After a short period of repair, the natives began to attack, at least 4,000 people pressed up, divided into four directions, almost 1,000 people in each direction, and rushed up in all directions, without giving the navy a chance to break through.

The current settlement is a base with a building as the center and a wall of at least more than 1,000 meters long, and the total area is about 100 acres.

Settlements are not good at this, the area and circumference are too large, unlike the bastion.

The purpose of the fortress is to be used in the war, and in the war, how to use the best ratio to achieve the artistic effect of killing, this is the consideration of the fortress.

Its appearance changed the characteristics of defense, so that many things in the art of war have changed, and before there is no civil strife, or artillery, the possibility of capturing the fortress by manpower alone is very low.

Small is a key feature of the fortress, the small of the fortress, different from the previous large defense system of the large, although the larger defense system, can accommodate more troops, but the fortress in the small at the same time, pay more attention to the effectiveness ratio.

After a unique design, the fortress has achieved the ultimate in every part of the defense, ensuring that the fortress invests more troops in every direction than the attackers.

The strategy of the cold weapon era, the strength of the soldiers, is only a characteristic, the key is the efficiency of use, one side can play 120% of the effect, the other side can only play 30% of the effect, as long as it is not a huge difference, victory must belong to the former.

The same is true of the military formation, some unique military formations, that is, to let the same direction, the greatest possible face of the enemy, the same is true of the fortress, itself climbs upwards to attack, it is on the weak side, now there is an increase in the contact surface, a siege of the city, to face 3, 4, or even more enemy attacks, such a defensive strength has obviously risen.

Even if there are more troops, there are only so many troops invested in the fortress, and the advantage of troops cannot be brought into play at all, and in the face of the fortress, you can only use the tactic of adding oil, which is actually the source of the terrible fortress.

The purpose of the building is completely opposite to the fortress, the purpose of the building is to accommodate more people, so that these people can live in it, compared to the fortress, it is too spacious.

Spacious means wide circumference, and it means that there are more people who need to be armed.

Similarly, the height of the building is higher than that of all the walls of the Northern Song Dynasty in this era, but compared to the fortress, it is still much worse.

The natives who returned reported some information, and these natives carried some tools for climbing, not smooth, but numerous windows, just buildings sealed with iron bars, more or less, easy to climb.

The only person in Sun Yue's hands who has the ability to kill is still the longbowman, but unfortunately, the number of longbowmen is not large, that is, more than 200 people, in the middle, it is necessary to transfer enough personnel responsible for the front line of defense, because of the relationship between the many opponents, it is impossible to end the battle in a short time, and the longbowmen also take the fight.

When the natives were rushing towards the settlement, the longbow was also within range and began to attack, and in a short time, the longbowman who burst out with 200 rounds of shooting, basically completed 15-20 rounds of shooting, and took a short break to ensure continuous combat capability.

How many arrows can be shot in this way, under the premise that the attack camp of the natives is obviously loose, the lethality is even more insufficient.

Several rounds of confrontation, a full morning, more than 2 hours, most of the natives approached the outer courtyard wall, the casualties were not large, more than 2 hours, the longbowmen basically completed about 180 rounds of shooting, more than 50,000 arrows, and achieved almost more than 800 results.

The casualty figure of more than 800 may be a huge number for two or three thousand people, but for a team of 14,000 people, it is not very high.

The existence of the courtyard wall helped the settlement to stabilize the perimeter, but it brought some inconvenience during the war, that is, the natives could hide there, and the tall courtyard wall, when hiding underneath, made the archers have no shooting range.

Of course, Sun Yue had considered this issue before, but in the end, he still let the courtyard wall exist, because he was also a barrier, especially when there were no enemies.

The courtyard wall has a strong defensive effect on any number of enemies, and with the presence of the courtyard wall, you don't have to worry about someone infiltrating the camp, and the defense task will be easier.

Similarly, the courtyard wall has such shortcomings in battle, but the courtyard wall is not so easy to break, and the structure of masonry and cement is basically equivalent to stone, which is not easy to deal with for the natives who do not have steel tools.

Even if the courtyard wall is breached, the several layers of barbed wire inside are not easy for the natives to cross.

The attack of the natives, under the courtyard wall, has stopped, and they seem to have made a plan, when a large number of natives arrived on the side of the courtyard wall, they did not continue to attack, they just hid there and recovered their strength.

Probably after a stick of incense, there was a sound of impact, as if holding a tree and striking the courtyard wall.

This is probably the only existence of the natives who can attack the courtyard wall, maybe it was the previous person who went back to report that when they arrived, the aliens had burned the trees, maybe the trees were the nemesis of these things, and when they came here, they also carried a lot of giant trees.

In the mountains and forests, with huge logs, running so far is really a burden, I thought that these logs could easily break through this wall, but I didn't expect that it didn't have much effect.

When the sound of knocking sounded, Sun Yue was worried, this is just a wall, in case it is impacted and it really collapses, it will also be a little sad.

The combat effectiveness of the fortress has been tested by war and siege equipment, but the wall is gone.

Dingjun is a new city, in the past time, it was too late to build crazy, and no one would casually smash the wall to play, and they didn't know the intensity.

But with the attack of the natives, Sun Yue put his mind at ease, the sound of knocking and knocking kept ringing, and the courtyard wall was not broken for a long time.

Sun Yue knew early that the natives would attack, but 14,000 people came at once, which was a little unexpected, and the only thing he was fortunate about was that the opponent's combat effectiveness was very weak.

For soldiers who are not sufficiently armed and untrained, they can only be called militia, and even the standards of the navy cannot be called militia.

The natives are not stupid, the previous tribe, the loss is so huge, it has awakened many people, this time, they used the method of water milling, and gradually besieged here.

