Why did the ancients build the moat, is it just as simple as defense?

The moat is also known as ".Hao"Its main role is to defend against foreign enemies, block the entry of some animals, of course, it is also used for agriculture, drought prevention and control, and water storage.

In the ancient siege means, fire attack is a more common siege means, then the moat will reflect its strong "self-rescue" function, the moat in the sufficient water source, can play a good role in fire attack. In the face of flood disasters, the moat also plays a good role in dredging water sources, most of the water in the city will be discharged into the moat, and the larger water conservancy project also plays a certain role in transporting while defending the city.

Moats and walls, cities together form a "city". Most of the moats are built according to natural natural convenience, and a certain amount of artificial construction, and its most spectacular moats are to be"Xiangyang Moat" and "Forbidden City Moat"!

Xiangyang Moat: Known as "the first city in China". Xiangyang in our impression, this is Jin Yong's martial arts ** in Guo Jing's hero to resist foreign enemies, is an important line of defense of the Song Dynasty, according to historical records, as early as the Song Dynasty when its average width has exceeded 180 meters, the widest place will even reach 250 meters!

Moat of the Forbidden City: The Forbidden City has always existed as our "imperial capital" during the Ming and Qing dynasties, and it is the "heart" of our ChinaTherefore, the construction of its moat can not be so-so, the Forbidden City moat was built in the Ming Dynasty in the eighteenth year of Yongle, according to the data, the total length of the Forbidden City moat is about one kilometer, the river width is about 50 meters, the circumference is 3,240 meters, and its average water storage has reached 542,880 cubic meters!

We have to admire the wisdom of our predecessors, these projects are a big problem in the modern era when industrial development is so advanced, and in that era when industrial development is so backward, they can complete such a great project, we have to feel sincere admiration.

The reason why the ancients built moats was not only for defense, but also for agriculture and water storage.

Moats serve many purposes, on the one hand, they can defend against the invasion of foreign enemies, and secondly, they are part of a city's drainage system and help the city recycle water.

I think it's not just that simple, of course, defense is the most important reason, and I think the reason is that it is easy to get water on the spot, and if there is a fire, it is easy to prevent it.

On the one hand, the ancient people built the moat for defense, and on the other hand, the moat can also provide water in the event of a fire or other emergency need to solve the urgent need.

In fact, the biggest role of repairing the moat is defense, but there must be other functions! For example, if you build a long moat, you can show the strength of the country.

No, it's not just defense, in ancient times, houses were basically wooden structures, which were easy to catch fire, and the moat was also built so that there was a water source to extinguish the fire when it caught fire.

In ancient times, people built moats to defend against the enemy, if the enemy was going to attack, it would take a little time to build bridges and the like, and it was also more effective in protecting the people in the city, and the moat, he also had a role in water transportation.

Repairing the moat can not only defend the field, defend the country, and prevent the enemy's fire attack, but also meet the water supply in the city, even if there is a fire in the city, it can also transport water in time.

The main purpose is defense, but it can also be used to extinguish fires when walking water, or to facilitate transportation, anyway, it has multiple functions in one.

In addition to defending against enemies and maintaining security in the city, it can also be used for transportation; It can also provide water for the city to fight fires or farm farming.

Chengchi is a unique special military and civilian facility invented by the ancients in China, integrating military, political and cultural aspects. The city is actually two words, the city is the city and the city wall, and the pool is the pool, the moat, many places, especially in the north, due to the lack of water to dig a ditch, this kind of no water is called a moat.

The moat has the function of self-rescue, not only can prevent the enemy's fire attack, but also can meet the needs of the city's water, and is an important water conservancy project for flood control and drainage, some are close to the river can also assume the function of transportation, the moat is not only for military purposes. The soil from digging the moat can burn bricks and fill the soil and repair the city wall, so that even the freight is saved, and the cost of repairing the city wall is greatly saved.

A moat, also known as a moat or castle, is a river dug by hand in ancient times that surrounds the entire castle, the palace castle, the temple and other major buildings, and has a defensive effect to prevent the invasion of enemies or animals.

Countries around the world have dug moats in ancient times. Moats were built in places such as the Forbidden City in Chinese mainland Beijing, the ancient city of Hsinchu in Taiwan, the old city of Zuoying, the city of Yizai Jincheng, the ancient cities of Japan such as Matsumoto Castle, the Imperial Palace in Edo (present-day Tokyo), and castles and imperial palaces in various European countries. Many castles in Europe had wooden bridges over moats that could be raised to facilitate access and to prevent enemies from entering.

