Because in the process of Matsunaga's army marching in the alley, it was not only the front of resistance that was encountered, but also attacked from all sides. Whether it was arrows, projectiles, javelins, or even stones, Matsunaga's army was attacked from all directions in a continuous manner. Originally, the Matsunaga army had an overwhelming advantage over the defending Oda army in terms of numbers - because the Oda family's Mitsunari army's troops had to guard against the Miyoshi family at the West Gate. However, the Matsunaga family was unable to do so due to the endless long-range harassment from the flanks and diagonal rear.

"What the hell is going on?" Matsunaga finally sensed that something was wrong, and looked around vigilantly, only to realize that the situation was wrong. The troops of the Oda family did not all resist the front of the Matsunaga family, but scattered many people, scattered one by one to various commanding heights in the castle, and were firing at the army of the Matsunaga family without stopping. Gunners, archers, gunners, and even a lot of stone-throwing auxiliaries.

"Trouble is dead." Matsunaga muttered unpleasantly, looked at the main force of the Oda family in front of him, and said angrily: "Why don't you want to fight to the death one-on-one!" ”

"By the way, knock down that three-story roofoki together!" Matsunaga took a fancy to the three-story building with the most iron cannons and bows and arrows. Under his command, the Matsunaga family sent a special team and began to approach the three-story building. However, he was blocked on the road by a company of Tokiwanbei. In the narrow streets, the spears almost blocked the road, and there was no chance to flank it. The Einsatzgruppen had no choice but to come back and report.

"Nearly 300 soldiers?" Matsunaga frowned, "It seems that for the enemy, this yashiki is very important." ”

"Give you another 2,000 people, copy all the bread, and take down the neighborhoods around that house." With a wave of Matsunaga's hand, a large number of troops from the Matsunaga family began to rush towards Yashiki. However, they immediately faced the same predicament as when the main forces attacked. The constant company in front of them fought and retreated, and they were once again attacked from the flanks and rear, the same four as before: projectiles, arrows, javelins and stones thrown by the auxiliaries.

"This method of arranging the formation was brought back by Kang Qing from Europa." Yu Qiuping stood on the castle tower and watched with satisfaction as the street battle developed in the direction he expected: "It's called the fortress. ”

"Momiji, what the hell does this mean?" Confused, Ikeda Hengxing grabbed the railing and craned his neck to look into the city: "What kind of trick did you change to beat Matsunaga Army so hard?" ”

"In fact, this is not a fortress in the strict sense, it can only be said to be a reproduction of a concept." Yu Qiuping smiled slightly, turned around, took out the ribs of Sena Shijun from his arms, and gestured on the floor. Ikeda Hengxing, Takenaka Shigeji, and Sanada Masayuki, who were standing on the side, all gathered around with great curiosity. Yu Qiuping was on the floor, and roughly carved a square with ribs, and then drew a five-pointed star.

"In short, it is to change the traditional defensive formation from a convex polygon to a concave polygon." Yu Qiuping pointed to the square on the map and said, "Traditional cities are built in square places. When the generals set up improvised defensive positions or defended in street battles, they also adjusted their defensive lines into a convex polygon. ”

"But when the enemy attacks the convex polygon, he will only face an attack from one direction." Yu Qiuping chose a point from outside the square, made a perpendicular line on the edge of the square, and then dotted the edge.

"But if it's a bastion — that's a concave polygon defense." Yu Qiuping twisted slightly, and gestured at the pentagram again. "No matter which side you attack, the side or back will be exposed to the attack, and there will be nowhere to hide. For example, if you attack this corner," Yu Qiuping said, pointing to the side of one of the corners of the five-pointed star, and then pointed to a corner adjacent to that corner, "The troops on this corner over there can shoot directly at the back of the besiegers and inflict great damage on them." ”

"Your Highness." Seeing this, Shigeji Takenaka was slightly puzzled, took out the rib difference in his arms, and nodded on the tip of the five-pointed star, "If the other party only stares at this protrusion and attacks, won't it be difficult for the people on the other two sides to form support." ”

"No, no, no, it's not like that." Hearing this, Yu Qiuping shook his head again and again, "If you only stare at the sharpest part of the protrusion, you won't be able to deploy the troops yourself." Whenever you want to extend the range of your attack, you have to spread your troops along that corner, and you'll be exposed to the defenders on the other two sides. ”

"And this protrusion is solid." Yu Qiuping pointed to the five corners of the five-pointed star in turn as he spoke, "Even if it is knocked down, it will not hurt, only the center inside the fortress is hollow." ”

"However, Kang Qing said that the defenders of the fortress basically use iron cannons, and the bows and arrows are a little weak." Yu Qiuping looked at the battle situation of His Excellency the Castle Tower with some concern, "I don't know if this experiment will be successful." ”

·

It has to be said that the application of the concept of the fortress this time was very successful. Matsunaga is obviously not very accustomed to this method of warfare, and he tries everywhere but runs into walls everywhere, and he is very annoyed by being harassed. Worried that it would be difficult to maintain firepower by clinging to the few iron cannons and bows and arrows, Yuqiu Heimoto used many spears captured from the Rokkaku family as javelins for auxiliary soldiers, and even collected a lot of stones. Later, it was discovered that in street fighting, these javelins and stones played no less role than iron cannons and bows and arrows.

