This method is very safe, as long as Gu'an City is not lost, as a guard, there is no responsibility. If you can drag the enemy under the city and wait for reinforcements, with the speed of the Liao cavalry, they will surround after dawn, and it is a great achievement to encircle and annihilate the enemy inside and outside.

In any case, holding on to the situation of waiting for help is a good way to ensure a bumper harvest in drought and flood, and there is no problem in the case of not knowing whether we are friends or enemies. But sometimes you can't seek stability on the battlefield, and the reason why a general can lead a side is that you have stronger judgment than others and can always choose the right way.

The current Khitan generals are far from being the fierce generals of the early days of the founding of the People's Republic of China, and their comfortable living conditions and desire for power have worn out their desire to fight, and they tend to be more infallible in their thinking.

At first, Hong Tao couldn't believe that the defenders of Gu'an had given up the Wudinghe Bridge, for fear that it would be a trap, and he prepared to storm Gu'an according to the original plan, and after taking the city, he also controlled the bridge.

But Wang Qi went with the special forces and the new army for a while, and then sent someone back to report the news, and the bridge changed hands. He not only occupied the bridgehead on the south bank, but also advanced to the north bank, digging trenches and arranging defensive positions.

That's still a fart, there is only one purpose for storming Gu'an: so that the troops can successfully cross the Wuding River. Now that the bridge is occupied by Wang Qi, and the defenders of Gu'an have no signs of coming out to meet the battle, don't wait, slip away!

But 30,000 people and nearly 1,000 box trucks can cross the river by a bridge for the fastest hour, and the defenders of Gu'an cannot be idle during this time, and they must be kept busy so that they will not be blind.

So the offensive of the new army was launched, with the west gate being the focus of the attack and the north gate being the response. In fact, the siege troops in the west were moving towards the bridge little by little under the cover of night, leaving only six battalions and five siege crossbows, and from time to time throwing two thunderbolts on the city.

Ammonium oil is indeed more powerful than black powder, especially against ancient brick and concrete buildings, no need to dig a hole to bury and detonate, just by the earthquake has already cracked the west gate several big openings, and the city tower is also crumbling.

"Don't stop, concentrate on bombarding the tower!" Wang Da got the order to feint to create momentum, she understood the boss's intention very well, feints are also attacks, and it is necessary to create momentum.

The soldiers of the new army could rush to the moat and retreat under the howl of arrows, but they could not put no pressure at all, and if they could blow up the tower, the momentum would be almost enough, and the defenders of the city would be busy for a while.

The general's intentions are also well understood by the soldiers, if you want to blow up the city tower, then don't throw it on the city. The thunderbolt is round, and the explosion time is very difficult to grasp, and if you throw it, it may not explode, and if it is exploded, it will not necessarily be on the castle tower.

Just throw it into the city gate hole, the limited space can increase the destructive power, and the city tower will collapse as soon as the city gate hole collapses. The three thunderbolts fell in response to the sound, or fell inward, and it is not clear how many defenders were killed, and the smoke raised could not even see the moat.

"Pack up your equipment and leave!" Wang Da looked at the hourglass and felt that the time was about the same, and gave the order to retreat. More than 2,000 new troops did not even dismantle the siege crossbows, and ran away as soon as they put them on the box cart.

Compared with the West Gate, Hong Tao's attack at the North Gate was much more lively, as soon as he came up, he was blown up by the sappers who dug a pit and buried the ammonium oil roll under the rain of arrows to blow up the moat bank, and then laid a wooden plank to push the box car to force the moat, and stuffed the ammonium oil medicine roll into the city gate hole in the face of rolling wood and stones. After a loud bang, the city gate tower and more than ten meters of the city wall collapsed.

At this time, the heavy armored commandos of the new army came on the field, covered with steel armor from top to bottom, and holding half-body shields and short swords in their hands, row after row, looking terrifying. But this pomp and circumstance was a bit slow, and the queue alone lasted three quarters of an hour, and then moved step by step to the moat to receive the baptism of arrow rain.

Bows and arrows were of little use to the tin men, but the hoplites had a hard time climbing the ruins of the walls. After tossing for a while, Wang Dadu came over, and the iron-skinned men here were still lined up by the moat.

"It's done, let the warriors come back, this is useless."

The Tin Man and the Half-Body Shield are both new classes designed by Hong Tao on a whim, equipped with only one battalion and no tactics. Originally, he wanted to give Zhao Maid to support the façade, but as a result, the six princes got on the sea boat, and these arrangements became redundant.

"Cross the bridge, don't play with them anymore!" Don't look at the hard work of the tin man, he ran very fast when he retreated. It's cost-effective that they just pretended, just to delay time.

