The battle started quickly and ended quickly, and when Lao Zhao returned to Qiqihar with the army of horses and ploughs, there was no movement at all.

Although his division did not experience the fire, and also lost all the cadres from the division commander to the company commander, they saw the battlefield that touched their nerves at the beginning of the year, which was different from the sound of guns and cannons heard in the distance, they saw the mess all over the ground with their own eyes, and felt the bloody scene in person, especially they also carried a batch of guns and bullets, not only were they not depressed, but they were excited, they had a goal, the goal of the battle was to fight such a winning battle, although there had been a victory in Jiangqiao before, But the scene was nowhere near as good as it was here.

They didn't care why Lao Maozi would fight, anyway, they knew a little bit, fighting with their ally advance army, then Lao Maozi should be beaten!

Press Lao Zhao to lead the team back to take over the troops, Dong Ku is busy with the love of the materials quickly transported to the designated location to hoard, and all the cannons are disassembled and transported back to Harbin for transformation, these cannons are too bulky, not conducive to long-distance transportation, not conducive to mobility, so, before he has the ability to build large-caliber artillery, he still needs to use these cannons.

And those 75 mountain artillery and field artillery, he also withdrew from the top of the Hutou frontal fortress, and when it was mortar, he did not move for the time being. Although he judged that Soviet Russia might not attack again, he had to guard against it, because the tank bombardment on the river embankment could not be solved, and the other side might take advantage of this opportunity to launch an attack.

He did not leave the tiger head in the tight transportation of materials, he remotely controlled, let the oil drilling team under the protection of the Flying Tigers, drive to a specific location, and start drilling at two points a few miles apart.

At this time, he can already work in the field, although it is hard, but he needs time. He had to dig the wells before they were opened, in May, and after checking that there were no problems with the pipelines, he would backfill them. Otherwise, once civilized, it is all water. And it will collapse, and if there is a problem with the pipeline, it will not be easy to solve at all. The most important thing is that after the weather is warm, the Japanese planes will fly as usual, and they will frequently reconnoiter the defense here, and oil wells will be discovered.

Drilling, Dong Ku has been preparing for several months, and he is very confident, because. At present, there is no good way to solve the shallow gas problem in the world, except for the use of heavy mud to kill the well, before the blowout appears, there is no very effective means of prevention, once the blowout, it is often the machine crash and the death of people, drilling failure.

However, Dong Ku gave the approximate parameters of the blowout preventer that could be achieved by the current technology during the Cold War to Jewish scientists, and they studied and produced it in a few months. After the final BOP came out, it blew out. As long as it's not too stressful, it's fine.

And Daqing Oilfield is different from the ocean, the shallow gas pressure is not so great, although there are blowouts at the beginning of exploitation, but the danger is not too great, with the help of blowout preventers and advanced drilling experience. Casing, cementing, will be formed in one go, and all processes should be completed and oil produced within a month.

After all, there is no need to survey specific oil production sites here. The geological structure is also stable, and the depth of the oil layer does not reach 3,500 meters, only at a depth of about 2,000, plus those skilled workers, there is no big problem in succeeding at one time.

Once the two wells are completed and the drilling equipment is hidden, the supply of oil will be able to meet the few mechanical needs of the advance army at present, and it will be able to ensure that Dong Ku fights a large-scale mechanized war. And those ancillary products will also solve the various raw materials that Dong Ku currently lacks, so that his industrial system can develop rapidly.

In addition to arranging the start of drilling, he also gave the industrial park a plan to transform the Soviet Russian artillery to facilitate maneuvering, reduce the weight of the artillery while the caliber remains the same, and install wheels to facilitate the towing of trucks.

He wants to complete his next goal and lay the foundation for the accumulation of force before he is civilized, when the ground can still carry heavy loads.

When he was busy, the Soviet Russian army did not stand still, he was not worried about superfluous, and the bearded man was not willing to lose, and in the days near the opening of the river, he was going to attack again.

In one day, the reconnaissance team that remained in Soviet Russia was constantly being steadily pressed in, and the Russian army rushed back and had retreated to 'Dalenevchensk'. And the Soviet Russian troops once again recaptured the ruined 'Izbesk' without bloodshed.

Here, the artillery of the fortress cannot be attacked, and in defense, it will not be passive, although it is more than ten kilometers away from the offensive position, but for the movement of the army, more than ten kilometers is not difficult.

This time, the Soviet and Russian troops did not attack rashly, they assembled in 'Izbesk' and waited for the arrival of the newly appointed General Skoinovich.

