How did Zhou Yu use the double agent against Jiang Gan? How did Jiang Gan do it?

Zhou Yu is a resourceful general in Jiangdong Sun's Group. He used the double agent to get rid of Cao Cao's two effective water army generals at one fell swoop.

It turns out that Cao Jun's soldiers are mostly northerners and don't learn to fight in water. After Cao Cao occupied Jingzhou, he used Cai Mao and Zhang Yun as commanders-in-chief, trained the water army and prepared for wiping out Jiangdong. Cai and Zhang, who have lived in Jingzhou for a long time, won the wonderful battle of water. Training the water army by them is obviously a potential threat to Jiangdong, and Zhou Yu is deeply worried. One day, Zhou Yu was discussing in his account when someone informed his old friend Jiang Gan of his visit. Zhou Yu made some arrangements for the generals, so he dressed up and went out to meet them.

This Jiang Gan, with the word Ziyi, has been a classmate of Zhou Yu since childhood and has a close friendship. Now she is a guest of honor under Cao Cao's account. This time, he came to Jiangdong on his own initiative to persuade Zhou Yu to surrender. In this regard, Zhou Yu naturally knows fairly well. So, as soon as he met, he "sealed" Jiang Gan's mouth: he ordered Taishi Ci, a general, to supervise the wine, claiming that "today is the day when old classmates meet, but when they talk about friends, they don't talk about the army, and those who have words will be beheaded immediately". Then, he boasted of Jiang Gan with the brave and magnificent soldiers in Jiangdong, mountains of hay and numerous civil and military heroes, which made Jiang Gan unable to speak. After the feast, Zhou Yu must sleep with Jiang Gan. He pretended to be drunk, lay down with his clothes on, vomited, and soon snored like thunder. That Jiang Gan couldn't sleep because of something in his heart. He got up on the second watch. When he saw that there was still a lamp in the account and there were papers piled on the table, he got out of bed and peeked. When he saw a surrender letter from Cai Mao and Zhang Yun to Zhou Yu, he couldn't help but be frightened and hid it in his body. At this time, Zhou Yu turned over in bed and talked in a dream, saying that Jiang Gan should look at Cao Cao's head in a few days. Jiang Gan hurriedly put out the lights and went to bed.

It was nearly four o'clock when someone came into the account and called, "Are you awake?" Zhou Yu pretended to be awake from a dream and deliberately asked the man, "Who is sleeping in the bed?" The man replied, "The viceroy invited Ziyi to sleep together. How did you forget?" Zhou Yu said regretfully, "I was never drunk on weekdays, but I was drunk yesterday. I wonder what I said?" The man said, "There's someone coming from Jiangbei." Zhou Yu whispered, "In a low voice!" Also called: "Ziyi." Jiang Gan pretended to be asleep and didn't answer.

Zhou Yu and his entourage quietly walked out of the account, while Jiang Gan eavesdropped in the account. Just heard someone outside say, "Cai and Zhang both said,' We can't do it in a hurry.' "Behind the words because the voice is too small, can't hear you clearly.

after a while, Zhou Yu returned to the account and called, "Ziyi." Jiang Gan should not, still fall asleep with his head covered. Zhou Yu then undressed and went to bed. Jiang Gan thought to himself: Zhou Yu is a delicate person. If Cai and Zhang's letters are missing after dawn, will he be willing to break up with * *? Therefore, as soon as I arrived at the fifth watch, I sneaked out of the account while Zhou Yu was sleeping, called the children with me, and quickly rushed to the river to disembark and go back to Jiangbei.

Jiang Gan returned to Jiangbei to see Cao Cao. Cao Cao asked, "Ziyi, how are things going?" Jiang Gan replied: "Zhou Yu's elegance is beyond words." Cao Cao was very unhappy and said, "If things are not done, they will make people laugh!" Jiang Gan said, "Although I failed to convince Zhou Yu, I found out something important for the Prime Minister. Please keep everyone away. "

When the people around him stepped down, Jiang Gan took out the letter and told Cao Cao what he had heard. Cao Cao was furious: "How dare these two thieves be so bold!" Then he called Cai Mao and Zhang Yun to enter the account. Without allowing them to argue, he ordered the samurai to launch beheading.

In this way, before the great war started, two of Cao Jun's most effective generals in the water army were easily removed by Zhou Yu's counter-measures.
