Soon after Gao Shanji "recaptured" Seoul, the main force led by Song Qing and Yi Ke Tang A also moved south to Seoul, causing the total strength of the Qing army in Seoul to soar to nearly 30,000.

Although the front advanced significantly, because the Qing army relied entirely on sea transportation for supplies, and Seoul was next to Incheon, the largest port in North Korea, the logistics supply of the army was more adequate than when it was in Pyongyang.

With such a material foundation, and because the Japanese army retreated without a fight, it was inevitable that Song Qing and Yiketang Adu would be a little eager to seek merit, so the Qing army in Seoul did not repair for long before moving south, wanting to destroy the Japanese army in southern Korea and completely solve the Korean war.

The initial stage of the march was relatively smooth, and the Qing army did not take much effort to take several major cities in Jeolla Province, the most important grain-producing area in Korea, but after the eastward march into Gyeongsang-do, there were no longer nearby ports available, and the Qing army's advantage in logistics and supply was gone, and the defect of not being good at white-knuckle warfare was completely exposed.

To make matters worse, at this time, the Japanese army in Pusan had already replenished a large number of soldiers, and the total strength of the army had soared to more than 40,000 people, more than twice the size of the Qing army

In just a few days, the Qing army was defeated and collapsed on the whole line, if it were not for the fragmentation of the mountainous and hilly terrain that was not conducive to pursuit, if it were not for Gao Shanji, who was sent to escort grain and grass (Song Qing and Yiketang Ah did not want Gao Shanji to make great contributions again), Gao Shanji led his troops to respond in time, and the main force of the Qing army that entered the dynasty would have been wiped out.

And even so, the Qing army still suffered the heaviest losses since the beginning of the First Sino-Japanese War, returned to Seoul to count the number of people, and found that there were only more than 12,000 left, less than half before the south

However, if it weren't for the fact that they swept away the Korean (pro-Japanese) puppet troops along the way who had swarmed up after the Battle of Gongju, the Donghak rebel army, which had suffered an unprecedented heavy blow not long ago, would probably not have had a chance to ease its breath at all.

After learning about the strong combat effectiveness of the Japanese army, Jeon Hyun wisely gave up the idea of a head-on battle with it, and used the guerrilla tactics of frequent attacks by small units to create trouble for the invading Japanese army, which posed a huge threat to the Japanese army's land supply lines.

For the Japanese army, although the defeat of the main force of the Qing army is worth rejoicing, because it was a field victory, the supplies captured by the Japanese army were relatively limited, and the place of engagement was far away from Seoul. Even if they were dealing with the Donghak rebels in Jeolla Province, they would face the problem of supply difficulties.

What's even more troublesome is that the relieved rebel army has become more cunning than before, and even if the Japanese army has increased its strength now, it will be difficult to completely solve this serious problem in a short period of time, so I am afraid that it will be impossible for the Japanese army to return to Seoul again for a long time

On the other hand, the Qing army, which had suffered heavy losses, did not have the strength and courage to launch another offensive, so the Korean battlefield was at a stalemate for a while.

Such a situation was not a bad thing for the Qing army, because it made it impossible for the Japanese army to give full play to its advantages in (available) strength and combat power, and it could only compete with China in terms of material consumption and supply efficiency, which was not good for it.

According to the Qing generals, as long as the Beiyang Naval Division continued to control the sea supremacy in the Yellow Sea, this stalemate would continue until the Japanese were forced back to the negotiating table.

But what they didn't expect was that before the spring flowers bloomed, there was a bad news from the north that made everyone stunned, "What? Pyongyang fell? ”

Because he had formed ties with almost all the senior generals in the end of the Edo War, and he also liked to expose scars and offend people everywhere, although the former No. 1 shogunate general in the shogunate army was forced to be reactivated by the helpless Meiji government after the outbreak of the Southwest War, but he was never really reused, and was not promoted to major general until the eve of the First Sino-Japanese War, and served as the brigade commander of the 10th Infantry Brigade, and was given the opportunity to lead troops again after many years.

Long before Yama Yama Youpeng made up his mind to lead the army to retreat south, Tsumi Naowen realized that the Japanese army had fallen into a predicament that could not be extricated from relying on its own strength alone, with rich war experience and his own study of Western military theories over the years, he came up with a way to break the situation, although it was very risky, but as long as it was really successful, it would be able to completely break the dead situation on the Korean battlefield and wipe out the Qing army in Korea.

Yama County Youpeng was worried about the stalemate of the war situation at that time, and considering that even if the plan failed, he could afford the loss of thousands of people, and he could get rid of the thorn of Tachimi Shangwen by the way, so he agreed to his proposal and let him go to Wonsan to preside over the plan.

When Tachimi Shangwen risked being intercepted by the Beiyang Naval Division and arrived at Wonsan by sea, the Japanese army base camp had already reorganized the thousands of Japanese troops there, except for an infantry brigade stationed at Wonsan Port to ensure supplies and the rear road, the rest of the troops were transferred to the unified command of Limi Shangwen, with a total strength of more than 5,000, equivalent to a fully equipped infantry brigade, or the kind that was greatly expanded after the outbreak of the war.

Obviously, no matter how much he disliked Tsumi Shangwen, in the current unfavorable situation, the decision-making level of the Japanese army base camp still gave him unprecedented power.

However, the ambitious Tatsumi Sang-moon did not immediately implement his plan, but first spent more than a month "suppressing the bandits", because if the anti-Japanese forces in the southern part of Hamgyong Province in North Korea were not cleared, the secrecy work would inevitably encounter great challenges, and once the action was leaked prematurely, the plan of the Tatsumi Sang-moon would fall short.

Fortunately, the work was not too difficult, and although there were many Donghakout-do believers in Hamgyong Province in northeastern Korea, it always lacked a leader who could convince the people, and the area was sparsely populated, lacked the sufficient population necessary for long-term resistance to the Japanese army, and was also an expert in guerrilla warfare, so it was quickly wiped out.

After sweeping away the hidden dangers, Tsumi Naomi selected the good health from the Wonsan detachment (due to the lack of adaptation to water and soil and the backward medical and health conditions, the Japanese Army suffered a lot of diseases in the First Sino-Japanese War, and more than 10,000 people died in history, which was several times the number of people killed in the war, among which the lack of vitamin B1 caused the most beriberi. More than 3,000 people formed a special unit, which the Japanese base camp called the "Ritsumi Detachment"
