The scorched earth of rubble and scorched earth continued to roar down from the sky, and soon the long section of the main attack was like the surface of the moon covered with countless craters of different sizes, textures, and depths, and the sky rolled, suspended, and filled with a thick and suffocating smoke and dust, which poured out in all directions in waves, as if to swallow up the entire city and the besieging Chinese army......

The earth-shattering artillery preparations continued until the seventh hour, when all high-trajectory artillery temporarily ceased firing so that 60 light bombers, 120 heavy bombers, and 24 attack airships of the First Air Group could enter the battlefield and drop bombs.

Each ZH-2 "Yanlei" heavy bomber is loaded with 12,100 kg of light bombs, the QH-3 "Wind Thunder" light bomber is loaded with 4,100 kg of bombs per aircraft, the 12FTG-2 Ziyungai medium attack airship is loaded with 16 250-kilogram heavy bombs per ship, and the 12 FTG-3 "Qiangyungai" heavy # are loaded with 32 250-kilogram bombs.

Led by two large formations of light bombers, followed by three large formations of heavy bombers, and the last was the 4th formation of airships, with more than 200 units of various sizes slowly flying through the smoke-shrouded city of Ulan-Ude, densely dropping thousands of thick and heavy bombs that exuded a different evil texture and at the same time emitted a miserable whistling sound as if the hysterical screams of a virgin facing rape.

The target of this indiscriminate carpet bombardment was not the front-line positions of the Russian army, but the general bombing of the urban areas deep in the defensive line according to the instructions of the ground, with the aim of blocking the reserves in the city to support the front line and at the same time creating chaos. Further dampen the will of the soldiers and civilians in the city to resist.

In just a few minutes, the entire city was flooded with a glowing red light, and a thick cloud of smoke slowly rose from every street, showing a hellish look with impunity......

This time, in addition to the super-large caliber siege guns, all the field mortars from 80 mm to 210 mm switched to special smoke grenades with warheads painted with yellow circles, and concentrated on bombarding the front of the main attack area, very quickly. The choking yellow-gray smoke spreads into a hazy and magical ribbon over a narrow area of thousands of meters, and the smoke belt pushes towards the city center in the southeast by the breeze.

At this time, the Russian positions in the north of the city had long been unrecognizable, the three cement fortresses had been beaten into porous cheese, and some of the more than 30 rotating turrets on the four armored batteries had been overturned: = Thick fireworks were spewing out from several bullet holes with a diameter of nearly half a meter; Some of them are cracked or the tower is crooked or the barrel is blown up, and there is no longer no inaction; Others, despite being covered with bullet marks, still rotated freely, and kept firing counter-attacking artillery fire - the Russian soldiers inside who were protected from toxic smoke by the filtered ventilation devices would surely shout Long live France.

The infantry trenches in the open ground between the fort and the battery were almost smoothed, and the ground was blown up to half a meter high. The woods and wooden houses close to the defensive line were all burned to ashes, and dark red shrapnel that hissed and smoked and twisted and distorted was scattered everywhere. and bloody or scorched stump meat.

During the shelling, the command posts of the Russian army on the front line were basically paralyzed, and the communication between the remaining defenders on the front line and the city center command - including manpower communication - was also completely interrupted, and none of the 16 messengers sent to the front line by the command returned one after another.

At about 15:30, the sound of artillery gradually faded away, and as patches rang out, Chinese soldiers wearing smoke masks and looking like ghosts jumped up from a line of parallel trenches that were only 100 meters away from the obstacle area of the enemy's front line, carrying various equipment ranging from painkillers to 37 infantry artillery and rushed to the enemy position.

Looking down from the observation balloon hanging high in the air, I saw countless gray-green dots pouring out from one end of the cobweb-like criss-crossing Chinese position, merging into a small stream of intermittent and short water - that is, the commando. densely pounced on the front-line positions of the Russian army.

About a kilometer in front of the Chinese infantry in these assaults, the artillery barrage of steel chips, grenades and poisonous smoke continued to extend in depth......

The infantry assault was divided into several levels: the divisional assault was carried out by two regiments in front and two regiments as reserves; The first-line regiment had two battalions as the first echelon and one battalion as the second echelon. The infantry battalion formed four successive assaults on a frontal width of three or four hundred meters: the first wave was a small group of thirty or forty people. It consists of engineer, infantry and fire support detachments, equipped with submachine guns, machine guns, grenadiers and wired telephones, plus barrier-breaking weapons such as flamethrowers, blasters and tandem explosive projectiles. The task was to destroy obstacles on the offensive route that the artillery had not completely cleared, and to observe the effect of artillery projectiles in close proximity, and to direct artillery fire to suppress the remaining fire points exposed by the enemy. The second and third waves consisted of over-formed infantry companies carrying large quantities of grenades, and the fourth wave consisted of close fire support units equipped with machine guns, flamethrowers, light mortars and infantry guns.

Ulan-Ude was located at the confluence of the Selenga and Uda rivers, and there were thawed, fast-flowing rivers to the west and south as natural barriers, attached to the strong fortress batteries on the banks, and the strong fortress batteries on the banks were bound to suffer huge losses, and the 1st Army had to attack from the north and east.

In this section, four of the eight divisions of the group army were assembled, each division was responsible for an average of 1.25 kilometers of frontage, while only two divisions were assembled in the 5-kilometer-long auxiliary attack area to the east.

Based on the experience of the Asian-Russian War and the intelligence gathered before the general offensive, Xiao Lieri clearly realized that the Ulan-Ude Fortress, which was built with the most advanced technology in Europe, was completely different from the Chita Ring City position that was easily conquered before, and it must not be solved by a single round of artillery bombardment and a single charge.

The Chita Fortress, which had caused 70,000 heavy casualties among the Chinese and North Korean coalition forces, was completely razed before the retreat of the coalition forces, and was never rebuilt after that.

In front of him, this modern fortress, which is one of the three major defense cores of the Russian army in Siberia, has endured nearly 200,000 shells and thousands of bombs in just eight hours, and there is still a considerable amount of strength to counterattack the artillery positions exposed by the Chinese army.
