Shimazu Tadashi disagreed with Kuroda's words: "Don't look at you and I only have more than 12,000 people, but my Shimazu warriors can completely defeat five with one. Now that the remnants of Otomo have made a comeback, I am determined to let him understand the combat power of my Shimazu family, so that these guys who don't know whether they are alive or dead will know who the real overlord of Kyushu is. ”

Shimazu Tadashi does have the strength to say such a thing, in the Battle of Ogawa in the sixth year of Tensho and the Battle of Okita in the twelfth year of Tensho, the Shimazu army won more with less, defeating the "Bear of Hizen" Ryuzoji Takanobu and the "Rokushu Taishou" Otomo Sorin, and in less than ten years, the "Three Heroes Competing for Hegemony" on Kyushu Island evolved into a "dominant family" before Hideyoshi's conquest, and became the force closest to the ambition of "Kyushu unification" in Kyushu.

Although Kuroda Rusui believed that the Shimazu army was strong, but in the face of the Toyotomi coalition army, which had 5,000 more people than his own side and was supported by the Tachibana rapid-fire team, he still beat a drum in his heart, to be precise, at this moment he felt that it was time to plan a way out for his defeat, so he summoned his retainers to discuss in the battle many times, but in the end he could not come up with a satisfactory plan, which made him sigh "Today may be the last battle of my life."

At this time, the main formation of the Toyotomi army was a different scene, with the addition of Tachibana Muneshige's 4,000 army, the lifeless atmosphere of the previous day was suddenly relaxed, Kato Kiyomasa and Konishi Yukijing excitedly discussed with Soshige whether to first defeat the flank in charge of the Kuroda army or directly attack the main force of the Shimazu army; Otomo Yoshito was originally the lord of Somo, and it was not until after the Kyushu expedition that Somo became an independent daimyo, but Somo has always been benevolent and righteous, and when he heard that the Otomo clan was revived in the Kunisto Peninsula, he boldly allowed his Otomo relict to return to Otomo Yoshito, and at the same time sent money and food to solve his urgent needs. For a while, the formation was very lively, and there was no atmosphere of slaughter before the war.

At noon, Tachibana Muneshige, who was only 30 years old, sat on a horse in high spirits, dressed in the ancestral Iyo Satsu Sewing Ensu Leather Wrapped Buddha Pill Carcass. As the vanguard of this battle, as soon as the horn of the conch behind him sounded, he immediately led the samurai of the Tachibana family into the battlefield, kicking off the battle of the day.

Not to be outdone, Shimazu Tadashi ordered the retainer Ijichi Shigeshun to lead his army to meet the battle. In his mind, this battle became, to a certain extent, a decisive battle between the forces of southern Kyushu, represented by the Shimazu family, and northern Kyushu, represented by the Otomo and Tachibana families. The Otomo family wanted to avenge the almost annihilation of the year, and the Shimazu family was angry about Otomo's assistance to Hideyoshi in launching the Kyushu expedition.

When the two armies entered the middle of the battlefield to engage in a fierce battle, a surprise attack team of about 4,000 people, consisting of the Tachibana Iron Artillery Team, the Kato Cavalry Team, and the Otomo Ashigaru Army, circled the flank of the Shimazu and Kuroda coalition forces to launch a sneak attack.

Just when the main force of the Shimazu army was at a loss because of the battle with the Tachibana army, the iron artillery team in the surprise attack team took the lead in firing, disrupting the formation of the Kuroda army in one fell swoop, and the cavalry team immediately launched a charge when they saw this, and the ashigaru team followed closely and entered the formation.

Seeing this, Kuroda Rusui immediately ordered Kuriyama Riyasu, one of the "Kuroda Eight Tigers" and "Kuroda Twenty-Four Horsemen", to lead the horses to stabilize the defensive line. But the formation was scattered, the army was in turmoil, Kuriyama Riyasu not only failed to resist the attack of the surprise attack team, but was shot and killed by Takahashi Shinemon, the head of the Tachibana Iron Artillery Team, and his death accelerated the collapse of the flank, and the battle ended at 2 o'clock in the afternoon, the Kuroda army on the left flank was basically wiped out, and the surprise attack team had begun to clash with the Shimazu army, and the Kuroda army on the right flank was struggling to support under the leadership of Kuroda Issei, the son of Rusui, in order to get reinforcements from the Shimazu army as soon as possible.

