"If we don't fight Chengde and retreat south, the devil's air force will always follow us to bomb indiscriminately, and the casualties will be much greater than now, and the number of planes dispatched alone will skyrocket to three times the current one, and without the shelter and protection of urban buildings, the efficiency of Japanese aircraft bombing will be ten times that of now, even if the impact of the decline in air defense capability is not considered, the casualties of our army can reach 30 times that of this period, that is, more than 30,000 casualties, and this is still the result of underestimating as much as possible. What's more, with the same casualty figures, air strikes are much more demoralizing than guns, and we have now suffered 20,000 casualties, can we afford to lose nearly half of the casualties? In comparison, although there will be a lot of losses in attacking Chengde, it will be much smaller in the end, and it is better to die on the way to charge than to be chased and blown up by the devil's plane."

"Then can't you stay in Tianjin for the time being and not go back?" As soon as Zhang Hao said this, he realized the problem, if he stayed in Tianjin all the time, the danger would only get bigger and bigger, and because of the occupation of the Red Army, most of the daily necessities needed by the citizens of Tianjin were cut off, and now there were already some complaints in the city, if it took a long time, it would be inevitable that some discordant incidents would not occur, and the Red Party would have to lose a lot of points politically. Zhang Hao was not an ordinary person, and soon turned a corner and agreed to Hu Weidong's battle.

As Hu Weidong expected, because the Japanese army was defenseless, the Red Army attacking troops resolutely carried out the order to march day and night, and it was not until they were less than 20 miles away from Chengde that the Japanese finally discovered it, but it was too late at this time. Even if they did not bring heavy artillery, they were not able to withstand a devil infantry brigade and a unit directly under the wing of several hundred people in Chengde City, especially the Type 90 75mm field artillery with a range of nearly 14 kilometers was a great achievement. With the observation data sent back by the scouts in the city, more than 10 Type 90 field guns did not have to enter the city to directly rain shells into the Chengde airport, dozens of Japanese planes that had just been stationed not long after they had time to take off were blown up or burned, only two flight squadrons escaped because they had already taken off, but also because they lost their foothold and had no time to bomb the siege Red Army, all of them hurriedly flew to the nearest Jinzhou airport from Chengde, because it was an emergency lift-off, most of the fuel did not have time to fill up, if there was a delay in time, I'm afraid that the crash will be inevitable

Coupled with the previous achievements, the Red Eighth Army has successively destroyed more than 100 devil planes (including two aircraft carriers), although there is a great element of luck in it, but Hu Weidong and the Red Eighth Army are still the number one sufferers of the Japanese air force. However, although this made Hu Weidong and the Red Eighth Army more and more famous, it also caused a series of butterfly effects that Hu Weidong did not expect now

After receiving a distress signal from Chengde, another devil brigade stationed in Chifeng hurried to the rescue, but they quickly collapsed under the blows of the Red Army's artillery fire, which had no city defense to defend. Although none of the cannons above the caliber of 105mm were brought this time, in the field battle, hundreds of mountain artillery field guns and a larger number of mortars were enough to rely on numbers to make up for the lack of power of individual guns. What's more, a devil infantry brigade is only equipped with only 6 infantry guns, and in the face of the Red Army's 20 times the strength and 50 times the heavy firepower, no matter how brave the devil is, it will still be quickly wiped out. Especially at this time, because most of the original aviation units in Jinzhou have been transferred here, and the new planes have not been replenished, the air support that the devils have always regarded as the hole card cannot be counted on for a while, which makes the Japanese troops inside and outside the city more and more discouraged, even if the officers try their best to restrain them, there are also desperate devil soldiers who abandon their weapons and surrender, but Hu Weidong believes that this battle must be quickly resolved, and the goal of the battle is only to completely destroy the Chengde airport, so that it cannot be repaired in a short time, where is the time to surrender? So whether it was the devils who resisted or those who did not resist, they were all swept directly by the unmerciful artillery fire and machine guns...,

Since the main force of the Japanese army in Chifeng had been wiped out, some brigade-level cadres who felt that it was not enjoyable enough once suggested to Hu Weidong that they attack Chifeng and completely recover Rehe. However, Hu Weidong believed that Chifeng was close to the three eastern provinces and had direct railway connections, and that the Japanese army could transfer the main force of the Kwantung Army stationed in the eastern part of the puppet Manchurian army to guard against the Soviet Union in a short period of time, and there was more than one Japanese airfield in Jinzhou that could reach Chifeng. The strategic significance of this base area theory is far from being comparable with that of the eastern Hebei base area, but no matter how small the mosquito is, it is still meat!

After detonating a total of dozens of tons of explosives to effectively blast all important facilities at Chengde Airport and ensure that the airport could not be repaired and used for at least a month, Hu Weidong, who was finally relieved, led his troops south to join up with the military commanders who had already left Tianjin. In the meantime, although the Red Army was still in ambush and nocturnal, the reconnaissance efficiency of the Japanese planes was greatly improved after locking on the general range, and once the devil's reconnaissance planes found them, the Japanese planes would soon hear the wind and chase the Red Army as if they were crazy and bombed indiscriminately, and the air defense forces were naturally still the focus of the attack, even though the camouflage troops that had just been built played a great role, but the losses were still increasing rapidly, and by the time the two armies met, the Red Army's anti-aircraft guns had almost all been destroyed, and only one anti-aircraft machine gun remained. More than 200 light and heavy machine guns were destroyed and the air defense capability plummeted, and the devil's planes became more and more unscrupulous, and the casualties of the Red Army skyrocketed. When the large units of the Red 15 th Army finally left the combat radius of the devil plane, because the casualties caused by the air raid had exceeded 5,000, Hu Weidong couldn't help but rejoice in his original insistence, if the Chengde Airport was still there, then the intensity and efficiency of the devil's air attack (the difference between the mountains and the plains) were several times higher than now, and the duration was longer, and the current Red 15 th Army may have been disabled

However, the Japanese planes were only available at one airfield in Jinzhou, and the number was limited after all, and they concentrated on chasing and killing the Rehe detachment led by Hu Weidong, so naturally they could not take care of other directions, and as a result, the heavy artillery and tanks at the headquarters of the Eighth Army Corps in Tianjin left the combat radius of the Japanese planes in Jinzhou without any losses. However, this is also because Hu Weidong boldly ordered the mechanized troops of the headquarters to leave Tianjin before the infantry and rush out of the dangerous area overnight, even the slowest 240mm heavy artillery, under the tow of a special tractor, is enough to drive more than 100 kilometers along the road in one night, and this has already gotten rid of the threat of Japanese aircraft
