Dagukou has always been a coastal defense fortress in China during the Ming and Qing Dynasties. It is located at the mouth of the Haihe River. It is about 170 kilometers away from Beijing in the northwest, borders the Bohai Sea in the east, the Haihe Plain in the west, and faces Tanggu across the river.
"The land is at the strategic point of Jiuhe and Tianjin, and the roads connect seven provinces with boats and cars." Dagukou is known as the gateway to Beijing and Tianjin and the throat of land and sea. As early as the second year of Yongle in the Ming Dynasty, after Zhu Di, the founder of the Ming Dynasty, established his capital in Beijing, he built cities and garrisons in Tianjin.
Gun towers were built at Guhaikou; in the Qing Dynasty, the Dagu Xie town camp was set up; after the Ming army regained control of Jiangnan, the north and south forts of Dagu were built, and the number of gun positions and defense troops increased from 2,000 to 8,000.
However, when the Ming fleet used feints to harass, the Qing court found that Tanggu's defense force and system were still not complete enough. Because the area to be defended was not just a small area, including the north bank, south bank, Caotougu, and
Stone Gap, South Beach, etc., these places form part of the defense system of Dagu Fortress.
Moreover, for landing operations, if there are ready-made port facilities, it can certainly speed up the speed of transporting troops and supplies ashore. If not, it is not an insurmountable difficulty.
In other words, the Ming army could choose Tianjin and Tanggu as their breakthrough points, or they could choose other places to land. Of course, Tianjin is the biggest threat, but other areas cannot be ignored. Moreover, after the Ming army successfully landed on a large scale, if only
Based on the garrison in Tianjin, it seems that the strength of the troops is somewhat insufficient, or the defense depth is not enough.
Based on this analysis, if the banned Eight Banners are mobilized and rushed to Shandong, the safety of the capital cannot be effectively guaranteed. And the movement of the capital will not only bring military impact, but also comprehensive political passivity. Regarding the current isolated situation,
As well as the internal instability, the Manchus and Qing Dynasties still saw it relatively clearly.
Therefore, the Manchu and Qing Dynasties did not dare to ignore the safety of the capital and risk all their chips in Shandong. In other words, the Qing government changed the place where troops were mobilized and mobilized troops from the Xuanfu and Shanhaiguan areas to reinforce Shandong.
Although the same increase in troops was sent, the deployment from the capital and from Xuanfu and Shanhaiguan was different. At least in terms of time, it was later in the evening, which undoubtedly gave the Ming army time to stabilize in Shandong.
On the other hand, although it was difficult for the Ming army to continue to increase its troops massively due to the limitation of grain and grass supplies, the work of raising supplies did not stop for a moment. This allowed the Ming army to adopt refueling tactics and increase the number of troops to two thousand every ten days.
Invest new forces in Shandong.
Being able to seize and occupy the base that controls the Bohai Bay is victory, and if it can attract and consume the Qing army's power in Shandong, it will also be a favorable strategy. With the current financial and human resources of the Manchu Qing Dynasty, the Ming army only needs to consume it for a long time
War is enough to bring down the Manchu Qing Dynasty.
The Ming court has realized that the most important thing for the final victory of the war is that it cannot give the Manchus time to adjust and breathe. After the water transportation is cut off, they can only resort to extortionate levies and expropriations to support the war. The people are resentful, and it is the Ming army that is boiling.
To act as a liberator is a key factor in gaining support.
In fact, just as Zhu Yongxing and others expected, in the process of attacking Shandong, the Yu Qisu tribes scattered throughout Jiaodong cooperated with the Ming army, making the war develop extremely smoothly. For example, Hao Jin from Qixia, Song Fan and Song Wan brothers from Laiyang
, Song Jicheng and his son, Jimo Huang Pei, etc. either caused chaos or opened the city to respond. Fierce and time-consuming siege battles almost did not happen in the early stage.
