At this time, Japan launched the second battle of the Yalu River, which had lasted for 15 days, although the Japanese army had already entered the war in full force on the fourth day of the war, and was no longer contained by the South Korean army as cannon fodder, and had also successfully landed on the west bank of the Yalu River many times, but under the strict defense of the People's Army, it was still unable to establish a solid beachhead on the west bank of the Yalu River.

In fact, in order to break through the KPA's defense line on the Yalu River, the Japanese army also tried all means; before attacking, the Japanese army did not hesitate to risk the danger of its artillery positions being attacked by the KPA, and launched a fierce artillery bombardment of the KPA's positions to provide fire cover for the attacking troops; moreover, in order to establish a solid position on the beachhead as soon as possible, the Japanese army even ordered each soldier to bring a bag of sand and soil to pile up the sand as a bunker as a cover after landing on the shore; and also sent engineers to erect a pontoon bridge over the Yalu River in the face of the KPA's firepower.

However, the People's Army has established a perfect tunnel position defense along the Yalu River, the Japanese artillery is basically small and medium-caliber artillery, and is limited by the precision strike of the People's Army, the People's Army's two 200 mm caliber self-propelled guns drive back and forth on the lane behind the position, according to the position of the Japanese artillery position provided by the drone, constantly firing and shooting, destroying several Japanese artillery positions in a row, forcing the Japanese army to frequently change the position of the artillery position, and it is unable to continue the shelling, so the lethal effect on the position of the People's Army is not great。

The Japanese soldiers landed with sandbags, and they could indeed quickly arrange bunkers on the shore, but this kind of bunker defense rifle and machine gun shooting still had a certain effect, but the defensive effect on the artillery was very limited, and the mortar of the People's Army could use a large curve ballistic shooting, and the artillery fire was very intensive, and the array of artillery fire covered the shooting, which could basically annihilate all the enemy. Although the KPA's combat plan was not to annihilate the Japanese troops in the river, but to put them ashore to annihilate, the Japanese army would never be allowed to build a pontoon bridge on the Yalu River, so as long as the Japanese pontoon bridge was halfway erected, the KPA would concentrate artillery fire to destroy the pontoon bridge.

As a result of more than 10 days of fighting, the Japanese army suffered heavy casualties, with more than 60,000 casualties, including about 35,000 casualties of the South Korean army and 26,000 casualties of the Japanese army.

Of course, the efforts of the Japanese army in these days were not all useless, at least the large number of mud and sandbags transported to the west bank of the Yalu River, plus the corpses of the dead soldiers, also provided a lot of cover for the later Japanese attack, which was much better than when the war began. By the 13th day, the Japanese army had finally withstood the KPA counterattack on the beachhead on the west bank of the Yalu River and established a small position.

When the commander of the Japanese army, Gentaro Kodama saw this, he immediately ordered to hold this hard-won beachhead at all costs, so the Japanese artillery desperately fired at the KPA position near the beachhead, providing fire support for the subsequent landing of the Japanese army and expanding the position, and even did not hesitate to become the target of the KPA's self-propelled artillery attack, while the Japanese soldiers rowed hard to reinforce the beachhead, and at the same time Kodama Gentaro also ordered the Korean army to attack from both sides of the beachhead, contain and attract the KPA's attack, and also sent engineers to erect pontoon bridges。

As a result, after two days and one night of fierce fighting, the Japanese army paid the price of four artillery positions and three pontoon bridges destroyed by the People's Army, expanded the beachhead position to a position of about 1,500 meters horizontally and more than 400 meters deep, and used mud and sandbags and dug a small number of trenches to build simple but relatively complete fortifications, and stationed about two wings of troops.

Kodama Gentaro also breathed a sigh of relief, with this position, the Japanese army also had a foothold on the west bank of the Yalu River, and then gradually expanded its advantage, and there was great hope for breaking through the People's Army's defense line on the Yalu River. But at this time, Kodama Gentaro received a report from the Quartermaster Department that the Japanese army had less than 30% of the ammunition left. This is already a near-danger number, and under normal circumstances, the Japanese should immediately stop the offensive and replenish ammunition. But now the Japanese army has no ammunition to replenish.

Kodama Gentaro's heart is also full of contradictions, seeing that he is about to achieve victory, but at this time the ammunition is insufficient, and he is about to fail, Kodama Gentaro's heart is naturally unwilling, and once the army is withdrawn, the Japanese army will also completely lose this war, so the goal of promoting peace with war can no longer be realized. Therefore, Kodama Gentaro was also weighing in his heart, whether to gamble, bet the last 30% of all the ammunition, attack the defense line of the People's Army with all his might, and strive to completely break through the defense line of the Yalu River of the People's Army in one fell swoop.

This is naturally quite risky, not to mention whether the remaining last 30 percent of the ammunition is enough to support the Japanese army to completely break through the Yalu River defense line, even if it is successful, the Japanese army will no longer have the power to resist, so the people's army only needs to launch a counterattack, and the Japanese army can completely return the Japanese army to its original shape, but if the Japanese army does not gamble on this and withdraws its troops and strikes the war like this, then it is meaningless to start this war, and Japan will not have any bargaining chips to play with the East China government in the subsequent negotiations? This decision is indeed not easy to make, and Kodama Gentaro thought about it again and again, but did not make a final decision.

