The Sichuan Army refers to one of the warlord factions during the Republic of China. It is very famous because of its outstanding performance in the Anti-Japanese War. During the Anti-Japanese War, when the Sichuan Army came out of Sichuan, people from all walks of life generally believed that it was China's "worst army" at that time. It was poorly equipped and lacked ammunition, supplies and medical equipment. When fighting in Shanxi in winter, the soldiers still wore straw sandals. However, it was such a unit that made countless arduous and tragic sacrifices during the War of Resistance and made great contributions to the cause of national independence of the Chinese nation. Including the Sichuan troops who came out to fight the war, a total of about 3.5 million Sichuan people took to the battlefield. In other words, approximately 1 in 15 Sichuanese were on the front line of the Anti-Japanese War; 1 in 5 anti-Japanese soldiers nationwide was a Sichuanese [1]. The Yang Sen Division of the 20th Army, which gained notoriety during the Civil War, was the first Sichuan Army to fight in Sichuan during the Anti-Japanese War. Starting from the Battle of Songhu, it served everywhere and was the backbone of the three Changsha Battles. It also participated in the Third Changsha Battle at Zhuying Mountain. During the battle, the Kato Brigade of the Japanese Ninth Mixed Brigade was completely wiped out. The 26th Division of the Sichuan Army participated in the Battle of Songhu and was one of the five divisions with the best record. There were more than 4,000 officers and soldiers in the division. Only more than 600 people remained when they withdrew from the battlefield, suffering more than 85% casualties. During the Battle of Nanjing, the 21st Army of the Sichuan Army defended the southern front. Among them, the 145th Division defended Guangde. Under the siege of the superior enemy, the position was lost. Division Commander Rao Guohua resolutely led the remaining battalion into the enemy's position in an attempt to restore the position. In the end, he was outnumbered, trapped in a tight siege, and ran out of ammunition and reinforcements. The general did not want to be a prisoner, so he shot himself with a gun and died for his country. Guo Xunqi, commander of the 144th Division, was also seriously injured in the battle. The 22nd Group was incorporated into Li Zongren's Miscellaneous Army Theater at the end of 1937 and participated in the Battle of Taierzhuang. Wang Mingzhang, commander of the 122nd Division, was ordered to garrison Tengxian County. The fifth division of Seishiro Itagaki, the main force of the Japanese army, attacked Tengxian County fiercely and bombarded it with heavy artillery and aircraft. After destroying the city wall, Commander Wang personally directed the street fighting. Unfortunately, he was shot by a machine gun and died heroically. After Commander Wang died for his country, the officers and soldiers of his unit resisted from house to house, fighting to the last man. The wounded soldiers in the city did not want to be prisoners, and used hand grenades to kill the enemies who rushed in. In the battle of Teng County, almost all the more than 5,000 men of the 1st, 2nd and 2nd Divisions were killed or injured. The Chenli Division of the 31st Division, which was deployed in the Jiehe and Longshan belts north of Teng County, also suffered between 4,000 and 5,000 casualties. Under the leadership of Wang Mingzhang, the entire 122nd Division of the Sichuan Army died in Teng County. Finally, among the more than 300 seriously injured people in the city, those who were able to move after the Japanese army broke through the city rushed out to fight hand-to-hand with them and died for the country. The remaining wounded people who were unable to move smiled and fired the remaining two boxes of grenades together to die for the city. . In this battle, not one of the Sichuan soldiers was captured, which won the Sichuan army the respect of the whole country. It was the huge sacrifice of the Sichuan Army that led to the victory in the Battle of Taierzhuang. Li Zongren once said with tears: "The Sichuan Army outnumbered the enemy and did not hesitate to make heavy sacrifices to prevent the enemy from moving south, complete the combat mission, and write the most glorious page in the history of the Sichuan Army." The 47th Army under Li Jiayu fought in the southeast of Shanxi for a long time. It was later organized into the 36th Army and was stationed in Henan. During the Battle of Central Henan, the upper-level command of the Kuomintang was ineffective. The various units in western Henan were transferred in chaos. The 36th Army was therefore He was a miscellaneous man who was ordered to serve as a cover. During the transfer, the team directly under the headquarters unfortunately encountered a Japanese intersecting unit. Commander-in-chief Li Jiayu was shot and killed on the spot, becoming one of the highest-ranking generals of the Sichuan Army who died during the Anti-Japanese War. Strictly speaking, the Sichuan Army during the Anti-Japanese War was not a regular force of the Chinese army, but an armed force of local warlords. No matter the equipment, military quality, or treatment of the troops, they cannot be compared with the Kuomintang Central Army. However, during the Anti-Japanese War, this unit used its fearless sacrifice to gain the reputation of "the Sichuan Army can fight" and "no army can be formed without Sichuan". Its casualties ranked first among all provinces.
