Today, we bring you an important turning point in General Feng's life, opening a new page in his revolutionary struggle history-Wuyuan Oath Division.

In 1925, the National Army led by Feng Yuxiang was subjected to a joint attack by domestic reactionary warlords under the pretext of "fighting against the Red Army". In order to avoid the target of the attack and divert the enemy's attention, Feng Yuxiang sent a telegram to retire in January 1926. On February 20th, he traveled through Outer Mongolia to the Soviet Union for investigation. During the visit, General Feng witnessed the superiority of socialism with his own eyes and believed that "the Soviet Union is a socialist country. All facilities and systems in society are for the benefit of the common people. Therefore, it was associated with China's "waiting for revitalization" and found an example in the Soviet Union. At the same time, he realized that "the complete success of the revolution requires clear ideology and correct party leadership." Therefore, when he visited Lenin's tomb, he swore to "fight for the national revolution" and fulfilled the procedures for the entire army to join the Kuomintang as a collective.

During his several months of investigation in the Soviet Union, the revolutionary situation in the country underwent a sharp change. In July 1926, the National Revolutionary Army swore allegiance to the Northern Expedition in Guangzhou, and the magnificent Northern Expedition War began. The Northern District Committee of the Communist Party of China, based on the situation at that time, intensified the work of uniting and transforming the National Army. Yu Youren and translator Ma Wenyan were invited to Moscow to urge Feng Yuxiang to return to China to join the National Revolutionary Army and support the Northern Expedition army. Feng Yuxiang returned home on August 17 with the help and encouragement of the Soviet Union and the CPC.

After returning from the Soviet Union, Feng Yuxiang arrived in Wuyuan on September 16, 1926. The National Army and the Fengzhi Army suffered a major defeat in the Battle of Nankou, with over 100000 troops retreating from Pingdiquan in Baotou. 50000 to 60000 people were scattered in the Cha and Sui areas, suffering heavy losses. Upon hearing that Feng Yuxiang had returned, everyone was filled with joy and excitement. Feng attracted everyone together like a magnet. At the Wuyuan Conference, Zhang Zhijiang, Li Mingzhong, Lu Zhonglin, and Song Zheyuan from the First Army of the National Army were present; Deng Baoshan and Li Yunlong from the Second Army; Xu Yongchang from the Three Armies; Five military forces are mobilizing their strength; Liu Jun Gong Fukui and others elected Feng Yuxiang as the Commander in Chief of the National United Army. Feng Ji issued a declaration expressing his political views: to respect the will of Sun Yat sen, carry out the national revolution, and implement the Three Principles of the People. In response to the Northern Expedition of the National Revolutionary Army, unite in battle, and fulfill Mr.'s last wish.On September 17, the flag-giving ceremony of Wuyuan was held, which shocked China and foreign countries.。The venue is located on the earthen platform of the Xitou Square of the county government. All officers and soldiers of the National Revolutionary Army follow Feng Yuxiang's orders and attend the conference as members of the National Party. Yu Youren presented the flag as a standing executive member of the Central Executive Committee, while Feng Yuxiang publicly accepted the party flag. Liu Bojian's speech mainly elaborated on the establishment of a political work system in the military. Ulanskanov delivered a congratulatory message. Feng Yuxiang solemnly took the oath of office and read out the oath: "The purpose of our national army is to awaken the people with the ideology of the Kuomintang, eradicate traitorous warlords, overthrow imperialism, seek China's freedom and independence, unite with the world's nation that waits for us equally, and fight together. We solemnly swear to live and die together, and not to stop until we achieve our goals. This oath." The crowd was thunderous, and Feng Yuxiang raised his arms and shouted, "Comrades, you have worked hard!" He went down the mountain and called out to the sea, "Serve the revolution," with great courage soaring.

Next, a telegram was read out: Wuyuan County will be renamed Yiqi County, and a new military rule will be issued: "Do not quit smoking and drinking, quit prostitution and gambling. Eliminate arrogance and laziness, eliminate extravagance. Implement diligence and frugality, sacrifice for the party. Only with the national revolution can we succeed. After the meeting, Feng Yuxiang raised the red flag and participated in the grand parade of the oath taking team, shouting slogans such as "Strike imperialism!" and "Eliminate traitorous warlords.

After the oath of Wuyuan, Feng's troops formally broke away from the Northern Warlord system and became the National Army.

The Wuyuan Oath is a significant historical turning point for the National Army in politics and military affairs, marking a new starting point for the revolution. As Zhou Enlai said, "After taking the oath of allegiance in Wuyuan and receiving political training, the Northwest Army became the dominant force at that time.
