Unlike the Botian detachment, Han Yunhua had long anticipated the enemy they were going to face, although Han Yunhua was a commander who knew history well, but after all, there were many historical truths buried in the dust, and it was impossible for him Han Yunhua to know everything that happened decades ago. However, Han Yunhua calculated after the outbreak of the Battle of Wuhan that he believed that the troops of the Inner Mongolia Military Region were most likely to meet the Japanese army's 6th Division, 16th Division, 106th Division, and Botian Detachment.

Out of his understanding of the Botian detachment, Han Yunhua was very sure that the Inner Mongolia Military Region was the first to confront the Botian detachment, after all, the Botian detachment, as the vanguard of the Wuhan battle, had fought almost all the squadrons in the five-month battle in history.

On October 4, Han Yunhua's department rushed to Hukou Fortress by train, originally according to Chen Cheng's opinion, Han Yunhua's department was asked to take a warship to Hukou, but Han Yunhua knew that now taking a warship was simply looking for death. Not to mention colliding with a Japanese warship, even if it is touched by a Japanese plane, it is also extremely dangerous. In addition, almost all the troops of the Inner Mongolia Military Region are men from the north, and few of them know how to be water-based, most of them are landlubbers, and once they fall into the water, there is still a way to live.

Although taking a warship is much faster than a train, Han Yunhua still decided to take a train with a slow speed and a high insurance factor to rush to Hukou. Along the way, although the train taken by Han Yunhua and others was bombarded by the diary, it was not in danger.

On October 8, Han Yunhua and others finally arrived at Hukou, in fact, Chiang Kai-shek and Chen Cheng knew that although Hukou Fortress is also called a fortress, it is far from being compared with Madang Fortress, whether it is terrain conditions or the construction of fortifications and firepower points, Hukou Fortress is not as good as Madang Fortress.

In the eyes of the high-ranking officers of the Kuomintang, once the Madang fortress was lost, then the Jiujiang Lake Estuary and other places in the upper reaches of the Yangtze River would be in no danger to defend, and the Hukou would sooner or later fall into the hands of the Japanese. Chiang Kai-shek sent Han Yunhua's troops to Hukou at this time, and his sinister intentions can be imagined. If the troops of the Inner Mongolia Military Region held Hukou, it was he Jiang who had the insight to defend such an important strategic place, regardless of previous suspicions, and Jiang should be the first to take the lead in this battle. If Hukou is lost, then it is the fault of the Eighth Route Army, which happens to be leveled with him in the Madang Fortress, and it is also the Eighth Route Army that has failed to live up to his expectations of Chairman Jiang, and he should give an explanation to the people of the world. Of course, this did not mean that there was no intention of consuming the Eighth Route Army, but these Han Yunhua didn't mind, after all, they came to fight devils when they went south, not to attend the banquet of the National Government.

When Han Yunhua arrived at Hukou, he did not transfer all the troops to Hukou Fortress and Hukou County, but only brought one regiment of Jiang Spruce into Hukou Fortress, and took over the defense of Hukou Fortress from the 457th Regiment of the 22nd Division of the Kuomintang 22nd Group Army. Han Yunhua also transferred one battalion of the artillery regiment and one battalion of the fire support regiment into the Hukou Fortress. At the same time, Han Yunhua transferred the 1st Battalion of the 88th Regiment, the 2nd Battalion of the Fire Support Regiment, and the 3rd Battalion of the Artillery Regiment to Hukou County, while other units were concealed outside Hukou and stood by.

Although Han Yunhua did not have a detailed plan to deal with the Japanese army, he knew that the Hukou fortress was in no danger, and if the density of troops was too large, it was likely to become a target for devils, especially the Japanese planes. Moreover, now the Japanese army already knows that part of the main force of Han Yunhua's department has arrived in Wuhan, but it has not known how many troops they have, so it can be said that the Japanese army is in the light and they are in the shadows, and the whole army takes this opportunity to yin the Japanese army once.

Sure enough, on the second day after Han Yunhua and others entered the Hukou Fortress, the main force of the Botian detachment arrived at the periphery of the Hukou Fortress and carried out a tentative attack on Han Yunhua's headquarters. But he was soon repelled by Han Yunhua's subordinates, leaving behind more than 200 corpses.

However, the Japanese army obviously did not give up its intention to occupy Hukou, and this part of the main force of the Hatachi detachment actually camped on a small hill not far from the Hukou fortress, preparing to continue the attack on the Hukou fortress after the arrival of a large force led by the detachment commander (brigade commander) Major General Hakuda Shigeichi. But no one expected that the squadron defending the Hukou Fortress that night would take the initiative to attack the Japanese troops stationed on the periphery of the Hukou Fortress, and it was a blatant attack.

