For the defending side, in addition to the problem of proper and efficient disposal of corpses to avoid the outbreak of plague in the city, there is also a very important issue to deal with, that is, the problem of water sources. Pen, Fun, Pavilion www.biquge.info (.)

In many cases, the defense system of a city will vary from place to place for the defenders.

Just like in the war of Qin's annihilation of the Six Kingdoms, the loss of Daliang City was not caused by the lack of water sources, but on the contrary, the water sources around Daliang City were too abundant, which led to the development of Daliang City because of the development of the water conservancy system, Wang Ben found a way to flood Daliang, and finally captured this fortified city that gathered the last strength of Wei and planned to defend to the death.

The same example is also in the Warring States Period, there are also examples of Bai Qi digging Bai Qi Canal and flooding Yan City.

Of course, it is also an example of water attack, but there is no doubt that the two are in fact difficult to compare.

Because the difficulty of building the Baiqi Canal is much more difficult than Wang Ben's construction of a dam outside the city of Daliang to store water and flood the city of Daliang.

......

Baiqi Canal, also known as Wuzhen Baili Long Canal, Sandao River Long Canal, Xinchen Canal, is a great project created by the ancient Han working people, belongs to the military water conservancy project built during the Warring States Period, and the construction time is 23 years earlier than the famous Dujiangyan Water Conservancy Project.

Bai Qi Canal originally did not have a name, and the name of this hundred-mile long canal probably appeared after Bai Qi's death.

The description of Baiqi Canal in later generations is mainly as follows: "The Best of China's Water Conservancy" lists Baiqi Canal as "the earliest irrigation canal in China", which is located between Nanzhang and Yicheng in Hubei, and is a water conservancy project built during the Warring States Period.

The head of the canal starts from Xiejiatai 3.5 kilometers west of Wu'an Town, Nanzhang, and enters the Hanshui River at the mouth of the island near Chihu Village, Zhengji Town, Yicheng City in the east, with a total length of 49.25 kilometers. In addition, there are 38 branch canals, 126 canal buildings, and many other places, such as the "gourd" project (mainly referring to 10 small and medium-sized reservoirs and 2,671 weir ponds).

The Baili Changqu Irrigation Area includes 6 townships and 4 farms in Yicheng and Nanzhang, covering an area of square kilometers. It is known as the "three major water conservancy projects of the Qin Dynasty" together with Dujiangyan in Sichuan and Zhengguo Canal in Shaanxi.

The reason why the long canal is also called "Baiqi Canal" is that it was the war canal of the Qin general Bai Qi who used water to replace the soldiers and flooded the Yancheng of Chu (the ruins of the Chu Imperial City in Zhengji Town, Yicheng City).

The name of the long canal was first seen in the "Yuanhe County Atlas" in the Middle and Tang dynasties: "The long canal is twenty-six miles south of the county. The former Qin Dynasty made Bai Qi attack Chu, diverted two rivers from the western valley, and fought for Yancheng. ”

According to Song Zenggong's "Changqu Chronicles", it is recorded that in the twenty-eighth year of King Qin Zhao (279 BC), Bai was sent to attack Chu. After Bai Qi led his troops to attack Yancheng, when he was heavily guarded by the Chu State and could not be attacked for a long time, he took advantage of the geographical features and topography conditions of Yancheng and its surroundings to build a dam on the Yishui River section of the Hanshui tributary next to Wu'an Town, which was 100 miles away from Yancheng, and dig ditches to replace the soldiers with water and divert water to break Yancheng. The Battle of Yancheng in Qin, Chu and Yan was one of the fiercest and most brutal battles in history.

"History of Ancient Chinese Wars" and "Notes on the Book of Water" all record the war situation at that time: "The water broke the west wall of Yancheng, and the east city wall was broken, and the people flowed with the water, and hundreds of thousands of people died in the east of the city...... After the end of the war, Yan entered Qin, and Qin took Yan as a county. After that, the king of Qin named Bai as Wu'anjun, and Wu'an Town got its name from this. After the war, this canal was used to irrigate the fields, and the "war canal" became "irrigation canal", which was called the Baiqi canal.

