Northern Poland, on the border line. Long northern defensive positions in a corner.

"Boom!" a shell landed near the reinforced concrete bunker, kicking up a cloud of rubble, and then gradually subsided, leaving only a slowly rising wisp of black smoke. The shell exploded a section of barbed wire, and the broken wire shook twice, making the seemingly dilapidated position even more lonely.

The disadvantage of Germany's lack of heavy artillery was finally manifested in the northern Polish defensive line, because the Mordrin Corps in northern Poland did not leave the fortified areas on the border, so the P Army Group in East Prussia has not been able to break through the Mordrin Corps defense line from the front.

The largest artillery of the Wehrmacht was 150 mm, and this firepower was convenient for the mobility and transportation of troops, but there was no way to take the fortified line alone. The German artillery tried with all their might, but failed to crack the thick Polish border defenses.

A Polish veteran looked at the depression in the distance directly in front of the defensive line from the gap in the fire point of the fortress, and beside him, a water-cooled Maxim heavy machine gun was fixed in the firing position, with almost no recoil and plenty of ammunition, and behind him, three machine gunners and two auxiliary soldiers huddled in a straw-covered corner, taking advantage of the break in the battle to seize the time to rest.

The Germans did not wait for the Polish defenders to abandon their positions and retreat, they would organize tanks and assault guns to make a feint, and retreat after being fired back by Poland.

"The Germans are so capable that they are embarrassed to go to war?" the Polish veteran muttered softly, shoved a straw stick into his mouth, chewed and continued to look through the gap in the firing port to find sunlight, and the occasional shelling made the Poles hide in the concrete bunker, and the cramped and dark inside the bunker was a torment for everyone who longed for freedom.

"Someone is wounded!" a young voice cried out from a distant trench, "Someone! ”

The reason for being hit by this occasional shell was not that the Polish soldier was too ill-conceived, but that the Germans used the attack to cover their snipers and observers and placed the artillery observation posts in a position quite close to the Polish lines. These camouflaged and concealed German soldiers lurked in corners with radios and several days of dry rations, summoning artillery fire to attack the Polish soldiers at the slightest relent.

This style of play made the Polish defenders very uncomfortable, and they sent soldiers to repeatedly attack places that they thought were suspicious, and although they caused more than a dozen casualties to the Germans, they often paid a price ten times more than the Germans. After a few times, the Poles abandoned this stupid way of playing, and no matter how provocative these German soldiers were, they just stuck to their positions and did not go out to fight back.

The Polish veteran spit out the straw stick in his mouth, felt the wall out of the pillbox, bypassed the soldiers resting on the ground in the cement-reinforced trenches, and bent over in the direction of the shouting.

When he walked up to the wounded, there was already a paramedic bandaging the wounded soldier. And next to this unlucky guy lay an even more unlucky guy, the already cold corpse had been pierced by shrapnel from the shell, and its intestines were coiled on the cold concrete floor, and the person had long since lost his breath.

Not far from here, there was a young soldier with a rifle in his arms, and he watched in horror as the medics rescued his comrades, and there was an indescribable depression in his eyes.

"How did these two men get hit?" the Polish veteran asked the young soldier next to him casually, lying on the edge of the trench. He looked at the crater from the shell not far away, which was still steaming hot, with a hint of burnt smell.

"They went to relieve themselves together, and when they thought the toilet was too far away, they climbed out of the trench and went there to squat and smoke, and the result was ......" The young soldier spoke with a slight tremble, but he answered fluently.

"Don't make such a mistake!" the old soldier retracted his head, glanced at the young soldier and said, "The last thing that is lacking here is the idiots who are looking for death, they are in a hurry to go to heaven to serve God, if you are not in a hurry, do not just go out of your bunker, and it is better to stay in the thickest place with the thickest armor and cement." ”

"Thank you, thank you......" The young soldier stared at the veteran and spat out a word of gratitude.

Just as the two of them turned around and were about to return to their positions, the mournful air defense sirens sounded: "Woo......"

Looking at some small black dots like sesame seeds under the white clouds in the sky, the veteran frowned, he always felt very wrong today, it seemed that it was the instinctive fear of dangerous things that he had cultivated over the years of joining the army.

This bad premonition made him stand still and did not move, he chose a V-shaped trench to avoid the blast, and lay on the still slightly cold concrete breastwork, looking up at the approaching Luftwaffe bombers.