But at this time, the People's Army finally launched the Zhennanpu landing battle.

At this time, the 1st Marine Division had been assembled for six days, and after a short rest, the soldiers of the 1st Division had basically recovered their mental and physical strength and were able to participate in the landing operation in good condition. And just two days ago, the 2nd Marine Division and two reserve regiments also returned to Qingdao, but they did not have time to rest, and they had to immediately enter a new battle.

Compared with the previous two landing battles, the preparations for the Zhennanpu landing battle this time were the simplest, and Luo Yue only obtained the hydrological data of the sea area near Zhennanpu and the Japanese army's shore garrison three days before the attack.

However, Luo Yue is still full of confidence in this battle, this is not Luo Yue's blind confidence or arrogance, but according to the results of the People's Army's reconnaissance of the Zhennanpu coast, the Japanese army's defense of the Zhennanpu coast is quite lax, and there are not a few batteries on the entire coast except for the port, and there are not many troops stationed, it is estimated that there is only about 1 regiment, and the marines pass through Lushun, After the two landing battles in Vladivostok, Luo Yue also accumulated considerable experience in landing battles, and based on these factors, although the preparation time for this landing battle was short, Luo Yue still had the confidence to do so.

After all, the Korean Peninsula is surrounded by the sea on three sides, the coastline is too long, and there are too many places where it can land, and the Japanese army is now limited in strength on the Korean Peninsula, and it cannot fully trust the South Korean army, so it can only give up coastal defense, of course, Kodama Gentaro did not expect that the People's Army would land in Zhennanpu, Bi Jing's landing war in this era is still a new concept, although the People's Army has successfully landed twice, it still did not arouse Kodama Gentaro's sufficient caution.

On November 10, 1905, Luo Yue led the fleet from Qingdao to Zhennanpu, this time the fleet was divided into the Sanya ship as the flagship, including the battle detachment, the armored cruiser detachment, and the newly established Fifth Cruiser Detachment, the Fifth Destroyer Detachment, plus 4 Marine Corps fire support ships, 4 landing ships, and 8 transport ships.

Zhennanpu is about 500 kilometers from Qingdao, and the fleet departs at 6 a.m., travels at a speed of 12 knots, and at about 3 a.m., reaches the sea area at the mouth of the Datong River.

Although Zhennanpu is a seaport, it is not actually near the sea, but is located about 20 kilometers east of the mouth of the Datong River, and the sea ships must sail into the Datong River to reach Zhennanpu, but the river surface of the Zhennanpu River section is very wide, reaching 2000-3000 meters, and the general large sea ships can sail into, so from the geographical environment, Zhennanpu and Shanghai have certain similarities.

The landing tactics formulated by Nagak were to have the armored cruiser detachment, the 5th destroyer detachment take two landing ships, and two transport ships sail in along the Taedong River, occupy the port of Jinnampo, and then attack Pyongyang, and the other fleets will land on the seaside, and if the landing battle to attack Jinnampo is unfavorable, then launch an attack from behind Jinnampo, attack from the back of Jinnampo, attack by sea and land, take Jinnampo, and then go straight to Pyongyang.

So the fleet was immediately divided into two here, led by the armored cruiser Chitu, sailed into the Datong River, while the other team landed on the seaside, and Luo Yue took command on the Sanya ship.

The KPA chose a seaside landing site on a beach, with no military garrison nearby, only a few small fishing villages. Therefore, the KPA did not even prepare for the shelling, and the two landing ships left the fleet and headed for the shore.

Half an hour later, a landing ship rushed to the shore, the floodgates opened, and soldiers poured out of the cabin and set foot on the Korean Peninsula. However, the second landing ship ran into trouble and ran aground on a reef about 300 meters from the shore, which was also caused by insufficient time for preparation and insufficient detailed hydrographic reconnaissance.

However, the KPA did not panic because of this, and the commander of the second landing ship immediately decided to launch at the stranded position and swim ashore. So the soldiers took the water rescue ring, jumped into the icy water, swam to the shore with all their might, and in time the two cruisers drove over, threw ropes, tied the second landing ship, and dragged it back into the sea from the stranded position.

This small accident allowed the first batch of KPA to land beyond the scheduled 40 minutes, but this kind of accident was inevitable on the battlefield, but fortunately after the first batch of troops landed, nothing else happened, and after a short period of rectification, the troops of the two battalions quickly dispersed along the beach, occupied the important position, and held this beach. And the two landing ships have also been loaded with the second batch of landed troops and sailed to the shore.

Both groups of troops landed successfully, and the landing operation on the seaside was also mostly successful, so the third group of troops landed no longer the army, but the engineering troops and a batch of assembled materials, ready to build a simple trestle bridge on the shore beach, so that the transport ships could land directly on the shore.