At the same time, on the walls of the northern city.

"I see." Matsunaga Shu had already climbed the northern city wall in person at some point, and was looking at the situation in front of him condescendingly. Standing on a high place, he could understand the Yuqiu family's formation more clearly than Matsunaga in the melee—it was a huge five-pointed star with Ninomaru as the core. The five pointed points of the five-pointed star are the five high-rise buildings in the Kannonji Temple Castle Sannomaru, and they echo each other with Ninomaru through the cover of the troops who are fighting and retreating, and at the same time form crossfire, constantly harassing the attackers.

"It's fruitless to run around there." Although the battle-hardened Matsunaga Hide, who had never seen this kind of strange formation, quickly reacted with experience, "You can't divide the troops, and you can pull out those protrusions one by one!" ”

"At the same time, let Naito Ruan speed up the progress, first control the walls of Sannomaru, and attack condescendingly."

When Matsunaga changed his tactics, the Oda army immediately found itself in a difficult situation, and the five protruding yashiki and inns fell one after another. However, Yu Qiuping had already planned for such a situation. Whenever a bulge was about to fall, Yu Qiuping would send Ikeda Tsuneko as a reserve to set out from Ninomaru to cover, and take back the troops of Fukushima Yasunari, Charlie, Mori Kosei, Inaba Kachitetsu and others in the bulge one by one, without being outflanked and annihilated once. Seeing that the neighborhoods of Ninomaru and Sannomaru could no longer be garrisoned, the troops of the clan Buquan and Ando Shou on the city gate were also withdrawn into Ninomaru by Yu Qiuping.

"What a strong dispatching ability." Matsunaga Xiu looked at the maple bird flag in the castle tower from afar and issued instructions in an orderly manner, and suddenly understood why Miyoshi Yoshiken valued this person so much, "This kid's defense is something." ”

However, at this time, the time had been delayed until eight o'clock in the afternoon, and the Matsunaga family, who had been tired for most of the day, had to suspend the attack and start lighting a fire to cook. And the Oda Army in Ninomaru seems to have prepared lunch for a long time, and the smoke has gradually dissipated.

While it was time to eat, the samurai of the Matsunaga family also began to count the number of casualties. After a morning of fierce fighting, more than 600 of Matsunaga's 18,000-strong army had been killed and nearly 1,500 wounded. And Matsunaga Shu himself estimated that the casualties of the Oda Army were estimated to be more than 500 people, and it would not reach 800. This kind of exchange ratio is really unacceptable to him - if he really wants to kill all the Oda troops in the city, then his troops are estimated to have heavy casualties.

Thinking of this, he couldn't help but set his eyes on the Xicheng Tower, where the Miyoshi Army was stationed who had been releasing water all morning. The Matsunaga family's total territory of more than 600,000 stones is only more than 20,000 people. If the main force fights here until it is exhausted, Miyoshi Yoshiken will definitely not let go of this great opportunity to seize the land of Minami Omi.

As a result, in the second round of attacks after lunch, Matsunaga Shu had already kept an eye on it, and instead of besieging from all sides, he only stared at one of the gates of Ninomaru to attack, trying to minimize casualties. However, this is also destined not to be fast. The siege turned into a long tug-of-war, and it wasn't until sunset that the Matsunaga family barely made it to the top of Ninomaru's castle - but the sight was enough to make them despair.

Akihei took almost the same measures as Sannomaru - they used the main pill as the core, and five or six towering buildings as protrusions, once again constructing Akihei's "fortress-style" defense system. And the troops on Ninomaru also cautiously retreated to this new defensive system and the walls on both sides.

"It's endless." Matsunaga Hideshi himself climbed the castle wall and sighed at the Oda family's fortifications. Yu Qiuping was very decisive every time he retreated, as long as a fortification could not bring a good exchange ratio, he would give up decisively, so that the Matsunaga family has never had a good chance. Seeing that it was getting dark, it seemed that he would not be able to take the Honmaru tonight, so Matsunaga Shu had no choice but to order the troops to retreat from Ninomaru - otherwise the lonely section of the city wall would definitely suffer a counterattack and lose troops in vain. The morale of the Matsunaga army suddenly languished as the section of the city wall that had been captured after an afternoon of struggle was taken back by the Oda army.

"The Oda family's reinforcements may arrive tomorrow evening..."Matsunaga Shu thought silently, "Tomorrow morning, if you can't beat it, you will have to retreat." ”

Thinking about this, the more Matsunaga Xiu thought about it, the more angry he became, and the always peaceful expression on his face was a little unbearable. originally thought that the surprise attack battle was nine out of ten, but it was dragged on by Yu Qiuping for so long.
