"Well, what Yang Bingma said is very reasonable, and Ben Shuai agreed! This is together with the Yang soldiers and horses, leading the generals to patrol the city, if the Yang soldiers and horses have any suggestions, please say it, and a certain will obey the arrangements of the Yang soldiers and horses!"

Ge Shuhan's answer made Yang Xi feel relieved again! This old handsome man is really very cooperative with himself!

Although he didn't fully know what the specific reason for Ge Shuhan to make such a change in just half a day was, Yang Xi believed that focusing on the overall situation must be a very important reason. When he arrived, he expressed a kind of fairness and fairness, and proved it with practical actions, if Ge Shuhan, a defeated general, at such a time, still hold on to personal grievances and ignore the overall situation, it would be too much to say.

The speed was also very fast at the very moment, and in a short time, all the generals who received the order gathered in front of Geshuhan's tent.

Sometimes, instead of gathering at the head of the city, the gathering of the people will set out together, just to create momentum, to create a terrifying momentum!

Seeing that all the generals had arrived, Yang Xi saluted Ge Shuhan and said: "Marshal Ge Shu, in order to boost the morale of the soldiers, the last general will accompany the marshal to inspect the city and comfort the army!"

Ge Shuhan replied with a salute, and then shouted to the generals: "All the generals have an order, and they will patrol the city with Ben Shuai and Yang Bing and Ma Envoy!"

As he spoke, he took the lead in walking in the direction of his war horse with inconvenient feet, and several personal soldiers hurriedly stepped forward and helped Ge Shuhan to get on the horse. Yang Xi also hurriedly followed, and the generals silently followed behind according to the level of their positions.

The tour of the city starts from the east gate, and then extends in the order of southeast, northwest, and northwest!

After receiving the order, all the soldiers gathered at the city gate and stood by, ready to be reviewed by the generals!

It was a very hot day, and in order to lose morale unnecessarily, all the soldiers lined up at the position where the sun was shining near the city gate.

At this time, it was past noon, the sun was leaning westward, and a large shade appeared in front of the city gate tower, which also brought a little convenience to the defending sergeants, and when there was no situation, even the sergeants guarding the city could hide in the shade under the city gate tower.

A group of generals rode tall horses, patrolled the gates in a neat procession, and shouted to the sergeants leading the procession, telling them that our army would definitely be able to hold Tongguan in this battle and defeat the rebels.

The generals who led the army had such an imposing performance, and the morale of the sergeants must have been encouraged to a certain extent.

And Yang Xi also took the opportunity to familiarize himself with the terrain in the direction of each city gate, especially the fire has not yet burned out, but the situation in the direction of the south gate of the forbidden ditch has reappeared, and he also has a further understanding.

The forbidden ditch is actually a trench valley-like landform belt, with Yang Xi estimating that the depth is about five to thirty meters, the width is about ten to fifty meters, it is not far from the southeast direction of Tongguan City, the total length is dozens of miles, and the nearest place is attached to the south gate.

If there were no drawbridges to connect with the road outside the forbidden ditch, it would be difficult for even apes to climb over.

To the west of the forbidden ditch, there are twelve cities, that is, twenty small beacon towers, guarding the forbidden ditch, and the forbidden ditch and the twelve cities jointly defend Tongguan City. It's a pity that there were too many soldiers of the Tang Army who fled and returned, and they actually filled up a section of the forbidden ditch, so that the forbidden ditch became a thoroughfare.

The guards of the twelve cities on the side of the forbidden ditch that had become the passage also fled or were removed by Geshuhan.

The twelve cities are only twelve small beacons, each city can only be equipped with a hundred soldiers, if the forbidden ditch is in danger, more than a hundred sergeants are guarded according to the forbidden ditch, and the ability to block the enemy's attacks is very strong, but if the forbidden ditch guards are filled with corpses, the role of hundreds of sergeants on the beacon tower will be greatly reduced, so Ge Shuhan fled back to the city, collected the rout, and withdrew most of the sergeants on the twelve cities.

