The bombardment of large-caliber artillery is difficult to avoid, especially the uninterrupted artillery in a narrow area, which is not something that people can avoid. Unless they hide in tunnels that are dozens of meters deep, there is no possibility of surviving. Unfortunately, the Red-clothed Country was comfortable for decades, and the domestic government enjoyed peace for too long and had never had such thoughts, so there was no underground tunnel in Madrid.

Madrid announced the conquest, but it was not the time to rest. Cai Songpo took a little rest and left Liangbi to command the heavy losses to clean up the battlefield and eliminate the remaining enemies. He led the fourth Japanese army division and the Hualan Tank Division to help the Second Japanese army division that defended Piedraita.

Cai Songpo made such a choice not because he favored one and deliberately did not support the Condor Legion. It was because he learned from the telegram that after entering the air force, the Condor Legion had stabilized its front line and had no danger of being broken through for the time being. However, after the fighter regiment of the Golden Dragon Legion fought with the Red League Air Force and suffered a loss, the position of the Second Division of the Japanese Army was already in danger.

The Second Division of the Japanese Army, with a number of less than 20,000 people, was inevitably injured when the equipment was at a disadvantage. The Japanese Army is worthy of being a tough army, but it still did not collapse after losing more than 8,000 people. Not only did they not lose their will to fight, but instead used night battles to fight with bayonets to regain the lost positions during the day.

Voroshilov was also surprised at the resilience of the other party. These mercenary troops, which were not the main force of the Hualan Army, actually had such combat capabilities. Originally, in his thoughts, only Red United soldiers who were armed with utopianism would be ready to die on the battlefield. However, the battles these days have shaken his idea.

Perhaps this is the most elite unit among the Japanese mercenaries. Marshal Voroshilov could only comfort himself in this way. When a commander who always relies on the courage and numerical advantages of soldiers and uses a large amount of sacrifice to win, he suddenly found that the enemy in front of him was more sacrificed and less afraid of death, his inner shock and confusion were indescribable.

There was a vague premonition in his heart that Marshal Voroshilov decided to gather the strength of the entire army in the early morning of tomorrow to break through the opponent's defense line in one fell swoop, and to completely eliminate this tenacious enemy army on the position. After making up this idea, Voroshilov immediately arranged the order of attacks for the large army.

At 3:30 in the morning, the regular night attacks of the Japanese soldiers had ended. The effect of the raids that night was not obvious. The Japanese soldiers only regained two lines of defense, and two lines of defense were occupied by the opponent. According to Marshal Voroshilov's calculations, as long as the entire army launched a charge, it only takes half a day to wipe out the entire Japanese army.

At four o'clock, the Red Alliance began to quietly enter the position, and a large number of searchlights were arranged to the front line. All T26 tanks and BT5 tanks were neatly arranged to the forefront, preparing to launch a general attack on the Japanese position. The artillery was prepared in the dark. In order to facilitate rapid shooting, the artillerymen piled shells onto the artillery position.

The general attack time was set at six o'clock, and all the Red League troops were preparing in an orderly manner, waiting for the general attack time to come. However, these Red League soldiers did not notice that not far from the frontier position, an extremely large telescope was quietly staring in this direction.

This telescope belongs to the direct reconnaissance company of the Hualan Tank Division. At this moment, the platoon leader Wang Dong was nervously observing everything on the position. The reason why he was able to use a telescope to observe the enemy's movements in the dark was because his surprisingly large telescope is also one of the new equipment to be put into battlefield testing, the infrared night vision telescope.

The infrared night vision telescope is the same as the infrared night vision device specially equipped for special forces. It uses infrared rays that are invisible to human eyes to project this light and then use special lenses to receive reflections to achieve the purpose of seeing the enemy clearly. Although the scenery in the lens is red, it can see the movements of the enemy in the distance.

After ten minutes of viewing, Wang Dong could already determine that the enemy was preparing for a large-scale night attack. The news was quickly passed to the command center. Cai Songpo immediately ordered the Air Force to take off a modified H-2 bomber for reconnaissance. This guest reconnaissance aircraft also has infrared night vision equipment. After idling around the opponent's position, it quickly grasped the deployment of the enemy and took photos with a special infrared camera.

After the plane landed, the photos were washed out and quickly sent to the staff, which were identified by the aviation staff. The deployment of the enemy troops was marked on the map one by one and sent to the headquarters and artillery units. Cai Songpo knew that time was not waiting for anyone, so he immediately ordered the entire army to prepare for attack.

At 5:40, the Golden Dragon Legion had made all preparations for attack. The large-caliber artillery pointed the muzzle diagonally towards the sky. According to the standard position and distance in the photo, the pitch angle was calculated and the order to fire a single shot was waiting. After learning that the troops had completed the combat preparations, Cai Songpo announced the order to launch an attack.

At this time, the Red Alliance had already taken their place and prepared for the upcoming general attack. They did not expect that before the order for the general attack had arrived, the Golden Dragon Legion's artillery shells had arrived. Artillery of various caliber began to fire at the same time, especially the Red Alliance's artillery positions, which were specially taken care of by large caliber howitzers.

The Red United artillery soldiers who piled shells next to the cannons for convenience finally tasted the bitter fruit of underestimating the enemy. When the Hualan Army's shells fell into the piles of shells, they immediately caused a chain reaction. The violent explosion made the dark night sky red, and the artillery positions of the Red United artillery positions in just ten minutes were completely wiped out.

The Red Alliance on the frontier positions was not much better. In order to attack, all the equipment was moved to the ground, and the troops were gathered outside the positions and ready to attack at any time. As a result, dense shells attacked, causing heavy casualties and injuries to the soldiers.

Those light and thin fast tanks are also not immune. In order to increase speed, both the T26A tank and the BT5 fast tanks have reduced their armor. As a result, even if they were hit by a six-digit mortar, these tanks were completely destroyed.

Under the baptism of dense shells, the front positions were completely covered, and violent explosions came one after another. The group of tanks that were arranged neatly and majestic just now were immediately blown into a pile of scrap iron.
