When the vanguard of Chen Jie's Second Division was smooth sailing, Wei Chong's Fourth Division was also bloodless, and successively occupied the first line of Xingnangang, Xianxing, Xinshangli, and Huangcaoling.

Wei Chong was different from Chen Jie, he directly drove an armored car and personally commanded the first assault group. The follow-up second wave of assault troops was handed over to Zhao Sanbao, deputy division commander, and the follow-up and deployment of the third wave of large troops were all handed over to Wang Sanju, chief of staff.

Wei Chong rushed to Xingnan Port first, and found that all the things that could be used had turned into scrap metal, and he was suddenly shocked in his heart: "How the hell can this work!" It's all in ruins, and it must all be rebuilt, what will the boss do in the future to support the big army? ”

"Operator, send a telegram to the headquarters immediately." Wei Chong saw that this battle could not be fought indiscriminately: "Report to the commander-in-chief: The destructive power of the cloud burst bomb is too strong, and there is not an inch left in the place where it passes, but all the industrial and civilian facilities have been destroyed, and it will be too difficult to rebuild in the future." ”

"In the future bombing of the Air Force, we must specifically select military targets, and we must not bomb them indiscriminately. In particular, the bombing of towns must be limited to certain areas. After all, this is our own territory, and what is destroyed is our own. ”

As soon as Bai Shujie received the telegram, he immediately applauded: "Okay, the little junior brother in the ancient tomb camp has finally grown up, and he already has a relatively long-term strategic vision, and he is no longer stunned, this construction is very timely!" ”

"This guy is extremely smart, he just likes to brag about himself, and his nostrils are pointing to the sky!" Zhao Jinxi smiled and said, "But his construction is indeed very timely. If it continues to be bombed like this, the industrial zone in Chengjin will be completely scrapped, and it will be useless for us to take it. On the contrary, it will take a lot of effort to rebuild, and the gains outweigh the losses. ”

Wei Chong's telegram touched a string in Bai Shujie's heart, and a very urgent research and development plan was introduced, and a flying group was about to be added to the air force: a strategic reconnaissance flight group.

To form such a brigade, it is necessary to have a high-altitude, high-speed, high-range, and photograph-capable reconnaissance plane. Bai Shujie made a phone call to the Institute of Physics of the Comprehensive Research Institute and issued an "Order on the Urgent Development of Electronically Controlled Aerial Cameras."

Soon after, Bai Shujie made another phone call to Munn of the Engine Research Institute, and at the same time issued an "Order on Using the DC-3 Medium-Range Transport Aircraft to Modify a Long-Range Reconnaissance Aircraft."

The command demanded: remove unnecessary auxiliary facilities and add two built-in fuel tanks in the wings. Replace the existing engine, the maximum level flight speed is 720 km / h, the cruising speed is 480 km / h, the range is 6,600 km, and the practical ceiling is 10,000 meters.

Equipped with 2 30mm nose guns and 2 12.7mm tail machine guns. Install a radar early warning system and a friend or foe identification system, install 4 electronically controlled telephoto wide-angle cameras, and set up a crew of 4 people.

"The DC-3 is still not good." After sending out the order, Bai Shujie felt a little regretful in his heart: "The speed is not enough, the height is not enough." The range is not enough, which means that the time in the air is not enough, and the scope of reconnaissance is too small. It seems that the development of a large high-speed long-range bomber has become imperative. ”

Press Bai Shujie to plan the strategic issue at the headquarters and leave it aside for the time being.

It is said that after the two formations of the air force completed the first round of bombing, Chen Jie's second division, Wei Chong's fourth division, and armored regiment had already rushed to the west bank of the Yangtze River.

That is, after a surprise attack of the time of a surprise attack, the front line of the troops advanced on average 170 km to the east. It controlled the Hongyuan in the south and the Linjiang line in the north, cutting off the connection between the 19th Division of the Little Devil and the direction of Wonsan.

At this point, the headquarters of the two infantry divisions and regiments and the two fortress headquarters of the little devils on the Korean Peninsula were divided into two isolated parts in the north and south. The coastline on the east and west sides of Pyongyang is temporarily free of enemies.

