The collapse of the southern front of the Russian army was so fast that almost everyone could not have imagined. In just 3 days, the entire Southern Front Army of nearly 80,000 paper troops was completely swept away, if the first two days of the two sides were still fighting, then the last day was basically to pack up the prisoners, under the attack of Ma Yukun and Peng Yi's troops, the remaining Russian remnants had almost no ability to struggle. The entire position was quickly disintegrated like an avalanche. Although there are certainly individual Russian troops that have not yet been eliminated, this is no longer harmful.

The only position at the rear was the core fortified area of Nebuchu City, although in order to save other battlefields, many small and medium-caliber artillery pieces in the Nebuchu fortified area were partially removed. But the large-caliber artillery is still there, and the strength is relatively stronger, including some elite units of the Russian army, a full 60,000 Russian troops and their subordinate units are stationed in this frontal width of 10KM, 3 to 7KM, a total area of not less than 50KM in the fortification area, here is the Russians' most rear, but also the largest fortress group, if the previous entire Russian army position is like a crab, after the Chinese Army broke its limbs and pliers, only this most rear, but the hardest shell remains!

It turns out that the Russians are still very talented in repairing fortifications and various defense facilities, and Sevastopol in World War 2 allowed the Germans to use their absolutely superior air force and artillery units to gnaw it for half a day? Don't you see that the defense line of the Kursk salient in the 2nd World War was a wave of armored assault that gave the Germans the most technical advantage and sank into the sand? And now, although Xu Jie's crossing has caused a lot of changes. But the Russians' ability to build fortifications has not changed!

When building the entire fortified area, the Russians spared no expense, in order to make your fortress attack and defend. A large number of heavy guns were specially brought from Europe, the most notable of which were the fortress guns that were converted from naval guns, because the Trans-Siberian Railway was finally completed, and due to the limitation of transportation capacity, the complete 10-inch 40L heavy guns could not be transported to the front line by rail, so these old goods turned out of the naval artillery warehouses were cut short. A 10-inch 20L heavy gun was made.

When the guns arrived in the Far East, they were placed in enclosed reinforced concrete gun nests. In order to ensure the firing range, these guns have a large opening at the top, and the guns generally have an elevation angle of 0 to 35 degrees and a horizontal angle of 60 degrees to the left and right. The entire gun was fixed on a ring guide. And it is equipped with a special loafer and conveyor channel, and the shells used are also standard 227KG naval gun shells. However, due to the decrease in the charge, the firing range of this gun was much weaker, only a little more than 10 km. However, the powerful shells were too damaging to the infantry and armored units of the group's charge. Now the tank does not say a direct hit. As long as the shells fall within 30 meters, the fragile tank can be destroyed. And the Russians even frantically made shrapnel for 10-inch guns! Each shell contains hundreds of shrapnel the size of a fist! Not to mention beating people with these things, it is not a big problem to kill the steel plate of the willow connection within tens of meters!

And in addition to these 10-inch guns, which were converted into howitzers, the Russians also had some 8-inch cannons. If the 10-inch short guns are to disintegrate the offensive of the Chinese Army, then these 8-inch 40L heavy cannons are to better suppress the long-range artillery of the Chinese Army, and the maximum effective range of these naval guns has reached about 15KM (of course, to deal with slow targets that do not move). And the extreme range is even longer. In order to further improve the design accuracy and firing angle, these guns were basically arranged in semi-open gun pits. During the battle, move from the hidden place to the bubble pool by assigning the pool. Moreover, in order to improve the shooting accuracy of these 8-inch cannons, the Russian army also specially placed rangefinders and solvers on the commanding heights of Nebuchu in order to unify the command of various artillery groups.

In addition to these mass killers. THE RUSSIAN ARMY HAS DEPLOYED NO LESS THAN 60 6-INCH CANNONS AND HOWITZERS, AND 120MM GUNS ARE PLACED IN FULLY ENCLOSED BATTERIES. These armor-protected and rotating guns can be fired both directly and in a curved manner. It is the great enemy of the artillery of the Chinese front. AS FOR THE 75MM, 57MM, 47MM RAPID-FIRE GUNS, THEY ARE SCATTERED AT VARIOUS SUPPORT POINTS. In addition to artillery, the Russian army also built a large number of machine-gun bunkers and diagonal positions, linking various support points into one. At the same time, coupled with the barbed wire and minefields on the periphery, it finally forms a super fortress! The Russians were so pleased with this group of fortresses that they claimed that even the whole of the Far East had been captured. The Russian army can also support more than 1 year with these fortresses! The fact that the Russian government still wants to fight when the defeat is assured contains the meaning of striving for a more decent ending through a relatively successful fortress defense war.

And now that the Huaxia Army has wiped out the Russian field corps in the Far East, and Nie Shicheng plans to see how long the Russians can support what they have worked so hard to come up with! The siege cones of the Chinese Army are ready to go! It is impossible to deal with such a fortress with a reasonable layout and operation for many years, and it is impossible to do it in a short period of time. At that time, Manstein fought for a long time in order to capture the fortress of Sevastopol, with absolute firepower superiority, and if it wasn't for the god of Dora's cannon to directly end the speed ammunition depot, maybe the attack time would have been longer.

