On December 20, early in the morning of the day after the arrival of the Yuqiu family, in the castle tower of Okazaki Castle, the important ministers of the Yuqiu-Tokugawa family gathered for an evaluation meeting. At the meeting, Yu Qiuping announced his amazing plan to the people.

"According to His Royal Highness Tokugawa's plan, our trip will advance along the north road all the way to the north gate of Hamamatsu Castle and set up camp, echoing Hamamatsu Castle from afar, and flanking the Takeda army on both sides." Yu Qiuping hung the map on the wall and pointed out the key positions with a handful, "But given that the opponent is Takeda Shingen, he will definitely not sit back and watch us complete the strategic plan." He must have heard of his strength in military strategy, he has rarely been defeated for decades, and the Koshu Corps under his command is one of the strongest in the world, and it is not too much to say that he is the first military master of the Warring States. We must take into account the fact that Takeda Shingen left part of his army to prevent His Highness Tokugawa from going out of the castle to flank us, and personally led the main force to meet us. ”

"The Takeda family has a very strong cavalry, including the Chibei cavalry, and the total number of cavalry is about 3,000 people." According to the information collected by Sanada Masayuki not long ago, Yu Qiuping reported to everyone present, "And the number of cavalry in our two armies combined is only 500. Our cavalry was completely unable to compete with the Takeda family, and it was naturally difficult to cover the retreat of the troops. If the cavalry of the Takeda clan sticks to us on the plains near Hamamatsu Castle, we will not be able to retreat to Yoshida Castle before the main force of the Takeda Army catches up with us. With the exception of Yoshida Castle and Hamamatsu Castle, there is no fortified castle suitable for our defense on the Mikawa-Toe line. If this is the case, we may be forced to accept a field battle with the main force of the Takeda family in the plains and wilderness, which we do not want to see, but which Takeda Shingen wants to see. "Takenaka Shigeharu was not there, and Yu Qiuping had to take on the role of Takenaka Shigeharu himself and analyze the situation for everyone, "Because if we let our 12,000 army with 1,350 iron cannons enter the city, the Takeda army will no longer be able to take us, after all, the cavalry can't climb the city wall, so Takeda Shingen is bound to pursue to destroy us in the plain field battle." Because in the plains and wilderness, the Takeda family's cavalry mobility and strength superiority can be maximized, and we have almost no chance of winning. ”

"What my uncle said is very true." Tokugawa Nobuyasu had been persuaded by Yu Qiuping's analysis last night, and when he listened to it again today, he was even more convinced.

"Therefore, we must adopt a countermeasure plan, and we must not give Takeda Shingen a chance to force us to fight a decisive battle in the plains and wilderness." Yu Qiuping knocked on the map heavily with the picking, and said in a deep voice: "And my plan is to enter the mountain!" ”

·

"As I said earlier, if the Takeda Army wants to raid us and force us to fight on the plains, they will definitely lure us as close to them as possible and as far away from Yoshida Castle as possible." Yu Qiuhei traced all the way along the march of the northern line with a collection of accessories, and at the same time analyzed, "If we had just advanced to three days away from Yoshida Castle, the Takeda Army under Hamamatsu Castle would have sent troops to us. Then as soon as our ninjas and tanma are discovered, we can immediately withdraw our troops. The Takeda Army was still about 50 miles away from us at this time, and even if we were stuck by the cavalry of the Takeda family, we could retreat to Yoshida Castle before the main force of the Takeda Army caught up with us, leaving the Takeda Army to return in vain. ”

"Therefore, the Takeda Army must put its prey, that is, us, closer before making a move. For example, 20 miles further into the valley, or 15 miles further before the valley of the three square fields. According to the staff's estimation of the speed of the march of the two armies, once we reach Iiya or beyond, there will be no way to return to Yoshida Castle before the main force of the Takeda Army catches up with us. ”

Regarding the calculation results of their own staff, the senior warriors of the Yuqiu Army never had the slightest doubt. However, the people of the Tokugawa family didn't understand, and frequently set their eyes on Tokugawa Nobuyasu and Gao Li Kiyocho, but they were all rejected by the two with very positive eyes.

"And according to the further calculations of the General Staff, if we had learned that the Takeda Army was coming to attack us in Mikatahara, we would have to fight with the Takeda family in the field on the plains. Therefore, we must not advance to the triparta. At most, the most, move on—" Yu Qiuping said as he knocked the position of Jing Yigu with the mining match, "Jing Yigu." ”

"Because in Iiya, if we find the Takeda Army coming towards us from 30 miles away, we will have time to retreat for three days before the Takeda Army catches up with us, and then head north into the Ina Mountains." Yu Qiuping pointed to the location of the third day, "Although there is no mark on this map, I used to be familiar with this place. From the third day, there is a mountain road that leads to the Ina Mountains. Although the mountain road was not narrow enough, it was enough for our troops to hold back the Takeda army and not be outflanked by the cavalry. Fight and retreat, all the way back to—"

"Wait a minute, Your Highness!" Before Yu Qiuping's words fell, the captain of Hosoyanagi Bei, Mizenzaki Nakahide, suddenly raised his hand and interrupted, "But this mountain road is not wide, and our 12,000 people don't have time to retreat together!" When the Takeda family is killed, a large number of us are crowded at the intersection of the mountain that can't be squeezed in, won't it be over! ”

