After the end of spring plowing in the second year of Motokame (1571), the Oda family army made a comeback. This time, they targeted the Asai family in Kita-Omi. The Oda family's remaining troops in Minami Omi and Oda Nobunaga's main army flanked left and right, and soon surrounded Yokoyama Castle and Sawa Yama Castle, which were strategically important points in Kita-Omi. Oda Nobunaga went further north, stationed troops on Mt. Gomae, threatening the safety of Kotani Castle. After estimating the comparison of the strength of the enemy and us, Asai Nagamasa did not rush to send troops, but waited for reinforcements from the Asakura family to arrive. Ashikaga Yoshiteru tried to echo the actions of the Asai family and the Asakura family, but due to the pressure of the military forces of Akihei Yuakihei, Kinoshita Hideyoshi, and Akechi Mitsuhide, he did not dare to act rashly for the time being. However, his small movements did not stop, but secretly instigated the monks and soldiers of Enryakuji Temple in Mt. Hiei to make trouble and attack the baggage team of the Oda Army in the Kyoto area.

However, the Asakura family's reinforcements this time were much slower, and by the time Asakura Keiheng's reinforcements arrived, Yokoyama Castle had already fallen, and Isono Yuanmasa of Sawa Yamajo was almost exhausted. There are two strategically important places in Kita-Omi, one is Otani Castle, and the other is Sawa Mountain Castle, and Isono Yuanmasa is also the second most important minister in the Asai family after the three generals of Hai Chiyu, and he is one of the best fierce generals, and Asai Nagamasa can't abandon him if he is reasonable. So, after the Asai family and the Asakura family converged, the two armies went south together in an attempt to relieve the siege of Sawa Yamashiro.

However, the Oda army had already set up a position in the sickle. Although they had an advantage in terms of troops, the last time they were defeated by the Eagle Preparation, the embarrassment of being defeated by the Eagle was still a shadow in the hearts of the important ministers of the Oda family, so they took a defensive position very safely.

Originally, the number was not superior, but the Asai-Asakura coalition had to take the initiative to attack in order to rescue Sawa Yamashiro. Originally, Asai Nagamasa thought that with the combat power of the Eagle Preparation, even a death battle would be enough to break through the position of the Oda Army. However, what he never expected was that Oda Nobunaga, who had deep pockets, actually raised and purchased 2,000 iron cannons and waited for the eagle.

After the Eagle Bei discharged a dense formation to attack the position of the Oda Army, 2,000 iron cannons opened fire in unison, bringing huge losses to the Eagle Bei, which was tightly organized and densely formed. Originally, the crosshairs and hit rate of the iron cannon were not very high, but the neat formation of the eagle just allowed the iron cannon to double its power. As long as the projectile is fired in the right direction, the probability of hitting the person will be greatly increased. The neatly prepared procession of eagles was knocked to the ground by iron cannons like wheat harvesting, and rows of ashigaru were shot and killed.

Even though Taka Bei endured heavy casualties and rushed into Oda Nobunaga's position, he was eventually repelled by the Oda army due to insufficient numbers. More than half of the 1,000-strong Eagle Bei was lost in this battle, and his vitality was greatly damaged, and the Asai-Asakura coalition was forced to retreat.

However, in the early morning of the next day, the Oda Army, which had refused to attack despite the challenge of the Asai-Asakura coalition, suddenly launched a surprise attack, and under the hard work of Shibata Katsuie and Takigawa Kazuyoshi, the Asakura Army abandoned the Asai Army and withdrew due to the confusion and collapse of the organization. Asai Nagamasa was unable to support himself and had to retreat to Kotani Castle to hold on. With the retreat of reinforcements, Sawa Yamashiri, which had been besieged for a long time, also lost the motivation to hold on, and Isono surrendered to Oda Nobunaga half a month later.

Oda Nobunaga then transferred Hideyoshi Hashiba from Kyoto and transferred to him the strategic places where the Asai family was monitored, such as Sawa Mountain Castle, Yokoyama Castle, and Toragomae Mountain, and he was responsible for keeping an eye on the Asai family.

The great victory of the Oda army in the battle of the scythe shook the Oda family, and the once invincible Asai family Takabei suffered for the first time. However, the retainers of the Yuqiu family were not happy when they heard this. Oda Nobunaga creatively came up with a way to break through the assault of the Eagle Preparation: a salvo of iron cannons. And this is bound to be imitated by other hostile daimyo and used to assault the queue of the Yuqiu army, which is exactly the same as the eagle.

After resolving the worries of the Asai family and the Asakura family, Oda Nobunaga did not disband his troops, but turned south in June of the second year of Motogame (1571) and launched a war against Nagashima. The menacing Oda army was bound to win this time, and the 40,000-strong army was divided into three ways to kill Nagashima. Oda Nobunaga himself set out from Tsushima, and the Einsatzgruppen with Niwa Nagahide as the general attacked from Nakasujiguchi, while another Einsatzgruppen with Shibata Katsuie as the general attacked from Otaguchi.

However, Honganji is not a fuel-efficient lamp either. After Oda Nobunaga defeated the Asai-Asakura coalition without disbanding the troops, Honganji Xianru had already sensed the danger and sent Honganji's strongest mercenaries, Saga and Nerai, to Nagashima to help in the war. Both the Saga and Nerai were known for their use of iron cannons and were masters of guerrilla warfare. They waged a guerrilla war against Oda Nobunaga in the complex terrain of Nagashima's water network, harassing Oda Nobunaga to the ground. The Oda Iron Artillery Team, which had just returned from victory, was no match for the Saga and Nerai in the complex terrain, and was beaten to the ground.