What the Chinese Army now has is time and Russian army attrition, and the field troops still need time to enclose land anyway. Although the fortress of the Russian army is well built, there are still some loopholes. For example, the Russian 8-inch cannon battery was a little too far away, and in order to extend the range as much as possible, most of the 8-inch gun positions were between the second and third lines of defense. And almost all the fire control rooms are chosen on artificial heights, and these abrupt heights are simply the best artillery landmarks in the eyes of the Chinese Army! Moreover, compared with the Russians, the biggest advantage of the Chinese Army is that it has airships to assist in the war, and these airships equipped with radio and simple observation equipment can transmit the shelling situation to the command headquarters in a timely manner.

Because indirect shooting can be realized, the train artillery unit of the Chinese Army does not need to be exposed to the Russians' guns at all, and the 12-inch 40L train gun is a pure naval gun. Longer range and more firepower. The artillery was hidden behind high ground and various shelters, and the Russians simply could not make accurate observations, let alone long-range shelling. The Chinese Army, on the other hand, can use airships to correct the shelling. Therefore, the first thing Nie Shicheng had to clear was the 8-inch gun position that was relatively outward.

As for the powerful 10-inch howitzer guns, because they are relatively strong and relatively inward. Therefore, it can only be blown up slowly, and at the same time, the lethal effect of these 10-inch guns can be reduced by releasing smoke. The larger number of 6-inch cannons and howitzers was handed over to the 8-inch cannons of the Chinese Army to deal with, and the protection of these guns was much worse, and there should be no problem with reinforced concrete armor-piercing shells weighing 150 kg.

AS FOR THOSE SMALLER CALIBER 120MM GUNS AND 75MM RAPID-FIRE GUN BATTERIES OR SOMETHING. The Chinese Army handed over the 6-inch cannon to deal with it, and these big killers, which also came from the naval guns, were mounted on a cross-shaped gun mount, which was very stable and had a long range. MAYBE A 45KG ARMOR-PIERCING SHELL WILL NOT BE ABLE TO DESTROY THE OPPONENT'S TURRET WITH ONE SHOT FROM A DISTANCE. But it doesn't matter, the Huaxia Army has time, and if one cannon doesn't work, ten cannons. Constant shooting is still useful after all.

In the operational planning of the Chinese Army, the first thing to deal with is naturally those 8-inch cannons with a long firing range, and for this reason, the Chinese Army will use three days to concentrate on the 12-inch and 10-inch train guns for bombardment, and even if they cannot be completely destroyed, they will all be disabled. Subsequently. The 8-inch and cannon guns of the Chinese Army will attack the Russian support points and core fortifications at the front. Then there was the close-range fire of the 6-inch cannon. and set up forward artillery positions to launch a concentrated attack on one of the points.

While the forward artillery is slowly knocking on the opponent's defensive line, the train artillery unit of the Chinese Army cannot be idle, they will suppress the 10-inch howitzers of the Russian army, and attack the trenches and tunnels in the direction of the breakthrough in order to block the support of the Russian army. And after the main fortress has been swept away, a large number of self-propelled infantry guns and heavy mortars will cover the attack, not requiring how fast but requiring no grass to grow in the passing! It takes a lot of patience to clean every corner.

Some people may say that this style of play is simply too slow, too old-fashioned, too uninspiring. This is still a helpless thing, the conditions were like this, how can you face a fortress with sufficient supplies and not grind it slowly with heavy artillery? You're going to say Manstein in World War 2. Well, in addition to heavy artillery, there are hundreds of aircraft, and the final result is still slowly grinding. Facing the offensive and defensive battles of this costly fortress. God can't help it. Then you can only play slowly. Attacking a fortress is either filled with lives (not necessarily enough) or with artillery, and if you can't fill it, you don't have enough firepower. If you can't do it, just don't fight! Clever calculations do not play much role in the face of impregnable walls.

However, before setting off, Feng Ru, the captain of the Huaxia Air Force in charge of the airship, suddenly put forward his own opinion, whether the target wind, which could not be taken care of temporarily during the attack, could be suppressed by throwing incendiary bombs and smoke bombs? The Russians basically have no anti-aircraft firepower, and because of the supplies, there are still a large number of wooden houses in the city of Nebuchu, and many bunkers are also mixed brick and wood structures, if you throw gasoline bombs mixed with sulfur and rubber, these things will cause great damage to the wooden buildings of the Russian army, and even if you can't destroy those well-defended artillery nests, at least the smoke caused can affect the observation of the other side, right?

"It doesn't seem to be very reliable." Nie Shicheng looked at Feng Ru's report and said to himself, after all, the current airship is not the Zeppelin of the 1st World War, the largest is more than 200 meters long, and there is not so much load, and more importantly, if this thing is thrown down a few kilometers, God knows where the Dao bomb will fall! An offset of a few hundred meters is considered light. Moreover, there are not many airships in the Huaxia Army now, excluding those used to provide artillery shots, at most a dozen.

But after thinking about it, since the airship is idle, why not find it if you can make some trouble for the Russian army? And now I have a lot of fuel left over here for the manufacture of flamethrowers. In addition, the Huaxia Army still has some doubts about the use of flamethrowers by individual soldiers, so after thinking about it, Nie Shicheng felt that it was still good to make bombs with these incinerants that were originally intended to be contained in flamethrowers. What I didn't expect was that what Nie Shicheng did unleashed a demon!
