To arrange the defense of the concession, Major Bower did spend a lot of effort. In view of the large area of the concession and the insufficient number of guards in the concession, Major Bauer first decided to shrink the defensive line, giving up the concessions of the United States and Germany, and instead concentrating his troops to guard the British and French concessions, so that more than one-third of the defense area could be reduced. As a result, the difficulty of insufficient guards in the concession was greatly alleviated.

However, the concession has no city walls, and it is too late to build fortifications now, so it can only be divided into two defensive cores with the British Concession defense area and the French Concession defense area, and some simple fortifications can be put together with stones, sandbags, wooden boxes and other materials at several important intersections, and then the houses and buildings on the periphery of the concession can be used to resist the attack of the crossing army. The buildings in the concession are all brick and stone structures, most of which are two- and three-story buildings, and they have a certain resistance to small and medium-sized artillery. It's just that there is no artillery in the concession, only four Maxim machine guns.

Colonel Bauer also ordered that the inhabitants of the area of about 200 meters after the order line were basically emptied, firstly, the vacant houses could be used for fortifications, and secondly, in order to reduce the casualties of ordinary people.

Therefore, at eight o'clock in the morning, a fortification was built on the periphery of the concession, which was considered a defensive line, but whether it could withstand the attack of the enemy army was not even known to Colonel Bauer, although he boasted in front of the consuls of various countries that he could hold the sea for three days.

In fact, when waiting for the attack time, Qin Yuhai was not idle, on the one hand, he sent drones to the sky above the concession to check the traffic and road conditions of the concession and understand the defensive layout of the concession, and on the other hand, he also recruited the company commanders to discuss the tactics of attacking the concession.

This attack on the concession was during the day, so the superior night combat capability of the crossing army could not be brought into play, which invisibly greatly weakened the advantage of the crossing army, and strategic weapons such as helicopters could not be easily used.

However, the layout of the Tianjin concession is closer to the urban layout of later generations, so this battle is also a typical urban battle, and this battle mode is exactly what the soldiers are best at. This is because in the old time and space, the probability of a large-scale ground war was extremely low, and most of the wars between countries in modern times are high-tech, high-tech, information-based, and even air-space integration.

Ground warfare, which involves infantry in ground warfare, is mostly carried out in the form of anti-terrorism and anti-riot, and most of them occur in cities or mountainous areas, so the training of urban warfare accounts for a large proportion of modern infantry training, and most of the infantry's individual weapons are also adapted to this style of warfare. Such as stockless design rifles, gun-mounted grenade launchers, night vision equipment, mortars and rocket launchers.

Generally speaking, urban warfare is more unfavorable to the guest army, mainly because the terrain in the city is complex, and the guest army is often unfamiliar with the terrain, while the main army can occupy the commanding heights and transportation points of the city before the war, and take advantage of its familiarity with the terrain to constantly change the location to strike at the enemy army that is stronger than itself.

But in this era, the crossing army has an absolute advantage in technology, there are drone reconnaissance in the air, and the disadvantage of being unfamiliar with the terrain can basically be compensated, but it has an absolute advantage in weapons, and more importantly, the tactics of urban warfare are not comparable to the army of this era.

The defensive arrangement of the concession has been clearly understood by the army through the reconnaissance of the drone, so the commander Qin Yuhai will attack the main aspect of the Baotu Road (now Yingkou Road), this road is also the dividing line between the British Concession and the French Concession, so this road is chosen to be the main direction of attack, that is, to cut off the concession waist, divide it into two pieces, and then break it one by one.

However, the concession side naturally also knows the importance of the Baotu Road, so it has also made a key deployment here, only the soldiers guarding it have reached more than 300 people, accounting for more than one-third of the entire concession army, as well as two Makqin machine guns, and at the intersection with sandbags to build a fortification more than one meter high and nearly two meters wide, and there are also a lot of soldiers in the buildings on both sides of the street, even if the defense line is breached, but when the enemy army advances along the Baoshi Road, it will still be hit fiercely on both sides. Bauer still has a lot of confidence in this line of defense, and if the enemy army does not have medium and large caliber artillery, if he wants to break through this line of defense, he will have to pay a lot of price.

Of course, Qin Yuhai did not easily order the soldiers to attack the defense line of the concession, because this kind of urban attack and defense city could not be attacked rashly, and if it was not done, it would be turned into a meat grinder. You have to disrupt the opponent's defense first. And at this time, the two mortar platoons in the crossing army also had a moment of power.

The two mortar platoons were divided into two groups and took turns to bombard the concession line, and the fortifications made of sandbags had a good defense against shells, but there was nothing they could do about the shells, which were shells with large curves and ballistics like mortars.

The shells continued to fall into the positions of the concession and exploded, blowing up the unprepared defenders, killing and wounding countless people, although the soldiers in ambush in the houses on both sides fired back, but they had no choice but to cross the army's positions beyond the range of rifles, let alone mortars, so there was almost no threat to the crossing army.

