"Company commander, the devil seems to have seen our purpose." The instructor reminded with a frown.

"Not only did they not come out to destroy the trenches, but the security was also stricter than before, and the vigilance was also stronger, such a large stronghold did not even have a Japanese puppet army with their heads exposed, and we didn't have a chance to shoot coldly."

The company commander replied confidently: "Don't worry, we still have a backhand." ”

"They can endure digging trenches, and when I sacrifice the back hand that the head of the regiment prepared for us, they will definitely not be able to bear it."

"Since the little devil doesn't come out, then we will continue to dig trenches, send two soldiers over each trench at a time, continue to dig towards the stronghold, and change people once an hour."

"There are no soldiers on the wheel, except for the guard post, everyone else is resting."

"Strive to dig the trench to 100 meters outside the stronghold for another two days and two nights, and then connect it to block the ditch in a circle to ensure that the soldiers can move around safely and freely inside."

On the top of the stronghold's turret, looking at the blockade ditch that was already close at hand outside the stronghold, the commander had a solemn face.

The frequency of flares has been accelerated from once every half an hour to once every fifteen minutes now.

At all times, a third of the troops in the stronghold were on standby.

The offensive position of the Eighth Route Army was too close to the stronghold, and a quick assault could reach the side of the dark fort in half a minute at most.

If there are fewer troops defending and the Eighth Route Army launches a surprise attack, the bunker does not shoot strong enough firepower, and it is easy for the Eighth Route Army to drill a leak, touch the side of the bunker, and destroy the bunker with explosives packs.

Not only that, but the cautious commander also ordered the troops to find out the stronghold at night and lay a lot of mines outside.

The bunker was also surrounded by steel wire mesh, and empty cans were covered with it.

If someone sneaks up, they will definitely touch mines and canning boxes, alerting the troops in the stronghold to prepare for battle.

After a series of arrangements, the defense of the stronghold can already be called airtight and impregnable.

Unless they voluntarily abandon their strongholds, it is impossible for the Eighth Route Army to attack them, even if their attack distance is only a hundred meters.

But tonight, since dark, the commander has a bad feeling in his head.

A soldier's sixth sense, especially the ability to perceive danger, is several times higher than that of ordinary people.

The Commander was no exception, and there was always a feeling that something big was going to happen tonight.

After eating, he stood on the top of the turret, staring at the offensive position of the Eighth Route Army, trying to see some clues.

It's so quiet outside the stronghold that anyone who has tried a little military knows it: the quieter the battlefield, the more abnormal the situation, which means that the opponent must be brewing some bigger conspiracy.

The commander's brow furrowed deeper and deeper, and he searched outside the stronghold over and over again, but found nothing.

"Boom ......"

An explosion from behind him startled him, and when he turned around, he saw a ball of flames erupting from the position of the Eighth Route Army outside the stronghold in the direction of the stronghold, and a black shadow the size of a disc rolled and flew towards the stronghold, the speed was very slow, and it could be seen clearly by the naked eye.

"It's flying thunder artillery, and the artillery immediately counterattacks and destroys their artillery positions......"

As soon as he finished speaking, a fireball rose in the middle of the dark castle group behind him, and the flames splashed in all directions, and the billowing smoke mixed with it rose into the air.

Immediately after, the explosion of "booming ......" reached the ears, and the ground shook.

The commander stood on the roof of the turret, at least a hundred meters from the point of impact, and still felt the scorching heat from the explosion rushing towards him.

The solemn face quickly showed an expression of sudden realization, and he exclaimed, "I understand." ”

"The Eighth Route Army advanced the offensive position to a position 100 meters outside the stronghold, which can not only shorten the offensive distance, but also deploy flying thunder cannons to throw explosive packs at the stronghold."

"Although the reinforced concrete bunker is very strong, if the explosive package thrown by the Eighth Route Army is large enough to hit the bunker, even if the bunker is not destroyed, the soldiers inside will be killed and injured by the shock wave and lose their combat effectiveness."

Speaking of this, the commander's face became more and more solemn, and he hurriedly shouted: "Why haven't the artillery opened fire yet, if you want to relieve this crisis, you can either destroy the blockade ditch outside and drive the Eighth Route Army to the original offensive position, so that the flying thunder artillery can't reach our stronghold." ”

"Either destroy their Thunderbolts so they can't throw explosive packets into our stronghold."

"The first method will definitely not work, and the troops will give the Eighth Route Army a chance to continue to consume us."

"And even if we destroy this blockade ditch, they can dig a new blockade ditch and force us to continue to send troops and continue to consume us."

"So we can only find a way to destroy the flying thunder cannons so that the explosives pack can't hit our stronghold."

"Tom Tom ......"

The mortar fire finally rang out, and not far from the turret, the commander could clearly see the flames and smoke ejecting from the muzzle.

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

Four shells smashed into the thunder artillery position and exploded, flying fire, gunsmoke, and dirt...... Quickly shroud there.

The commander breathed a sigh of relief.

As long as the Flying Thunder Cannon has not been transferred there, it will definitely be destroyed.

Before he could rejoice, an explosion of "boom ......" rang out again, and it was in the other direction of the stronghold.

The Commander looked back and saw the same picture, and then heard a earth-shaking explosion sound from inside the stronghold, sending fireballs and black smoke into the air......

"There are also flying thunder cannons on the north side of the stronghold, and the artillery will immediately turn around and counterattack......" The commander frowned again, and ordered in a hurry.

The artillery squad was destined to be the most tired unit tonight.

Hurriedly turning the mortar, firing the first round of shells, the shelling of the flying thunder cannon sounded again, to the east of the stronghold.

The leader of the artillery squad reacted quickly, and without waiting for the commander to give an order, he directly asked his subordinates to start turning after firing two rounds of shells, shelling the flying thunder cannon that had just been exposed.

Outside the stronghold, the company commander was very excited.

The battle was developing along the lines he had envisioned.

It took at least a minute for the Japanese to move the direction of the mortar, to lock on to the target of the shelling, to finally open fire.

This time was enough for the artillery under his command to carry the flying thunder cannon and move forty or fifty meters.

So the Japanese counterattack had no effect, and the six flying thunder guns were intact.

All activities were carried out in the blockade ditch, and explosive packets were thrown at the stronghold one after another.

"Company commander, we have locked the little devil artillery position, and after fighting for so long, they have not shifted their position." The mortar platoon commander came over and reported expectantly.

"The old rule, three rapid shots per cannon, transfer when the fight is over, and kill a few devils." The company commander ordered decisively.

On the stronghold artillery tower, the commander's face became heavier and heavier.

The artillery squad had fired dozens of shells, but the flying thunder guns equipped by the Eighth Route Army did not seem to be affected, and they continued to shoot one after another.

Just as they were about to fire, the second company of mortars opened fire.

The artillery position not far away instantly exploded several fireballs, and in the flying firelight, the commander clearly saw that several soldiers were blown away!