In the later history, the southern county of the Han Dynasty was dug again, "irrigating 700 hectares". Therefore, the "Notes on the Book of Water" records that 3,000 hectares of fields were irrigated in Baiqiqu and 700 hectares were irrigated in Muligou. "Reading the Minutes of Reading History and Public Opinion" also has the same record: the long canal is forty miles west of Yicheng County, also known as Luochuan, also known as Yanshui, and also called Baiqi Canal, that is, Manshui. In the twenty-eighth year of King Qin Zhao, Bai Qi attacked Chu, went to Yan Baili and exhausted, and used water as a canal to irrigate Yan. Yan entered Qin, and the canal was not wasted, and now the long canal is also.

Historically, the civil system of Baiqi Canal was used and discarded due to different repair conditions:

According to the statistics of later generations, the head of the canal has been repaired, repaired and rebuilt 10 times, including the current Baiqi Tablet Pavilion, which preserves a large number of inscriptions and inscriptions of some cultural celebrities. Among them, the Tang, Song and Yuan dynasties have carried out five major repairs to the Baiqi Canal: respectively in the fourth year of the Tang calendar (769), in the second year of Xianping in the Northern Song Dynasty (999), in the second year of the Northern Song Dynasty (1055), in the first year of Longxing in the Southern Song Dynasty (1163), and in the ninth year of Yuan Dade (1305), which made it play a good irrigation benefit.

According to records: in the fourth year of the Tang Dynasty (769), Liang Chongyi built Wu'an Weir on the Manhe River, forty-five miles southeast of today's Nanzhang County. In the second year of Beilai Zhihe (1055), Yicheng County ordered Sun Yong to rebuild and formulate water management methods.

Song Dynasty Zhiping three years (1066), presided over by Yicheng County Ling Zhu Xiao, large-scale repair and expansion, in the head of the canal Lujia to build "Lingxi Weir", in order to intercept the high water, the canal water flows southeast, the lower channel is connected with 49 pi, and the downstream branch leads to the long canal. The irrigated area has increased significantly, reaching more than 6,000 hectares.

In the 32nd year of Shaoxing in the Southern Song Dynasty (1162), it was overhauled again, and 39 Tuntian were revived. In the tenth year of Chunxi in the Southern Song Dynasty (1183), it was overhauled, 46 buckets were built, and an irrigation water system was established. So much so that Li Daoyuan of the Northern Wei Dynasty wrote "Notes on the Book of Water", saying that its long canal "irrigated 3,000 hectares of fields".

The Northern Song Dynasty Zeng Gong wrote "Xiangzhou Yicheng County Changqu Ji" contains: "Li Daoyuan is said to irrigate more than 3,000 hectares of fields, and it has been more than 1,000 years so far." Song Zhengji's book "The Wooden Canal of Yicheng County, Xiangzhou" said that the Taishou Wang Pet of Hannan County re-dug the wooden canal and merged it (long canal) to "irrigate 6,000 hectares of fields". However, in the Ming Dynasty, the long canal was annihilated year by year, and gradually became completely obliterated.

In the Qing Dynasty, under the pressure of rapid population growth, the matter of repairing the long canal was put on the agenda of the government. In the twelfth year of Jiaqing (1807), the ninth year of Xianfeng (1809), and the thirty-first year of Guangxu (1905), the Yicheng County Order and the people of Yicheng County had asked for revision several times, but due to the conflict of interests between regions, the discussion could not be resolved, and it was unsuccessful.

In the 28th year of the Republic of China (1939), General Zhang Zizhong, commander-in-chief of the 33rd Group Army of the Kuomintang, was stationed in Yicheng County and telegraphed to the Hubei Provincial Government to restore it. In the 31st year of the Republic of China (1942), the long canal rehabilitation project broke ground. In order to commemorate Zhang Zizhong, the long canal was renamed as Xinchen Canal (张紩荩忱). The repair project was built for 5 years, but due to many factors, the repair process was not completed.

