Qiao Youhua's order was quickly implemented, and tens of thousands of officers and soldiers of the heavy artillery brigade and the air defense brigade, as well as hundreds of armored vehicles, began to assemble one after another, advancing rapidly in the direction of Shanhaiguan.

The logistics department also went all out for them, preparing fuel and ammunition to supply the front line.

At the same time, the post-war reconstruction of Tianjin had also begun rapidly, and the chief of staff, Zuo Quan, thought of a good way, that is, to use the tens of thousands of puppet soldiers captured in the Tianjin Battle as free laborers and devote themselves to the reconstruction of Tianjin.

Rebuilding the homes of the people, in this way, not only speeds up the speed of reconstruction, but also saves the precious troops of the Dragon's Tooth Column and the Eighth Route Army, and only needs to send a small number of troops to maintain order and take care of it.

Qiao Youhua and Zuo Quan also transferred more than 20,000 reinforcements from the Eighth Route Army to Jixian, Tongzhou, Tangshan, and Qinhuangdao, and put them in charge of the defense of the large area from Tianjin to Shanhaiguan, which is a large area of northeastern Hebei, while taking into account local stability and law and order.

In order to prevent some young people from taking advantage of the vacuum of defensive forces in the above-mentioned areas, they oppress the people, steal and rob and kill, and disrupt local order.

In the command headquarters, Qiao Youhua had already summoned Ma Biao and Jiang Haidong, and the three of them changed into flight suits, and because Wu Ming had already left one step earlier, he went south to return to the main force of the 3rd Division in Texas.

Therefore, there were only three of them in the air support for the advance corps to capture Shanhaiguan, but fortunately, Shanhaiguan was much smaller than Tianjin, and the three fighters were enough to pose a great threat to the Japanese army, and the most important thing was to hit and boost the morale of both sides.

After everything was ready, Qiao Youhua said to Zuo Quan: "Chief of Staff, the command will be handed over to you, and we will go." ”

"Well, everything has me, don't worry, but you have to pay attention to safety, since the Kwantung Army may have intervened in the Shanhaiguan battle, then it is not ruled out that they may send land-based aviation to participate in the war." Zuo Quan nodded and reminded Qiao Youhua and the others to be careful.

"I have also taken this into account, so this time, I am the only one to fly the bomber, and Haidong and Ma Biao will fly the fighter jet to escort me!" Qiao Youhua sorted out the flight suit on his body and saluted Zuo Quan goodbye.

Ma Biao and Jiang Haidong also hurriedly stepped forward to salute.

Zuo Quan hurriedly stepped forward and saluted back, and said, "Treasure!" ”

The three of them walked out of the headquarters together, and Zhao Tiezhu, the deputy head of the guard regiment, had already been ordered to prepare the vehicles, and when he saw them coming out, he hurriedly stood up and saluted.

Qiao Youhua stepped into the jeep first, and after a while, the jeep quickly drove away from the Wanguo Commercial Building under the escort of a team of loaded guns and live ammunition dragon tooth guards, and galloped away towards the Wanjiazhuang Military Airport in the northwest of the city.

About half an hour later, one bomber and two fighters successfully lifted off from the runway of Wanjiazhuang Airport one after another, and the two fighters protected the bomber in the middle, one on the left and one on the right, and the three planes flew through the clouds and the sun at the fastest speed in the direction of Shanhaiguan.

At the same time, the first battle under the Shanhai Pass had come to an end, due to the Kwantung Army's strong resistance, the offensive of the advance corps was frustrated, and the casualties surged.

Because at this time, they had already received Qiao Youhua's reply, and Liu Jianhua learned that the heavy artillery brigade and the air defense brigade were coming, and Qiao Youhua and others would fly fighters to provide air support for them, and understood that this would be a valuable fighter.

Therefore, he hurriedly stopped the tentative attack and began to quietly deploy, transferring the two tank regiments and one air defense regiment of the advance corps to the foot of Shanhaiguan, so that the wall was within the absolute coverage range of his own artillery fire.

At the same time, the elite infantry of the two infantry regiments has also been divided into four echelons, and after their own air support and ground tank artillery fire have launched a fierce attack on the wall, they will launch a continuous charge, striving to take Shanhaiguan in one go and drive the Kwantung Army's sphere of influence out of the pass.

If this attack fails, then we can only wait for our own heavy artillery troops and other follow-up reinforcements to arrive, and then launch an attack on Shanhaiguan step by step, and fight a war of attrition with the devils.

Therefore, in order to boost the morale of the officers and men of the whole army, Liu Jianhua resolutely decided to personally lead the assault team to participate in the charge to show that he attached importance to this battle.

The contact with Qiao Youhua is maintained by radio at all times, so both sides know each other's location and movements.

The advance corps did not act rashly before Qiao Youhua and his three fighters arrived, and this process also gave the Japanese troops in Shanhaiguan a rare respite, but when they saw hundreds of tanks and combat vehicles and anti-aircraft air defense units waiting in formation outside the pass, the devils still couldn't help but feel timid.

The Dragon's Tooth Column set up such a big battle, and the fools knew what kind of fierce attack they would endure next, so the commander of the devil in the pass was so frightened that he sent several telegrams asking for help to the division headquarters of the 12th Division of the follow-up reinforcements.

Ask the 12th Division to speed up and come as soon as possible.

However, since Jinzhou is three or four hundred miles away from Shanhaiguan, since it received the mobilization order three days ago, the 12th Division sent an vanguard unit to Shanhaiguan first, and at the same time urgently summoned the main forces of its various units deployed in Jinzhou and its surrounding areas.

It has been a day or two since the assembly was completed and the materials were deployed, and within a day, the main force of the devils could not reach Shanhaiguan after walking the hundreds of miles of the Liaoxi Corridor anyway.

Therefore, no matter how the 12th Division accelerated, it was impossible to reach Shanhaiguan before the three fighters piloted by Qiao Youhua.

At about 11 o'clock in the morning, Qiao Youhua, Ma Biao, and Jiang Haidong drove bombers and fighters respectively to the sky over Shanhaiguan.

Without the slightest hesitation, the three of them drove the fighter plane towards Shanhaiguan and pounced.

Looking at the three fighters that suddenly appeared from a high altitude and quickly dived over, the Japanese troops at the head of Nanguan were very surprised, and like the Japanese troops in Tianjin, they did not expect that the air force of the Chinese army would appear here.

I thought it was my own fighters who came to reinforce the armored troops of the Chinese Army who were waiting outside the pass.

If that's the case, that's great, just when the devil soldiers were about to cheer, they found that one of the three fighters actually began to open the magazine in the air and drop heavy bombs one after another.

Moreover, soon, the fighter plane that was escorting it also rushed in the direction of the city, and suddenly tongues of fire erupted from under the wings and belly, and a large number of scorching course machine gun bullets pierced the void and shot quickly.

"Ah......hh Damn it! What's going on? Isn't this our fighter? The devils in the crowd suddenly screamed and fell down one after another.
