Hundreds of planes of the 15th Air Force and the 1st Air Force of the Japanese Army bombed for an hour, and at about 3 o'clock in the afternoon, the little devil planes stopped bombing.

In view of the fact that the continuous dispatch of Japanese air forces was likely to affect the operation, Sun Weiguo once again concentrated the anti-aircraft weapons scattered in various armies and left in the warehouse.

Previously, Sun Weiguo had set up an anti-aircraft artillery regiment, but the results were not very good, and the anti-aircraft artillery regiment could not maneuver and did not pose a threat to the Japanese aviation at all.

Therefore, after the expansion of the unit, Sun Weiguo directly canceled the establishment of the antiaircraft artillery regiment, and the regiment commander Zhao Lin was also transferred by Sun Weiguo to the combat unit as the regiment commander, and Zhao Lin is currently serving as the chief of staff of the artillery brigade.

Temporarily pooling the anti-aircraft weapons of various units, Sun Weiguo once again established an anti-aircraft artillery regiment, and he also brought Zhao Lin again to serve as the head of the anti-aircraft artillery regiment.

THE ANTI-AIRCRAFT ARTILLERY REGIMENT WAS EQUIPPED WITH 30 88MM ANTI-AIRCRAFT GUNS, 18 50MM ANTI-AIRCRAFT GUNS, AND 30 40MM ANTI-AIRCRAFT GUNS, AND AT THE SAME TIME, SUN WEIGUO TOOK OUT ALL THE 50 20MM MACHINE GUNS AND 60 12.7MM ANTI-AIRCRAFT MACHINE GUNS AT HOME.

After all, these weapons are dual-purpose, and they can be used as anti-aircraft weapons to fight the Japanese air force, and if they are placed flat, they can be used for flat fire, which is the best weapon for fighting small devil tanks.

However, in order to be able to take the Japanese airfield, Sun Weiguo can be regarded as having invested enough money this time.

The Seventh Division, the 1st Ranger Brigade, and the Anti-aircraft Artillery Regiment participated in the battle with more than 10,000 troops.

At 3:40 p.m. on 16 July, Sun Weiguo handed over the operational command to Chen Zhengwei, commander of the Honorary Seventh Division, and he asked Chen Zhengwei to command the Honorary Seventh Division, the First Ranger Brigade, and the Antiaircraft Artillery Regiment to attack the Japanese airfield and capture the Japanese airfield in the shortest possible time.

Chen Zhengwei gave Sun Weiguo an accurate time, and he promised that before 12 o'clock in the evening, the Japanese airfield would be captured.

According to Zhu Jianwei, chief of staff of the New Seventh Army, Chen Zhengwei has some understanding of the troops stationed at the airport.

After accepting the command, Chen Zhengwei immediately ordered the engineer platoons of the new 1st Regiment, the 2nd Regiment, and the companies directly under the 3rd Regiment to immediately start digging fortifications.

Three platoons of engineers, dozens of men, began to dig a communication trench near the starting position, these engineers had professional tools, and in a short time, they dug the communication trench.

With these communication trenches in place, Chen Zhengwei ordered the new regiment that was the main attack to immediately enter the communication trench, and after the officers and men of the new regiment came to the communication trench, their task was still to dig the trench.

Wielding shovels, the fighters quickly dug into the soil, connecting the communication trenches that dug directly in the direction of the Japanese airfield.

Because each regiment has a reconnaissance platoon, an engineer platoon, a baggage platoon, and other establishments directly under its command, at present each division only has three battalions under its jurisdiction: the mountain artillery battalion, the guard battalion, and the baggage battalion.

In the previous operation, the provisional Fifth Division was unfavorable and was directly withdrawn by Sun Weiguo to stand by, and Dai Jitao, the commander of the New Seventh Army, was a little worried.

He also handed over the special task force directly under the New Seventh Army to Chen Zhengwei to strengthen Chen Zhengwei's combat strength.

"Commander-in-chief, Chen Zhengwei's traffic trench won't dig directly under the nose of the little devil, right?"

Dai Jitao saw that Chen Zhengwei commanded the troops to dig a traffic trench, and he couldn't help but look at Sun Weiguo, and said with a puzzled expression on his face.

"No, it won't be long before Japanese bombers will appear, and as soon as the little devil bombers appear, the communication trenches will be destroyed." Sun Weiguo shook his head and said.

At this time, on the Japanese position, at this time, the wing headquarters of the 1st Guards Wing had begun to be established at the airport, the 1st Brigade of the 1st Guards Wing, the 2nd Brigade, the mountain artillery squadron directly under the wing headquarters, and the anti-tank artillery squadron had also come here, and the main force of the 1st Guards Wing was currently responsible for guarding the airport, and the 3rd anti-aircraft artillery team was also strengthening their operations.

THE 75MM ANTI-AIRCRAFT GUNS OF THE ANTI-AIRCRAFT ARTILLERY TEAM WERE FIRED FLAT, BUT THEY POSED A GREAT THREAT TO THE TROOPS OF THE PROVISIONAL FIFTH DIVISION WHO HAD ATTACKED BEFORE.

"Wing Commander, the Chinese troops are attacking again, but now the Chinese troops are not directly attacking our position, they are currently digging fortifications, and I don't know what they want to do."

In the rest area of the airport, the 1st Guards Wing set up a wing headquarters here, and at this time, the captain of the Dazuo Wing was looking at the map, and the chief of staff of the wing came to him to report.

"The Chinese troops are digging fortifications?" After hearing the report, the captain of the Great Zuo United asked with a puzzled expression on his face.

"Yes, the Chinese troops are digging fortifications, they are digging fortifications in the direction of our position." The chief of staff of the wing said again.

The captain of the Great Zuo Wing stood up, he walked directly upstairs, and when he came to the upstairs observation room, he directly raised the telescope to observe.

There was already a large area of dust flying around the airfield, and although he couldn't see it clearly, he could still see the traffic trenches on the periphery of the position, and these traffic trenches were approaching the position, and it might not be long before these traffic trenches would dig into his position.

After seeing this scene, Captain Dazuo showed a solemn expression on his face, and he realized that the Chinese troops intended to use the earthwork to advance.

"Contact the 15th Air Force immediately, and let them immediately dispatch bombers to support the operation, and it is absolutely impossible for the Chinese troops to dig the fortifications to the position."

With a serious expression on his face, the captain of the Great Zuo Wing quickly gave the order and said.

"Hey, Co-Captain." The chief of staff who followed immediately saluted and said.

Honorable to the troops of the 7th Division digging fortifications, they approached the Japanese positions little by little through communication trenches.

And the four battalions of the 1st Ranger Brigade, the 3rd Ranger Battalion, the 4th Ranger Battalion, the 5th Ranger Battalion, and the 6th Ranger Battalion are ready to attack.

The Zhao Lin antiaircraft artillery regiment also set up an antiaircraft position nearby, and dozens of antiaircraft guns, hundreds of machine guns, and antiaircraft machine guns began to be erected one after another.

The soldiers were digging a communication trench through which they would approach the little devil's position, but at this time, the mournful sirens began to sound from a distance.

Immediately afterward, bombers began to appear in the sky above, and twelve Japanese bombers appeared in the sky above the Honorable Seventh Division under the cover of fighters.

Without warning, aerial bombs began to fall, huge explosions rang out, and the surroundings began to be completely enveloped in gunsmoke.

The imp bombers dropped aerial bombs for half an hour, and after dropping aerial bombs, the bombers, together with the fighters, began to reduce altitude.