On the 26th, the Hubei Provincial Department of Water Resources held the province's first water conservancy meeting, after which the proposal for repairing the long canal was adopted. In January 1950, it was approved by the Ministry of Water Resources and listed as a loan project to support. In January 1952, Yinan and Yinan counties invested 40,000 laborers to start repair. On May 1, 1953, the restoration of the long canal was completed, and a grand ceremony was held at the head of the canal.

......

In terms of the situation of the Baiqi Canal, although the Baiqi Canal was repaired for military purposes at the beginning, I am afraid that Bai Qi himself did not expect that the hundred-mile-long canal he built would eventually become a famous water conservancy project that has been passed down through the ages.

There is an opinion that Bai Qi built this 100-mile long canal, which was relatively unreasonable in the military sense, mainly because the Qin army was unable to capture Yancheng, which was heavily defended.

According to this theory, hundreds of thousands of Chu soldiers and civilians under Yancheng gathered here and were forced to defend the city. Bai Qi is in a Jedi at this time, and his backup is cut off, so he must fight quickly and not delay. And the Yandu guarded by hundreds of thousands of troops can be taken by tens of thousands of horses in a moment. So Bai Qi led the army to Fengxiang County, a hundred miles west of Yanxi.

Bai Qi garrisoned in Fengxiang County. The main force of hundreds of thousands of Chu troops strictly guarded Yandu, waiting for the Qin soldiers to starve to death because of the logistics cutoff. However, Bai Qi sent thousands of Qin soldiers to build a dam in the town of Manhewu, about 100 miles away from Yancheng, and secretly built a 100-mile long canal from this tributary of the Han River to the east and west.

After the construction of the hundred-mile long canal, Bai Qi dug and released water to divert water to irrigate the city. In an instant, the souls of hundreds of thousands of Chu soldiers and civilians were scattered, and the rolling flood demons sent these hundreds of thousands of living beings into the bottomless abyss in an instant. The Yandu generation, Hongze is a piece, the city is full of fish and shrimp, and the river is full of corpses.

In this way, hundreds of thousands of Chu army elites were handled so easily by Bai Qi. Subsequently, Bai Qi led tens of thousands of elite Qin troops to carry out a series of defeats against the remaining Chu armies that had lost their central assembly points and were disheartened, and finally won a decisive victory in the Battle of Yancheng.

......

In fact, there are three errors in this view, the first is that the Qin army should have built more than thousands of people who built the long canal. Of course, it is also possible that Bai Qi asked the nearby civilians to join in the construction of the long canal, so that the long canal could be successfully built.

The second mistake is that the distance between the Baili Long Canal and Yancheng should not be so far, or that the wild water at that time happened to flow near Yancheng, and the Baili Long Canal was likely to be a reservoir that stored wild water, and finally successfully flooded Yancheng after releasing the water.

Because if the distance is too far, the water attack may not have enough effect, and the wild water itself is not a large water system, and if you want to have enough water attack power, distance is also a problem. Therefore, this statement is more reliable: the long canal is twenty-six miles south of the county. The former Qin Dynasty made Bai Qi attack Chu, diverted two rivers from the western valley, and fought for Yancheng.

The third mistake is that even if it is flooded, Yancheng has a certain defensive ability, and it is very likely that Bai Qi officially launched an attack on Yancheng some time after the flooding of Yuncheng.

If you look at it this way, it is also possible that the Chu army will reintegrate the defense system, but don't forget that if there are many people drowned inside and outside Yancheng, and if their corpses produce epidemic origins, then Yancheng will soon become an epidemic area, and its drinking water problems will also greatly contribute to the epidemic of corresponding infectious diseases.

Therefore, in the case of insufficient troops, Bai Qi is likely to choose to wait for a few days before launching an offensive against Yancheng.