After the Ming army's land and water armies joined forces and cut off the connection between the Jiaodong Peninsula and the interior of Shandong, those isolated counties had no intention of clinging to it and surrendered, and many surrendered.
Of course, this is also a manifestation of the disintegration of people's hearts within the Manchu and Qing Dynasties under the general situation after the entire reversal. And this situation is not limited to Shandong. The sudden rebellion in Huaiqing (Cao Henan Qinyang area) caused the Manchu and Qing Dynasties to lose control.
Even more shocked.
The Huaiqing area in Henan is close to Jifu. It is adjacent to Qin, Jin, Qi, and Chu, and is a "four-pronged" area. The stationed military commander is Hebei General Cai Lu. Cai Lu and Xiangyang Chief Military Officer Yang Laijia, who has surrendered anyway, are both former Zheng Chenggong
After the Ming army regained the south of the Yangtze River, Cai Lu received a rebellion letter from Yang Laijia brought by a secret agent of the Ministry of National Security.
He began to prepare for an attack. He secretly made shotguns, purchased mules and horses, and under the guidance of spies from the Ministry of National Security, ordered the soldiers to go out in armor in the name of fishing, but it was actually a military exercise.
Although it was planned that Cai Lu's uprising would have to wait for the right time, due to someone's informant, the Qing government received an urgent report that Cai Lu was going to take action, and immediately dispatched Minister of Internal Affairs Amida to lead the escort troops to Huaiqing (Qinyang, Henan), Cai Lu's garrison.
, "asking Cai Lu in detail why he fished" actually means arresting him and questioning him.
This information was learned by the Ministry of National Security, which immediately notified Cai Lu, allowing it to prepare in advance and respond urgently. When Amida led the escort to the eastern suburbs of Huaiqing, he was suddenly attacked by Cai Lu and his son, his nephew Cai Dingxi, and others.
He led his troops in an ambush, and under the attack of arrows, shotguns, and muskets, the guard suffered heavy losses, and Amida was injured and fled.
After Cai Lu and others defeated Amida, they immediately led the rebel officers and soldiers to break out of the encirclement with the treasury, grain, grass and baggage, and entered the Taihang Mountains to defend the area before the Qing encirclement and suppression army arrived.
From a military point of view, this was just a minor defeat for the Manchu Qing Dynasty, but from a political point of view, it was a crisis. Because Huaiqing already belonged to the Kinkifu region, the rebellion of Cai Lu and his son deeply shocked the Qing ruling group.
There is always a sense of crisis that makes them unable to sleep peacefully.
"It was not possible to extinguish it, but there was a commotion in Zhongzhou, and the soldiers and the people were restless!", "The people were worried, and the chaos was difficult to contain!"...
Urgent reports came one after another, making the Qing court even more aware that the security of the capital had been or was about to be threatened. Originally, Amida was sent to rush to Huaiqing to catch Cai Lu by surprise. He did not wait for Cai Lu to deploy and resist, but was caught off guard.
He was captured, and "pacified his army", so that "the north and south of the Yangtze River were blocked as before". However, they did not expect that the failure of the operation would cause more rebellions, and it was in the Jifu area, so the Qing government had to worry.
The rebellion of Cai Lu and his son had more than this impact. The Qing court, which was originally worried about the Green Camp and Han officials and generals, became more vigilant at this time. However, if precautionary measures were to be taken, it would undoubtedly weaken the Green Camp's combat effectiveness.
Increase the centrifugal tendency of green camp soldiers.
Obviously, the Manchu and Qing Dynasties were caught in a dilemma. They had to take advantage of the green camp while also taking precautions. Although this situation had existed for a long time, the effects were naturally different due to different situations. When the Manchu and Qing Dynasties were on a winning streak
, even if the Green Camp had complaints, they did not dare to resist; but after the Manchu Qing Dynasty became weak, thoughts turned into actions, and the chances doubled. (To be continued)
