When Chen Xin arrived at the repair point of Nanguan Dunbao, the sun was about to set.

In the Liaodong frontline area, there are no tall lighting equipment that has only appeared in China in the past two years.

Therefore, Chen Xin's inspection and condolence work in the Nanguanling area can only be left for tomorrow.

During the night, Chen Xin did not accept the suggestion of the commander of the guard flag team and the commander of the Nanguanling garrison to let him go to rest on the warship by the sea.

Instead, he chose to set up tents near Nanguan Dunbao, around the camp of those auxiliaries, and rested for the night.

Now, although spring has begun, and the plants and trees have re-sprouted.

However, the weather in Liaodong is still very cold and cold, at least, before the end of this Xiaoice period, don't expect the temperature to rise.

Especially at night, because there is no sunlight and the humidity brought by the coast not far away, it is simply crazy to be cold without heating.

In this night's time, with Chen Xin's physique that is almost to the limit of human beings, he actually woke up from the freeze twice.

"Well, there is still a lot of room for improvement in the logistics support of the Liaodong front! But should we add heating equipment, or should we improve the warm uniform? While muttering and thinking, Chen Xin wrapped himself in a blanket, put on a coat casually, and fell asleep again.

Early the next morning, the accompanying staff officers and interns consciously started their own work.

Divided into several groups, led by senior staff officers, they began to draw a map of the vicinity of Nanguan Dunbao.

The lecture hall has been open for more than 6 years, and the students who come out of it have long mastered various military skills, and this map drawing is one of the most important subjects.

Staff officers can not only use professional high-precision observation equipment to record the terrain and landform in detail, but also rely on the most rudimentary tools in their hands to roughly measure the height and length of the mountain peak.

In fact, the map of the vicinity of Nanguan has already been drawn up and distributed to the front-line combat units.

This surveying and mapping is mainly to exercise the field operation ability of the interns, and most importantly, to exercise the rapid surveying and mapping ability of the interns.

Therefore, they did not carry those professional high-precision measuring equipment, but only issued a few simple equipment such as rulers and artillery mirrors.

The staff officers only played the role of thinking and supervising, and were not directly involved in the surveying and mapping work.

Interns, all you need to do is map the height and length of the mountain with contour lines, and then indicate the nearby rivers and roads.

In fact, even this kind of rudimentary map is far more accurate than the maps of either the Ming army and the Later Jin army at this time.

In order to ensure that the map is not captured and used by the enemy, the Huaxia Army also has extremely strict map use specifications and burning measures.

Not long after the staff officers left, Zachdan came to Chen Xin's station.

Previously, when Chen Xin went to inspect Lushun and Jinzhou, Zakdan happened to go to the vicinity of Fuzhou to conduct close reconnaissance of the enemy's recent movements, so neither of them met.

Yesterday, when Zachdan returned to Golden State, he heard that Chen Xin had been there, so he chased after him early this morning.

Chen Xin led Zachdan to greet each other, and on the other hand, they went to the vicinity of the Nanguan River to have a look.

"Look at the amount of water in this little river."

Chen Xin took out the saber he was carrying, inserted it into the river, measured the depth in several places, and then roughly measured the width of the river, and continued.

Although the flow of water in this small river is not too much, it is absolutely no problem to supply at least one cavalry battalion.

Moreover, this Nanguan River flows into the ocean towards the east, so that the east of Nanguan naturally forms a barrier.

This kind of terrain, even if the cavalry troops can pass smoothly, but the logistics carriage that transports grain, grass and materials. The wheelbarrows, shield cars, and other standing vehicles of the Houjin Army cannot pass at all. ”

As he spoke, Chen Xin's finger pointed to the open terrain to the east and said, "Over there, our army can find a way to build three beacon towers in the area along the river."

No, the statement of the beacon tower may not be accurate, and it may be more appropriate to say that the outpost is called.

The large army can't go, and once there is a small group of Houjin cavalry who want to sneak in from here, the post can play a good warning role, once the signal is issued, the cavalry in the Nanguan Dunbao can attack from the flanks and teach them a lesson. ”

Zachdan nodded and replied, "This area of Nanguan is indeed a good place, the dungeon fort is built on the Nanguan Ridge, occupying the commanding heights of this place, and all the changes around it can be seen.

The subordinates have also been here many times during this time, and they have some plans, and the subordinates are going to build a simple small pier on the beach on the east side.

Before the newly occupied areas south of Jinzhou became self-sufficient, grain from southern Liaoning still had to be transported from the country.

Once the wharf is built, the grain can be transported directly to the local wharf from the country by sea.

Then, it is transferred here by small boat, and along the way, it is all water transportation, which is not only safe, but also extremely convenient, and saves a lot of transportation costs compared to land transportation.

Moreover, there are large fertile fields in the southern direction of Nanguanling.

As long as the expansion of our army is completed, a certain number is deployed in southern Liaoning, and a certain initiative is occupied, we can begin to expand the area between Jinzhou and Lushun.

The vast land here can also be used for large-scale tuntian to settle the refugees migrated from the Ming Kingdom, which can greatly alleviate the logistical supply problem of our army and make our army invincible. ”

Chen Xin nodded.

It has been three months since the Battle of Dalinghe ended, and the final result of the battle has already spread.

Although Zu Dashou still followed the trend of history, he surrendered in the early battle of Dalinghe (that is, the Dalinghe Battle of Daming against Houjin).

However, as in history, he took advantage of Huang Taiji's self-confidence after many victories, as well as the greed to take Jinzhou lightly, and offered Huang Taiji a strategy for him to pretend to break through and enter Jinzhou as the internal response of the Houjin army, and jointly seek to capture Jinzhou City.

Zu Dashou is indeed worthy of being a representative figure among the warlords in the late Ming Dynasty, he pondered Huang Taiji's thoughts very thoroughly, and he put forward this strategy according to Huang Taiji's thinking, which Huang Taiji could not refuse.

If you lose Zu Dashou, at most you will just lose a general.

However, if Zu Dashou is really willing to act as an internal response, then the Houjin army can easily take the strong city Jinzhou City, which has blocked his Laozi for decades.