On the surrounding positions, the anti-aircraft guns began to fire, and the sound of tom-tom artillery fire was heard, but because of the quantity, it seemed that it had little effect on the German planes in the sky, and soon the German bomber group flew over the positions of the Polish army.

This was not the first time that the Luftwaffe bombed, on the contrary, the Luftwaffe had bombed it several times in the past few days, but with good trenches and thick pillboxes and bulgaries, the losses of the Polish defenders were not large, so the Luftwaffe bombing did not have the effect of causing the Polish army to collapse or retreat.

These Germans are really brainless. Why did you come over again and again when you knew that because the aerial bombs were not powerful enough to cause damage to the reinforced concrete and armored steel fortifications of the Polish defenders like artillery shells?

While this Polish veteran was thinking nonsense, the Luftwaffe bombers had already opened their bomb bays and were ready to drop bombs. Due to the slight interference of the anti-aircraft guns, the formation of these planes was a little messy, but it was not so messy that it affected the bomb dropping.

One bomb fell from the bomb bay of the plane, followed by another bomb, and then, as the rain became heavier, the bomb began to fall densely, and the first bomb dropped directly hit a high ground with three machine-gun bunkers on the other side of the hill.

As usual, the bomb suddenly burst like a burning liquid, and the air generated by the explosion carried the flames in all directions, and the fire instantly rose three stories high, and the tragic burning scene frightened the Polish veterans who had been staring at the bombs dropped by the German planes and knocked their upper and lower teeth into a rhythmic sound.

The second bomb exploded in another place, exactly like the first, and the surrounding soldiers began to stir, and many of them ran out of the trenches and ran towards the open area behind, but soon they were engulfed in the flames of the same bomb.

As the German bomber flew overhead, the explosion soon followed, and the Polish veteran suddenly jumped out of the trench, and jumped into the big crater blown up by the German artillery just now, took a deep breath and held his breath, and curled up in a ball with his head in his hands.

Then he heard the explosion, and then he felt the pain of the wave burning the back of his hand, and then he didn't know anything. It was a long time, when he thought he was dead, that a little more oxygen poured into his lungs, and his whole body came to his senses.

The back of his right hand and exposed areas were burned by Yan zhòng, and his military coat was also blackened. He knew that his right hand must have been ruined, and the right side of his face was also in hot pain, and it looked probably disfigured, but he was glad that he was still alive, because he saw the charred corpse in the trench behind him.

In the distance, a burning fire man was still rolling on the ground, and everywhere he could see the position was charred black, most of them were dead, a few were screaming hysterically, and the entire defensive position of the Polish army was like a realistic version of purgatory on earth.

Unlike previous incendiary bombs, Germany dropped a newly developed secret weapon "napalm", which was specially designed to deal with permanent underground fortifications, which could evaporate the oxygen inside the fortifications, burn the personnel inside, and most importantly, the flames that burned were extremely difficult to extinguish.

The old Polish soldier staggered, looking at the smoke of a sea of fire, not knowing what to do next, and suddenly he saw the iron door of a pillbox being pushed open from the inside, and a burning young face appeared in front of him, and the young soldier was like a flickering torch at this moment, screaming and twisting and struggling in the trenches, and finally fell to the ground and turned into burning black coal.

This qiē happened in just a few minutes......

Suddenly a gunshot rang out, and the Polish veteran saw that his chest was being shot from behind, he struggled to turn around, and found that a German sniper with a gun was firing a second shot at him a hundred meters away, and soon the bullet passed through his throat, and he suddenly felt that the wounds on his right hand and face were no longer hot.

......

"Long live the Führer! An Air Force officer knocked on the door and walked into Catherine's office: "News has just come from the front that the pilots of the 4th Bomber Wing have dropped napalm bombs on the permanent defensive positions of the Polish Modlin Regiment in the northern region of Poland. ”

"What was the result?" Catherine asked, looking at his Air Force combat offensive diagram with her hands behind her back.

"The results were considerable, and it was proved that this weapon had a strong destructive effect on the underground bunkers of the general Cheng dù. The officer replied proudly: "The advice given by the front-line troops is to increase the production of such bombs, which can be used on a large scale when attacking enemy fortifications and cities." ”

"Send a report to the Führer. Catherine nodded: "Just send it according to this construction." ”