As soon as Honganji Temple shouted, a massive attack broke out in Owari and Ise again, attacking the grain routes of the Oda army on a large scale. Minami Omi also broke out again, cooperating with the remnants of the Rokkaku clan and the monks of Mt. Hiei to disrupt the situation in. A fire broke out in the backyard of Oda's house, and it seemed that it would not be able to drag on.

Shibata Katsuya, who was provoked by this kraft candy style of warfare, knew that the Oda family could not drag on, so he relied on the sharpness of the Asakura family that he had just broken with the sickle, and no longer entangled with the Saga people and the Nerai people, but led the army commander to drive straight into Nagashima Castle, intending to force the Saga people and the Nerai people to have a dignified battle with him. However, on the way up the mountain, he was shot in the lower abdomen by snipers ambushed by the Saga people, and was seriously injured and nearly died. The army on the side of Ota Kou was instantly disorganized and hurriedly withdrew from Nagashima Castle. The monks and soldiers in Nagashima Castle immediately launched a pursuit, and cooperated with the Saga and Nerai to besiege the Oda army. At the critical moment, one of the three members of Minong, the clan Buquan stood up and led the army to counterattack alone, blocking the pursuit of the Long Island side, but he was killed in the chaotic battle.

The Einsatzgruppen was defeated, and Oda Nobunaga had no strength to fight again, so he had to lead his army back in disgrace. After learning the hard way, he decided to completely solve the civil strife in his territory before attacking outward. He first demanded that the brothers Nobuo Kitabatake and Nobutaka Kobe in Ise immediately suppress the Ichishi of Ise Province. And he himself, after suppressing the Ichijo in Owari Province, led the armies of Owari and Mino to the west again in August, aiming directly at Omi.

Minami Omi's Ichikaku has always grown stronger in the previous days, and Rokkaku Yoshiken and Rokkaku Yoshiharu father and son even recaptured Ishibe Castle and began to gather the old department in Minami Omi. This is due to the fact that Shibata Katsuie and Mori Kosei, two important ministers who were divided by Oda Nobunaga in Minami Omi, had followed Oda Nobunaga's long march to Nagashima, so the territory was empty.

Due to the occupation of Sawa Yama Castle and Yokoyama Castle, the official road connecting Ono and Minami-Omi was opened, and the movement of the Oda army between his home base and became easier and faster. Before the forces of Minami Omi Ichichi had reacted, the army of the Oda family had already arrived at Shimura Castle, the base camp of Minami Omi Ichi. Shibata Katsuie, who had previously been deeply humiliated by the defeat at the foot of Nagashima Castle, went out with an injury, and took the lead in bandage, carrying a ram to storm the city gate. Encouraged by him, Oda's army gained momentum and captured Shimura Castle in just one day, killing countless people.

Shimura Castle fell, and Minami Omi was defeated and defeated. Originally, they were still harassing and resisting in various places, and they had always gone into hiding and fled back to the countryside to avoid being pursued by the daimyo. Generally speaking, the main components of the Ichistoku are the local people, and the leaders are the monks and monks of Honganji. After the Daimyo suppressed the Honganji forces that had been suppressed, the most they could do was to punish the Honganji forces that led them, and they would not be held accountable for the people, after all, they still had to pay taxes on their farming. However, Oda Nobunaga was unusually tough this time, and actually sent troops to find the people who had fled back to the countryside. However, although Oda Nobunaga was tough, the samurai under his command did not dare to make a mistake, and just grabbed dozens or hundreds of people and came back to deal with them.

However, Oda Nobunaga, who saw his subordinates dealing with him like this, was furious, and scolded all the retainers who failed to capture them effectively. Oda Nobunaga, who was furious, poured all his anger on Ishibe Castle, and the Rokkaku family didn't even hold it for half a day, so they fled to the Koga Mountains again.

Oda Nobunaga, on the other hand, seems to have been angry after quelling the Minami-Omi rebellion, and actually led his army straight to Mt. Hiei. Frightened by this, Mt. Hiei Enryakuji hurriedly withdrew all the monks and soldiers sent to harass the Oda family's troops, and sent an envoy to apologize to Oda Nobunaga, hoping to settle the conflict. However, Oda Nobunaga has been in a lot of trouble for the past two years, and he has long been extremely unhappy with the monk - Hieiyama Enryakuji Temple actually sent people to harass the Oda family before, which added fuel to the fire. As a result, Oda Nobunaga categorically rejected Enryakuji's request for peace, led his army to surround Mt. Hiei, and gave way to Sakuma Nobumori and Akihei Yuakihei, who were on the front lines of Settsu and Kawachi, to lead their troops into the war and participate in the encirclement and suppression of Enryakuji Temple.

Mt. Hiei Enryakuji Temple has always been a forbidden place for Buddhism, and it is a holy place in the eyes of countless believers all over the world, and its status in Japan is as important as that of Mecca. Seeing that such a temple was about to suffer a military disaster, Ashikaga Yoshiteru immediately couldn't sit still, and rushed to mediate at the request of Enryakuji Temple, but was rejected by the angry Oda Nobunaga. And the emperor saw that something was wrong, so he actually sent three waves of ministers in a row to persuade Oda Nobunaga, but Oda Nobunaga didn't even give the emperor face this time. At the assessment meeting on the evening of 11 September, he directly gave the order to capture Mt. Hiei, and immediately caused the camp to explode.
