On April 18, the first day of the attack on the mountain fortifications outside Darkhan by the Russian First Siberian Front, the Russian army threw all its might, and even in the evening, the Russian army's attack did not stop, and the theater commander Kuropatkin sent another 1 corps of the fourth wave of attack forces to continue to strengthen the offensive on the 8 mountain fortifications on the front.

And the two Russian infantry corps, which were the first to launch an offensive today, finally received an order from the commander of the theater of operations, Kuropatkin, to retreat from the sea of corpses and blood to rest.

After the two armies retreated, as soon as the number of people was counted, the commanders of the two armies couldn't help but burst into tears, the army that launched the first wave of attack was nearly 30,000 people, and at this time there were less than 8,000 people who could retreat, and the army that attacked in the second wave was less than 10,000 people, and many of the officers and soldiers who withdrew were still wounded, and the tragic situation of these two armies could not be described with the word heavy casualties.

The staff officer of the command reported the losses of the two armies to Kuropatkin, and Kuropatkin trembled after hearing this, but nodded with no expression on his face and said: "Let the two armies rest and recuperate, and tell the two army commanders that if the war is tight, their two armies may also be sent to the front line to take up the attack mission." ”

The staff officer of the command trembled when he heard this, the two corps had suffered more than two-thirds of the casualties, and the commander was ready to let them attack, which was really a cost, but the staff officer of the command did not dare to say anything, and immediately took the order to inform the two heartbroken army commanders, this order that almost poured salt into their wounds.

In addition, there were about 300 soldiers of the army belonging to the third wave of attack, and when they saw the retreat of the first and second waves of Russian officers and soldiers, they were even confused or lucky to retreat, and the commander of the theater of operations, Kuropatkin, heard this, waved his hand, and ordered the overseers to immediately execute the more than 300 Russian soldiers who had retreated without receiving the order, on the spot, to set an example, and to inform the entire Siberian First Front.

The Russian offensive has not stopped, the offensive has been launched all night, and by the early morning of April 19, the Russian army has sent 6 waves of attacking troops, that is to say, the Russian army has dispatched 6 corps, and last night Kuropatkin sent the fifth and sixth waves of attacking troops, and the third and fourth waves of attacking troops in front did not withdraw.

Although the Russian army's crazy attack has paid a very big price, it has really made the Russian army achieve some results, the mountain fortifications outside Darkhan blocked the 8 mountain fortifications in front of the Russian army, a large number of pillboxes and bunkers were blown up by the Russian army with explosives bags regardless of casualties, and even many bunkers and bunkers were occupied by the Russian army. The Dingbei Army, which guarded the mountain fortifications, also paid a lot of casualties.

Some Russian troops even attacked the interior of the tunnel along the mouth of the tunnel where the occupied pillbox and the bunker were connected, so that the officers and soldiers of Dingbei in the tunnel had to blow up many tunnels connected to the bunkers and bunkers occupied by the Russian army, so as to prevent the Russian army from attacking the inside of the tunnel and attacking the bunkers and bunkers that were not captured by the Russian army.

After the fight, the Dingbei Army did not organize a counterattack on the bunkers and bunkers occupied by the Russian army, after all, the casualties of such a counterattack were too large, so as long as the bunkers and bunkers were occupied by the Russian army, the Dingbei Army immediately used explosives to blow up the tunnels connected to these bunkers and bunkers, which directly cut off the opportunity for the Russian army to attack inside the tunnels.

In the early morning of April 19, most of the pillboxes and bunkers on the top of the eight mountain fortifications in front of the Dingbei Army had been lost, and Ni Fan, the commander of the Third Division, who was the commander of the entire Darkhan City, saw the situation of the eight mountain fortifications on the front, thought about it, and issued an order to the troops guarding the eight mountain fortifications to retreat to the mountain fortifications behind through the guò tunnel, and ordered the retreating troops to blow up the tunnels connected to the other mountain fortifications when they withdrew. Don't let the Russian army attack the inside of other mountain fortifications behind these tunnels, it will be too bad.

Liu Dayan was using a Type 96 heavy machine gun to shoot at the attacking Russian troops outside the bunker to prevent these Russian troops from approaching his bunker. This bunker is not big, there are only 2 firing ports, guarded by 1 squad of Liu Dayan, 1 Type 96 heavy machine gun and another 96 light machine gun, which are allocated to this bunker.

At this time, Liu Dayan, who had not slept all night, kept pulling the trigger with red eyes, and most of the other firepower points near his dark fort had been destroyed by the Russian army, and Liu Dayan, who was shooting, was actually secretly bitter in his heart, although his squad guarded this dark fort, the casualties were not big at present, his squad guarded this dark fort close to the top of the mountain, and the Russian army did not attack this dark fort for a long time, only 2 soldiers were killed by Russian bullets flying from the firing port when they were shooting with machine guns, and the other 8 people were unscathed, But if the other bunkers and bunkers around are lost, and their bunkers can't hold out for long, the Russian army can go around the head of their bunkers and throw explosive packs or grenades into the bunkers.

