Shanghai.

This is different from Nanjing, Luoyang, Taiyuan and other cities, because in ancient times, Shanghai did not get much attention, and it was not until modern times that it gradually developed.

Officially, because of this, Shanghai did not have any strong city fortifications, let alone ancient buildings and institutional defenses.

The Japanese army used buildings and roof walls as fortifications in Shanghai to resist the fierce attacks of the iron-blooded brigades.

Therefore, once the outer defense line was broken through and Shanghai was attacked, it meant that the Iron Brigade would have to engage in urban warfare based on street battles and building battles.

Afternoon: 17:30.

At this time, the siege force of the Iron Brigade had completely broken through the outer defense line of the Japanese army and began to launch a fierce attack into the city.

"Kill......"

"Rush, ......"

The little devils in Shanghai began to rely on the high-rise buildings and streets and alleys in the city to engage in the fiercest urban battles with the Predators.

"Dada......"

"Puff ......"

The two sides are in the confrontation of heavy fire back and forth.

However, because the Iron Brigade is really fighting in the city, it is generally at a disadvantage in terms of terrain.

The streets and alleys of the city are crisscrossed, the buildings are tall, solid, and dense, the underground engineering facilities are complex, and the combat conditions are harsh.

Shanghai is a metropolis, and in this metropolis clock, the defending side can use tall buildings and underground engineering facilities in all directions to build a strong fortress; A large number of mines and various obstacles can be set up in urban areas; It can be condescending, with point control surface, observation and sniping; Buildings and blocks can be used to organize crossfire.

Therefore, the Japanese army fought in Shanghai because of the terrain and conditions.

However, for the iron-blooded brigade on the attacking side, it is often necessary to attack the fortified points and fight in the streets, and the terrain and enemy situation are unknown, so they are vulnerable to enemy ambushes and cold shooting.

In addition, in urban warfare, limited by the terrain, troops and weapons mainly move along the roads and the streets and alleys on both sides, so the battle formation is easy to be separated, which is not conducive to the activities of large corps, and small detachments will play a great role.

After entering the city, Lei Zifeng, Zhou Weiguo, He Jun, Li Xiangyang and others were also aware of this problem, and they paid the price of blood several times when they advanced!

"It's harder to fight in this city than it is on the periphery, damn it!" Li Da was a little impatient.

However, before attacking Shanghai, Li Yunlong was aware of this problem, so he had already formulated a strategy for urban warfare for everyone.

"The division commander explained before that once you enter Shanghai to conduct urban operations, then you can't carry out large-scale corps!" Zhou Weiguo said: "We should concentrate our advantages and focus on breakthroughs. Multi-way attacks. Divide the encirclement and annihilation, seal the encirclement, and raise multiple hands at the same time! ”

"Therefore, in the next operation, the platoon will be used as the combat unit, and the combat method of fighting separately will be adopted, and there is no need for unified command, and all the little devils and traitors and lackeys in the city must be killed!"

In urban combat, because of the obstruction of tall buildings and buildings, it will be very difficult to command, especially during World War II, when communication was still very backward, so it is the best combat strategy to divide into squads!

"Yes!"

In accordance with Li Yunlong's previous layout, everyone began to notify the troops to use the platoon as a combat unit to enter the city of Shanghai to fight!

"Dada...... Bang bang bang ......"

"Sudden ......"

When a platoon of the Iron Brigade encountered the little devils, it immediately began to shoot fiercely.

There weren't many little devils encountered this time, about the strength of only one squad.

The two sides engaged in fierce confrontational shooting in a small bungalow building.

"Machine gunner cover, sharpshooter fire support, rush!"

The platoon commander of the Iron and Blood Brigade quickly and flexibly commanded the operation, and soon led the soldiers to attack the small bungalow occupied by the little devil and solved the little devil in the small bungalow.

At this time, such battle scenes were staged in Shanghai.

····

Urban operations are always small, and most of the people engaged in battles with the enemy are squads or platoons, and their troops are scattered, making it difficult for them to command and coordinate. Therefore, it is conducive to "fighting alone" and not to joint action.

However, the individual combat power of the Iron Blood Brigade is not weak, so in the individual soldiers or small detachments in this city, it is not inferior at all.

The Japanese puppet army has a certain advantage in the buildings and alleys in the city as battlefield fortifications, but the Predators have a certain advantage in individual combat, weapons and equipment, and numbers.

Therefore, since the division of troops into small units, the battle of the Iron Blood Brigade in Shanghai began to slowly turn defeat into victory.

The little devils, traitors, and lackeys in the city are constantly decreasing.

.......

General Headquarters of the Shanghai Garrison Force.

At this time, the entire headquarters was already in chaos, because the outer defense line was breached, and the whole of Shanghai was not calm.

Sekiya Harukawa originally wanted to contact Kawabe Nisaburo to ask about the situation of the Third Fleet, but he sent several telegrams in a row without any response.

It is clear that the Third Fleet has also ceased to exist.

"Report to the commander, the vanguard of the Chinese Army has entered Shanghai and arrived at Guanghan Road!" A guard ran in briskly to report.

"Shanghai, this can't be held!"

In just a few hours, the old devil Sekiya Harukawa seems to have aged a lot all of a sudden!

Shanghai, a very important port and coastal city, was geographically more important than Nanjing, because it was the export port for the Japanese army to plunder strategic materials.

But now it can't be held.

Defeat is assured!

A chief of staff next to him looked at Sekiya Harukawa like this, and asked cautiously: "Your Excellency Commander, what is the next combat strategy?" Want to retreat? ”
