Fighting is both the cruelest struggle and the most profound knowledge.

Participants at different levels have different interpretations of war.

For the campaign commander, during the campaign planning stage, we must attach great importance to tactical means, and use the tactics to estimate the progress of the campaign and determine the campaign implementation method; when the campaign implementation stage, we pay more attention to various coordinated data, grasp the progress of the campaign, and decide whether to adjust the campaign implementation method.

Among the many factors that affect command and decision-making, logistics support and troops' combat effectiveness are the most important.

The war is the logistics!

Due to the influence of logistics support, the combat plan of each battle has been adjusted several times since the first battle, and the third battle has been most obviously affected. In order to meet the needs of logistics support, in addition to launching the "Jeju Island Battle" in advance, he also gave up the combat operation of attacking and opening the city, and taking the capture of Incheon Port as the first major goal of the battle.

After the Incheon Port was captured, a new problem: it has emerged.

The combat consumption of the 38th Army, 39th Army, 77th Army and the five mid-assault brigades exceeded expectations, especially the consumption speed of ammunition was far greater than the pre-war forecast. The problem before Pei Chengyi was that as the 38th Army continued to advance south, the 39th Army either waited for the arrival of the transport fleet at Incheon Port, or turned the gun to attack and opened the city. The combat materials stored on the front line could not support the 39th Army's attack on Seoul; if they wanted to attack Seoul immediately, not only did the 38th Army temporarily stop the attack, but they also had to dispatch the navy to provide firepower support to the 39th Army, causing the 77th Army to lose its main support force.

For Pei Chengyi, choice is not difficult.

The political significance of siege is far greater than the military significance. Sooner or later, the difference between attacking Seoul is not very different from attacking one day earlier.

The military's fighting power has a greater impact on Pei Chengyi.

The performances of several participating troops made Pei Cheng feel "surprised". Whether it was the "large-scale deep assault" of the 38th Army and the "focused attacks" of the 39th Army and the "large-depth rapid assault" of the 77th Army and the "large-depth rapid assault" of the 77th Army and the "large-depth rapid assault" of the military and the prestige of each army and the army.

The problem is that officers and soldiers are full of flesh and blood, not steel machines.

If the 39th Army turns around and attacks and opens the city, it will definitely have an impact on the combat operations in attacking Seoul.

At this time, Pei Chengyi needs to decide whether to let the "reserve team" play.

On the evening of the 12th, Pei Chengyi and Xiang Yinghui spoke on the phone and solicited opinions from the Chief of Staff.

Xiang Yinghui's answer is very simple. As the front-line commander, Cheng Yi has the right to mobilize all participating troops, and there is no need to ask the General Staff on tactical issues.

With Xiang Yinghui's support, the problem becomes much simpler.

On the night of the 12th, Pei Chengyi made major adjustments to the deployment of the battle.

The 395th and 396th Brigade of Kaicheng, which had been besieged Kaesong, the 27th Army stationed in Jinchuan, and the 611th Army stationed in Haizhou attacked Kaesong before 2:30 am on the 13th. Because the transport fleet will arrive in Incheon to fight Seoul on the night of the 13th, the combat operation of the war to fight Seoul will start at 1 am at the latest, so Pei Chengyi limited the time for the "Kaicheng offensive and defensive battle" to 30 hours. In order to provide sufficient fire support for the offensive troops, let the Air Force and HNA concentrate their efforts to bomb the Korean military positions in Kaesong, Pei Chengyi will, in addition to the c3911th Brigade, the c392nd and the brigade (the number of the artillery brigade is added before the number of the army), all six other direct artillery brigades on the western battlefield will be put into offensive operations.

There are 6 artillery brigades, with a total of 1c0c~there are large caliber howitzers and long-range rocket launchers.

Because Haizhou Port under the control of the 611th Army, it had undertaken the heavy responsibility of maritime transportation long before the Third Battle, so the artillery was not short of ammunition and drug resources.

The artillery fire was prepared for 3 hours starting from 23:30 on the 12th!

There is no way to use such fierce artillery fire to open the way for the offensive troops.

As the front line city for the north-south confrontation, it has always been the most important military stronghold on the 38th parallel. Before being occupied by the South Korean army, North Korea spent decades to build Kaicheng into the world's most solid "military fortress".

Long before joining the war, the Military Intelligence Bureau concentrated its efforts to collect information related to the deployment of Kaicheng defense.

According to the information revealed by North Korean generals and senior officers who fled to the Republic, Kaicheng has a "three-dimensional defense system of upper, middle and lower". At the top are various buildings. All buildings in the city are built according to military standards, and are integrated into one through underground tunnels. The defense forces can quickly transfer in underground tunnels and use solid buildings to fight offensive forces. In the middle is a complex road traffic system, with roadblocks or trenches at each important intersection, and sniper points and anti-tank fire points on both sides of the road. Some

Important roads also have minefields. Relying on buildings on both sides of the road, the defense forces can block a hundred in the city. At the bottom is a three-dimensional underground tunnel system like a spider web. The total length of the tunnels in the city alone exceeds 150 kilometers. In addition to the well-connected tunnels, there are underground military camps that garrison troops, underground warehouses that store materials, underground reservoirs that accumulate drinking water, and even underground hospitals and underground cinemas. Relying on underground tunnels, not only can 10,000 officers and soldiers be stationed, but they can also hold on for several months!