There were originally many shrubs growing in the forbidden ditch, and the original forbidden ditch landform can still be seen in the section where there is no corpse accumulation or the corpse is not completely blocked, but this forbidden ditch under the south gate can be filled with corpses. Early in the morning, Ge Shuhan ordered oil to be burned, but so many corpses were piled up, it was impossible to burn them all, the fire burned for half a day, and only nearly half of the corpses were burned, and the ones that were piled up below could not be burned again, unless someone entered the ditch, removed the ashes and charcoal on it, and then burned with oil and hay, then it was possible to continue burning.

But now it is impossible to send a sergeant down to clean up, the temperature is too high, and people will be scalded to death.

However, the forbidden ditch that has been burned has initially restored its essence of the moat, and has a certain function of resisting the enemy, at least it is impossible for the rebels to step on the corpses in the forbidden ditch to attack the city of Tongguan.

"Marshal Geshu, the last general thinks that the twelve cities should not be abandoned, and should be re-sent to defend them, there are twelve cities guarding the forbidden ditch, and the rebels will have to pay ten times the casualties if they want to attack the city of Tongguan!" After carefully observing the terrain in the direction of the south gate, Yang Xi said to Ge Shuhan very solemnly: "The forbidden ditch natural danger has been cleared out of a sufficient depth, and with a certain degree of ability to resist the enemy, if the Twelve Cities give up like this, it is equivalent to giving up half of the natural risk advantage of Tongguan City!"

In fact, Yang Xi couldn't understand it a little, Ge Shuhan, such an important defense facility in the Twelve Cities, actually gave up, and the Hantong Guancheng, which was connected to the Twelve Cities, also gave up, what did Ge Shuhan think? If you want to defend Tongguan City, these places must be defended!

The natural danger of Tongguan does not only refer to the height of the city pass, easy to defend and difficult to attack, but refers to the combination of the city pass and the surrounding terrain to form an incomparably strong defensive fortress, the rebels come from the east of Tongguan, if you want to break through Tongguan City, you must overcome the disadvantages brought by the steep terrain, and then capture Tongguan City after the defensive position on the periphery of Tongguan is captured.

If the troops are deployed in the Hantong Pass City and the Twelve Liancheng, then the rebels must first break through the Hantong Pass City, and then pull out the Twelve Liancheng, and cross the forbidden ditch to attack the outside of Tongguan City, and only then can they have the opportunity to attack the gates of Tongguan. There are not many troops that can be deployed in Hantong Pass, and the same is true for the Twelve Liancheng, but to break through these key passes, the efforts and costs paid by the rebels must be very large.

When Yang Xi arrived at Tongguan and made the initial deployment, he only listened to others talk about the terrain and various dangerous places in Tongguan City, but did not actually observe these places, so it can be said that he did not have a very specific concept. After assigning the task, he only observed the situation in the direction of the east gate, and did not look closely at the other directions, which was a mistake on his part, mainly because he was afraid that the rebels would attack the city immediately. During this tour of the city, after a careful look, I became clear about the terrain in all directions, and I also had some deeper thoughts about the initial military deployment, that is, the twelve cities must be garrisoned again.

If 2,000 troops are deployed in the Hantong Pass, the rebels will have to attack the Hantong Pass at least with about ten times the number of troops, and if the Hantong Pass is to be broken through, the defenders above will be completely annihilated, at least several times the price of the troops.

Each pass of the Twelve Cities can only hold a hundred soldiers, but if you want to occupy each pass, you will have to pay more than ten times the price.

These places can not only be used as a prominent defensive unit of Tongguan City, but also can effectively block the rebels, delay the rebels' attack on Tongguan City, and effectively kill and injure the rebels.

At the cost of hundreds of people, how can it not be such a cost-effective thing to destroy hundreds or even thousands of rebels?
