Because the two military advisors of the Kuroda family are indeed powerful, Shimazu Iehisa immediately told his brother his thoughts as soon as he realized this, that is, Shimazu Yoshihisa, the head of the Shimazu family, hoping to attract his brother's attention. After all, in which aspect of their opponents compares with themselves, the Shimazu family is definitely at a disadvantage.

Shimazu Iehisa has always had no last resort, so after hearing his words, Shimazu Yoshihisa did not dare to slack off, and immediately followed his brother's advice and immediately sent someone to his rear to check if there was any unusual information.

As a result, the Shimazu family didn't check it, but after checking it, he learned that the Shimabara Castle behind him had been captured by the Kuroda family, and the Kuroda family still had a lot of defenders, because they couldn't be seen at close range, so the specific number was unknown, and the preliminary estimate was no less than a thousand.

And it is located in the middle of the confrontation between Shimabara Castle and his own army and the Kuroda family, and in that location is the new inner castle where the Shimazu family is now located, and the castle and the surrounding land are now under the watchful eye of the Kuroda family.

At this time, Shimazu Iehisa finally knew that Shigeharu Takenaka and Kai Soun were powerful, and he originally wanted to use Shigeharu Takenaka's attack method to carry out a fishing ambush in the battle, hoping to defeat the attack of the Kuroda family. The Kuroda family didn't come to attack, and at first he felt that he was given a chance to breathe here, but now he realized that he was still too young.

Not only the Shimazu family, but who would have thought that the two of Takenaka Shigeharu and Kai Soun might have seen through the Shimazu family's ideas and had corresponding countermeasures, which led to the current situation.

What the Kuroda family did was actually very simple, Shigeharu Takenaka led the army to attract the attention of the other party, and created the illusion that the number of the army had not decreased. It is composed of the relatively adventurous Kai Zongyun, with a small number of partial divisions, mainly composed of the men and horses of the Aso family and the Amakusa Five.

With such a group of men and horses, escorted by the navy of the Amakusa Five, they made a detour to the rear of the Shimazu family's army and landed, and then seized the important Shimabara Castle behind the Shimazu family, so as to cut off the entire Shimazu family's back road and trap the Shimazu family's army in the current main battle.

As we mentioned earlier, Shimabara Castle is located at the southernmost tip of the peninsula, and it is a castle built in a place that is easy to defend and difficult to attack, and it is considered a large castle in terms of area. To the south, west, and east of it are cliffs and seas, and if you want to attack, you can only attack from the north. In other words, there is only one road leading to the city, and it is precisely because of the inconvenience of transportation that this road was cut off by Kai Zongyun, which completely cut off the connection between Shimabara Castle and the outside world.

After cutting off the connection between Shimabara Castle and the outside world, the Kuroda family attacked it, Shimazu Yoshihisa thought it was safe here, and he had to go all out in the face of the Kuroda family, so Shimahara Castle only had more than 50 defenders, and they were basically old, weak, sick and disabled, not to mention defending the city, dissatisfied with the surrender of Kaejo, it was already very loyal to the Shimazu family.

The 1,500 men on the Kuroda family's side were actually basically miscellaneous troops, and even so, Kai Muneun only ordered a round of attacks, and the samurai of the Aso family, Katayama Goro Guard, approached directly, and with his own martial arts, he was the first to rush into the city, not only gaining some merit, but also successfully opening the castle gates.

There weren't many defenders in Shimabara Castle in the first place, but now the Kuroda family broke the city as soon as they came up, and in the end, most of the fifty defenders surrendered on their knees, which made the countrymen and lords who wanted to mix up some merits depressed, why didn't you resist more?

Now Shimabara Castle has fallen into the hands of the Kuroda family, and the Kuroda family is now confronting the Shimazu family here, and there are more than 16,000 people, with this number of people to want to leave the Shimazu family all here, although it may not be completely realized, but in the entire rear of the Shimazu family, it has been threatened by the Kuroda family's special forces, and the situation that Shimahara Castle is captured, it also means that the Shimazu family has actually faced a situation of being flanked by both sides to a certain extent, which is a very difficult situation for the Shimazu family.

In this case, even Shimazu Yoshihisa felt that there was not much chance of victory in the face of the Kuroda family, and even many samurai of the Shimazu family once again showed their despair and willingness to die. They also expressed their determination to Shimazu Yoshihisa, and were willing to fight to the death for the Shimazu family and the Kuroda family, even if they died here in the end, it would be considered to fulfill their name as samurai.

Since there was not much to think about, Shimazu Yoshihisa agreed to their request and personally rushed over with the entire army of 3,000 people against the Kuroda family.

This situation was expected by Shigeharu Takenaka a long time ago, and as the head of the Kuroda family, he was not afraid at all, because the Kuroda family not only had an advantage in numbers, but also in morale, equipment, and various other preparations, which was an absolute advantage for the Kuroda family.

To tell the truth, the people in the middle of the mountainous areas in the western part of Harima Province are very good soldiers, because they have been working and hunting in the mountains for many years, and they are already physically strong, and they have developed a very instinctive sense of battle in the subsequent battles, which is why the Kuroda family has greatly strengthened their strength after winning the entire western mountainous area of Harima Province.

At that time, many of the soldiers of the Kuroda family came from the mountainous areas in the western part of Harima Province, and it was the courage of these mountain people that brought the Kuroda family enough combat power to promote the Kuroda family's rapid progress.

Compared to the people in the western mountains of Harima Province, the people were poorer and the land was poorer, and it was obvious that it was easier to produce high-quality soldiers.

For example, many of the soldiers of the Shimazu family today are the elite soldiers brought by the Shimazu family when they left Satsuma Province, or they are a group of newly recruited soldiers from the people of Satsuma Province who have been following from Satsuma Province at that time.

These people may have a big gap between them and the Kuroda family soldiers in terms of equipment and combat awareness, but they have a courage that is not afraid of death, a kind of momentum that is not afraid of sacrifice for their own master, and it is generally difficult to embody such a momentum, and now in order to survive, in order to be able to defeat the Kuroda family, they have to play their most powerful combat power in this very desperate situation.