The predecessor of the moat is the moat, and the tradition of building a city in China is to build a city in a place near the mountains and rivers, so the moat soon became a moat, and its role is also very large: in peacetime, it can be used as a firefight, and it can also control the number of passages in and out of the city (the height of the wall of most cities in ancient times is not as high as we think, and it is easier to have a river as a limit in terms of defense), in wartime, the moat is mainly used for two purposes, one is to prevent the enemy's siege equipment from approaching the city wall, and second, as mentioned above, reducing the possibility of enemy soldiers approaching the city walls, forcing the enemy to choose only a few places to siege the city. Therefore, in the siege war, the first thing the attacker did was to fill in the moat and draw out the water in the moat, the distance between the moat and the city wall was not determined by the distance between the bow and arrow, you must know that the moat was too close to the city wall, it would erode the foundation of the city wall, and the real construction should consider the factors of the siege equipment and geographical factors at that time, but the moat is another matter.

In addition, there are few cases of using shields to top the enemy's formation in Chinese wars, this is due to the difference in Chinese and Western perceptions of war, the infantry in Chinese wars are basically lightly armed, and the formation is far less dense than that of Rome or Greece, and there is no Roman style of raising the shield into an impermeable iron back or a formation to top the enemy (it was not until the Han Dynasty that China saw the Roman-style phalanx for the first time in the Western Regions). A little bit of a study of the Chinese formation is Japanese cinema, if you go to see Heaven and Earth, you will understand.

The main thing is its defensive role.

In ancient times, it was the age of cold weapons, there were no guns and the like, and the best bows and crossbows generally had an effective range of 1,800 steps. Therefore, there is a protective wall, and the moat plays a very strong defensive role. Most of the walls are defended, such as rolling wood thunder stones.

Moreover, the castle tower is also used as a powerful tool to transmit signals, and the water of the moat is still the domestic water of the residents in the city, so most of the water in the moat is living water, which is also the reason why most of the ancient big cities were formed by the main rivers. For example, in ancient times, there were many examples of besieging cities and winning without cutting off their water sources.

It also facilitates transportation and strengthens defense capabilities.

The most effective way is to break the city from a distance first, and after suppressing the opponent, send infantry to fill the sandbags!

It is not allowed to use corpses as siege props on the regular battlefield! Filling rivers with soil is the most common method. Because it is impossible to have corpses fill the river for you before crossing the river, why not let them stand there and let the enemy shoot them first, and then let the people behind them use them as materials for filling the river?

Therefore, when attacking the city, sandbags are the best way to cross the river!

First: the loss of flexible flashing with a ladder across the river, and the concentration of people, is the best live target for enemy archers!

Second: there can't be too many materials to help build the tools to cross the river before the siege, and the most convenient thing that can be easily obtained in land battles there is dirt!

Third: The sandbag thing is worthless, the cost is low, it doesn't take time, and everyone will!

The answer is – sandbags made of dirt!

The long ladder fell down and set up on the river, crossed the river, and ascended to the city. But the bloody ones were filled in a few ways by the corpses in a while.

The ladder can't be used as an airplane.

A moat, also known as a moat, is defined as a river dug by hand around a city wall. In ancient times, the moat was mainly used for defense, maintaining the safety of the city, and facilitating transportation.

In ancient times, almost many cities would have built moats, so what was the purpose of moats? Let's talk about what the ancient moat did.

The moat, also known as Hao, is defined as a river dug by hand around the city wall, which was used for defense in ancient times, and was a river dug by hand in ancient times to surround the entire city, the imperial palace, the temple and other major buildings. Moats have been dug in ancient times around the world, such as the Forbidden City in Beijing, the Ming City Wall in Xi'an, the Ming City Wall in Nanjing, the Moat in Jinan (Jinan Huancheng Park), the Moat in Xiangyang, the Ancient City of Hsinchu in Taiwan, the Old City of Zuoying, the Golden City of Yizai, the ancient cities of Japan such as Matsumoto Castle, the Imperial Palace in Edo (now Tokyo), and the castles and imperial palaces of various European countries.

In ancient times, the moat was mainly used for defense, maintaining the safety of the city, and facilitating transportation.

The moat in the world is the widest with the width of the moat in Xiangyang. According to historical records, as early as the Song Dynasty, its average width exceeded 180 meters, and the widest point reached more than 250 meters, which can be called the first city in China.

The Forbidden City Moat, the moat that surrounds the perimeter of the Forbidden City, was built in the 18th year of Yongle in the Ming Dynasty (1420). The river is 52m wide, with a stone revetment built on the ground, which is solid and steep, and is also known as the tube river. The river flows from the northwest and flows southeast to the Imperial River.

In the Qing Dynasty, the lotus root was planted in the river, and the annual harvest was used in the palace, and the rest was sold, and the silver was stored in Fengchen Garden for later use. The moat is 580 years old. In 1999, the moat was treated, the revetment was renovated, and the bottom of the river was paved with square bricks, making the river more solid.
