The second update arrives, ask for collections, ask for recommendation votes! Thank you for the book friend Shatian Stone, the next stop ★, and the reward of Niu A Niu!

The M1904 light howitzer is an imitation of the German 1898 type 105 mm light field gun, with an increased barrel and increased firing range, a caliber of 105 mm, a barrel length of 25 times the caliber, a gun weighing 1.5 tons, a shell weighing 15 kg, a muzzle velocity of 400 meters per second, and a firing range of 8 kilometers to 10,000 meters. Thirty-six 105-mm light howitzers began shelling, as if they were going to destroy the world.

Fireballs rose in the queue of the Heilongjiang patrol battalion, and the shock wave generated by the explosion of the shells directly tore the fragile human body into pieces, and the stumps and broken arms flew everywhere. Shrapnel is everywhere, harvesting life to the fullest.

The M1904 light howitzer was followed by regimental artillery batteries of three infantry regiments deployed in the city, each armed with nine M1904 field guns. This is an imitation of the French M1897 field gun, with a caliber of 75 mm, a barrel length of 36 times the caliber, a gun weighing 1,000 kilograms, a shell weighing 5.5 kilograms, a muzzle velocity of 550 meters per second, and a firing range of more than 8,000 meters.

Although the number of 75-mm field guns was less than that of 105-mm light howitzers, the rate of fire was far superior to that of 105-mm light howitzers. So much so that after the start of the massive shelling, 27 75-mm field guns fired much more shells than 36 105-mm light howitzers. Of course, in terms of power, the 75-mm field gun is obviously not comparable with the 105-mm light howitzer.

At the same time, mortars erected on the walls of the city opened fire. All the mortars were firing at the maximum rate of fire, which directly led the officers and men of the Heilongjiang Patrol Battalion to encounter the most powerful artillery fire they had ever seen in their lives.

Dense shells, like a storm, struck. The thousands of officers and men of the Heilongjiang Patrol Battalion who participated in the attack were like fallen leaves in a storm, torn apart by light. Countless officers and soldiers were directly killed, and the rest of the people were also stupid.

Such a fierce artillery bombardment caused huge losses to the Heilongjiang patrol. Again, this is a demoralizing blow to their morale. Many officers and men of the patrol battalion turned around and ran away as soon as possible. By this time, they had stopped thinking about the promises of high bounties and promotions. Saving your own life, that's the most important thing!

Cheng Dequan and Hulan, who were watching the battle in the rear, were also dumbfounded, as if they couldn't believe what they saw in front of them. This time, Cheng Dequan put the main force of the Heilongjiang patrol battalion into it, but what they were waiting for was heavy losses.

"This, what's going on? How could the Ma family father and son have so many artillery? Cheng Dequan was so heartbroken that he almost fainted. The sudden outbreak of such a fierce shelling in Binjiang City was completely unexpected. There is no doubt that this attack by the Heilongjiang patrol battalion undoubtedly hit the iron plate.

"General, I don't know! It stands to reason that with the strength of the Ma family's father and son, if they had so many artillery, they would not have been defeated by us last time. Hulan also wanted to cry without tears.

"Damn, this is the army of other warlords, most likely the army of Jilin. They actually meddled in Heilongjiang's affairs, and I want to go to the court and severely punish these guys. Cheng Dequan was like thunder.

"General, let's withdraw the dragon general first and then think about it in the long run! Otherwise, I'm afraid I won't be able to leave. Hulan Jian said.

Cheng Dequan nodded, and he immediately ordered a retreat. However, as soon as his order was given, the 32nd Infantry Regiment and the 33rd Infantry Regiment of the 33rd Infantry Division of the Jilin Army launched an attack. Two infantry regiments, totaling more than 9,000 people, launched a siege for the Heilongjiang patrol battalion. And the 31st Infantry Regiment also rushed out of Binjiang City.

Under the artillery fire of the Jilin Army, the officers and men of the Heilongjiang Patrol Battalion, whose morale was gone, simply did not have the courage to resist the attack of the Jilin Army, and they either turned around and fled in all directions, or directly raised their hands and surrendered to the Jilin Army. Some of the officers and men of the patrol battalion who were blocked from retreating directly surrendered.

For the officers and men of these patrol battalions, they are only here for this salary. Since the battle was lost, between small lives and surrender, it is natural to choose to surrender. Anyway, they have no loyalty to Cheng Dequan at all. They were just doing it for money.

A large number of officers and men of the patrol battalion surrendered to the Jilin Army, even as a formation. It can be seen how weak their will to fight is.

In just over two hours, the battle was over. Of the more than 10,000 officers and men of the Heilongjiang patrol battalion who attacked Binjiang City, all but a very few escaped, and the rest stayed. Either they became cold dead bodies on the ground, or they became prisoners of the Jilin Army.

However, it is a pity that Cheng Dequan, Hulan and other senior Heilongjiang generals took advantage of the chaos to escape. If you can catch them, then the next battle will be much easier. However, even so, after the main force of the Heilongjiang patrol battalion was eliminated, the 3rd Infantry Division was able to capture the entire territory of Heilongjiang lightly, and Cheng Dequan no longer had the capital to block the Jilin Army. And the Jilin Army will obviously not give Cheng Dequan a chance to breathe anymore.