After Bai Shujie received the first battle report from the front, he immediately ordered the armored division directly under the headquarters to push the eastern defense line directly to the sea edge of Wonsan Port.

To say that this air defense division is actually a hodgepodge. Division Commander Gan Tong (concurrently), Deputy Division Commander Zhang Er, and Chief of Staff Ling Kaishan. Subordinate:

40mm anti-aircraft artillery regiment (2452 people): regiment commander Tan Mingliang, 96 half-track quadruple 40mm anti-aircraft guns;

88mm anti-aircraft artillery regiment (2452 people): regiment commander Luo Qingsong, 72 half-track double-linked 88mm high-level dual-purpose guns;

Armored train regiment (2452 people): 12 armored trains (one twin 203mm and 88mm anti-aircraft guns);

Dual-purpose armored regiment (2,452 people): 96 orbital land armored vehicles (each equipped with a 20mm six-tube phalanx);

Armored transport regiment (2,452 men): 4 armed freight trains, 72 trucks, 24 escort armored vehicles.

In addition, there is a guard battalion, a baggage battalion, and the entire armored division has 14,522 people.

To participate in front-line battles, it naturally makes no sense for rail armored vehicles to have railways, armored transport regiments; Tan Mingliang's 40mm anti-aircraft artillery regiment could not be moved, because it had to defend the key parts of Heiling and Dacheng Mountain. So what can move is Luo Qingsong's 88mm anti-aircraft artillery regiment.

From the top of the mountain to the eastern foot of the mountain, four battalions spread out in one line, and built their own air defense positions at Maoshan Port, Yuanshan Port, Wenchuan, and Plateau.

It was also this order of Bai Shujie that provided strong fire support for the 1st Division of the DPRK People's Liberation Army Xu Sanjiang to clear the remnants of the Yongxing Bay Fortress.

Wonsan Port, called Woody Bay, is a huge backwater bay and a natural deep-water wharf area. It is one of the four major ports in North Korea that the little devils care about the most.

The 15th Heavy Artillery Wing has more than 2,700 people, defending the 1st Battery, the 2nd Battery, the 1st Battery, the 2nd Battery, the 1st Battery, the 2nd Battery, the 1st Battery, the 2nd Battery, the 3rd Battery, the 4th Battery, the Xinzhangli Battery, the Yuanpingli Battery, the Yingcheng Battery, and the South End Battery.

Although all the forts were to defend the sea, it was not easy to rush into the fortress and slaughter more than 2,700 little devils.

The DW88mm high-level dual-purpose gun, in addition to fighting planes, is a good hand against tanks, armored vehicles, and pillboxes. After more than four hours of continuous bombardment by 72 twin-mounted anti-aircraft guns, all the fortified batteries were turned into slaughterhouses.

The commander of Yongxing Fortress, Tanaka Kudasa, finally carried forward the spirit of bushido, led the remaining more than 300 people, faced more than 100 cannons, and launched a decisive charge! In the end, all of them were killed by assault rifles more than two hundred meters in front of the position!

The biggest gain of this battle was the complete capture of 36 460mm fortress guns and a reserve of 55,200 shells.

Not only that, the regiment commander Luo Qingsong played at a super level, and even used the DW88mm Gaoping dual-purpose gun as a shore gun, using the high rate of fire to form a dense fire network, sinking the remaining 9 offshore gunboats of the little devil, and forcing dozens of cargo ships that were about to escape from Yuanshan Port, Maoshan Port, and Xingnan Port to the shore, and then captured the prisoners.

After receiving the report, Bai Shujie immediately ordered the Pyongyang City Government to urgently transfer 2,500 tons of cement and 750 tons of steel, and organize 2,000 workers to quickly repair all the forts. The artillery regiment of the 1st Division of the Korean People's Liberation Army sent a battalion to take over all the fortified batteries here.

At the same time, the ground forces seized the time to consolidate their front, but the Air Force did not have such concerns. Before the enemy has fully reacted, it is necessary to strike while the iron is hot.

