The Boxer Rebellion was founded in the late Qing Dynasty to resist the indecision of the Qing government in Eight-Nation Alliance on the Boxer Rebellion. Ministers of various countries decided to intimidate the rulers of the Qing Dynasty into submission by force, so they mobilized more than 400 sailors moored on the Dagu warship and arrived in Beijing in two batches at the end of May and the beginning of June. On June 10, British vice admiral Seymour commanded more than 2,000 people of the multinational coalition (known as Eight-Nation Alliance in history) and went straight from Tianjin to Beijing. The situation is getting more and more tense. At that time, there were 1700 Russian troops in Lushun who came to join the Seymour task force, but they were stranded in the Tianjin Concession because they were late, and they were on standby. In mid-June, a large number of boxers are also preparing to go to Beijing. At this point, the Qing government lost control of the situation. In order to keep power, it must make a choice, either to use the Boxer Rebellion against Seymour Alliance or to unite with Seymour Alliance to suppress the Boxer Rebellion. The Boxer Rebellion won the sympathy and support of Beijing citizens, and some Beijing garrison troops also tended to the Boxer Rebellion. Coupled with the slogan of "helping the Qing dynasty to destroy the foreign countries", the Qing government felt that the Boxer Rebellion had no intention of being embarrassed and could use it. However, the Seymour Coalition forces were aggressive, and their purpose was unknown. They also ordered Xu Jingcheng, the minister of the Prime Minister's yamen, to negotiate with the embassy and asked it to turn back halfway, which was resolutely rejected, adding to the doubts of the Qing government. After the Qing government sent military ministers Resolute and Zhao Shuqiao to Zhuozhou in batches to "inspect" the Boxer Rebellion, in June of 13, they finally recognized that the Boxer Rebellion was legal and allowed them to enter the inner city of Beijing.

When Seymour commanded the allied forces to set out from Tianjin, the Boxer Rebellion demolished the railway and stopped the invading army from advancing. On 1 1 and 12, the allies only advanced more than 40 miles. /kloc-On the afternoon of 0/3, the Boxer Rebellion and Seymour Allied Forces confronted each other in Lofa and Langfang. They used backward weapons such as broadswords, spears and rifles to fight bloody battles with the invading army, showing great courage and sacrifice (see color picture insert 1 17). After dismantling the railway connecting Beijing, the Boxer Rebellion destroyed the railway and telephone poles east of Lofa, burned Yangcun Bridge, and cut off the traffic and telecommunications links between the invading army and the Tianjin Concession. On 18, Wuwei Hou Jun (Gan Jun) of Dong Fuxiang joined the battle. Seymour Coalition forces were defeated and forced to retreat to Yangcun, where they won several wooden boats and carried the wounded and the trench down the river. The rest of the troops fled along the river in the direction of Tianjin, and were chased and intercepted by the Boxer and the Qing army. On the 22nd, they seized the Xigu armory and got a breathing space. Then surrounded by the Qing army and the Boxer Rebellion. It was not until 26th that he was rescued by a reinforcement in Tianjin and fled back to the concession, killing nearly 300 people. Seymour admitted, "If the Boxers use western-style guns, the allies they lead will be wiped out."