"You're right, so our auxiliaries, with a large number of baggage, stop at the end of the march and let the soldiers advance with the necessary dry rations, water, and armor. Three days after their arrival, the auxiliary corps began to carry the baggage into the mountain road, and they themselves entered the mountain road first. If the Takeda Army attacked us, the soldiers immediately retreated. By the time the soldiers retreat to the valley mouth, the auxiliaries should have all withdrawn into the mountain road, and the soldiers should withdraw in turn. If the Takeda Army did not attack immediately, the 4,000-strong auxiliary army was left to set up camp at the intersection of the mountain road as a granary to deliver grain and grass to the Iyi Valley on the front line. The rest of the auxiliaries camped down the mountain road to rest. ”

"Got to know Your Highness. I didn't expect Lord Takenaka to be here, and His Highness also has such skills. Even in the face of the great enemy, Mimasaki Nakahide still looks like a hanger, and he didn't forget to joke, "It's amazing." ”

"How is it possible, it was obviously made by Yu Nan, I heard it when I went to report yesterday." Xueshan Shishishi, who was sitting on the side, took over the conversation with a smile, "Let His Highness do it, I won't be able to finish it in a few days." ”

"There are still outsiders, can I save some face for your Highness!" Yu Qiuping heard that there was already a faint laughter on the side of his own samurai, and the Tokugawa family couldn't help but laugh a little - the Tokugawa family's meetings have always been very serious, and if anyone dares to interrupt arbitrarily, they will be locked up, let alone laugh at the lord.

"Faithful, you stinky boy, still laughing!" Yu Qiuping saw that Xueshan Faithfulness was still laughing on the side, and his nervous mood couldn't help but ease a little, "You also told me before you set out on the expedition, if you can make a great contribution, let me help Hu Song Yuanfu!" What's the matter, do you still want to? ”

"Ah, don't, don't, Your Highness!" Akayama Nominee panicked when he heard this, and immediately sat down in a very well-behaved sitting position.

"Hmph." Seeing this, Yu Qiuping chuckled, clapped his hands, and continued: "Then let's continue." ”

"If the Takeda family doesn't fight, we will echo His Royal Highness Tokugawa from afar, and drag it until spring ploughing. If the Takeda family were to call us, we would retreat all the way to the third day, and then head north from the third day into the Ina Mountains. ”

"What about entering the Ina Mountains?" Mimasaki Nakahide asked again, "The Takeda Army is not stupid, how can they fight us in such a narrow terrain?" He must be looking for a suitable place for cavalry charges! Otherwise, the cavalry on the mountain road will not be the target of our iron gunners. ”

"Yes, Takeda Shingen will never go to war with us in the mountains, so I plan to sell a flaw, that is, to introduce Takeda Shingen into a battlefield that he can accept." Yu Qiuping nodded, and then used the collection to point out the location of Shirakuyuan in the territory of Sanhe on the map, "That's Shirakuyuan." From the road we enter the mountain all the way north, the mountain road gradually becomes wider, like a trumpet. After walking out of the mountain road, we will arrive at Shirakuhara, a small plain crisscrossed by many streams and rivers, with a depression in the middle. We will set up positions in the depressions. ”

"Set up a position in the depression?" Hearing this, Fukushima Yasunari felt that something was wrong, and he also opened his mouth to put forward his opinion, "The Takeda family's cavalry is famous all over the world, if they are allowed to charge towards the depression condescendingly, won't we be more than lucky?" ”

"If it's not arranged, that's true. That's why I arranged for the young lord of Tokugawa to lead 3,000 men to Shirakuhara in advance to set up the battlefield. Yu Qiuping smiled slightly, and began to describe Oda Nobunaga's arrangement in the battle of Nagashino, a great war that attracted worldwide attention and changed the direction of Japanese history.

Although it is located in a depression, the depression is surrounded by a dense network of water. Oda Nobunaga laid a large number of horse fences, horse repellents, moats, and earthen walls along the Toyogawa and Renzi rivers, and hid the iron gunners behind the complex fortifications. When the Takeda Army began to charge, it was difficult to break through this complex defensive line, but it was fired at by the 3,000 iron gunners of the Oda family, and suffered heavy losses.

However, even in the case of many times inferior troops, poor terrain, and improper tactics, the tenacious Takeda Army still stubbornly fought with the Oride coalition army until the last moment, breaking through multiple horse fences and continuously breaking through many forces of the Oda family. If it weren't for the fact that the leader of the Takeda family's red reserve army, Yamachi Masakai, was accidentally killed by Honda Tadakatsu in the battle, the Takeda army would not have suddenly collapsed. It can be seen from this that the combat effectiveness of the Takeda Army is fierce.

Yu Qiuping planned to "repeat the old trick" this time, pirated Oda Nobunaga's idea of fighting in Nagashino in his previous life, and also gave Takeda Shingen a Nagashino battle. However, the Takeda family's troops in this battle were more than those of the previous Nagashino, but the Oda family's troops were less than those in the previous life, and the commander of the Takeda Army was also Takeda Shingen, the first warman of the Warring States period, who was several times stronger than Takeda Katsuyori; Even though the quality of the Yuqiu army was much higher than that of the Zhide coalition army in the previous life, Yuqiuping still did not have the confidence to win. He just wanted to use this to fight with the Takeda family and force the Takeda family to give up their plan to annihilate themselves in the field.

"If that's the case... It's doable. After listening to Yu Qiuping's arrangement, Fukushima Yasunari changed his previous thoughts, "It's just that Your Highness, what if the Takeda family didn't pursue us when we retreated into the valley and went straight to Yoshida Castle, or if we turned around and left after we lined up in Shirakuhara and didn't fight us?" We lacked cavalry, and we did not have the means to force the Takeda family to fight a decisive battle with us. ”
