Nanguan is actually not a checkpoint, but a mountain.

In the first year of the Apocalypse, Mao Wenlong sailed to Liao with 197 soldiers, conquered Houjin in Zhenjiang Fort, a fortress in the southern Liaohai region, and built Dongjiang Town, and absorbed a large number of refugees from Liaodong, and in just five months, tens of thousands of Liao people were collected.

After capturing the islands off the coast of Liaodong, Mao Wenlong was not satisfied, but sent Chen Jisheng, the deputy general of Dongjiang Town, to divide Kuandian, and the general Zhang Pan to advance into Lushun and other places, thinking that it was a forward base for attacking the hinterland of Liaodong.

After Zhang Pan captured Lushun, he was impressed by the topography of the Liaodong Peninsula, so he decided to build forts in Jinzhou and Nanguanling in Lushun to stabilize the frontier fortress of Lushun.

In the fifth year of the Apocalypse, after the Dongjiang Army achieved a great victory in the Great Black Mountain, the Apocalypse issued a holy decree to add Zhang Pan as the deputy chief soldier of Dongjiang Town, and to dig a canal in Nanguan to communicate with the Liaodong Peninsula, so that the Ming army and naval divisions could come to the aid at any time, and the battle line of the Ming army in Lushun could also move forward.

It's just that due to the betrayal of the traitor, Zhang Pan was killed, and Lushun fell again.

After the Dongyu regained control of Lushun, in order to prevent the Ming Navy from attacking Jinzhou along the coastal road, Huang Taiji ordered to hollow out the walls of Jinzhou and Nanguan, and after more than ten years, the once impregnable Nanguan Fort has become a ruined wall.

Dai Shan, the prince of the Qing Dynasty, and Dorobele Karchu, the owner of the Red Banner with Red Flag, never thought that he would flee to Nanguan Fort in desperation, which was picked up by the Manchurians himself, and was firmly trapped by the Ming army in the square inch of dozens of miles south of Liaoning.

The reaction of the Qing army was not unpleasant, and after the defeat in the field battle of Lushun, Dai Shan issued a military order to retreat on the same day.

But he never imagined that the flat and wide official road when he went to Lushun had been dug with potholes, and the Jinzhou side was dug by the Ming army with a trench one and a half zhang wide, and the water of the Dengsha River was introduced.

Of course, Dai Shan did not think of breaking through the Ming army's defense line that blocked the only retreat of the Manchurian soldiers of the two red banners.

On the contrary, after arriving in Jinzhou, the Manchurian soldiers of the two red flags launched round after round of attacks on the Ming defense line in front of them for the sake of life and death.

The remnants of the two red flags of more than 10,000 soldiers of the Eight Banners also knew the consequences of the back road being cut off by the Ming army, and summoned Yu Yong to cut down a large amount of timber at the southern end of Jinzhou under the command of their respective Niulu, Dutong, and staff leaders, and then bundled them together as a wooden bridge for crossing the trenches of the Ming army.

It's just that after the Manchurian soldiers launched an offensive, the artillery of the Ming army began to roar in front of them.

Dai Shan really couldn't figure it out, where did the little Li thief get so many artillery, when Lushun and the Ming army fought, the little Li thief put out more than 100 Hongyi cannons, and now in Jinzhou, those Ming thieves with the Li character general banner put out hundreds of artillery.

The dense scattered bullets and the guns fired by the Ming army on the opposite side formed a barrage in front of the trench, and the big poles carried by the two people were not far behind those small cannons in terms of firepower, and the simple shields of the Eight Banners could not stop the Ming soldiers who were waiting for work.

Of course, to the despair of the Eight Banners Army, their Red Banner Gushan Ezhen Tezu actually took refuge in those lowly Southern Barbarians, which made the morale of the Eight Banners who had already suffered defeat in Lushun extremely low.

When the Manchurian soldiers to whom the red flag belonged saw their former master following the Ming generals like a pug, they no longer had the courage to fight to the death with the Ming army, and they even knelt down in front of the Ming army's trench and begged to surrender to the Ming thieves in front of them.

"The Mongols are unreliable, and the Haixi Jurchen people are also unreliable, what should we do now, father?"

After Jinzhou was repulsed by the Ming army, Dorobel Karchu, who fled to Nanguan, no longer had the vigor he had when he became the lord of the red flag, and stared at Prince Daishan who was sitting on a stone like a pitiful worm.

"We have just been defeated in Lushun, and we have trekked dozens of miles overnight to Jinzhou, the soldiers are already tired, and the surrender of Tezu has reduced the morale of our Manchurian soldiers to the extreme, you send someone to inform Namutu who hid on the Nanguan Ridge, let him go down the mountain and join us, one is prosperous, one is lost, we and the Mongols are grasshoppers on a rope, once the food is cut off, everyone will starve to death."

Dai Shan is also helpless, from Shenyang to Lushun, he only brought a month's rations, these 20 days, the army's rations have been less than 10 days, the Ming army's defense line is quite tight, now only put aside prejudices, concentrate forces, raise the morale of the soldiers, and then storm Jinzhou, see if you can break out of the Ming army's defense line.

"Alas!"

Karchu sighed heavily, he also knew that what Dai Shan said was the truth, now there are two red flags and one army and horse in southern Liaoning, and if you want to break through the defense line of the Ming army, you can only concentrate on fighting to the death.

Going to catasish the Mongols with Khalchu, Dai Shan also had a good intention, Khalchu was a Manchurian clan and his own son, and under the cold lips and teeth, Namutu would inevitably lead the army down the mountain.

After arranging Khalchu, Dai Shan turned his head to look at the two red flag generals such as Balanqi and He Shuotu.

"Baranqi, you are an old man with a red flag, Tezu surrendered to the Ming Kingdom, and now the morale in the flag is extremely low, these days, your task is to try your best to appease the morale of the army and improve the morale of the army."

"Heshuotu, you selected five Niu Lu in the Zhenghong Banner to arrange a defensive line in Nanguanling to prevent Xiao Li Thief from leading the army to pursue, remember not to fight, just spread rolling logs and stones."

In a desperate situation, Dai Shan did not despair, he knew that if he fell at this time, then these more than 10,000 Manchurian sons would really be over.

"Wow!"

He Shuotu and Ba Lanqi responded to the order, both of them are authentic Jianzhou Jurchens, naturally it is impossible to casually vote for the thief who has always been regarded as a pig and a dog like Tezu.

Faced with the defense line of the Jingbei Army and the already low morale, Dai Shan had to stop retreating, pack up his men and horses, store his strength and morale, and prepare for the final death struggle.

However, Li Dingguo, who was guarding Jinzhou, did not stand still as Dai Shan thought, and after forcing back the two Red Banner Manchurian soldiers, he restarted the construction of the fortress on the basis of the original Jinzhou Guard.

The Jingbei Army carried 300,000 catties of cement on the Northern Expedition, which became the main material for the construction of the fortress.

Countless soldiers accompanying the army began to dig the foundation along the original site of the Jinzhou Weibao in front of the Qing army sentry on the opposite side of the trench.

Timber and mangosteen from nearby mountains were also transported in bundles to the fort site where the fort was under construction, and skilled carpenters and masons tied the timber and mangosteen with twine-soaked twine rope to build the framework of the fort.

Li Dingguo is fighting a righteous and bright Yangmou, either you come to break through now, or you sit and watch the general's fortress be built, and then wait for death in southern Liaoning.