At around 11 p.m. on October 9, the sweltering heat of late summer made it difficult for most people, including the Japanese troops who had just invaded the Yangtze River region. However, these were not a problem for the soldiers of the Potian detachment living in Taiwan, and after dinner, under the compulsory order of the officer, most of the Japanese soldiers took the initiative to enter the barracks to rest. ,

Until now, neither the national government nor the ** people know very well what the Potian detachment that suddenly appeared is the great god of that place. However, Han Yunhua knew that the vast majority of the soldiers in the Botian detachment were from Taiwan, and it was a mixed Sino-Japanese unit, and the establishment of the unit was at the brigade level. Although this unit is very tenacious in combat and has strong combat effectiveness, it has a very fatal loophole, that is, there is extreme internal disunity, and Taiwan's local soldiers are often bullied by purebred Japanese and have great resentment.

Moreover, the vast majority of Taiwanese soldiers were forced by the Japanese authorities, and the families of these soldiers were hostages in the hands of the Japanese, and once these soldiers made mistakes on the battlefield, not only the soldiers themselves would be punished, but also the families of the soldiers would be implicated. Although this method can arouse the combat effectiveness of Japanese soldiers, it cannot really arouse the combat and survival of the troops**.

According to Li Dayong's suggestion, Han Yunhua only needed to send a regiment of soldiers to launch a surprise attack on the Japanese army, and he could solve the battle within an hour and completely annihilate this small Japanese army with only more than 1,000 people. But Han Yunhua didn't do this, not that Han Yunhua didn't dare, but that Han Yunhua didn't look down on the more than 1,000 Japanese troops too much. Compared with the more than 1,000 people, Han Yunhua looked down on the more than 40 Japanese warships moored on the Yangtze River.

In the Battle of Wuhan, the Japanese army not only dispatched a large number of aircraft and ground troops, but also dispatched a large number of navies. The Third Fleet of the Japanese Army, which entered the Yangtze River to support the ground forces, was not the most combat-effective naval fleet in the Japanese Navy, on the contrary, it was incomparable with several other Japanese navies in terms of the displacement of ships and the firepower of the ship's guns. But now the target of the war is China, and the location of the operation is an inland river such as the Yangtze River. Compared with battleships and aircraft carriers with a displacement of tens of thousands of tons, a "tattered" navy like the Third Fleet has room to play. You must know that due to the restrictions of the Nationalist Government's operation and geographical conditions, large warships cannot appear in the Yangtze River.

Although the warships of the Third Fleet are very despised at sea, they are absolutely "giants" on the Yangtze River. The ships used by the Third Fleet were large ships such as battleships, but more often they were small ships such as cruisers, destroyers, frigates, torpedo boats, and gunboats. This fleet rarely shows up in foreign warfare, because such strength is inferior to that of the American and British fleets in Asia. But such a fleet is enough to deal with the Chinese Navy, which has only three or two kittens.

But now they are in Han Yunhua's eyes, in Han Yunhua's opinion, although the more than 1,000 Japanese troops are still delicious, they are far less attractive than the warships of the Third Fleet. It is still necessary to sneak attack the Japanese troops on the shore, only if the devils on the shore are hurt, the Japanese ships in the river will go crazy, so that Han Yunhua can also seize these warships.

Han Yunhua did not use the defenders in the Hukou Fortress, but used the two infantry battalions of the 88th Regiment and the three battalions of the Fire Support Regiment hidden in Hukou County, totaling more than 2,300 people, to launch a surprise attack on the Japanese infantry on the shore. The Potian detachment was invincible along the way during this time, and the Kuomintang army, whether it was at the regimental and brigade level or at the division level, was defeated by the Potian detachment without exception. A few days ago, a brigade was used to capture the Madang Fortress, which was guarded by an integrated army of the Nationalist Government and two local divisions. Therefore, the current Hatian detachment can be described as high-spirited, and even those Taiwanese soldiers who have been bullied by the purebred Japanese are full of arrogance and arrogance. Since the beginning of the war, the Japanese army has been attacking, and the Nationalist Government has been a passive defense, so the Hatian detachment never expected that the squadron ** on the opposite side would take the initiative to attack.

For the Hakuda detachment, the battle happened very suddenly, just as the great Yamato warriors were about to rest, without warning a cannonball fell on the side, although there were no heavy artillery shells, but it still caused a lot of casualties to the Hatada detachment, less than two minutes of shelling, completely caused the Hatada detachment to lose one-fifth, about 250 devils were killed and wounded, lost combat effectiveness. The reason for such a great result was entirely because the Japanese army was not prepared at all, and at the same time, most of the soldiers of the Japanese army were preparing to rest, and the density was relatively high.

The captain of the 3rd Brigade of the Harata Detachment, Kobayashi Jiro Nakasa, knew when he heard the sound of artillery that he was going to be attacked, and this group of hateful Shina people dared to launch a sneak attack on the heroic Imperial Japanese Army. While ordering the troops to organize a counterattack, Jiro Kobayashi reported to Major General Shigeichi Hada.

After receiving the telegram from Kobayashi Jiro, Major General Hakuda Shigeichi was also surprised, in his cognition, the squadron seemed to only hide in the strong pillboxes and fortifications and resist passively, how could it take the initiative to launch a counterattack, this is the unilateral tactics of the Chinese troops stationed at the mouth of the lake or the prelude to the major counteroffensive of the Chinese government, which made Major General Habata Shigeichi fall into deep thought.
