On June 9, 1560, the siege of Inmajo was officially completed.

Yesterday, when it was learned that the territory was occupied, Iio Renlong was forced to announce his surrender, and the Miura family and the Katsuyama family surrendered to the Asahina family and offered hostages, so that they were able to gather the scattered old troops and join the besieging forces. At present, the number of troops outside Yinma City has reached more than 4,000 soldiers, and the total number of troops exceeds 15,000. On the other hand, the Okabe family trapped in Yinma Castle had less than 1,500 soldiers left, and the total number was less than 5,000. A third of the more than 20,000 people in the towns outside the castle fled to escape the war. The rest ran to the side of the Asahina family. Yu Qiuping ordered his subordinates to help them build a simple residence next to the barracks for them to live in for a while.

When he learned that Iio Renryu, Miura Yoshiyoshi and Katsuyama Motomoto had fallen to the side of the Asahina family, Okabe Motonobu reluctantly stayed alone in the inner room for an afternoon. The surrender of the Ii family was due to their own miscalculation - they failed to realize that the Asahina family would attack Ii Valley Castle, which led to the arrest of the Ii family. And the surrender of these three families was largely due to military defeats. In just a few days, the situation was completely reversed.

Because of the unbelievable rapid march of that Yu Qiupei and the damn rumor that he left behind that "the Takeda family might attack", the Okabe family was in a big mess and put on that defensive layout that was not external to the inside, only to be split and broken by the Asahina Tai Dynasty from the middle straight into the core.

And now, Motonobu Okabe has no hope of victory at all. The morale in the city is low, the number is inferior, and what is even worse is the crisis of grain and grass.

The current time is just before the autumn harvest, the old grain is exhausted, the new grain has not been harvested, and the time of the year is the most scarce time of the year. Originally, Yinmacheng was the main city of Yuanjiang, and a lot of grain was always stored. However, due to Imagawa Yoshimoto's operation in Kamiraku a month ago, most of the stored grain was taken away by the army. What's even more unfortunate is that when retreating from Yoshida Castle, in order to ensure the speed of the march, Okabe Motonobu did not take away the huge baggage in Yoshida Castle, but only brought the necessary rations, and abandoned the surplus food in Yoshida Castle - which further aggravated the crisis of food shortage.

As the war approached, many of the residents of the castle town fled into the castle to take refuge, and the food became stretched thin, and the price of food in the castle doubled in two days. Nearly 6,000 people and more than 4,000 troops are now crowded into the city, and food is being consumed rapidly. Okabe Motonobu estimates that with such a grain consumption, if Yinmacheng persists for half a month at most, it may fall into a situation that he least wants to see. For this reason, he deliberately blocked the news of the food crisis in Yinmacheng, so as to stabilize the morale of the army and prevent the troops of the Asahina family besieging the city from knowing.

The only hope he had now was an envoy sent to mediate in Junfu City. The civil war between the two families has been going on for more than half a month, and Junfu City has still not reacted until now, which is really very abnormal. Although the outcome of the mediation may be very unfavorable to the Okabe family due to the failure of Okabe Masana - it is better than being trapped in Inima Castle.

"Damn the mole." Okabe Motonobu looked at the maple bird flag flying high in the east of the city, and scolded viciously: "The Imagawa family will be destroyed in the hands of you!" ”

On June 10, after the encirclement had been completely stabilized, Asahina Tai and Sena Shitoshi prepared to leave for Sunfu to meet the new governor and Shou Guini. They were also puzzled by the slowness of Sunfu City's response.

According to the retainers of the Asahina family who stayed in Sunfu, in the immediate aftermath of Imagawa Yoshimoto's death, Shou Guini had been busy stabilizing the situation and establishing an heir, so she did not pay much attention to the turmoil in Mikawa - perhaps she also felt that the Okabe family and the Asahina family could not fight.

After the news of the outbreak of civil war between the two families, according to the retainers left behind, Shougui Ni seems to have sent a lot of ninjas to immediately start investigating the so-called "who is the mole". According to Sena's analysis, it is very likely that Shou Guini wants to find out the reason before announcing the mediation and punishment results - after all, the direct troops of the main family have not returned to Junfu at that time, and she is afraid that she will not be able to control the field. However, this series of intensive investigation activities came to an abrupt end after the arrival of the main family's troops.

Originally, after the return of the directly governed forces to Junfu, Shou Guini should have immediately ordered the infighting to stop. Even if you can't find a traitor, you should immediately ask the governors of each family to stop using force and come to Junfu City to confront you. However, Shou Guini was unusual, refusing to express his stance on the dispute on the front line, and only said a few words of "exercise restraint", and then there was no more news.

Sena secretly speculated that Shou Guini probably felt that since the situation between Mikawa and Owari was irreparable, he simply did not try to remedy it. Her old man may feel that the Imagawa clan is not prestigious, and it is difficult to suppress the powerful Hao clan under him, so she deliberately allows the retainers of the Hao clan to fight among themselves and weaken their strength, so as to strengthen the power in the hands of the family governor in one fell swoop.

