The idea of using the Nakdong River to build the Busan defense line was finalized after Ryu Il-won's on-site inspection.
Although Busan is a city on land, its geographical location is truly unique.
Behind this city is the sea.
Although Hou Jin was brave and good at fighting on land, he was completely worthless at sea.
In this way, there is no need to consider the rear in defensive operations.
The wide Nakdong River in the west of Busan flows straight to the sea, and there are a series of highlands on the east coast. This is definitely a terrain that is easy to defend but difficult to attack.
In particular, there is a mountain fortress inherited from the Silla era on Mount Geumjeong.
"All the materials transported will be sent here, and we will send people to guard this place ourselves."
Liu Yiyuan attached great importance to Jinjing Mountain City and planned to use it to build a frontline base.
The combat staff has recorded it and can execute it after returning home.
The land access to Busan is in the north.
There are two ways to come from Ulsan.
The road is between high mountains and ridges, and the terrain is narrow. Only one regiment of troops is needed to make it impregnable.
The other road is close to the sea and is also narrow, making it easy to be hit by sea fire.
Such terrain conditions make Busan absolutely easy to defend and difficult to attack.
"The commander-in-chief plans to use one division of troops to consolidate Busan's defense. It is absolutely sufficient. But the supplies needed here have to be transported by sea. I don't know if the Houjin side is determined to keep spending with us for many years?"
As long as the logistics supplies are sufficient, Liu Yiyuan is confident that he can hold on for a hundred years.
Can Houjin spend so long with Shandong?
Obviously not.
After the on-the-spot investigation, Liu Yiyuan was full of confidence in the defensive operation of Busan.
However, on the way back, while thinking about the map of the Korean Peninsula, Liu Yiyuan fell into deep thought.
"Where are we?"
"We'll reach Jeju Island in twenty miles."
Liu Yiyuan hurriedly said: "Don't go back for the time being. Turn the ship around and go to the north."
The people below didn't know why, but since he gave the order, everyone had to obey it.
The sailboat turned and turned northwest along the southern tip of the Korean Peninsula.
It took more than half a month to go there.
When Yoo Il-won returned to Jeju Island, he had become unshaven and unkempt, but his spirit was very high.
He didn't bother to rest and wrote a report himself.
"On Attack and Defense on the Korean Battlefield"
"Send this report back to the headquarters immediately. It must be handed over to the commander-in-chief."
Regarding the Korean battlefield, Liu Yiyuan had new ideas.
This is a big plan, full of risks. If it succeeds, the benefits will be huge.
He looked in the direction of Shandong, wondering if the commander who was younger than him would approve his plan?
Shandong, headquarters.
After receiving Liu Yiyuan's report, Zuo Mengeng turned over it over and over, reading it line by line many times.
Liu Yiyuan's battle plan shocked everyone except him.
No one knows that a similar plan has been brewing in his mind for a long time. But he can't guarantee whether this plan will be feasible in this era?
Now Liu Yiyuan not only sent the report, but also went to the site to investigate in person and gave a guarantee of feasibility.
In full view of everyone, the decision-making power was placed in Zuo Mengeng's hands.
As time passed day by day, Liu Yiyuan, besides making constant preparations in Jeju Island, was waiting for Zuo Menggeng's reply.
But there was no response for more than ten days in a row, which made him a little discouraged.
Could it be that the high command chose a prudent plan?
Just when he was feeling depressed, two groups of troops arrived at Jeju Island at the same time.
One is the headquarters of the 1st Marine Division that Zuo Hua personally transported.
According to the original plan, the force executing the defense of Busan was the 1st Marine Division.
The overall transfer of more than 40,000 people is a very cumbersome procedure. However, the division headquarters can be put in place in advance to coordinate with the headquarters.
The other group of people is even more surprising.
Seeing Zhang Yan, Zuo Dai, Bai Xiaoqi, Le Xinfeng, and Huang Long coming together, Liu Yiyuan was a little confused.
Zhang Yan did not reminisce about the past, but read out the order from the headquarters in front of everyone.
"According to frontline reports, the North Korean combat plan has been revised. It is planned to establish the Eastern Group Army Headquarters. Chief of General Staff Liu Yiyuan is hereby appointed as the Commander-in-Chief of the Eastern Group Army. Zhang Yan, Minister of Logistics Department, Zuo Dai, Minister of Equipment Department, and Zuo Hua, Minister of Navy
, Zuo Yong, commander of the 1st Marine Division, and Bai Qi, commander of the 4th Marine Division, are deputy commanders-in-chief and are fully responsible for subsequent operations."
When they heard this appointment, everyone was in an uproar.
The Shandong New Army has fought many times, but never before has it dispatched so many senior generals and formed a joint command like this one.
Liu Yiyuan accepted the order, but also noticed something fishy.
"Minister Zhang, what is the so-called consensus of this army group?"
Before Zhang Yan came here, he had received all the instructions and explained them to everyone on the spot.
"According to your combat plan, the troops invested this time are no longer only the Navy and the First Marine Division, but also include the Third Division, the Korean Rebels and two militia groups. The total strength will exceed 100,000 people. Because of the affiliation of each unit
It was different from the original. This time we are on the same battlefield, so we need to reorganize it. The commander named it the Eastern Group Army, and we are the central command system."
An electric current surged throughout his body, making Liu Yiyuan feel comfortable all over.
"Commander agrees with my plan?"
Zhang Yan laughed.
"Otherwise, why did you mobilize so many elite soldiers and generals?"
The two of them talked happily, but Tang Wenhuan instinctively felt that something was wrong.
"Chief of the General Staff, Minister Zhang, what happened? Isn't it our First Marine Division who is in charge of the operation? Why is Bai Xiaoqi here too?"
Bai Xiaoqi was nearby, and he was shocked when he heard this. Without saying a word, he raised his foot and kicked him.
"You bastard boy, you're not big or small, you're looking for a beating, right? You can also call me by my first name? Besides, my name is Bai Qi, not Bai Xiaoqi."
Tang Wenhuan jumped casually without being kicked by Bai Xiaoqi.
"We are the same age, why are you pretending to be so big?"
Bai Xiaoqi was breathing heavily from his nostrils.
"The same for military ranks?"
He was a lieutenant general, while Tang Wenhuan was only a major general. The distinction between them was very obvious.
Tang Wenhuan's words were full of sourness.
"What's so great about a lieutenant general? Wait, who won't be a lieutenant general in the future?"
Good guy, when he said this, most of the people present stared at him.
Because many of the generals present were lieutenant generals.
Tang Wenhuan sensed something was wrong and quickly shrank his head and hid behind Zuo Yong.
Since he is his subordinate, Zuo Yong must protect him of course.
"Chief of the General Staff, are there any changes in the plan?"
After talking and joking, Liu Yiyuan was filled with pride as he looked at the star-studded generals gathered in front of him.
"That's right, this time... let's play something big."
