After the defeat of Kolchak's army, the Entente shifted the focus of the war to the south of Soviet Russia and decided to launch a second offensive with Denikin's army as the main force. In July of the 10th year of the republic, Denikin ordered the capture of Moscow, dividing his troops from the west bank of the Don River to the Volga River and attacking north. Fighting on the front line of Kursk, Oryol, and Tula in the direction of the main assault was Denikin's elite unit "Volunteer Army". On 9 July, the Central Committee of the Peasants' and Workers' Party and François issued a call for "everyone to fight against Denikin." In August, the Southern Front of the Red Russian Army, on the orders of the headquarters, launched a counteroffensive and attacked Denikin's Kuban base camp from the flank, but without success. On September 12, Denikin's army again launched an offensive in the Kursk-Oryol direction, and by mid-October it had occupied Kursk, Voronezh and Orel, directly threatening Tula and the capital Moscow. Yudenich's army also again broke through the Red Army lines on the Western Front, reaching the outskirts of Petrograd in mid-October.

In order to adapt to the new operational situation, the Red Russian Army Command divided the Southern Front into the Southern Front and the Southeast Front in late September. In October, the Central Political Bureau of the Peasants' and Workers' Party decided to hold Tula and Moscow, concentrating its basic forces on the southern front, while the Southeastern Front temporarily moved to the defensive. On October 11~12, the Southern Front, under the leadership of Commander A.I. Egorov and Military Commissar Joseph Zhulishkov, launched a counteroffensive in the Orol-Kromé and Voronezh regions, and by mid-November they had recaptured Orel, Voronezh and Kursk. After that, the counteroffensive on the Southern Front developed into a general offensive of two fronts: the Southern Front fought in the Kharkov, Rostov directions; The South-Eastern Front attacked Novocherkassk on the right flank and Tsaritsyn on the left flank.

In December, the Red Russians liberated Kharkov and Kiev, and in January of the following year, they captured Tsaritsyn and Rostov. As a result of the capture of Rostov by the Red Russian army and its advance to the coast of the Sea of Azov, Denikin's forces were divided into two isolated groups, one retreating to the Caucasus, the other to the Crimea and Odessa. Taking advantage of the victory, the Red Russian army pursued Odessa in February and Novorossiysk in March. After the remnants of Denikin fled to the Crimea, they were taken over by P.N. Wrangel, who was routed by Frunze in the Crimea a short time later. At this time, the Red Army also achieved significant victories on other fronts. On the Western Front, Yudenich's second offensive on Petrograd was repulsed, and its remnants fled into Estonia and were disarmed; On the northern front, the Red Russian army liberated Arkhangelsk in March of the 11th year of the Republic and confronted the 66th Division of the Chinese Expeditionary Force stationed in Murmansk across the sea; On the Eastern Front, the Red Russian army switched from the upper Yenisei River to a new offensive in the autumn of the 10th year of the Republic, and by January of the following year Kolchak's troops were again routed, and Kolchak led the remnants of his army to retreat along the railway to the Trans-Baikal region. Due to the occupation of the Irkutsk region by the Northern Chinese Dispatch Army, several attempts by the Red Russians were routed by the tanks and planes of the Dispatch Army, and after tens of thousands of casualties, Tukhachevsky decided to lead the First Army to retreat to Tulum and confront the Chinese White Bandit Army by relying on the geographical advantages of the Eastern and Western Sayan Mountains and the Angara River.

After the end of World War I, Germany withdrew its troops, the Red Russian army helped Ukraine establish the Red Regime, and Pilsudski's fascist dictatorship, supported by a large amount of funds and weapons and ammunition from the forces of imperialist capital, launched an offensive on April 25, the 11th year of the Republic, and occupied Kiev on May 7. The Red Russian army switched to a counteroffensive on 26 May and reached Warsaw in mid-August. Due to the long front, the two armies of Red Russia were forced to retreat after the Polish counteroffensive was launched. On October 12, the two sides signed an armistice agreement in Riga, ending the First Russo-Polish War.

At this time, Russia was already devastated, and Russia had been at war for seven consecutive years, including the First World War. During this seven-year period, 20 million people died, and 300,000 surrendered to Poland. During the civil war, more than a million people died on both sides, and the country's economy almost collapsed, which was exacerbated by the drought of the 11th and 12th years of the Republic. Disease was also rampant, with three million people dying of typhus and millions more from the massacres of both sides in the 11th year of the Republic alone.

During this period, a million people fled Russia to Europe or the Baltic states, and of course some to China, where they were called White Russia. Many of these people are well-educated professionals who have played an important role in the construction of these countries. However, Red Russia, which had made full use of these talents in history and rose rapidly, lost the opportunity to become an industrialized power because of the loss of talents.

After the First World War, China did not reduce its armed forces as Britain, France and the United States as it did in the first half of the Republic, but in May of the tenth year of the Republic, the Ministry of National Defense held an arms policy seminar in Jinan, at which the Chinese military determined the outline for the next step in the development of the army:

The Seventh, Eighth, Ninth, Tenth, and Center Armies of the original Army had already sent troops to fight in World War I, the war of intervention against Russia, or the war of internal unification, and about one-third of the veterans and noncommissioned officers of these tried and tested units were reduced.