The tanks, which were originally rushing here in a steady stream, were only heavily damaged because Fei Lei took over the Tiger Head Fortress and pulled out the camp in advance, but the follow-up transportation did not stop. As for the destroyed railway, the roadbed was not damaged, and the track was paved and it was finished, which did not affect it too much.

This time, the Soviet Russian troops did not use soldiers to attack on foot, they had to use cavalry to quickly approach the fortress pillboxes and destroy the forward positions, so that as long as they were stuck, the mortars on the top of the opponent's hill would be useless.

After receiving the rapid pressure of Lao Maozi's army and gathering in 'Izbesk', Dong Ku also felt a lot of pressure.

His only solution at present to the army was to intercept them with artillery on the river and on the opposite bank, but without the command of the observers, with the help of fixed elements, although they could cause damage to the Soviet troops, they could not prevent them from approaching the embankment. And defending the embankment, even five guns will not be able to solve all the enemy's artillery positions in 'Izbesk', and the embankment will still be a grave covered by the enemy's artillery. The riverbank defense line without cement bunkers, guarding there, there are not enough people to fill it.

The speed of the Russian army's build-up far exceeded Dongku's expectations, and after the reconnaissance team was gradually compressed back to 'Dalenevchensk' by the army, and then forced to return to the river bank, or away from 'Dalenevchensk', the Tiger Head Fortress entered the tense atmosphere of battle again in the twilight.

The bearded man gave up the inconvenient Rao River with an iron heart, directly attacked the tiger head, and was ready to attack the three-way pass at any time. Both entrances have roads that allow for the rapid movement of large armies, and although the cost is not small, the effect is certainly the best.

Dong Ku and Xing Yuan's high-level executives discussed in the conference room to see how to solve the current problem. It is obviously not the best strategy to go out to meet the enemy, and it is not easy for them to do anything with this little force.

But once the enemy's tanks approached the river bank again, that. It will be difficult to defend the other day, and once the number of tanks on the other side is sufficient, the concrete bunkers on this side will not be able to block the casualties at the firing port, and it will be very easy for the enemy to get closer.

But they studied for more than half an hour, but they couldn't come up with a specific plan. At that time, the reconnaissance team on the front bank of the river sent back the news, and the enemy tanks had indeed entered the field.

After receiving the news, Dong Ku didn't bother anymore, and directly ordered: "Don't care about the follow-up first, let's just hold on, and leave some of the tanks on the river first!" ”

"Yes!" Pan Mazi left the command headquarters after receiving the order, and with it, the artillery of the fortress roared.

The shells tore through the night that had just fallen, and fell on the river in pieces.

The roar of the tanks was drowned out by the whistling shells. Ten rounds of dropping, even if the density of the tank is not large, it will not be able to withstand the devastation of effective shooting.

With a loud bang, fireworks lit up on the river, and the blazing fire provided a convenient view for the reconnaissance team in the distance, and then more accurate shells fell around the fleeing tanks, and the air waves generated by the violent explosions overturned the moving tanks. It's as easy as tipping the table.

Dozens of tanks entered the river, in a violent explosion. Only a few lucky ones resisted the shock wave and climbed the embankment with difficulty in the crater, and then took control of the embankment.

The bombardment of just five minutes lost more than 20 tanks in the first wave, and also let the Soviet and Russian troops who came later see the ferocious firepower on the opposite side.

A major general in charge of the temporary command received the other side to intercept the river, and the tank suffered huge losses. After the report that it was not easy to pass, he did not hesitate too much, and directly ordered to enter the ice along the blind spot of the artillery, close to the front of the fortress on the river bank, and avoid artillery fire.

Really. This trick made the fortress's artillery useless, and the shells could only fall a hundred meters below the river embankment, which did not pose a threat to the tanks close to the river embankment, and in less than an hour, the long line of tanks gathered at the designated position.

Although Dong Ku had the opportunity to intercept with an iron fist in the middle, he still gave up, because in that case, he would fall into the encirclement of the infantry moving with the tank, and go, it would be purely a death squad, and it would not be worth it.

Unable to prevent the tanks from entering the embankment, Dongku did not stop shelling, but the fortress artillery had stopped, no longer making unnecessary waste, and did not bombard 'Dalenevchensk' in the distance. There, at present, there is no large army stationed, and the shelling is only a scattered small group of enemies, which is worthless.

