Hu Weidong also exhorted Yang Wenhan and others, who had stayed behind to establish the base areas, that before the Japanese army invaded China in an all-out way, the Jidong Independent Regiment should focus on developing, organizing, and mobilizing the masses, and the troops should temporarily adopt the strategy of "uniting the troops with the people," with the landlords' armed forces who had defected to the Japanese as the preferred combat targets, followed by the "regular" puppet army with an organization, and that they should not attack the Japanese army lightly without absolute certainty, and should try not to capture cities and towns, let alone touch the county seats, and that the base area regime will temporarily display itself as a two-faced regime with "white skin and red hearts." After the devils fully invaded China, the territory was occupied and the troops were scattered, and the anti-Japanese base areas in Pingxi and Hebei were also established, and then the eastern Hebei launched a large-scale launch, which was called a fatal sword, if the flag was erected too early, the Japanese army in North China was regarded as the target of the public before they dispersed their forces, not to mention Yang Wenhan's current more than 1,000 people, even if there were tens of thousands of troops, it would be in vain

After the capture of eastern Hebei, the Red Eighth Army naturally still had to confiscate Japanese pseudo assets as usual, needless to say, it was another ill-gotten gain. In addition, Hu Weidong attaches more importance to the fact that Tangshan Jiaotong University is famous for its civil engineering majors, and famous experts such as Mao Yisheng and Lin Tongyan are all from this school, and in order to protect important facilities such as arsenals in the western Henan Soviet District, a large number of fortifications must be built, and the construction of roads and bridges is also in urgent need of a large number of talents, and Hu Weidong will naturally not let it go.

However, although the harvest in eastern Hebei was not small, Hu Weidong left more than 10,000 Japanese troops in Tanggu to advance into eastern Hebei first, which was really a helpless move, after all, Tanggu was protected by Japanese naval guns, and it was by no means something that the Red Eighth Army could gnaw down. Although theoretically there are more army artillery can be bombarded with naval guns, but it also depends on what kind of warship, there are three battleships in the Japanese fleet outside Tanggu Port, and more than a dozen giant cannons with a caliber of more than 300mm are terrifying, not to mention, what is even worse is that the Red Eighth Army now has no artillery that can penetrate their thick armor (Note 1), and can only be beaten but cannot effectively return fire, which is absolutely devastating to morale. After all, no matter how bad it is, it can be regarded as an effective counterattack after defeating a few carrier-based aircraft, and it will not produce that kind of desperate mood, but fortunately, no matter how far the range of naval guns is, they are only naval guns, as long as they are not too close to Tanggu, the Japanese fleet wandering outside the harbor will also have no way to take the Red Eighth Army

Although the Japanese troops in Tanggu could not be helpless for a while, Hu Weidong still sent a reconnaissance unit of several dozen people to Tanggu to monitor the movements of the Japanese troops in accordance with the usual practice. But even Hu Weidong himself did not expect that soon after the advance division entered eastern Hebei, the reconnaissance team sent back an important piece of information that the Japanese fleet outside the harbor had actually left

It turned out that the Japanese army and navy were in trouble again; due to the intensification of the previous contradictions, and the fact that the original escort mission had been completed, and the bombing mission could not be continued, the Japanese Admiralty felt that leaving the huge fleet off the coast of Tianjin would not only waste fuel, but would also give people the illusion that "the navy was currying favor with the army," so it recalled the task force without aircraft carriers to the mainland, and the army, for the sake of face, also relied on the fact that there were more than 10,000 remnants of the Fifth Division. In addition, most of the heavy weapons belonging to the division and regiment are still there (priority is given to bombing troop carriers with more troops), so naturally they will not let go of their bodies and beg the navy to stay. As a result, the powerful task force of the Japanese army left the 5th Division of the Army, which was full of wounded soldiers, and returned to China with Shi Shiran

Hu Weidong was already very clear about the contradictions between the Japanese army and navy, and naturally thought of this possibility, and the idea of taking the opportunity to recover Tanggu and eliminate the remnants of the Japanese army suddenly germinated in his heart, but he was worried that the withdrawal of the Japanese fleet was just a trap. Although the longest range of the Japanese naval guns could reach 40 or 50 kilometers, after all, there was a Tanggu city in the middle when they carried out fire support, and the 8 Type 89 150mm field cannons and 24 Type 92 105mm field cannons captured by the Red Eighth Army in Fengtai had a range of more than 18 kilometers. It should have been too late to retreat to a safe distance, and if there is no trace of the Japanese fleet on the sea for a whole day of shelling Tanggu, then Hu Weidong's guess has been confirmed, and he will naturally not let go of this great opportunity to completely annihilate the Japanese army in Tanggu...,

In addition, Hu Weidong also had the idea of luring the devil out of the city to fight back, but unfortunately because there were too many wounded soldiers and low morale, the devil was bent on defending the city, which made Hu Weidong's intention to destroy the enemy in the field frustrated. But with the powerful artillery fire of the Red 15th Army now, even if the devil can't shrink, he is just waiting for death

Although the Japanese army knew about the indirect shelling of Jishu, they did not expect that the Red Army actually mastered it (although the Japanese spies obtained some information about the Red Eighth Army from the Nationalist Army, because the battle reports of the Nationalist Army have always been not detailed enough, the intelligence is far from detailed enough. It was used against them, and they actually smashed shells like garbage, and even the artillery of their Fifth Division, a permanent division, had never been so extravagant, and it was inevitably a little unprepared for a while. What is even worse is that a considerable number of the more than 10,000 Japanese soldiers were wounded and had difficulty moving, and as a result, more than 3,000 of them were directly buried alive by the collapsed houses because they did not have time to escape

The shelling continued until the next day, killing more than 5,000 enemy troops, and the blow to the morale of the Japanese was even more fatal. Although the artillery wing of the Fifth Division survived the air raid, the field artillery they were equipped with could hit as far as more than 10 kilometers, and they were simply unable to counterattack the Red Army's long-range cannons. In particular, the 5th Division lost their division commander and all its officers in the air raid on the sea, and the only two remaining commanders of the Dazuo Wing were also killed and wounded in this heavy artillery bombardment

Note 1: The one-ton bomb of the Type 93 heavy bomb also has to hit the vital parts, but as a horizontal bomber with poor bombing accuracy, this is simply an impossible task, unless hundreds of planes surround one like the old United States in the late stage of World War II. Before the breakthrough of the anti-armor jishu, only 305mm caliber guns or heavy torpedoes were more effective against battleships (especially new battleships built after World War I).
