Where is Pidao where Mao was stationed in the late Ming Dynasty?

Pidao, located in Korea Bay east of the Yalu River estuary, is a small island, only about 19 square kilometers. At first, it was called linden Island, which is said to be because linden trees were planted on the island. Later, when Mao arrived at the island, he chose it because his surname was Mao? The meaning of "the skin does not exist, the hair will be attached", and the island was renamed Pidao.

Mao first came to Pidao in November of the second year of the Apocalypse (1622). At that time, Mao attacked the Houjin fortress Zhenjiang (now Dandong City, Liaoning Province), and the Houjin lost a lot, so Houjin led an army into Korea to kill Mao. Considering that Houjin was not used to fighting in the water, Mao Longwen retreated to Pidao and used it as a stronghold to appease the refugees in Liaodong and contain the army of Houjin.

At that time, the geographical location of Houjin was really not a good location, because it was the Ming Empire in the south, the Korean Dynasty in the north, Mongolia in the west and Mao Longwen in the east. In other words, the post-Jin Dynasty was surrounded by Mongolia, Korea, Mao and Ming Dynasty. In this situation, the post-gold is actually very difficult to develop.

Because, no matter what direction the latter Jin develops, as long as its military main force stays away from its lair for a long time, all forces can take the opportunity to sneak attack on the latter Jin's lair and let them attend to one thing and lose sight of another, thus effectively curbing the development momentum of the latter Jin.

Of course, this is only an ideal state, because at that time, the armies of North Korea and the Ming Empire had lost their field capabilities, and Mongolia was beaten half to death by the latter. How dare they take the initiative to provoke the latter? In this context, although everyone knows that the lips are dead and the teeth are cold, many times, other forces are afraid to attack North Korea, the Ming Dynasty or Mongolia for fear of retaliation from the late Jin Dynasty.

Mao is the only exception. Because Mao's army was built from scratch, not the original decadent army of the Ming Dynasty, it was capable of fighting in the wild. More importantly, Mao's lair was at sea, and at that time, Houjin had no maritime power, so rushing out to sea was tantamount to dying, so Mao didn't have to worry about Houjin's revenge.

Although, Mao's military strength, compared with the latter, is not the same level of opponents. But the problem is that at that time, both Mongolia and North Korea silently supported Mao Longwen behind his back, secretly gave him money and weapons, and provided various conveniences.

In this context, after the military main force of the late Jin Dynasty left the lair, the armies of Mongolia, North Korea and Daming dared not sneak into the lair of the late Jin Dynasty, but Mao could. With the support of these forces, he can easily enter the territory of Houjin to harass, fight guerrilla warfare and even intercept the logistics supply of Houjin.

Because of Mao's existence, the post-Jin Dynasty naturally could not hold a large-scale labor expedition. At most, we can only severely attack the troops of Mongolia, North Korea or the Ming Dynasty on the border. As for the complete conquest of Mongolia and Korea, it is obviously very difficult, not to mention sending troops south to enter the Central Plains.

In fact, during the Nurhachi period and the early days of Huang Taiji, the external expansion of Houjin was always in a similar predicament. In other words, to achieve the strategic goal of conquering the Ming empire, the late Jin Dynasty must first unify the area north of the Great Wall, and to unify the area north of the Great Wall, it must first completely conquer Korea and Mongolia, but to completely conquer Korea and Mongolia, it is necessary to clean up the guerrilla group Mao.

However, the problem is that if the post-Jin Dynasty really wants to eliminate Mao, it must first completely conquer Korea and Mongolia. Otherwise, Mao and other forces will develop aimlessly at any time with the support of Mongolia and North Korea.

In this context, the late Jin Dynasty fell into an infinite cycle. If we want to conquer Mongolia and Korea completely, we must go on an expedition, and the time of the war will be lengthened, so that Mao can go deep into the enemy lines to fight guerrilla warfare, and the latter Jin will have to shrink the front line. If the latter Jin concentrated on attacking Mao and Mao ran back to the sea, Mao could quickly recover his strength because of the existence of Mongolia and North Korea, even if the latter Jin hit Mao hard.

In this sense, Yuan Chonghuan's killing Mao is indeed a bad move. Because after Mao Longwen was killed, Hou Jin finally got out of the predicament of being contained on all sides, and finally he could let go of his hands and feet to conquer Mongolia and North Korea. After the conquest of Mongolia and Korea, the so-called Ningjin defense line completely became a decoration.

Moreover, because Mao was killed by Yuan Chonghuan, another serious consequence was that all Mao's military groups collectively chose to take refuge in the Manchu Dynasty. We just need to know how strong this power is. There were four Han princes in Qing Dynasty, Kong Youde, Shang Kexi, Geng Zhongming and Wu Sangui. Except Wu Sangui, the other three are all from Mao.

Of course, when I said this about Mao Longwen, I exaggerated Mao Longwen's historical position. But in any case, Mao Longwen, as an important part of restricting the Qing Dynasty, was singled out by the Ming Empire itself, which was really a great blessing for the Qing Dynasty.