In the afternoon of the same day, Wu Haoxuan immediately ordered the 31st Infantry Regiment and the 32nd Infantry Regiment to march to Longjiang, while the 33rd Infantry Regiment and the troops directly under the division headquarters stayed behind to clean up the battlefield, and then marched to other areas of Heilongjiang.

Ma Tengxi's father and son also learned the news of the victory of the 3rd Infantry Division at this moment, and the father and son all rushed to say hello to Wu Haoxuan. It's just that the mood of their father and son is a little bitter. The 3rd Infantry Division was no longer their army. After defeating Cheng Dequan, Heilongjiang will also become the territory of the Wu family's father and son. And all their father and son can get is the government jurisdiction of Heilongjiang. Moreover, in terms of government affairs, Heilongjiang also has to obey the guidance of the Jilin Governor's Office. In other words, Ma Tengxi has become Wu Xingquan's subordinate.

"My father-in-law has won the award, and this is all the soldiers' lives. In addition, Cheng Dequan's troops were too ineffective, although there were more than 10,000 people, they were not vulnerable at all. Even if the 3rd Infantry Division sent only one infantry regiment, it would be able to defeat them lightly. Not to mention that the 3rd Infantry Division was originally superior in strength and weaponry. After winning the battle, Wu Haoxuan's mood was also very good.

It's just that hearing Wu Haoxuan say this, Ma Tengxi's father and son became even more depressed. If Cheng Dequan was really so easy to deal with, then their father and son would not have been defeated by Cheng Dequan last year. It's not that Cheng Dequan is too weak, but that the Jilin Army is too strong!

Under such circumstances, Ma Tengxi and his son may have no other choice than to honestly accept the leadership of the Jilin Overseer's Mansion. After all, there was no army in their hands, and even if they had other thoughts, they would not dare to express themselves. Otherwise, it's looking for death.

The next day, Wu Haoxuan personally led the troops directly under the 3rd Infantry Division and the main force of the 33rd Infantry Regiment to Longjiang, preparing to solve Cheng Dequan in one go. As for the riverfront, it was defended by a battalion of the 33rd Infantry Regiment. At the same time, more than 8,000 captives were also taken over to their care.

Cheng Dequan and Hulan, under the protection of their own soldiers, fled all the way west from Binjiang City, like lost dogs. This battle not only caused heavy losses to their troops, but also completely destroyed their confidence.

Cheng Dequan originally thought that he could occupy Heilongjiang and rely on Heilongjiang to fight against the Feng warlords. After defeating Ma Tengxi's father and son, he even thought that the Feng warlords were vulnerable, and they were just a group of upstarts who were lucky enough to hug Yuan Datou's thighs.

However, the battle of Binjiang City made him thoroughly aware of the gap between him and the Feng warlords. This is just Wu Xingquan's Jilin meddling, and he has no power to fight back. If the other two warlords of the Feng clan intervened, the consequences would be even more disastrous.

Cheng Dequan and Hulan fled all the way back to Longjiang, and when they set out on the expedition, there were more than 15,000 people, but now only more than 100 people have returned with them. Although, there are still 5,000 people defending Longjiang. However, almost all of these 5,000 people were just new recruits. Even the elite troops in his hands can't compete with the Jilin Army, let alone these recruits.

This put Cheng Dequan in a dilemma, should he fight or escape? If you stick to Longjiang and resist the Jilin Army to the end, the final result will probably be the destruction of the city. The Jilin Army had terrifying artillery fire, and the low walls of Longjiang City were obviously impossible to resist the attack of the Jilin Army.

But if he escapes, where can he flee? The only way to do this is probably to return to Kannai via Mongolia. But even if he returned to Yanjing City safely, what was waiting for him would definitely be sitting on a cold bench. If Yuan Datou was more ruthless, he would even be executed directly for disobedience and disrespect. After all, Yuan Datou ordered him to return to Yanjing City to report on his work, because he was unwilling to give up the power and territory in his hands and stay in Heilongjiang to resist.

On April 15, the reconnaissance company of the 31st Infantry Regiment of the 3rd Infantry Division of the Jilin Army arrived at the foot of Longjiang City. The emergence of the Jilin Army made Cheng Dequan make a choice. Before the main force of the Jilin Army arrived, he led a part of the troops loyal to him, fled the Longjiang River with his family, entered Mongolia from the Horqin steppe, and then returned to Guannai via Chahar. Except for Hulan and other generals, only a very small number of people fled with Cheng Dequan.

The day after Cheng Dequan fled, the defenders of Longjiang City surrendered to the Jilin Army. The 31st Infantry Regiment of the Jilin Army entered the city bloodlessly and took control of the provincial capital of Heilongjiang.

Subsequently, the other divisions of the 3rd Infantry Division began to march to other cities in Heilongjiang. Everywhere I went, I was looking at the wind. By the end of April, the whole of Heilongjiang had fallen under the control of the Jilin Army.