After the fortress artillery lost its effectiveness, Dong Ku ordered the mortars on the top of the hill to bombard intensively, so that the tanks could not pad the wood, kill and injure the infantry who followed, and let the tanks stay on their own at the river embankment.

With the whirlwind of sobs, the shells fell densely on the embankment, and although it could not cause direct damage to the tank, the explosion was enough to shock the tanker that he did not even recognize him.

In the dense roar, the tanker was like riding a roller coaster, bumpy, knocked on his head and bleeding, bruises all over his body, and it can be said that he could not be relieved of his suffering.

The infantry who followed were unlucky, they were not protected by an iron shell, so they naturally could not withstand the bombardment of shells, and in the explosion, countless stumps and broken arms flew all over the sky, driving them back into the blind spot of the shells on the river embankment, watching the fire flickering in the distance, except for praying for the tankmen inside, nothing else could be done.

After more than ten minutes of intensive bombardment, only one tank was destroyed, and the others could still move in the explosion.

After receiving the report from the reconnaissance team, Dong Ku ordered the bombardment to be stopped. You can't blow up the tank, and even if all the people inside are killed, you can't stop the tank from shelling, and the shells are wasted. Besides, Dong Ku is not willing to waste these shells now, after learning that the army of dogs and eggs exceeds 100,000, he has already formulated the next battle plan, and the shells still need to be used.

The Soviet and Russian troops did not stop moving because of the continuous shelling, and after confirming that there was no shadow of the advance troops around, in addition to occupying the river bank, tanks were still being transported to the river embankment. With the roar of the motors, the tanks climbed to the predetermined position.

And under the river embankment in the distance, the Russian soldiers could not climb the steep cliffs, but they could not easily attack them in the dark, these Soviet Russian soldiers were at the position of the tank approach, piles of wood were ready, and when the enemy's shelling stopped, they quickly laid the wood and adjusted the elevation angle of the tank gun.

After Dong Ku stopped for more than ten minutes, he ordered another bombardment, and asked Pan Mazi to be ready to evacuate the artillery on the hill at any time.

After four rounds of shelling in a row, more than two hours later, the tanks on the embankment roared.

The shells landed on the mountainside and exploded with a bang, which also indicated that the Russian tank station was stuck and could return fire.

Dong Ku did not hesitate and directly ordered the withdrawal of the mortars on the top of the mountain.

He did not regret giving up the fighter plane that attacked and destroyed the tank on the river embankment, he was not willing to increase casualties during this period, and the battle had not yet reached the stage of desperateness, so he decided to use machine guns and bullets to crush the attack on the opposite side, as long as he held it for three or five days, the ice would crack.

The Soviet and Russian tanks that were standing on their heels began to adjust continuously, and some of the tanks were already roaring, and then the shells fell on the top of the mountain, so that the mortar positions that were still dense just now were frequently fired, and the few remaining trees were torn apart, turning the mountain into a bald mountain.

Violent explosions continued in patches, and the soldiers in charge of holding their positions and supporting the fortress began to prepare.

The barbed wire fence at a distance of 100 meters in front of it, even if it is torn apart by artillery fire, still has the effect of interception, and besides, under the dense barrage, it is difficult for the enemy to get closer.

This time, in the gun holes of the fortress bunker, in addition to making the necessary cover for the snipers, all the larger shooting holes were made of Soviet-made Makqin as pig's feet, and those Depp retreated to the second line, so that the possibility of being hit by stray bullets and shrapnel in the bunker was minimized.

The Russian tanks continued to converge along the dead ends of the fortress guns in the roar, and at about ten o'clock, the entire embankment had exceeded 500, and the number was still growing.

Dong Ku received the information that the reconnaissance team ventured closer, and he knew that there might not be an attack tonight, but tomorrow, it must be a bitter battle.

Thousands of tanks?

He frowned and pondered. Unable to stop the other side from approaching the river embankment, the mortar will have no place to stand, the mountain artillery has been withdrawn and transported, and tomorrow, there will only be heavy machine guns and 75 anti-aircraft guns to resist the attack.

To put it humanely, Dong Ku is absolutely sure that even if Soviet Russia invests a million troops, his ammunition reserves are enough to ensure the uninterrupted shooting of thousands of Makqin.

But the bombardment of the tank is annoying, and if the tank cannot be solved, the attack can never be contained.

Although he sent troops to guard the steep place, it was limited to defense and attack, and he looked weak.

Is there no way to get rid of the tank on the opposite side? That's tens of thousands of tons of steel!

What Dong Ku lacks most now is steel. (To be continued......)