It can't be said that their method is wrong, but too much time has been wasted before, in fact, 29 days have passed since the siege of 14,000 people.

If there were only a few hundred people in the settlements of the navy, their approach might work.

14,000 people, gathered together, if they move forward steadily, they don't seek merit, but on the premise of seeking no fault, it is really not easy to defeat them.

Even if you have suffered a certain amount of losses, as long as you are smarter, no longer greedy for merit, and besieged around, the navy will still be able to attack it.

The strength in Sun Yue's hands is limited, unless it is through siege warfare, which greatly consumes the opponent's strength, otherwise, there is no way to counterattack.

Sun Yue's idea is to use a wave of remote consumption, that is, through the courtyard wall, barbed wire, and buildings, continuous consumption, consumption to a certain extent, is the time for the counterattack to come.

However, the first wave of courtyard walls blocked the enemy's footsteps, which was unexpected.

This is a courtyard wall, not a city wall, and the Dinghai Navy has not spent a lot of energy, not a simple single-sided brick wall recently, but a slightly thicker double-sided wall.

The surface of the red bricks is relatively neat, and the overall height is about 3 meters, and the natives have never seen such a wall, so there is no relationship between climbing, and they can only use wood to hit.

An ordinary wall is a little too thin, and it can't last long under the impact of giant trees, but this is a little different from ordinary brick walls, that is, the effect of cement binder.

The reason why cement has become an important military material is because of its adhesive properties.

The strength of the bricks themselves is still different from the rocks, and most of the cities in the Northern Song Dynasty had tall city walls, and in the face of attacks such as catapults, the stones were easy to smash those bricks.

With the addition of cement, it is different, because of the relationship between cement bonding, as long as the cement surface is not damaged, or there is a problem, the whole is a whole, in the face of the impact of a certain place, it will disperse various forces, obviously the wood hit an area, but it is indeed the surrounding force, such a whole, of course, is not easy to be breached.

This is not a tough, high-grade cement dam, just an ordinary brick wall, the cement used is not too much, just a layer of coating on the outside, which increases the strength and is limited, especially in the continuous impact, when the strength of the impact exceeds the bearing capacity of the entire wall, the wall will definitely collapse.

In the process of impact, there was a problem, there were too many natives gathered on one wall, and in the process of impact, that wall collapsed.

The wall is a four-story brick, plus the height, a height of more than 3 meters, the weight of the bricks plus the cement, the weight itself is not small, through the impact of the giant wood, resulting in a large area of collapse, almost more than 40 meters long a section of the wall has fallen.

The defensive effect of the high wall on the longbow, until now, the damage suffered by the natives is mainly caused by these longbows, even now, they have completely surrounded the settlement, but as long as they show their heads a little and are detected from above, they will be hit by the longbow, in order to avoid increased casualties, they all hide under the wall.

If you change to the wooden or earthen walls in the stockade, these people will not choose this way, and it will easily collapse.

This wall can withstand the impact of the giant tree, but I didn't expect that this bearing is amplitude, and under the premise of reaching a certain degree, the giant wood is vibrating and impacting, because the wall is a whole, and the overall force is strong, once the critical point is exceeded, at least, a large area will have problems.

The collapse of the wall of more than 40 meters is still under the premise of gathering a large number of people, and the bricks and cement poured things, as long as four or five bricks are mixed with cement, they have a lot of lethality, not to mention a larger, broken wall, the whole piece of collapse, immediately wail.

Not to mention that the natives didn't think of this situation, even Sun Yue, the initiator, didn't think that the role of the wall was just to enclose the land and prevent wild animals from coming in.

The building is large enough, the circumference is more than 600 meters, so that the small number of troops of the Ding Navy is stretched, the wall is outside the building, and it is fully extended outward by 100 meters, that is to say, the circumference is more than 1000 meters, it is still relatively weak, it is not easy to take care of the whole, and the strength of the Ding Navy of more than 500 is not able to take care of such a wide range at all.

The city is not as big as possible, but depends on the strength of the defense, similar to Bianliang, such a huge city, but only when the Northern Song Dynasty was prosperous, it can be supported, and then once it declines, Bianliang, which is located on the bank of the Yellow River, has no danger to defend at all.

On the contrary, it is Chang'an, Luoyang, and Beijing, the imperial capital of the ages, and Beijing in later generations, they are easier to guard, there are a large number of checkpoints and supports, even if they lose one or two, as long as there are support points, there is no problem.

Similar to Bianliang, once the Yellow River is broken, there is no danger to defend, and the Yellow River is also relatively dangerous.

Not to mention that the Yellow River will freeze in winter, when the time comes, fast horses can gallop through, even in the dry season of spring and autumn, in some more suitable places, you can also force crossing, more than a hundred years later, Jingkang's shame, Jin Guo is after crossing the Yellow River, only to threaten Bianliang.

The circumference of 1000 meters seems to be only about 400 meters longer than 600 meters, but the area to be protected, the internal rotation, and the defense in all aspects have changed dramatically, so that Sun Yue is destined not to invest too many troops on the city wall, and even some proper arrangements have not been carried out, allowing the natives to attack and use.

No one thought that such a simple protective wall would actually play a great role in the battle and produce unexpected joy.

Simple casualties are nothing to the natives, but they don't know about these city walls, they think they can't hit them, they crashed for so long before they collapsed, and they collapsed and smashed so many people, such a long city wall, it is impossible to smash them all, but the effect of smashing down this section is very high.

The wall is more than 40 meters long, and there are about 500 people around it, plus those who are attacking the city with huge logs, at least 200 people are smashed under the wall, with many dead and wounded, and the howl is non-stop.
