Caocaodeng Bailangshan
Cao Cao's ascent to White Wolf Mountain dates back to the twelfth year of Jian 'an in the Eastern Han Dynasty (2007), and Wuhuan in the north gradually became stronger and merged into five counties: Shanggu, Yuyang, Youbeiping, western Liaoning and Liaodong. At that time, Kazuo belonged to Right Beiping County (now Lingyuan). At the end of the Eastern Han Dynasty, Wuhuan in Liaodong, Liaoxi and Youbeiping formed a powerful tribal alliance and occupied the western Liaoning region with Liucheng (now Chaoyang Yuantaizi) as the political center, which was called "Wuhuan in three counties" in history. Tower shield is the best, the first of the three counties. At this time, the Central Plains competed with each other, and Yuan Shao, who dominated the north, joined forces with Wu Huan to destroy Gongsun Zan. In A.D. 199, after Yuan Shao occupied Youzhou, in order to reward Wu Huan, he named all the leaders of Wu Huan Khan in the name of Emperor Xian of Han Dynasty and married Wu Huan. Yuan Shao personally married his daughter to Ta Dun, the leader of Wuhuan in the three counties. After Yuan Shao was defeated by Cao Cao in Guandu, his second and third sons, Yuan Yuan, went to the tower pier to "redraw Jizhou" in an attempt to recover his hometown. So Cao Cao decided to make an expedition to the Tower Shield to get rid of future troubles. Before the war, all the generals thought it was inappropriate, but Guo Jiali, the counselor, led an expedition to Tatton on the grounds that Tatton was defeated without fighting and Qinghai and Hebei were unstable. Cao Cao was also worried that Liu Bei, the former shepherd of Yuzhou, encouraged Liu Biao, the former shepherd of Jingzhou, to take the opportunity to attack Xudu (now Xuchang, Henan). Guo Jia thinks that Liu Biao is suspicious and indecisive. He knows that he is not as good as Liu Bei, and he is afraid that Liu Bei will surpass himself. He will never listen to Liu Bei's ideas. Cao Cao immediately sent his troops north to Yizhi (now northwest of Xiongxian County, Hebei Province), accompanied by his son Cao Zhi and general Zhang Liao. Cao Cao also took Guo Jia's advice, attacked thousands of miles, and dispatched troops quickly. He ordered all the trench to be left behind and led the light cavalry to March day and night. At the same time, please ask Tian Chou, a hermit, to be the magistrate of Gou County as a guide. When Cao Jun passed through Jixian County (now Tianjin), it was in the rainy season, and the road was muddy. Cao Cao took Tian Chou's advice and set up a big wooden monument on the roadside, which read: "This summer, the road is blocked, and once it is autumn and winter, it will be a heavy March." To confuse and paralyze Wu Huan. While bypassing Xu Wushan, I climbed the rugged path, left Lulong Village, trudged more than 500 miles, passed Baitan, Pinggang and Xianbei Pavilion, and pointed eastward to Liucheng. 200 miles away from Liucheng, Wu Huan's army found that Ta Dun, Yuan Shang and Yuan quickly joined Lou Ban Khan in western Liaoning and Nengchen Khan in Peiping. In August, I met Cao Jun in Bailangshan. Reflection? Shu Wei? It is recorded in the Chronicle of the Five Emperors: (Cao Cao) "In August, when we climbed the White Wolf Mountain, soldiers met Lu, and the crowds were very strong. The bus came first, few people were arrested, and both sides were afraid. Gong went up to the mountain, looking at the improper formation of Lu, and the soldiers attacked it, making Zhang Liao the pioneer, and the formation of Lu collapsed. The tower shield and the famous generals have been defeated, and Hu and Han surrendered more than 200,000 people. " Then Cao Jun conquered Liucheng in one fell swoop. Yuan Shang and Yuan went to see Gongsun Kang, the satrap of Liaodong County, and Cao Cao adopted Guo Jia's plan. Instead of pursuing, he sat and watched the situation, claiming that he would wait for Gongsun Kang to send Er Yuan's head. Jun withdrew from Liucheng in September, and soon, as expected, Gongsun Kang killed Yuan Shang, Yuan and Liaodong Khan Supu Pill, and dedicated his head to Cao Cao to show his loyalty. After Cao Cao defeated Wu Huan and wiped out the remnants of Yuan completely, except that the Kansai region was still occupied by Marten and Han Sui, the north was basically unified. Cao Cao's war to unify the north ended the long-term separatist melee in the north, pacified the northern border and created basic conditions for the further development of the northern society.
Look at how heroic Looking at the Sea is, which is based on the victory of a great man and hero:
On the east coast, climb Jieshi Mountain to see the vast sea.
The sea is so vast that the islands stand high on the sea.
Trees and paraquat are very lush. Autumn wind makes trees make sad sounds, and the sea is surging.
The movement of the sun and the moon seems to come from the vast ocean.
A trip to the sun and the moon, if unexpected;
Han is a talented star, if you take him by surprise.
I am glad to use this poem to express my inner desire.
