On July 9, 1926, the National Revolutionary Army held the oath-taking ceremony of the Northern Expedition in Guangzhou. In February 1926, the Central Committee of the Communist Party of China held a special meeting in Beijing, putting forward the political proposition of sending troops to the Northern Expedition to overthrow the rule of warlords, and decided to step up the mass work in Hunan, Hubei, Henan, Hebei and other places to meet the Northern Expedition. At that time, the warlord Wu Peifu's army was about 200,000 people, concentrated in Hunan and Hubei areas; the warlord Sun Chuanfang's army was about 200,000 people, entrenched in Jiangxi, Fujian, Anhui, Zhejiang and Jiangsu At the beginning of May, the Ye Ting Independence Regiment of the Fourth Army of the National Revolutionary Army and the 15th Regiment of the Eighth Brigade of the Seventh Army advanced into Hunan from Zhaoqing, Guangdong and Guilin, Guangxi respectively, to assist Tang Shengzhi and kick off the Northern Expedition.

On June 5, the Guangzhou National Government appointed Chiang Kai-shek as the commander-in-chief of the National Revolutionary Army. On June 28, Chiang Kai-shek ordered the Tenth and Twelfth Divisions of the Fourth Army to set out from Shaoguan to assist Hunan. On July 1, Chiang Kai-shek issued a mobilization order for the troops of the Northern Dynasty. The mobilization order stated: "This army will inherit the legacy of the former Marshal, and if it wishes to implement revolutionism and ensure the interests of the nation, On July 4, the Kuomintang Central Committee adopted the Declaration on the Northern Expedition of the National Revolutionary Army. "The general cause of all the hardships of the Chinese people lies in the aggression of imperialism and the tyranny of its traitorous warlords." The task and purpose of this Northern Dynasty was to "exterminate the forces of the traitorous warlords," "realize the only needs of the Chinese people," and "build a unified government of the people." The declaration expressed the determination of the Chinese Kuomintang to "plead for the people's orders, eliminate adultery for the country, succeed or fail, and ignore any sacrifice." It called on the people of the whole country to rally together to help its revolution succeed in one fell swoop, and firmly believed that the national revolution would surely win. On July 9, Chiang Kai-shek's inauguration as commander-in-chief of the National Revolutionary Army and the oath-taking conference of the National Revolutionary Army's Northern Expedition were grandly held at the East Campus in Guangzhou. Party, government and army officials and people from all walks of life 50,000 more than one person attended the conference. Tan Yankai, acting chairperson of the National Government, gave the seal, and Wu Zhihui, a representative of the Party Department of the Central Committee of the Kuomintang, presented the flag. Chiang Kai-shek was sworn in, delivered a reply, and held a military parade. Li Jishen was the commander-in-chief, and Zhang Zhizhong was the commander-in-chief. Chiang Kai-shek issued a manifesto, a telegram, and a letter to the military and people of Guangdong. The manifesto said: "The Chiang Kai-shek is taking office now, and I would like to inform the people of three things. First, Third, we must deeply integrate our entire army with the people, and regard it as the army of the people, and then demand that the people of the whole country share the responsibility for the revolution. If our soldiers in the whole country can take the responsibility of saving the country and loving the people, and are not puppets of imperialism, the Zhongzheng must be regarded as the army of friends of the revolution. If they can surrender to righteousness, implement the Three People's Principles, and work together for the national revolution, the Zhongzheng must be regarded as a comrade of our party. There is absolutely no opinion of the north and the south cherishing the territory, let alone the old and the new. If they rely on force, are willing to risk their lives, seek to endanger our revolutionary base areas, resist the national revolutionary army in our provinces, and are happy to serve the imperialists, and do not hesitate to trap the country in a land of eternal disaster, they must regard the public enemy of the people of the whole country and swear to destroy it and clear it up. " Chiang Kai-shek, in the name of the commander-in-chief of the National Revolutionary Army, announced