Of course, this is a relatively risky military operation, because if Yancheng has become an epidemic area, then for the Qin army besieging the city, there will also be the possibility of infection.

And it is not impossible for the Qin army to cover up and kill Xiang Yancheng after the water attack, which can be regarded as an example.

An example of this is water irrigation in Jinyang.

In 453 BC, Zhi Yao sent an army to garrison the Fenshui embankment, ordered soldiers to dig soil and repair the embankment, and directed the Fenshui to Jinyang City, which became Wang Yangze overnight. Zhao Wuxian never expected Xun Yao to come to such a move, using the geographical and natural advantages to attack the city where people were stationed.

The soldiers and civilians in Jinyang City have begun to feel uneasy, and the crisis of the Zhao clan is coming.

Zhi Yao stood on a high place, looking down on Jinyang, quite proud of this unprecedented tactical feat he had made, and couldn't help but say: "I, Zhi Yao, have fought for half my life, and I really didn't realize the power of this river before! It can actually destroy a country!" Han Hu and Wei Ju were on the side, thinking in their hearts about their main city of fiefdom, similar to the situation in Jinyang, there was a river flowing nearby.

If Zhi Yao's words were a hidden threat, then they would also follow in the footsteps of the Zhao family.

Two months have passed, and Jinyang City is already eating with Yi Zi. Zhao Wuxian asked Zhang Mengtan: "What can I do about it?" Zhang Mengtan said: "Let me go out of the city to meet Han Hu and Wei Ju!" Zhao Wuxian agreed. On this night, Zhang Mengtan secretly infiltrated Han Hu and Wei Ju and said about the current situation: "If the Zhao family dies, Han and Wei will not be protected!" It was this sentence that hit the key point of Han Hu and Wei Ju, and his lips were cold and his teeth were cold. Duan Gui and Ren Zhang were also fanning the flames, so the two families negotiated an agreement with Zhang Meng to destroy the Zhi clan together, and an earth-shattering conspiracy took shape.

In March 453 BC, there was silence in the camp of the Jin army. Han Hu and Wei Ju led the two personal soldiers into the embankment of Fenshui, and took advantage of the unpreparedness of the Zhi clan to suddenly attack, killing all the Zhi clan's personal soldiers and controlling the embankment. Then the Fenshui was directed to the Zhi Shuai camp, and the water potential in Jinyang City receded. Zhao Wuxian knew that things were going according to plan, and led Zhao's personal soldiers to fight out of the city.

Zhi Yao was still in a dream at this time, and when he heard that there was chaos in the barracks, when he woke up, there was already an ocean around him, and the Zhi army was at a loss in the chaos. The Zhao clan fought out of Jinyang City, and the Han clan and the Wei clan attacked both sides of the Zhi clan from the left and right, and the Zhi army had become a turtle in the urn.

Zhiyao couldn't control the army and wanted to take the road and escape. At this time, Zhao Wuxian, who hated Zhi the most, led his troops to capture Zhi Yao alive and kill him, and also carved Zhi Yao's head into lacquer, as the head of drinking. The Han, Zhao, and Wei families continued to exterminate and surrender the remnants of the Zhi clan. The main forces of the Zhi clan were all annihilated in this battle.

From this record, which is mainly recorded in the "water irrigation of Jinyang", it shows that if the enemy does not regain effective control of the army after the water attack, and then launch a fierce attack, then it will be a catastrophe for the enemy.

It's just that Jinyang, who was flooded first, did not suffer a subsequent attack, if this situation is extrapolated to Yancheng, then Bai Qi will not choose this way to directly attack Yancheng, but wait for the defenders of Yancheng to become weakened, and then choose to launch an attack.

And at this point, it seems that it can be deduced that Wang Ben attacked Daliang City, and it is very likely that he will choose this way, because when the King of Wei was fake, he finally chose to surrender out of the city, and it is very likely that the situation in Daliang City at that time has become unable to continue to hold on.
