On the night of the first day, the twelve trenches had only advanced more than fifty meters, far from threatening the stronghold.

But Erren could feel it outside, and the atmosphere in the stronghold had become visibly tense.

A flare was fired every half an hour, and there were more Japanese puppet troops on patrol, and as long as there was the slightest movement outside the stronghold, it immediately attracted frantic fire from light and heavy machine guns.

After daybreak, the Japanese called planes, intending to fight out of the stronghold under the cover of the planes and destroy the trenches that the troops had dug last night.

"Company commander, the little devil plane is here again......" Hearing the louder and louder roar in the air, the instructor reminded with a frown.

The Japanese army attacked twice, and the reason why the second company did not stop it was because of the little devil plane.

One after another, they patrolled above the heads of the attacking troops, and when they saw the Eighth Route Army gathering nearby, they immediately pounced, either strafing or bombing.

The Second Company suffered a loss once, losing nearly 40 fighters, and then did not dare to assemble under the noses of the planes, so it could only use guerrilla warfare to sneak attack the enemy.

Seeing the plane coming to the battlefield again, the instructor subconsciously became nervous like a conditioned reflex.

To his surprise, the company commander did not panic after suffering enough losses on the plane, not only was he not nervous, but he also looked confident: "Instructor, when fighting guerrilla warfare with the Japanese puppet army's attack troops, the troops were always in motion and had no way to conduct air defense. Now the troops are fixed outside the stronghold, and although they still can't shoot down the devil planes, we can still do some simple air defense. ”

"Air defense is mentioned in the regimental commander's battle plan, and I'm ready for it."

"Order the troops to release smoke immediately, there is no wind today, and the smoke will always float above our heads, blocking the view of the little devil's plane."

"The heavy machine gun platoon is ready to fire into the air."

"We are very close to the devil's stronghold, and in order to avoid accidental bombing, when the field of vision is blocked, the aircraft can only carry out low-altitude bombing, and then our heavy machine guns can come in handy."

"Even if you can't hit them, you can scare them so that they don't dare to fly low and bomb us."

"Each platoon is ready for battle, if there are little devils who rush out of the stronghold to destroy the trenches, it is still the old rule, use guerrilla warfare to attack them, kill one more enemy if you can, but you must protect yourself."

The instructor suddenly realized and exclaimed, "I understand." ”

"Force out the little devils in the stronghold by digging trenches, and then slowly consume them with guerrilla warfare."

"Kill dozens of Japanese puppet troops at one time, and ten times add up to three or four hundred puppet armies and they will be gone!"

In the fort of the stronghold, after learning that the planes were about to arrive on the battlefield, the commander immediately ordered to prepare for the attack and destroy the trenches that might threaten the security of the stronghold.

"Sir, the Eighth Route Army is putting smoke outside the stronghold...... his subordinates reminded.

In the blink of an eye, nearly a hundred puffs of black smoke had risen from the circle of the stronghold.

It first rose to an altitude of 100 meters, and then began to spread around.

By the time the plane arrived over the base, the gray smoke had already covered the sky over the base.

"I understand, the Eighth Route Army wants to use smoke air defense to block the plane's field of vision, so that they can't find the bombing target." The subordinate who spoke just now suddenly came to his senses and shouted.

The commander looked calm and didn't take this matter to heart: "In the previous two sorties, although the Eighth Route Army did not release smoke, our planes did not attack them, but only cruised above us on alert. The troops still broke through the blockade line of the Eighth Route Army and fought their way out of the stronghold. ”

"So whether they release smoke or not has no effect on us, and the troops can completely rely on their own strength to kill their strongholds."

The subordinates thought for a moment and reminded: "What if they take the opportunity to gather troops and intercept us at the gate of the stronghold?" ”

"That's the best!" The Commander's eyes were visibly hot.

"Our heavy machine guns and mortars are ready, and if they dare to assemble, I will destroy them together."

Ten minutes later, the gate of the stronghold was opened, and dozens of Japanese puppet troops rushed out as the vanguard. ”

"Horn Horn Horn ...... Dadada......"

