The second shell landed outside the cannon nest, and the slender body cut off a corner of the reinforced concrete cover outside the cannon nest like a sharp sword! After the explosion, the cannon nest collapsed by one-third, and dozens of Austro-Hungarian soldiers who had not had time to run out were smashed into a ball of meat paste.

The real fatal thing was the third shell. This shell hit the top of a 210MM heavy howitzer. The concrete cover with a thickness of 1.5 was as vulnerable as tofu! The shell left a diagonal perforation on the top, and then directly hit the 210MM howitzer ready to fire in the cannon nest! The artillery weighing nearly 10 tons was instantly blown into pieces, and a wave of fire spread around and ignited the launching medicine next to it. Two minutes after the hit, a violent explosion sounded throughout the battlefield. A column of dust nearly 100 meters high rushed into the sky like a volcano erupting. When the dust dissipated, the cannon nest as high as more than 3 meters had been wiped out from the ground, leaving only a huge crater! A whole company of soldiers and their artillery turned into ashes!

When the large-caliber artillery was almost bullet-biting and the knife was bleeding, the medium-caliber artillery surrounding the Lviv Fortress was also fighting. Compared with the suppression of the Russian army's large-caliber train guns, the Austro-Hungarian Empire had a certain advantage in the fight between the medium-caliber artillery group. First of all, because the Austro-Hungarian army was the first to take the lead. The 3-inch gun deployed by the Russians at the forefront directly led to the decline of the Russian firepower. Although the 122MM and 152MM howitzers behind were outside the range of Austro-Hungarian heavy artillery, their power was too small and they were not lethal enough for the Austro-Hungarian artillery hidden in the artillery nest. Although the 107MM artillery fired fiercely directly, they lacked the shooting range. After knocking off several bunkers and machine gun bunkers on the outermost side, they could only stare at the target behind the wreckage.

The firepower suppression of both sides lasted for 4 hours. During this period, the number of shells consumed by both sides exceeded 150,000. This number is very amazing even on the current Western Front. After all, the Western Front has not finally stabilized... Then this is just the beginning. The Battle of Lviv can even be the first large-scale attack on the fortification area in Battle 2. Both sides were not well prepared for this battle. In the remaining time of the day, although the large-scale attack composed of hundreds of artillery artillery stopped, the competition between the small cannon group and the heavy artillery never stopped, and there was almost no minute on the battlefield! With the help of the reconnaissance aircraft and observation posts of both sides, the long-range heavy artillery kept repeating the process of searching for opponents and destroying opponents!

In addition to the large-scale artillery battle between the two sides of the Lviv Fortress Area, the Russian army also launched an attack on the two fronts to the west and east of the fortress area. Although the fire density and artillery level are incomparable to the fortress area, it is also the first time for Russia and Austro-Hungary! In the field environment, the Russians concentrated 50 manned artillery and 20 trench guns on a one-kilometer front for fire preparation for the first time, which was simply the first time for the Russians, so it was very easy to break through the surface positions of the Austro-Hungarian Legion.

The Russian army on both wings obviously implemented Borusinov's idea of ​​rapid advancement by multiple breakthroughs. The 11 breakthrough points on both wings were all equipped with firepower no less than that of an artillery division. At the same time, the elite infantry was used as the pioneer and rapid-fire guns were approaching support to make breakthroughs. After tearing the gap open, the cavalry division entered one after another, expanded the gap and advanced in depth.

Unlike the thunderous fire preparations when attacking the fortress, the fire preparation time for field breakthroughs is relatively short, generally at most 40 minutes, and the firepower extension will not be very far. After all, there are not so many long-range artillery, just clean up the visible ones. Most Russian cavalry launched an attack after 20 to 30 minutes of fire preparation. They successfully crossed the unmanned land in front of the front line, and then crossed the trenches and outer bunkers. And rushed towards the depths, the Cossacks waved their sabers and rifles, followed by horse-drawn machine gun vehicles, towing artillery and even a small number of truck guns.

However, just when the Russians were making quite smooth progress, the fire-restorming of the Austro-Hungarian Legion also surprised the Russians! At some breakthrough locations, the Austro-Hungarian Legion concentrated a large number of self-propelled artillery to block them. These artillery placed on the territory of trucks or cricket tanks are expensive, but they are worth the money. Their mobility greatly compensates for the lack of range. When the Russians moved towards the breakthrough, these artillery quickly changed their positions, and at the same time, under unified command, carried out a brief but fierce fire attack on the invading Russian army through radio!

When a few small black dots appeared not far away, the Russians didn't care. They continued to move forward, but arranged the warning of a small group of troops. After a moment, the Russians regretted it. On the flank of this cavalry regiment, the four 150MM heavy infantry artillery secretly came over under the cover of an infantry company, and then they used 50KG high-explosive bombs to make the Cossacks suffer a little less than 3,000 meters!

The shells fired by something smaller than ordinary howitzers and whose range is closer than ordinary howitzers are at the same level as ordinary howitzers! Suddenly, a 45KG shell exploded on the ground with huge pits of about 1.8 meters in depth and 7 meters in diameter! The preset shrapnel even caused a storm-like iron rain above the cavalry's heads! The originally neat formation was completed by several stages of artillery fire.

This is just the beginning. The 75MM rapid-fire gun, 105MM howitzer and a small number of 150MM howitzer attacked the target from different angles and distances. Although the firepower was not very powerful, the strike accuracy was very good. Under the correction of the reconnaissance aircraft overhead, one round of shells fell accurately in the middle of the cavalry queue, breaking up the marching corps.

The limited number of artillery with a long range aimed at the logistics units behind the cavalry. These large carts pulled by double horses are the key to the Russian cavalry's continuous combat capabilities. On the open field, carriages were destroyed by flying high-explosive bombs or incendiary bombs. After only more than forty minutes of interception and shooting, the cavalry division may take two hours to re-collection the troops, and it takes half a day or even a day to wait for the arrival of subsequent supplies to continue to attack.