And as soon as the fire was fired, the location of these soldiers who were ambushed in the houses was exposed, so the snipers who crossed the army immediately began to snipe. There are a total of nine snipers in the crossing army, although at a distance of about 800 meters, no matter how good a sniper is, it is impossible to achieve a hundred shots, and it is still possible to achieve a hit rate of six or seven out of ten, so many soldiers who shoot in the house are killed by headshots.

Of course, the snipers are not only sniping at the soldiers in the houses, but now the defense line of the Baoshitu Road has been disrupted, and the soldiers in the concession have become a mess, and almost all of them have become targets for rent.

At this time, Bauer and Fukushima An were commanding and watching the battle in a small building about a hundred meters away from the defense line, watching the defense line they had carefully built was easily disrupted by the enemy, although Bauer was annoyed, but he was helpless, who thought that the other side had so many artillery, fortunately, the defense line was blown up, but the damage to the house was not large, which also made Bauer a little relieved, and now he can only pin his hope on the time when the other party officially launches an attack, so that the ambush in the houses on both sides of the street can also play a role. Therefore, Bauer also immediately ordered the soldiers who had retreated from the defense line to retreat into the houses in a hurry, just waiting for the other side to attack.

And Fukushima Yasumasa has been quietly watching the battle, and he is also assessing the combat effectiveness of the enemy army in his heart, judging from the current situation, although the opponent has cleanly broken up the defense line guarding the treasure road, but from a tactical point of view, it can only be regarded as a medium basis, which is nothing more than the first use of artillery bombardment, and then send infantry to charge.

But at this moment, I saw a flash of fire suddenly fly out from the opponent's position, and suddenly hit a house on the side of the road. This is a standard European-style house, the area is not large, estimated to be less than 200 square meters, but it is two floors, upstairs and downstairs are equipped with tall floor-to-ceiling glass, in this small building ambush more than a dozen soldiers.

I only heard a loud "boom", a large number of fireworks poured out, and the small building was blown out of a large gap several meters wide, followed by two more fires flying by, both hitting the small building. This time, Fukushima Yasumasa saw it more clearly, and it turned out that the fire was from a cylindrical object with a slender vertebrae, and the tail erupted from something similar to the tail feather-like part of an arrow, which looked like an amplification of something like a monkey or a cupola in fireworks.

However, Fukushima Yasumasa knew that this was not fireworks, with two loud explosions, almost half of the small building was destroyed, and two soldiers who were ambushed in the small building were hit by the impact of the explosion and broke through the floor-to-ceiling glass on the second floor, flew more than ten meters away, and fell in the middle of the road.

Seeing this, Bauer's eyes widened and he muttered, "This...... What kind of weapon is this?"

And Fukushima Yasumasa looked at the enemy's position from afar, as if he wanted to see what kind of artillery the tail fire-breathing shell was fired from. At this time, the two sides were nearly a kilometer apart, and they couldn't see it at all.

The PF98 120mm rocket launcher used by the crossing army is, of course, a multi-purpose rocket, but it is easy to penetrate the brick wall. And the 120-mm warhead can be considered a large caliber in artillery, and the power of the explosion cannot be underestimated, and it can be said that it is the most powerful among individual weapons. In this crossing army, there are six PF98 type 120 mm rocket launchers, two for each company, which are effective weapons against light armor, infantry fighting vehicles, field fortifications, warehouses and the elimination of living forces, and to a certain extent, can compensate for the weakness of insufficient heavy firepower.

Seeing that a small building had been destroyed, Qin Yuhai was very satisfied, and immediately ordered the bazooka men to clear the houses with soldiers in ambush one by one. Although the order given to the troops by the headquarters before the war was not to damage the buildings in the concession as much as possible, there was such a good thing in the beginning of the war, not to mention that the enemy had already arranged a defensive line, and only the Japanese with a stubborn mind would play "Pig Burst Jade Crush" and "Banzai Charge" to the death. Of course, Qin Yuhai would not use the lives of the soldiers to fill the position, and first use the bazooka to destroy all the nearby buildings.

In a short period of time, the crossing army had destroyed five houses in a row, and the soldiers in ambush were either killed or wounded, and several soldiers were burned by the fire that ignited in the houses, and the people fled to the streets, shouting and scurrying, and the situation was unbearable. When the soldiers in ambush in the other houses saw it, they dared to continue to hide in the house and wait for death, so they hurriedly fled one after another. In the blink of an eye, the defenses all crumbled.

Qin Yuhai saw this, so he ordered the troops to launch an attack on the concession.

Seeing that the enemy army jumped over the defensive line and rushed into the Baoshi Apprentice Road, Fukushima Yasumasa said to Bauer: "Colonel, let's also retreat, the defense line has been lost." ”