At the same time, through the recruitment offices in various localities, non-commissioned officers and students will be recruited from among young people with junior high school diplomas or above, and professional soldiers will be recruited from among young people in rural areas, and the non-commissioned officers and students will be assigned to the military training bases run by various group armies for six months of concentrated military training and squad management training. The recruited soldiers and non-commissioned officers will fill the vacancies in the various units and will form a retirement mechanism for soldiers and non-commissioned officers in the future, and soldiers will generally be discharged from active duty after 4-6 years of service. And non-commissioned officers can serve for 5-10 years. Retired soldiers will become members of the first-class reserve within 5 years after retirement, and will receive 50% of the worker's income equivalent to a certain number of years as a training allowance every month, and the retired soldier will also receive a retirement grant and a recommendation to work in major chambers of commerce and enterprises, which also makes joining the army a shortcut for many rural young people to change their destiny.

Except for those who have been reduced from the ranks of non-commissioned officers and soldiers due to physical reasons or voluntary retirement, they will be transferred to the internal affairs units that have just been reorganized from patrol battalions, and all provincial-level units throughout the country will establish internal affairs units. The soldiers of the internal affairs forces are mainly soldiers of the militia of warlords or revolutionary parties who have been incorporated from various localities, as well as some civilian armed forces such as militia groups and joint defense units. Through the training of non-commissioned officers and soldiers who had retired from the National Defense Forces, a number of internal guard units of more than 400,000 men were formed, after eliminating some personnel who were not suitable to remain in the armed forces.

Lieutenant General Zhang Shaozeng, commander of the Internal Guards, announced in Jinan on 1 October of the 10th year of the Republic of China that China's internal guards were formally organized into 43 columns and several regiment-level coastal guard units. Basically, every province or region has a column (division) of internal affairs troops stationed in the local area, completely liberating the national defense forces from the task of maintaining domestic stability and making the national defense forces a completely independent field corps.

At the same time, the Ministry of National Defense announced the establishment of six military regions, namely:

The Central Military Region, with Jinan as its headquarters, has jurisdiction over nine provinces and municipalities including Shandong, Hebei, Shanxi, Henan, Anhui, Jiangsu, Shanghai, Beiping, and Tianjin, as well as 11 internal guard columns and four coastal patrol units.

The Northeast Military Region, with Harbin as its headquarters, has jurisdiction over five provinces: Liaoning, Jilin, Heilongjiang, Dongmeng, and North Xing'an (the recovered area of the Outer Xing'an Mountains), six internal guard columns, and one coast guard unit.

The Southeast Military Region, with Guangzhou as its headquarters, has jurisdiction over seven provinces, namely Guangdong, Fujian, Zhejiang, Hubei, Hunan, Jiangxi, Taiwan (which has not yet been recovered), and Hainan, as well as eight internal guard columns and five coastal guard units.

The Southwest Military Region, with Chengdu as its headquarters, has jurisdiction over five provinces, Sichuan, Guizhou, Yunnan, Guangxi, and Tibet, and six internal guard columns.

The Northwest Military Region, with Lanzhou as its headquarters, has five provinces under its jurisdiction: Shaanxi, Gansu, Southern Mongolia, Qinghai, and Xinjiang, and five internal guard columns.

The Northern Military District, with Kyakhta as its headquarters, has jurisdiction over seven border provinces, North Mongolia, Simon, Balkhash, West Kunlun, Samarkand, Turkestan, and South Baikal, and seven internal guard columns.

F-FDTL units have been returning home one after another. With the exception of the 66th Rapid Response Division, which was stationed in Murmansk, all five Chinese armies had already returned to their positions. After the tempering of the European war, the technical and tactical level of the Chinese National Defense Forces has been rapidly improved, and in contrast, only the 3rd and 5th Divisions participated in the Eastern Front operations, where the intensity of confrontation was very poor. The Japanese Army did not gain the corresponding battlefield experience in World War I, especially in the use of armored forces, and the gap between the Japanese Army and the Wehrmacht widened.

The more than 800,000 field armies within the five group armies are composed of 39 divisions, 4 division-level heavy artillery clusters, and an unknown number of regiment-level special combat groups. Thanks to the fact that China became the world's arsenal in World War I, China became the world's largest production base in armored vehicles and transport vehicles, and nearly two-thirds of these army divisions were mechanized infantry divisions or enhanced motorized infantry divisions, as well as six mountain divisions composed of veterans of the original Wehrmacht and soldiers from the mountainous areas of the southwest region, and six rapid reaction divisions that were all wheeled and armored.

Of course, the most special thing is the four foreign motorized infantry divisions composed of the remnants of Kolchak and some former Belarusian soldiers, although these foreign infantry divisions are under the control of the Chinese Defense Forces, they are not within the establishment of the Wehrmacht, they are regarded as foreign regiments of the Wehrmacht, stationed in the Baikal region and the Astana region, and become auxiliary units of the Northern Dispatch Army. Although it is an auxiliary force, the regular equipment of the Chinese National Defense Force, which is fed and clothed, is a hundred times stronger than the "Russian Restoration Army" of Kolchak, who was defeated and lost his soul. In fact, if calculated purely on the basis of combat effectiveness, the Russian Restoration Army can already be denaturalized, and the more than 30,000 people under Kolchak can no longer be regarded as a regular army, except for a few thousand rifles. As a last resort, Lieutenant General Du Zicheng had no choice but to allow them to retreat to the Ivanovsky area to recuperate.

When the third reorganization of the Wehrmacht was in full swing, it attracted the attention of the world's great powers, especially Japan, who almost sent out agents in China to find out the news. Almost at the same time, the expansion of the Standard Air Force, which had been glorious in World War I, became another hot spot for the Chinese military, but no one paid attention to the Wehrmacht Navy that sailed two cruisers and four destroyers back to the Chinese port of Qingdao from the North Sea, thousands of miles away.