Therefore, the commander of the Air Force, Zhang Nianzu, ordered two formations of heavy bombers to fight one more round, this time directly hitting the port of Chengjin, blowing up all the docks, and cutting off the enemy's escape channel from the sea. Then continue to raid in depth, directly bombing Ronan and Hoeryong.

The targets of this bombardment were Ronan's 19th Division Headquarters, the 75th and 76th Infantry Wings, the 25th Mountain Artillery Wing, and the Tank Squadron; This was followed by the 73rd Infantry Wing and the 14th Heavy Artillery Wing in Hoi Ninh.

Zhang Nianzu's guiding ideology is very clear: I think that the Northeast Army was unable to stop its strong defense line back then, and was forced to retreat again and again, the key is that the planes of the little devils always keep bombing in front.

Now I have an airplane, and the quality is better, and the bomb is more powerful, if you don't give the little devil a blow, it's too much to say.

The Korean Peninsula is a long and narrow region, with a width of only a few hundred kilometers from east to west. The B-17 bomber has a combat radius of more than 1200 km, which has enough time to pour all the ammunition down.

Because of this, after the four bombs they were carrying were dropped, the bombers circled around and began to use their aerial guns to strafe back and forth. So that the little devil has no idea what is going on, and he doesn't know who the enemy is.

The blitzkrieg designed by Bai Shujie finally saw the effect.

Throughout the day of July 28, 1939, the little devils on the Korean Peninsula spent time in the roar of airplanes, the bombing of aerial bombs, and the strafing of aerial artillery. Communications were interrupted between the command at all levels, and there was a complete disconnect between all the troops.

At around 3 p.m. on July 28, Chen Jie and Wei Chong had just picked up on the radio when they heard that the Air Force was not resting at all, but was preparing to raid overnight, which was a good opportunity. Therefore, after consulting again, the two men decided to attack the two armored regiments overnight.

Wei Chong's 4th Panzer Regiment advanced along the coastline, and Chen Jie's 2nd Panzer Regiment continued eastward along the Yalu River, and then flanked Chengjin to seize this important industrial site in one fell swoop. The 2nd and 4th Machine Gun Regiments then quickly followed up and further expanded their gains.

As of about 10 o'clock in the evening of July 28, more than 600 people from a coastal garrison of the little devils on the front line of Chengjin Port were all compressed into an abandoned long pit in the Yiyedong Iron Mine.

It's not that these little devils have a long life, but the bomber formation received an urgent order from Bai Shujie that they must obey the command of the ground forces for the bombing of the front line of Chengjin Port. This will be its own industrial base in the future, and you must not smash all the altars and jars.

Even so, in the face of the siege of two armored regiments, nearly two hundred armored vehicles, and a garrison of more than 900 people, it was simply impossible to gain a foothold. Finally, like ducks, they were driven out of the city, and their end has come!

This time it was not the Flying Fortress B-17 that came, but the Type 96 light bomber produced by the little devil himself. More than 600 little devils watched the fighter plane they were most familiar with roar down, and then the bomb fell overhead, and then, there was no more.

Chengjin District is liberated!

After telegraph communication, Chen Jie and Wei Chong were finally able to reluctantly determine: more than 33,000 people from the two field divisions ran 200 kilometers long distance, and finally annihilated less than 2,000 enemies, that is, two garrison brigades. And the vast majority of these people were wiped out by the Air Force, and the field division was left to run away.

The biggest gain is to liberate 9 county towns and recapture 4 ports.

At about three o'clock in the morning on July 29, 1939, Wei Chong's Fourth Machine Gun Regiment finally arrived at Chengjin Port, and Chen Jie's Second Machine Gun Regiment also rushed to the Huishan line by the Yalu River in the north.

Because the next thing is to really enter the combat state, because in front is the 19th Division and the Ronan Fortress Headquarters, below which there are three infantry wings, a mountain artillery wing, a 14th heavy artillery wing, and a tank brigade, with a total strength of more than 15,000 people.

After all, what happens next, let's see how it will be broken down next time.
