Zhang Xuewu was not surprised at all that the defenders' fierce light weapon fire had caused him to hit the south wall hard.

Zhang Xuewu admitted that this tactic was quite effective, and whether it was during the War of Resistance against Japanese Aggression or during the later period of the War to Resist US Aggression and Aid Korea, many wars proved that as long as there were enough artillery strikes and more than 30 percent of the enemy's casualties were given, the enemy's will to resist would be reduced and weakened, and even collapse and abandon the position.

It can't be said that there are no cases of stubborn defense, but after all, those who can only be individual special existences, not even a few, flesh and blood people, not soldiers made of steel, meaningless advocacy is a kind of irresponsibility, and the greatest irresponsibility for the bloody and sacrificed soldiers.

In the war, it is the ordinary people who are displaced and separated from their families and the most people who die, and the children of ordinary people who enlist in the army and participate in the war are the most people, but when facing the Dongying Japanese who are selfless and undead, it is these ordinary people who pay heavy taxes, do not have enough food to eat, and do not have clothes to build a great wall of flesh and blood that saves the nation from perishing in the stormy waves.

Rumble! A grenade exploded near the railway line that was not four or five hundred meters away from the command, and the huge shock wave would instantly shatter all the glass of the girls' middle school. The artillery fire of the army seems to be starting to extend?

Zhao Xinyu waved Browning's horse card and greeted loudly: "Order all troops to enter the position!" ”

Under the sharp whistle, the Chinese soldiers dragged the Maxine heavy machine gun from the bunker to the machine gun firing position, and the troops began to enter the position along the communication trench.

"How long has the heavy artillery been extended?" Facing Zhang Xuewu's inquiry, Li Xinkai was slightly stunned, looked at his watch and said, "Eleven minutes!" ”

Zhang Xuewu glanced at the direction of the side ridge of Majiagou and said eagerly: "Immediately order Zhao Xinyu to withdraw the troops!" Fast! ”

"Huh?" Li Xinkai was stunned for a moment, he failed to comprehend Zhang Xuewu's intentions? Zhang Xuewu obviously didn't have time to explain anything to him, he dragged Li Xinkai away with his hand, and as soon as he picked up the phone, he heard a rumbling cannon sound from the direction of the side ridge of Majiagou, and the phone in Zhang Xuewu's hand suddenly slipped to the ground.

After pacing around the sand table a few times, in the deafening explosion, Zhang Xuewu said with a resolute face: "Order the first battalion of the reserve to go to the front line of Majiagou side ridge for reinforcements, and Li Xinkai, chief of staff of the division, will sit in town to supervise the battle!" ”

Zhang Xuewu took a deep breath and said to Li Xinkai: "I can't be impatient after I go up, this is my negligence, I can't blame you, let Zhao Xinyu sit down steadily, Xiao Yue Ben has him to fight, and send a few teams out at night, give me a few tongues to come back, I want to know which unit is the opposite army and who the commander is!" Do you understand? ”

Li Xinkai nodded, put on a steel helmet and led the guard platoon to immediately rush to the side ridge of Majiagou, saying that the official tactical term of the army's artillery surprise attack is double artillery fire compound advance suppression, as the name implies, first use artillery fire to strike at the enemy, relax the enemy's reinforcements, destroy its fortifications and defense system, and hit the enemy's morale, and then extend the artillery fire, giving the enemy a false impression that the infantry is about to attack, and then use fierce artillery fire to destroy a large number of killing and wounding the enemy's living forces.

This tactic is not worth mentioning in later generations, and this tactic first created and used by the Americans in the Battle of the Marne in World War I can only suppress firepower and provide sufficient support for the technical arms, that is to say, it is a tactic of the so-called rich people.

Compared with the strength and firepower, Zhang Xuewu's new First Division is an absolute first-class unit in terms of training, civil engineering, light firepower, and morale, but in terms of technical arms, Zhang Xuewu only has a 75-mm mountain field artillery, not a howitzer of more than 100 mm, let alone a 150-mm field heavy howitzer.

So Zhang Xuewu can't afford this tactic! However, Zhang Xuewu thinks that he can't afford to play a few times, that country where men are so poor that they can't even wear pants, how many shells can they transport with their capacity? Can you wipe Chengde City off the face of the earth?

If it was the US army that attacked, Zhang Xuewu would have launched a decisive raid at night until the last soldier, because the Americans had so many shells that they bombarded Chengde to Mars, but he himself couldn't, they didn't have that background, and sure enough, ten minutes later, the artillery fire of the Yue army extended again.

Even if there was only 10 minutes of fierce shelling, the first and second lines of defense on the front line of the Majiagou side ridge could be described as a mess, and the Maxine heavy machine guns that had almost become parts, the machine gunners who were blown into small pieces, the soldiers who were shocked to death in the artillery holes, the fortifications that had been rested and repaired were completely destroyed after only the second artillery bombardment by the army, and the corpses that had been piled up into the fortifications were blown out again, and this time they were all broken to the point that they could not be put together.

This is the power of heavy artillery? The surviving Chinese officers and soldiers looked at each other, to be honest, the shelling of the mountain artillery of the army was also very fierce before, but the brave veterans still dared to stare at the artillery fire to hit their own cold guns, but this time it was different, a crater was at least four or five meters in size, and it could blow up the hard frozen soil into a pot-bottom-shaped pit more than one meter deep.

The surviving Chinese officers and soldiers supported each other and shouted to set up defenses, but the infantry of the Yue army still did not attack, and the heavy artillery of the Yue army was not carrying out the earth-shattering artillery bombardment!

Majiagou side ridge! Monk Guanfeng was subjected to organized artillery bombardment by the Yue army! Zhang Xuewu drew two arrows on the map with a pen, could it be that the army was preparing to attack two support points at the same time? Or attack three support points at the same time? The commander of the army who can plan to use double artillery fire to advance and suppress must not be an idle person? Could it be that the inside of me is not an iron plate? Or are they also suspicious of each other in order to be able to win the battle?

It must be so, Zhang Xuewu breathed a sigh of relief, he knew that the attack of the Yue army would definitely be around four o'clock in the morning, because that time was the time when the human body's biological clock was the most tired and sleepy, and it was the most suitable time for the Yue army to be ready for work to enter the assault, so the first half of the night was destined to be extremely lax.

The army attacked two or three support points at the same time but made Zhang Xuewu breathe a sigh of relief, because doing so the army was equivalent to dispersing their attack power and sustained power, and the defenders' infantry light weapons firepower occupied an absolute advantage, once the army attacked and approached the defenders' positions, then the army's heavy artillery could hardly play a role, and the life of a heavy artillery was only 210 rounds, if the full charge was fired, this life would be reduced, so, according to the life of the gun barrel of the army, Coupled with the logistical supply methods of the Yue army and the route from Jinzhou to Chaoyang and Chengde, it is difficult to guess the amount of ammunition carried by a heavy artillery combination and brigade of the Yue army.

In the direction of Seng Guanfeng, the army used double artillery fire to advance and suppress the tactics, and the main peak and the two wings of Seng Guanfeng could only place a maximum of three companies at a time, so the casualties of Wang Chuang's second regiment were not large.

Zhang Xuewu immediately ordered all the officers and soldiers to rest immediately, enter the position at 3 o'clock in the morning to defend and guard, if the army attacked, the army would be put into 50 meters before it could fire!