the official start of the Northern Expedition. On the same day, the General Command of the National Revolutionary Army was established. The commander-in-chief consists of one chief of staff, who is concurrently served by Bai Chongxi, deputy chief of the general staff of the Military Commission of the Nationalist Government; there is one general counselor, who is served by Zhang Qun, a student of Chiang Kai-shek studying in Japan: there are several senior advisers. The "Organizational Outline of the General Command of the National Revolutionary Army" formulated by Chiang Kai-shek and promulgated by the Nationalist Government stipulates that all army, sea and air forces under the Nationalist Government are under its jurisdiction; the commander-in-chief of the National Revolutionary Army is fully responsible for the Nationalist Government and the Chinese Kuomintang militarily and also serves as the All organs of the military, civil and financial departments under the Nationalist government shall be under the command of the commander-in-chief, and shall handle official business with his will; when the commander-in-chief goes out for war, a public security committee shall be established to act on behalf of the commander-in-chief. The committee shall be commanded by the political committee, and its decisions concerning military affairs shall be handed over to the general headquarters for execution. The National Revolutionary Army has a total of about 100,000 people and marched in three ways. The main way is that the fourth, seventh and eighth armies attacked Hunan and Hubei. In July they attacked Changsha; in August they defeated Wu Peifu's main force in the battles of Tingsi Bridge and He Shengqiao in Xianning, Hubei, and captured Wuchang in October. In the second way, the second, third and sixth armies attacked Jiangxi. In November they occupied Nanchang, Jiujiang and annihilated Sun Chuanfang's main On the third route, the First Army advanced towards Fujian and Zhejiang provinces. Due to the internal division of the enemy, they occupied Fujian and Zhejiang provinces in December. During the Northern Expedition, the Communist Party of China mobilized the masses to give active support and cooperation. In the spring of 1927, the workers in Hankou and Jiujiang expelled the British imperialists and took back the concession. The Shanghai workers held three armed uprisings to occupy Shanghai. The national peasant movement centered in Hunan also showed a surge. The revolutionary forces quickly spread to the Yangtze and Yellow River basins. Imperialism therefore stepped up its intervention. The United States transferred 4,000 soldiers from Manila to Shanghai. Britain, France, Japan, and Italy and Canada sent warships and troops. The imperialist army gathered in Shanghai reached 23,000 men and more than 90 warships. At the same time, new agents were found from within the revolutionary camp. The Kuomintang rightists represented by Chiang Kai-shek stepped up their collusion with imperialism and planned to mutiny and revolution. In the Communist Party of China, Chen Duxiu gave up the leadership of the proletariat, adopted a policy of compromise and concession against the counter-revolutionary actions of the Kuomintang Rightists, suppressed and obstructed the mass movement of workers and peasants, and handed over the armed forces of the workers and peasants at a critical juncture in the revolution. On April 12 and July 15, 1927, Chiang Kai-shek and Wang Jingwei launched counter-revolutionary coups in Shanghai and Wuhan, and the first domestic revolutionary war (i.e. the Northern Expedition War) was defeated. The generals of the Northern Expedition who were about to go out took a photo at the Huangsha Station of the Guangdong-Han Railway. The person with a smile is the commander-in-chief of Chiang Kai-shek's Northern Expedition Army, He Yingqin, the commander of Chiang Kai-shek's First Army, Tan Yankai, the commander of the Second Army, Zhu Peide, the chief of general staff of the Third Army and the commander of the Fourth Army, Li Jishen, the commander of the Fifth Army, Li Fulin, the commander of the Sixth Army, Cheng Qian, the commander of the Seventh Army, and Li Zongren, the commander of the Eighth Army. Tang Shengzhi commented: The Northern Expedition War was a just war against the warlords of the Northern Ocean. The reason why it achieved such a huge victory was because it received the support and support of the broad masses of workers and peasants, which
