The famous Southern Song Dynasty general Yu Yunwen was defeated in the battle of quarrying

Yu Yunwen was a famous minister of the Southern Song Dynasty. Word Bingfu. A native of Renshou (present-day Sichuan). In the twenty-fourth year of Shaoxing (1154), he ascended to the rank of Jinshidi, and was promoted to the Zhongshu Sheren and Zhixue Academy. Thirty-one years after Shaoxing, King Yan Liang of Jinhai led the main force of the Jin army across the Huai River and into the Yangtze River. The Song army on the two Huai fronts collapsed, the Jin army entered no man's land, and the Southern Song Dynasty was once again in jeopardy. Yu Yunwen was then a military staff officer of the Jianghuai Army, and was sent to Quarry (in present-day Ma'anshan, Anhui) to serve as a division, just as the Jin Hailing King's army was plotting to cross the river from Quarry. Seeing that the situation was critical, Yu Yunwen resolutely organized the scattered troops along the river and had no command, foiled the Jin army's plan to cross the river and invade the south, and won the famous "quarrying victory".

In the thirty-first year of Shaoxing (the sixth year of Jin Zhenglong, 1161), the Jin Emperor completed Yan Liang in the autumn of the sixth year of Zhenglong, mobilized 320,000 troops, and sent troops in separate ways in an attempt to destroy the Song in one fell swoop. At the beginning of October, he led the main force of 170,000 into the north bank of the Huai River, intending to cross the Huai River from Shouchun (present-day Shou County, Anhui). The Southern Song Dynasty, who served as the defense of Western Huai, ruled the kingship of Jiankang, and the Jin army attacked without resistance, resulting in the Successful Crossing of the Jin Army. The Song army retreated to Hezhou (河州, in modern Hexian County, Anhui), and the generals asked for battle one after another, and the king falsely claimed to abandon the city and defend the river, so he fled by boat first, and the people were defeated and retreated to the quarry. After Yan Liang entered Hezhou, he demolished the house and built the ship, preparing to cross the river in early November.

The king's army collapsed without a fight, which seriously threatened the natural danger of the Yangtze River that the Southern Song Dynasty relied on. In order to save the crisis, the Song court relieved him of his royal power and ordered Li Xianzhong, the commander of the armies, to be responsible for the defense of Jiangsu, and sent Yu Yunwen, a staff officer of the Mafu Commandery of the Jianghuai Army, to urge Li Xianzhong to take up his post and go to the quarry division. On the eighth day of the first month of November, Yu Yunwen went to the quarry, saw that the situation was critical, and in the emergency situation that Li Xianzhong had not arrived and the Jin army was about to cross the river, he gathered 18,000 troops and took the initiative to command the Jin army. He hid his infantry behind the high ground and waited in a tight position. The sea loach ships of the dividing army were five teams: one was in the center, the two teams were on the east and west wings, carrying elite troops, and the militia of Dangtu (now part of Anhui) rode on their bicycles, and the military and civilians cooperated to intercept the Jinjun boats; the two teams hid in small ports as reserves. A large number of boats of the Jin army sailed out from the mouth of the Yanglin River, and some of the ships rushed away from the Song warships and forcibly landed. Yu Yunwen went back and forth to command the generals to meet the battle, and the general Shi Jun and other generals saw Yu Yun tattooed as a pioneer soldier, so he led the soldiers to fight bravely and immediately destroyed the landing Jin army. The sea loach boats rushed back and forth in the river, and fired thunderbolt cannons, and the Jin soldiers would fall into the water one after another, and in the middle of the river, the remaining ships retreated to the Yanglin River. Yu Yunwen decided that the Jin army would attack again, and that night, Shi Jun led a loach boat to control the mouth of the Yanglin River. After Yan Liang was unable to cross the river, he was forced to lead his army to Huaidong on the twelfth day in an attempt to cross south from Guazhou (present-day Hanjiang, Jiangsu). Yu Yunwen saw through the intention of the Jin army to go east, so he led his army to the aid of Zhenjiang (in present-day Jiangsu) at night. When Yan Liang knew that Yan Yong was proclaimed emperor in Tokyo (present-day Liaoyang, Liaoning), he ordered his troops to cross the river within three days. The generals knew that crossing the river would be defeated, and on the twenty-seventh day, some of the soldiers would break into the imperial camp and kill Yan Liang. The Jin army retreated north.

In this battle, Yu Yunwen stepped forward at an urgent moment to organize and command the quarry soldiers and civilians to meet the Jin army.

Because of his proper deployment of troops, decisive command, and giving full play to the song army's superiority on the water, he turned the tide of the war and turned defeat into victory.
