 24, 1926 (September 18, 1926, the first armed workers 'uprising in Shanghai failed. The British Navy entered Shanghai. This was the Shanghai workers picket who participated in the uprising. The first armed workers uprising in Shanghai failed on October 24, 1926. On October 23, 1926, in cooperation with the Northern Expedition, Shanghai workers held their first armed uprising. In August, the Central Military Commission of the Communist Party of China instructed the Shanghai District Committee of the Communist Party of China to establish a military commission. In early September, the Shanghai District Committee decided to carry out preparations for the armed uprising and decided to organize a picket of 2000 workers. On October 11, the Central Committee of the Communist Party of China approved the decision of the Shanghai District Committee to prepare for the uprising. The riot plan is formulated by the central government, and the Shanghai District Committee is responsible for investigating enemy situations and training workers to arm themselves. In mid-October, Sun Chuanfang failed one after another in Jiangxi. Sun's subordinate, Zhejiang Governor Xia Chao, had a secret agreement with Niu Yongjian, the representative of the Guangzhou National Government in Shanghai, and decided to defect, oppose Sun Chuanfang, join the National Government, and immediately marched into Shanghai. Shanghai has only more than 1000 troops stationed and 2000 police officers. The Jiangsu and Zhejiang District Committees of the Communist Party of China cooperated with Niu Yongjian. In order to cooperate with Xia Chao's attack on Shanghai, they decided to lead the Shanghai workers 'armed uprising, with Luo Yinong and Zhao Shiyan serving as the chief commanders of the uprising. The two sides agreed to start operations before dawn on October 24. On October 17, Xia Chao led his troops to Jiaxing, but was attacked by Sun Chuanfang's troops who marched from north to south to Hangzhou. On October 22, Xia Chao led his remnant troops to withdraw to Yuhang. On October 23, Sun Jun entered Hangzhou and sent troops to pursue Xia Chao. Xia Chao was killed on the Yuhang Highway. On the evening of October 23, still as originally planned, workers pickets in all districts entered their posts and stood by. Niu Yongjian knew that Xia Chao was defeated and killed, so he did not support the workers 'uprising. When Luo Yinong, Zhao Shiyan and others learned the news of the Xia Dynasty's failure in the middle of the night on the 23rd, due to time constraints, workers pickets in some areas did not receive notice to stop the operation and clashed with the police. The uprising stopped on the morning of the 24th. More than 10 workers leaders Tao Jingxuan and Xi Zuoyao died heroically, more than 100 people were arrested, and the first uprising failed.