If then the bunker guarded by his squad is likely to be blown up, or blow up a big hole, if it is blown up, it is fine, at most he will sacrifice himself in this bunker, and realize the oath that people are in the position, and if he is lucky, he can also take the remaining soldiers and move to other bunkers or bunkers to continue fighting.

What makes Liu Dayan frown is that if you just blow up the bunker, it will be troublesome, the bunker is connected to the tunnel, if the Russian army attacks the bunker they are guarding into the tunnel, they will not close their eyes even if they die in battle.

So Liu Dayan shouted to the deputy squad leader in the bunker while shooting: "Hammer, you take 3 soldiers into the pit immediately and prepare explosives, if the Russian army blows up the bunker, you will blow up the pit with explosives, and you must not let the Russian army attack the inside of the pit along the bunker we guard." ”

The deputy squad leader, nicknamed Hammer, was using a Type 96 light machine gun allocated to this bunker at this time to fire fiercely at the Russian troops who were trying to get close to the bunker outside, and when he heard his squad leader's shout, he immediately shouted: "Big eyes, you still retreat to the tunnel with a few people, your children are still young and need you to take care of them, my brother is one, there are a lot of brothers and sisters in the family, and my father and mother are also taken care of, I will stay!" ”

There are few other pillboxes and bunkers around the bunker in their squad to guard the firepower points of the bunker, and the officers and men of Dingbei who cooperate with the bunkers and bunkers to guard the mountain fortifications in the trenches on the surface of the mountain have suffered very heavy casualties because of the continuous bombardment of Russian artillery fire, and several waves of officers and soldiers have been sent into these trenches on the surface in the tunnel, but there is not much left at this time.

As long as the Russian army goes around to the head of their squad guarding the bunker, they don't want to hold this bunker, and those who stay in the bunker will not be killed, and they won't want to survive the subsequent attack of the Russian army.

Liu Dayan shouted loudly: "What are you talking about, I am the squad leader, obey the order!" Quick, take people into the pit now and prepare explosives! ”

The deputy squad leader still struggled with his hammer and said: "Big eyes, you take people into the tunnel, I ......"

Before the hammer's words were finished, a man ran into the back of the pit and shouted: "Why can't you get through the phone in the dark fort, quickly, follow me to the pit and retreat, the superior ordered to abandon the 8 mountain fortifications in front." ”

The trigger in Liu Dayan and the hammer's hands did not stand up, and when he heard the voice, he looked back and shouted in unison: "Company commander!" ”

After receiving the order of the commander Ni Fan, the officers and soldiers of Dingbei guarding the eight mountain fortifications in front of the army, after inflicting a large number of casualties on the Russian army, retreated from the tunnels connected between the mountain fortifications to the mountain fortifications behind, and in order to prevent the Russian army from using these connected tunnels to attack the mountain fortifications behind, all the connected tunnels were blown up with explosives.

After the officers and soldiers of the Dingbei Army, who were guarding the eight mountain fortifications in front, retreated to the mountain fortifications behind, they received an order from the commander Ni Fan to continue to retreat backwards, until they retreated to the city of Darhan, and when they returned to the city of Darkhan, the casualties of each unit were counted, and the number of casualties was nearly 5,000, and more than 1,000 officers and soldiers were injured.

After the commander Ni Fan got the casualty figures, he shook his head helplessly, in such a tragic offensive and defensive battle, casualties are inevitable, although the eliminated Russian army is at least more than 10 times the number of casualties in his own troops, but it has been less than 24 hours since the Russian army launched the attack, and there have been so many casualties, this is still because the Dingbei Army occupies the advantage of mountain fortifications, that is, Ni Fan, who has experienced the bloody battle of buying and selling cities, can't help but be secretly frightened by such casualties, it seems that the Russian army is really fighting this time.

The Russian army attacked the 8 mountain fortifications in front of him all night, and the commander of the theater of operations, Kuropatkin, had not slept either, waiting for the news of the attacking troops in the command headquarters of the camp behind, and seeing that the sky was already dawning, he was about to order the troops of the 1st army to launch the seventh wave of attacks and reinforce the attack troops of the third to sixth waves, at this time a staff officer of the command headquarters ran in out of breath and shouted with a happy face: "Commander, the 8 mountain fortifications in front of the Dingbei Army have been captured by us!" ”

The exhaustion on Kuropatkin's face disappeared instantly, and he asked in surprise: "The bunkers and bunkers of the mountain fortifications have been occupied?" Did the passages inside those mountain fortifications be occupied? ”

The staff officer nodded and said: "So the bunkers and bunkers, except for the ones that were blown up, the rest have all been occupied by us, and the passage inside the mountain fortifications of the Dingbei Army, our army has also entered it from the entrance where the bunkers and bunkers are connected to the internal passage of the mountain, and now the 8 mountain fortifications have completely fallen into the hands of our army." ”R1152
