The old devil stood in place and thought carefully for a moment, and his face quickly returned to calm.

For a long time, Tu Feiyuan, the head of the secret service, has studied the intelligence information of the security group.

Although Tu Feiyuan did not wrestle with Li Hong's security regiment face-to-face on the battlefield, he still knew a lot about the security regiment and knew the combat effectiveness and weaponry of the security regiment.

The firepower of the security regiment is indeed strong, with armored units and air fire support.

It's just that, after all, the security regiment is only the size of a regiment, and there is a huge disparity between the strength of the two divisions of the Japanese army, which is the weakness of the security regiment.

Tu Feiyuan thought in his heart, the number of fighters in the security regiment is limited, and even if it is a wheel war, it will kill the security regiment.

Dofien glanced at Yoshino Taro next to him, and said: "Yoshino-kun, don't be frustrated, although the security regiment is very strong, but the other national army units are very weak, there is no need to worry at all, we only need to jointly deal with the security regiment to break through Xuzhou City, and wait for the annihilation of the security regiment, and the history of the Japanese Army will be rewritten by you and me......"

"Yo Xi!"

When Yoshino Taro heard Madoka Dochi say this, he quickly became a little more confident again.

"Tuhihara-kun, what you said is extremely true, after all, the security regiment is alone, and the final victory must belong to our Imperial Japanese Army!"

Subsequently, the two old devils, Dohi Yuan and Yoshino, strode into the headquarters and redeployed the offensive strategy.

……

The officers and generals of the two divisions of the devil, after some discussion, formulated a battle plan for attacking Xuzhou.

The little devil's fire reconnaissance unit suffered a loss before, and this time the little devil is ready to invest a large number of troops in a fierce attack.

Half an hour later, all the attacking troops of the devils were assembled.

The 9th Division and the 14th Division of the Little Devils each invested a combat wing, and the total strength of the Devil's attack was nearly 7,000 people.

In addition, the little devil also mobilized a large number of chariot groups, as well as many heavy artillery support.

The devils attacked at the same time in two ways, attacking the north gate and the east gate respectively.

The 19th Infantry Wing of the 9th Division attacked the defense line of the east gate, and the 2nd Infantry Wing of the 14th Division of the Japanese Army attacked the defensive line of the position north of the city.

The devil's heavy artillery troops were in full array, and the artillery aimed at the defensive positions on both sides outside Xuzhou City.

"Artillery attack, destroying the defensive !! of the positions of the soldiers in China"

"Artillery attack, destroying the defensive !! of the positions of the soldiers in China"

Under the orders of the commander, more than a dozen large-caliber artillery pieces launched an artillery bombardment together.

In fact, there are far more than a dozen heavy artillery pieces in the two divisions of the little devils.

Because the commander of the devil knew very well that the security regiment had flying troops, in order to avoid the artillery positions being hit, the devils did not dare to expose all the artillery positions.

"Tom !!"

"Tom !!"

On the devil's artillery position, a muffled and far-reaching shelling sounded.

Large-caliber artillery shells flew out from the devil's artillery positions and flew densely towards the front-line positions of the security regiment.

A few seconds later, the shells slammed down on the positions of the security regiment to the east and north of the city.

"Boom, boom, boom!!"

The explosion was deafening, and the enemy's large-caliber shells exploded in all directions, and huge shell craters were everywhere, and dirt and shrapnel were flying everywhere.

The killing range of large-caliber shells can reach the level of 100 meters, and the explosion power is very terrifying.

The artillery fire of the forward position of the security regiment flickered, and there was a violent shock, and the stones on the ground shook to a height of more than ten meters.

The forward positions of the 1st Battalion, the 2nd Battalion, and the 5th Battalion were hit by the devil's heavy artillery, many bunker fortifications were destroyed by shells, and the trench fortifications also collapsed.

The devil's heavy artillery is very strong, and after repeated bombardment, the forward position of less than a kilometer has become devastated, and there are countless large shell craters at the wellhead.

According to the artillery offensive of the little devils, it will not be long before the forward position of the security regiment will become a scorched earth, and the defenders will suffer heavy casualties.

Of course, Li Hong knew the enemy's offensive routines well, and before attacking, he would definitely rain out fierce artillery fire.

Therefore, Li Hong notified the front-line troops outside the city in advance and withdrew the troops guarding the front.

These axes of the enemy may be useful to other national army units, but they have no practical effect on the security regiment.

The security regiment has strong firepower, and even if the soldiers take the initiative to evacuate the forward positions, they can rely on the strong firepower to recapture the positions.

Devil shells flew in waves, and the explosion sounded like muffled thunder.

The enemy bombarded continuously for more than ten minutes, completely plowed the forward positions of the security regiment in the east and north of the city into a scorched earth.

Thick smoke of the explosion filled all corners of the position.

"Boom, boom, boom......"

After a while, the devil's artillery attack weakened, and the number of shells fired was not as dense as before.

Soon, the little devil combat troops launched an attack on the positions in the east and north of the city.

"Imperial soldiers, take the position in front and give the duck and chicken to the !!"

"Imperial soldiers, take the position in front and give the duck and chicken to !!"

The devil commander gave an order, and the little devil entered the army as a unit, divided into several echelons to attack in turn.

Dozens of chariots lined up in front of them, and more than 1,000 devil soldiers kept in formation and followed closely around the chariots.

The little devils mainly attacked the positions outside the east of the city and launched a large-scale offensive like a sea of mountains.

The enemy's infantry, under the cover of artillery fire and combat vehicles, moved rapidly, approaching the positions of the security regiments at the front.

The artillery fire of the heavy artillery units in the rear of the devils continued, however, the shelling was not very violent, and the enemy artillery only suppressed and covered the attack of the large army......

In front of the frontline position of the security regiment, at a glance, all the devil soldiers wearing yellow uniforms were all ghosts.

The enemy's attacking troops, numbering in the thousands, rushed towards the position of the security regiment like a tidal wave, and the momentum of the attack was very great.

Li Hong saw that the big army of the little devils was pressing up on all fronts, and he immediately ordered the artillery units on the front line to move the 75-mm and 105-mm multiple rocket launchers forward by two kilometers.

MLRS have a limited range, but fortunately, MLRS are flexible in their movements, and their position can be moved forward to effectively hit enemy targets.

The enemy's attacking troops charged for more than ten minutes, and soon, the little devil advanced to about 1,500 meters away from the forward position in the east of the city.

This distance was already within the range of the heavy machine guns and mortars of the security regiment, but Li Hong did not immediately order the troops to open fire.

He wants to let the follow-up troops of the devil get closer, and as soon as the enemy comes up, the security regiment will fire and strike hard, which can kill and injure more devil troops.

The artillerymen of the security regiment in the front-line positions, under the instructions of Li Hong, prepared incendiary bombs and smoke bombs, and each machine gun group prepared sufficient ammunition.

In the blink of an eye, the devil's chariot group rushed to the front line of the first and second battalions 1,000 meters, and immediately, the heavy artillery unit in the distance of the devil stopped shelling the position of the security regiment.