Both Yu Qiuping and Asahinai Tai Chao agreed with this inference - this is a measure that only people with great courage and skill dare to take - Shou Gui Ni does have this strength. It was clear that the assault on Macheng would require a lot of casualties, and the Asahinai Tay Dynasty was not willing to do so. Even if he was loyal to the Imagawa family, he did not want the Asahina family to decline in status because of their severe weakening. Therefore, he and Sena Toshi plan to return to Sunpu Castle together to resume their lives, provide a large amount of evidence to prove that the Okabe family is a traitor, and let Shou Guini make a decision to end this civil war.

After the departure of the two supreme commanders, the burden of commanding the whole army fell on Yu Qiuping's head. Skilled in defense, he was nervous about commanding such a large army for the first time, but he could still handle it if he asked himself. He changed the order of the troops, asked the troops to strengthen the defense line over and over again, built dense fortifications around the four gates of Yinma City, and also set up a perfect response system.

The four gates of the city are each in charge of the four families. The most likely breakthrough defense line of the Okabe family, the east gate, was defended by a large battalion under Jobanbei, and at the same time, the Okuhei family and the Nakane family were also in this direction. And the north gate of Inma Castle is in charge of the Asahina family. And the Ii family, the Iio family, who took refuge in it, was also monitored by the Asahina family because of their strong strength, and stayed at the north gate. The west gate and the south gate, which were less stressed, were handed over to the Sena family with the Miura family, and the Sekiguchi family with the Katsuyama family.

Akihei first dug a trench around the entire castle town of Inmajo, and then placed a row of wooden fences behind it. On this circle, every fifty meters, there will be a tall watchtower on which several archers monitor the movement of the city. And on the periphery of this circle were four large camps set up against the gate. The camp is all on the official road, and there are a large number of fortifications in front, such as trenches, horse rejections, fences, traps, shooting towers, and earthen walls.

Once the Okabe family tries to break through, the archers on the lookout can spot and delay it at the first time. The troops responsible for defending the city would then use the time gained by the trenches and fences to quickly move into their own fortifications, while troops from other directions would rush to support or attack the city directly. Yu Qiuping's move was mainly anti-guest, and he directly took the advantage of defense in his own hands, making the Okabe family passive.

The Okabe family also tried to organize two breakouts on the 11th and 12th, but they were both thwarted by Akihei. For the first time, the Okabe family attacked the east and west, pretending to attack the east gate in a big way, but in fact rushed to the west. This move did confuse the Asahina family, as the latter also felt that the East Gate was the real main attack. When the Okabe family opened the east gate and sent out troops, the troops from the north gate and the south gate immediately began to move towards the east gate to support. Therefore, when the Okabe family went out of the West Gate in a big way, the Sena family did encounter the crisis of being outnumbered. And the Miura family was an ally of the Okabe family not long ago, although they didn't dare to act rashly because the hostages were in the hands of the Asahina family, but it was true that they didn't have much combat effectiveness. As a result, the Sena family fell into a bitter battle, and the camp located outside the west gate was besieged by the Okabe family.

Simply Yu Qiuping reacted quickly, and Chang Panbei immediately crossed the somewhat chaotic South Gate troops, and rushed directly to the West Gate through the castle town to support. The troops used by the Okabe family to protect the flanks were quickly defeated in front of Tokiwabei's gun array, and the Okabe family had to suspend the offensive to deal with Tokiwabi. At this time, the troops of the north gate and the south gate also carried the hammer to storm the city, and there was a panic in the city. In desperation, Motonobu Okabe had to retreat to the castle, and the first offensive was declared a failure.

And Yu Qiuping also learned from this chaos - you can't support indiscriminately. The Okabe family is sitting in Inimajo, and they can take advantage of the condescending view from the castle tower and the advantages of internal maneuvering, and freely mobilize the troops of the Asahina family on the battlefield to find weak points in the encirclement. The Asahina family, which is on the periphery, is much more clumsy due to the lack of vision. If you support blindly, it is very likely that the Okabe family, who has a clear vision, will seize the weakness and break through.

Therefore, Yu Qiuping issued an order - all units should not leave the position without authorization to maneuver, no matter what happens, until they have received an order from Yu Qiuping to support.

In the second breakout, the Okabe family did not try to use a strategy again, but directly attacked the defense line outside the east gate - if the breakthrough was successful, they could retreat east to Okabe Castle. And Yu Qiuping did not show weakness, and Chang Panbei used the fortifications to stubbornly resist the attack of the Okabe family, but he could not make the Okabe family make progress for an hour. After it was determined that the entire army of the Okabe family would be dispatched, Yu Qiuping also ordered the troops outside the other gates to rush to support, and in one fell swoop defeated the Okabe family, who tried to break through, and Okabe Motoshin retreated to the castle of Yinma, and was no longer able to attack.

After two failed attacks, the number of troops available to the Okabe family in the castle was also greatly reduced, with nearly 300 casualties, and morale was further depressed. Outside the castle, the Asahina clan also suffered more than 200 casualties in two battles, but due to the large number of people, they were more able to endure casualties, and their morale was getting higher and higher.

On June 12, Asahina Tai and Sena Toshiya arrived at Sunfu Castle and asked to meet Shou Guini. The two of them went to Sunfu Castle alone, and they themselves showed their loyalty to the Imagawa family. The actions of the two have won the approval of many elders and relatives of the Imagawa family, and the trend of public opinion has become more and more unfavorable to the Okabe family, and for a time there is a tendency for the wall to fall down and everyone pushes it. Originally, the No. 1 wealthy family in the Imagawa family is in turmoil at the moment.
