1898年9月18日,谭嗣同深夜密访在北京的袁世凯,要求袁杀荣禄、从天津提兵围颐和园。但是,慈禧19日回到紫禁城,21日就重新训政了。天津距北京一百多公里,假如袁世凯依谭嗣同的想法行事,当夜返津,19日杀荣禄起兵,倾其所部7000人马,首先要打败驻扎在天津的3万清军,再杀进北京,打败驻扎在北京的6万清军,其中包括聂士成统率的武毅军和董福祥的甘军。 On September 18, 1898, Tan Sitong interviewed Yuan Shikai, who was in Beijing late on night, and demanded that Yuan Shaolonglu and Tianbao be permitted to raise their troops from Tianjin to the Summer Palace. However, Empress returned to the Forbidden City on the 19th and reopened it on the 21st. Tianjin is more than 100 kilometers away from Beijing. If Yuan Shikai was to act according to Tan Sitong’s idea and return to Tianjin that night, he would kill Rong Lu on the 19th and pour over 7,000 troops in his place. First, he would defeat 30,000 troops stationed in Tianjin and then killed in Beijing. Defeating 60,000 Qing troops stationed in Beijing, including Wu Yijun at Nie Shih’s rate and Gan Jun at Dong Fuxiang.