In the face of the ensuing Kuroda envoys, Shimazu Tadashi was also helpless, his main force was pinned down in the middle of the battlefield by Tachibana Muneshige, and it was difficult to get out, and Kato Kiyomasa's army also joined the battle after the collapse of Kuroda's two wings, so that the Shimazu army had no time to take care of Rushui's request for help.

At four o'clock in the afternoon, Kuroda Isseri was taken by Shishiren Zhen, one of the "Four Heavenly Kings of Tachibana", and then Rusui's two younger brothers, Kuroda Toshinori and Kuroda Naoyuki, were killed in battle, and Kuroda's army was finally completely defeated. Rushui saw that the general trend had gone, and immediately led his retainers to retreat to Shimazu Tadashine's main camp, Tadaheng expressed shock and anger at its rout so quickly, but the matter has come to this point, no amount of rebuke and scolding can not change the facts on the battlefield, in desperation, he had to accept Rushui's suggestion, ordered the Shimazu army to withdraw from the battlefield, temporarily retreat to Yatsuro Castle.

At this time, the forward general of the Shimazu army, Ichi Chishishijun, had been transformed into a temple army, leading an army of 2,000 to hold Tachibana Muneshige, while the forces of Kato Kiyomasa and Otomo Yoshitomi were powerless to stop them, so they could only allow them to attack the middle end of the Shimazu army.

Kato Kiyomasa took the lead and took the lead in rushing into the middle of the Shimazu army, and won many important ministers of the Shimazu clan, such as Kamata Masajin and Irito Shigetoki, and the rest of the retainers knew that they were invincible, so they all fled to the front section to join Shimazu Tadashi, and the Shimazu army was divided into two.

Otomo Yoshitomo originally wanted to follow Kato Kiyomasa to get some benefits, but at this moment, seeing that the Shimazu army was divided, he immediately asked Kato Kiyomasa to encircle and suppress the Shimazu army behind the palace with Tachibana Muneshige, so that Kato Kiyomasa could free up his forces to chase Shimazu Tadashi and Kuroda Rusui.

At this moment, the Shimazu den army was besieged by Tachibana Muneshige and Kato Kiyomasa with less than 1,500 people, and Otomo Yoshitomi still had 3,000 people around him, so it should not be wrong for him to participate in the encirclement and suppression.

Otomo Yoshitomo originally wanted to take advantage of the fierce battle between Ichi Shigeshun and Tachibana Soshige to sneak attack from behind, but he was discovered by the lord of Osumi Kajigi Castle, Liver Fu Kanesan, and he led a line of cavalry to instantly disperse the advance of the Otomo army, and Soka Zhenxu was also cut off his left arm by Taidao because he was covering Otomo Yoshitomi. Otomo Yoshitomo was so shocked by this that he was so frightened that he led his men out of the battle and tried to join up with Tachibana Soshige.

The general general's departure from the battle caused the morale of the Otomo army to drop sharply, and the liver Fu Kanzo saw the opportunity to fight a bloody way in the Otomo army, and Ijichi Shigeshun led the main force to break through from here, and went straight to Fuji Kiyomasa. Tahara Shonobu understood what it meant for the Otomo clan to let go of the Shimazu army, and at the critical moment, he ignored Otomo Yoshitomi's withdrawal and continued to command the battle in place of Munakata Zhensu, and the Otomo army gradually restored order and morale under the leadership of this veteran, and pursued Iji Chishige with great vigour.

In order to cover the retreat of Ijichi Shigeshun and others, he led his troops to fight with Tahara Shonin on the north bank of the Kuma River, and was finally taken by Tahara Shonin because he was outnumbered. However, his sacrifice bought enough time for the retreat of the more than 900 Shimazu troops led by Ijichi Shigejun, who were constantly moving south to launch a surprise attack on the rear of Kato's army, which may have been the last chance to protect Shimazu Tadashi and retreat safely to Yatsuro Castle.