The blocking battle feared by his subordinates did not take place, and as before, there were only sporadic rifle fire and light machine gun fire outside the stronghold.

The Devil Artillerymen and Heavy Machine Gunners who were on standby in the stronghold all had disappointed expressions.

If the Eighth Route Army gathers at the gate of the stronghold to block the attack, they will still have a place to play.

With this kind of sporadic sneak attack, they can't even lock on to the target, let alone fight back.

There will be nothing to gain except for wasting ammunition in vain.

"All the other sorties were killed, destroyed all the trenches dug by the Eighth Route Army last night, and then retreated to the stronghold." The commander also ordered with a look of disappointment.

The subordinate thought for a moment and reminded: "Sir, since the troops have been killed, and there are planes in the sky to cover, it is better to take the opportunity to go to the nearby villages to sweep once, and then grab some food and supplies and come back." Just destroying some trenches is too wasteful of the opportunity for aircraft reinforcements. ”

"No way!" The commander refused very simply.

"Taking the opportunity to sweep the nearby villages can indeed grab a lot of food and come back, but our troops will also suffer a lot of casualties under the ubiquitous sneak attacks of the Eighth Route Army."

"Don't underestimate the casualties of dozens of people, there are too many times, and these sporadic casualties can also bring us a devastating blow."

"The task given to us by our superiors is to stay here like a nail, and the longer we hold on, the better. Therefore, unless we have to, we must not attack lightly and give the Eighth Route Army a chance to consume us. ”

The subordinates showed a look of sudden realization, and said with a look of admiration and compliment: "The chief is wise, and he has been taught in a humble position." ”

The operation of the Japanese puppet army was very smooth, because of the large use of explosives, in less than half an hour, the efforts of the second company last night were all wiped out in a series of explosions.

However, looking at the troops that were withdrawing from their strongholds one after another, the commander did not have a smile on his face.

His brows furrowed deeper and deeper, and his face became more and more solemn.

"Eight Ge Yalu, we've been fooled!" The commander suddenly shouted.

The subordinates were taken aback by this sentence and looked at the commander with a puzzled expression.

"Don't you see it yet? Although the trenches outside were destroyed, we lost another two dozen soldiers. The commander explained, pointing to the corpse outside the stronghold.

"After dark, the Eighth Route Army can continue to dig trenches and approach the stronghold, and if we continue to attack, we will definitely lose more than two dozen soldiers."

"If it continues like this, in less than half a month, all the garrisons in the stronghold will be exhausted."

The subordinates suddenly realized and shouted: "Sir, what do you mean: the Eighth Route Army forced us to kill our strongholds by digging trenches, and then took the opportunity to use guerrilla warfare to consume us. ”

"Not bad!" The commander affirmed.

"The number of times we attack and grab food on our own is too small, and the Eighth Route Army uses this method to increase the frequency of our sorties, and then speed up the consumption of us, and then eliminate us."

The more he said, the commander's face became more and more ugly, and finally he ordered with a serious face: "We can't be fooled anymore, from now on, without my order, no one can attack without authorization, and create an opportunity for the Eighth Route Army to consume us." ”

"If the Eighth Route Army wants to dig trenches, let them dig them, we have the advantage of troops, we have impregnable turrets and dark bunkers, and we are not afraid that they will shorten the offensive distance."

The commander of the stronghold was right, and that night, the 2nd Company not only repaired all the trenches they had destroyed during the day, but also pushed the trenches forward by another 30 meters, bringing them closer to the stronghold.

Before dawn, the company commander began to evacuate the troops, preparing firewood and grass for smoke to meet the attack of the Japanese puppet army.

At ten o'clock in the morning, the plane did not arrive at the battlefield as promised.

At eleven o'clock, the plane had not yet arrived, and there was not the slightest movement in the stronghold a few hundred meters away.

The guard posts and patrolmen who can still see some figures in ordinary times also hid in the artillery towers and hidden bunkers today, staring at every move outside through the shooting holes to prevent being killed by the cold guns and cannons of the Eighth Route Army.
