In the autumn of the twenty-fourth year of Jian'an (219), Guan Yu was secretly attacked by Sun Quan's troops in the "Battle of Xiangfan", and the soldiers were defeated and killed, and Liu Feng and Meng Da, who were stationed in Shangyong, surrendered to Cao Wei because they did not send troops to rescue Guan Yu, resulting in Guan Yu's defeat, the consequences were serious, Liu Bei was angry, Meng Da felt bad, and then surrendered to Cao Wei with more than 4,000 families.
The Wei Luo records that more than 4,000 families led by Yan Kang in the first year of The Year of Yan Kang returned to Wei.
Meng Da later wrote a letter to persuade Liu Feng to surrender, but Liu Feng did not surrender, Zhuge Liang believed that Liu Feng was fierce, and after a hundred years, no one could control him, suggested that Liu Bei take this opportunity to get rid of Liu Feng, Liu Bei agreed, and Liu Feng was forced to commit suicide.
Meng Da surrendered to Cao Wei, made Cao Pi very happy, and immediately made Meng Dajia an official and rewarded Meng Da heavily.
Meng Da was under Liu Bei, only as Liu Feng's deputy, Zhen Shou Shangyong, at best a Taishou, before, Meng Da was given the title of Yidu Taishou by Liu Bei, and when he arrived at Cao Wei, Cao Pi made him a Scattered Horse Changshi and a Jianwu general, and feng pingyang Tinghou, and then, combining the three counties of Fangling, Shangyong, and Xicheng to form Xincheng County, with Meng Da as the Taishou of Xincheng.
The Chronicle of the Three Kingdoms, Liu Feng's Biography, records that Emperor Wen of Wei's posture of Shanda was talented and contemplative, and he thought that he was a general of The Scattered Horse and a Jianwu general, and was enfeoffed as the Marquis of Pingyang Pavilion. The three counties of Hefangling, Shangyong and Xicheng are Xincheng County, and the three counties of Hefangling are the new city of Taishou.
Among them, it is worth noting that Meng Da took more than 4,000 families and surrendered to Cao Wei, how many people were there? Did this move hollow out the whole Shangyong?
Let's look at Meng Da's men, who are they?
At the beginning, when Liu Bei entered Sichuan, Liu Zhang of Yizhou sent Meng Da and Fazheng, each with two thousand people, to greet Liu Bei, and Liu Bei asked Meng Da to merge with Fazheng's two thousand people and garrison Jiangling.
The Chronicle of the Three Kingdoms, Liu Feng's Biography, records: In the beginning, Liu Zhang sent Fufeng Meng Da's deputy Fa Zheng, each with 2,000 generals, to welcome the first lord, and the first lord to lingda and lead his people, and stayed in Tun Jiangling.
That is to say, Meng Da commanded four thousand people, and these four thousand people should be Meng Da's family foundation.
Later, after Liu Bei captured Yizhou, Feng Mengda was made the Taishou of Yidu, and in the twenty-fourth year of Jian'an (219), Liu Bei ordered Meng Da to attack Fangling from Zigui, and then, attacking Shangyong, Liu Bei was worried that Meng Da alone could not command this territory, so he sent Liu Feng to Shangyong and took over Meng Da's army, Liu Feng actually became a leader of Shangyong, and Meng Da became Liu Feng's deputy.
Liu Bei's operation, nominally worried that Meng Da could not be alone, was actually a distrust of Meng Da, after all, Meng Da was not his own concubine, not a confidant, Liu Bei was definitely not at ease, so he arranged for his righteous son Liu Fenglai.
The Chronicle of the Three Kingdoms liu fengchuan records that after Shu Ping, YiDa was the capital of Yidu Taishou. In the twenty-fourth year of Jian'an, Fengda returned from Zi to the north to attack Fangling, and Fangling Taishou Puqi was killed by Dabing. Da will attack Shangyong, and the first lord Yin is afraid that Da yong will be alone, but he will send the army from Hanzhong to take the underwater to unify the Da army and meet with Da.
At this point, under the command of Liu Feng and Meng Da, Meng Da's original four thousand men, plus Jiangling, Zigui, Fangling and Shangyong, should have more than 10,000 troops.
This more than 10,000 troops, if there are also family members, conservatively calculated according to a family of three, it should be said that there are more than 30,000 people, plus the local people, there should be 40,000 or 50,000 people.
When Meng Da surrendered to Cao Wei, he took away more than 4,000 families, which should be Meng Da's original 4,000 people, they married and had children, and each formed a family, if a family is calculated according to three people, the whole part has about 10,000 people.
No wonder Cao Pi was so happy to see Meng Dalai surrender?
Suddenly there were more than 10,000 people, and in ancient times, population was the largest resource, which meant military resources, logistical supplies, taxes, and so on.
During Zhuge Liang's first Northern Expedition, because Ma Mo lost the street pavilion and Zhao Yun lost the battle in Jigu Valley, he was forced to withdraw his army, and when Zhuge Liang withdrew, he moved more than a thousand people from Xi County and returned to Hanzhong.
The Chronicle of the Three Kingdoms, The Biography of Zhuge Liang, records that more than a thousand families in Liangbaxi County were still in Hanzhong.
Population is an important resource in the war, the population of the Shu Han Dynasty was originally small, Zhuge Liang could not help but consider this problem, so he moved away more than a thousand people in Xi county.
Meng Da surrendered to Cao Wei and took away more than 4,000 families, which was four times more than zhuge Liang's more than a thousand people who moved from Xi County to Hanzhong.
No wonder Cao Pi was so happy that he couldn't close his mouth, Bai picked up so many people!
