When the Sichuan Army left Sichuan, it was generally considered as the "worst army" in China at that time, with insufficient equipment, ammunition, supplies and medical equipment. Fighting in Shanxi in winter, soldiers wear straw sandals. However, it is such an army that has made countless hardest and most tragic sacrifices in War of Resistance against Japanese Aggression and made great contributions to the national independence of the Chinese nation. The notorious Yangsen Division of the 20th Army in the Civil War was the first Sichuan Army to spend War of Resistance against Japanese Aggression in Sichuan. Since the Battle of Songhu, it has been the backbone of three battles in Changsha, and it annihilated the Masaru Kato team of the ninth Hunchenglv of the Japanese army in the third battle of Zhuyingshan in Changsha. The 26th Division of Sichuan Army, which participated in the Battle of Songhu, was one of the five divisions with the best record, with more than 4,000 officers and men. By the time it left the battlefield, there were only more than 600 people, with more than 85% casualties. In Nanjing Campaign, Sichuan Army 2 1 Army defended the southern line, among which 145 Division defended Guangde. The position fell under the siege of the superior enemy. Rao Guohua, the teacher, resolutely led the remaining battalion into the enemy lines in an attempt to save the position. In the end, because they were outnumbered, they fell into a tight encirclement and tried their best to save the country. The general refused to be a prisoner and killed himself with a gun. 144 division commander Guo Xunqi was also seriously injured in the battle. At the end of 37, the 22nd Regiment was incorporated into the Li Zongren Miscellaneous Army War Zone to participate in the Battle of Taierzhuang. 122 division commander Wang was ordered to be stationed in tengxian. The main force of the Japanese fifth division, Masahiro Semihara, stormed tengxian and bombed the city walls with heavy artillery planes. Mr. Wang personally directed the street fighting, but unfortunately he was killed by machine gun fire. After Mr. Wang's martyrdom, the officers and men of his department resisted from house to house until the last one. The wounded soldiers in the city refused to be captured, and they died with the enemy who rushed in with grenades. In the Battle of tengxian, more than 5,000 people in 122 Division suffered almost all casualties. Chenbu, one of the three divisions deployed in the border river and Longshan area north of Tengxian County, also suffered four or five thousand casualties. Under the leadership of Wang, the Sichuan Army122nd Division was killed in tengxian. In the end, more than 300 seriously wounded people in the city rushed out to fight with the Japanese army after the Japanese army broke the city, and the rest of the wounded who were unable to move rang the remaining two boxes of grenades with a smile to mourn the city. In this campaign, none of the soldiers of the Sichuan Army were captured, which won the respect of the whole country for the Sichuan Army. It was the great sacrifice of the Sichuan army that won the battle of Taierzhuang. Li Zongren once said with tears: "The Sichuan army was outnumbered and spared no expense to stop the enemy from going south and complete the combat mission, which was written as the most brilliant stroke in the history of the Sichuan army." The Lijiayu 47 Army, which had been fighting in southeastern Shanxi for a long time, was later organized into 3 16 Army and stationed in Henan. In the battle of central Henan, the upper command of the Kuomintang was ineffective, and the ministries in western Henan were out of control. 3 16 army was ordered to act as a cover because it was a miscellaneous brand. During the transfer process, the directly affiliated team unfortunately encountered the Japanese army, and the commander-in-chief Li Jiayu was killed on the spot, becoming one of the highest-ranking generals of Sichuan Army who died in the Anti-Japanese War. Strictly speaking, the Sichuan Army in the Anti-Japanese War was not a regular army of the China Army, but a local warlord. The troops are inferior to the Kuomintang Central Army in terms of equipment, military quality and treatment. However, in War of Resistance against Japanese Aggression, this unit won the reputation of "Sichuan Army can fight" and "No Sichuan Army can't be an army" for its fearless sacrifice.