The defenders of the city suddenly found that the enemy had withdrawn, and they did not dare to attack rashly after enduring it for a long time, for fear of being ambushed, and the enemy's giant crossbows and weapons that could make loud noises were too powerful. It wasn't until a louder noise broke out in the north of the bridge that the defending generals suddenly realized that they hurriedly arranged for the cavalry to pursue.

At this time, another problem was discovered, the north gate and the west gate were blown down, and the east gate was a swamp to the north, and it was more than ten miles to go around, and it was only possible to start from the south gate.

At this time, the Gu'an garrison has figured it out, no wonder the enemy wants to attack from the north gate and the west gate, and the two city gates have been blown down, which is premeditated.

In fact, he spends the belly of a gentleman with the heart of a villain, Hong Tao really didn't arrange it like this, he just had nothing to do and sabotage. Before the new army was finished, the bridge deck on the north side was loaded with ammonium oil rolls by sappers. There are no fear of how many pursuers there are, the more they come, the better, and they all have to go to the Wuding River to take a cold shower.

Wuding River is the Yongding River of later generations, at this time it is one of the largest rivers in Hebei, wide and deep, the water flow is turbulent, rolling to the east, and the top of the two Baigou River. Without this bridge, the Liao army would have to make a detour of more than 100 miles to cross the river from the bridges upstream and downstream.

However, Hong Tao did not damage the piers of the bridge, and only blew the bridge deck about 10 meters. If the new army has to retreat south from here in the future, relying on the ability of the engineering troops to build bridges, it will be able to fill the gap in one or two hours, which can be regarded as leaving a way for itself to retreat.

This is the advantage of having an accurate map, but it is a pity that the Inspectorate of Mountains and Rivers has not been established for many years, and it is powerless to do anything about the topography and landforms further north of the Setsu Prefecture. However, even if there is a map, Hong Tao doesn't want to go further north, and if he takes back Xijin Mansion, he will master the Yanshan moat, and he will operate well all over the walled fort for a few years, and it is easy to have an advantage in the confrontation with the Liao State, and it is meaningless to expand northward.

The terrain and climate over there are not suitable for the development of agricultural peoples at all, and it costs a lot of money to grab it back and then throw it away just to say it and listen to it? Isn't that sick?

If Emperor Shenzong could still trust himself, it would be the right thing to take the new army back and kill the Western Xia first. Don't look at it, it only has a small part of the country left, but it is a variable to keep it after all.

Only the Song and Liao countries were left to live in peace, and according to the scale of economic development of the Northern Song Dynasty, the longer it dragged on, the more unfavorable it would be for Liao. There is no need to make a big move, just fund the Bohai people and obstruct the divination people to cause civil unrest in Liao, and you can take advantage of his illness to kill him.

"Ah Su Death Force, let your people divide into several groups to report to the front, just say that the Youzhou Han soldiers in Xincheng rebelled, burned forage and the Wuding River Bridge, attacked Gu'an and retreated to Yongqing without success, and have been intercepted and defeated by your Bohai soldiers. Most of the Youzhou Han soldiers were killed in battle, and a small number were fleeing to the Baigou River. ”

Now Hong Tao doesn't have time to think too far, Xijin Mansion is seventy miles away, and if nothing else, he will arrive at dawn. According to the information of the Shanchuan Inspectorate, there are not many garrisons on the north bank of the Wuding River, and there are many farmers who cultivate, and there are only more than 20,000 Pi Room troops and Youzhou Han soldiers near Xijin Mansion.

But how can you avoid surprises when plans can't keep up with changes? That is to add confusion to the enemy, so that their brains are turned into a pot of porridge by all kinds of contradictory information, and the more hesitant, forward-looking, and suspicious, the less trouble the new army will have.

It is okay for the Bohai soldiers to fight, but it is the most suitable to be a false letter. These people from the deep mountains and old forests are known for their sincerity in treating people, and who would have thought that they would suddenly meet a true god. Not to mention that honest people are the most terrible to learn badly, and they can deceive people into being stunned.

After the hour, the sky cleared a little, but the moon was still invisible, and it hid behind the clouds in shame. However, something is better than nothing, and by the faint moonlight, both sides of the post road are full of harvested farmland, and there is no edge in sight. After walking for two quarters of an hour, it was as if there was no place to move, and the scenery remained the same.

"This place is not worse than the Daimyo's Mansion, and with a little management, it is the land of fish and rice!" The further he went, the closer he got to his hometown, even though Hong Tao understood that the Xijin Mansion at this time had little to do with Beijing in later generations, and even the location was not the same, he still couldn't help but feel a little emotional.