In the words of some Korean generals, if the Korean army had not lost unified command too early, the Korean and American coalition might not have been able to conquer Kaicheng in the first half of the year.

Various reconnaissance intelligence shows that the South Korean army made full use of the North Korean army's defense system.

Liu Zongchun was still commanding the Korean army in Daejeon. Although the morale of the Korean army was low and the fighting spirit was sluggish, it was far from the point of losing unified command. If the Republic Army hit a wall in Kaicheng, it was likely to boost the morale of the Korean army and restore the confidence and determination to continue fighting.

It is precisely because Pei Chengyi bypassed Kaicheng during the battle decision-making stage.

Go back and attack the city to open, the problem still exists.

No matter what era, attacking closely guarded military fortresses is the most troublesome thing for the attacking side.

US Army Lieutenant General Brooke even claimed that the Republican team can only use tactical nuclear weapons to capture Kaicheng!

According to Xiang Yinghui's recollection after the war, if Kaicheng encountered difficult troubles, the army would really be able to drop a tactical nuclear warhead in Kaicheng.

After the fierce artillery preparations were completed, two combat brigades of the 9th Army took the lead in launching the attack.

Fire support has not stopped. According to the requests of the front-line offensive troops or the tactical intelligence provided by the unmanned reconnaissance aircraft, the artillery and aviation forces continuously provide support to the offensive troops.

That's it, the first round of offense still encountered great trouble.

The 39511th Armored Battalion, which was the first to enter Kaesong, was stubbornly blocked by the South Korean army after entering the city for about 3 kilometers. In the end, it had to retreat under the cover of artillery fire. The frontal battle lasted only 15 minutes, and a total of 32 officers and soldiers of the battalion were killed, 127 were injured, and 12 tanks and 9 infantry fighting vehicles were destroyed.

After using firepower to repel the enemy, dispatch reconnaissance to regain the bodies of the fallen officers and soldiers, the ground attack temporarily stopped.

At 4:15 am on the 13th, Pei Chengyi called the Air Force Headquarters and dispatched strategic bombers to destroy Kaicheng's underground defense system with all means.

Fortunately, this was an order issued by Pei Chengyi, otherwise the Air Force would really be able to use tactical nuclear weapons.

In addition to tactical nuclear weapons, the best weapon to deal with underground targets is the heavy drilling bomb.

At 5:252, the h-99 with a special bomb was taken off from the strategic air force base.

The so-called "special bomb" is actually a "super heavy guide bomb" that uses a 203mm howitzer barrel as a bullet body to load insensitive explosives and delay time fuses, then installs a warhead made of high-strength alloy to seal the tail of the bullet, and finally installs a "super heavy guide bomb" with a guidance control system and a pneumatic control rudder surface.

If thrown from an altitude of 18,000 meters, this "super bomb" weighing 45~: can penetrate 9 meters of soil or rocks before detonation. The accuracy of the laser guidance device is within 3 meters, which is enough to deal with underground targets hidden in the city.

The 12 bombers carried a total of "special bombs".

There are only 50 such bombs in the arsenal of the Republic, and they were manufactured by the military factory after the South Korean and American coalition forces occupied Kaicheng.

Fortunately, a senior Korean military officer who was once in charge of Kaesong's defense did not forget to bring the military map of the Kaesong underground tunnel system when he fled to the Republic.

With this map, bombing has become much easier.

The front-line staff didn't take much time to determine the most worth bombing underground fortifications, which was the most worthwhile bombing, and confirmed the exact location of these targets.

At 6 o'clock, the first H-99 dropped a "special bomb" over Kaesong.

Because of limited ammunition, before the second H-9 dropped the bombing, the unmanned reconnaissance aircraft and the kz-199 first confirmed the bombing effect. If the ground at the blasting point was not obviously collapsed, it proved that the underground warehouse or underground garrison site was needed to be bombed. Otherwise, Pei Chengyi would also send special forces to confirm the situation.

Subsequently, the other 11 H-9s dropped bombs in turn.

After each H-99 bombing, Pei Chengyi asked the front-line troops to confirm to ensure that the bombing can achieve the best results.

It was not until 7:35 that the last H-9 dropped a "special bomb".

Although it took about 3 and a half hours to do this, the results were very significant.

According to many surrendered Korean troops, after the bombing was over, the Korean army would no longer dare to stay in underground fortifications, and even the Korean army command was moved to a solid building. If there was no absolute necessity, the Korean army would rather take the risk of maneuvering on the ground than use underground tunnels.

After occupying Kaicheng, the 27th Army, which was responsible for cleaning up the battlefield, confirmed the bombing effect again.

Among the bombed underground targets, one was completely destroyed and two were seriously damaged. The most serious damage was 211 underground warehouses and 19 underground garrison sites. The 27th Army dug out at least 3,000 unidentified corpses from the ruins, and later the Korean army found thousands of incomplete corpses in the bombing ruins.

This is the cruel side of war!

This bombing fundamentally disintegrated the morale of the South Korean army.

As soon as dawn was dawn, the ground attack began again.

Although there are still many Korean troops who are fighting stubbornly, most of the Korean troops handed over their weapons to the attacking Republic team after a limited resistance.

It’s not that the Korean army has no ability, but that they don’t have the confidence to continue to resist! (To be continued,)
Chapter completed!
