At about forty in the afternoon, the vanguard army that received Hidebo's order launched an attack on the north bank of the Yukawa from four positions, and learned that the earthen barrel had a close range, and the front daimyo's army retreated two miles to withdraw from the range of the barrel, and then used the Hongyi cannon given by Hideho to launch an indiscriminate bombardment of the position of the Uesugi army on the opposite bank. The first and second lanes were almost completely destroyed, and the third lane was torn open by shells several gaps more than 20 meters long, basically losing the ability to resist, and most importantly, the Tsukimi Turret, located in the southeast corner of Honmaru, was also hit by two shells and caught fire, and Naoe Kaneyu, who was in charge of guarding, was seriously injured and was seriously injured, so he was treated in time to save his life, but he lost a leg and half an arm.

After this catastrophe, the morale of the Uesugi army fell to freezing point, and the defense line was on the verge of collapse, and after an hour of bombardment, Fukushima of Omotemachi took the lead in leading the army to rush to the Yukawa bank, filling the river with sandbags prepared in advance, and the daimyo of the other positions also followed suit, and for a time the south bank of Yukawa was crowded with ashigaru and migrant workers carrying sandbags, and Yukawa was not wide, and with the efforts of more than 10,000 people, it was finally paved a few paths that allowed three people to pass side by side when it was close to nine o'clock.

The actions of the Toyotomi army were all seen by the Uesugi army on the other side of the river, and the Kitagawa Hara camp generation Maeda Keiji ordered the iron artillery team to aim at the other side of the river, and as soon as the army filled the sandbags entered the firing range, he immediately opened fire, and at the same time he also ordered the Uesugi army to launch an artillery bombardment on the south bank with the remaining large barrels, and organize the Toyotomi army to approach Yukawa.

At first, many migrant workers refused to work for fear of dying at the bottom of the river, so that the roads could not be widened for a while, and many of the sandbags that had just been filled in were washed away by the river. Seeing this, Fukushima Masanori immediately ordered the Otsubo team to bombard the north bank again, this time targeting the camp of the Uesugi army, but the iron artillery team and the Otsubo team on the river bank.

Under the second round of artillery bombardment by the Toyotomi army, the Uesugi army paid a heavy price, almost all the large barrels were destroyed, and the iron artillery team of Kitakawahara also suffered a catastrophe, with nearly seventy percent of the casualties, and the famous iron artillery general Nakajo Mimori, who had a battle exploit in Hasedo, was also killed, and his 1,000 troops were assigned to the command of Maeda Keiji.

In order to prevent more people from dying under the artillery fire of the Toyotomi army, Maeda Keiji gave up the policy of rejecting the enemy from Henan, and decided to lure the enemy deeper, blurring the border between the two armies, and then letting the big barrel throw a rat trap.

Maeda Keiji's original intentions were good, but he ignored the fact that with the thousands of men and horses in his hands, he could not resist the impact of the 20,000 Toyotomi army. When the Toyotomi army stopped shelling and filled the earth again to cross the river, Maeda Keiji also immediately ordered the army to retreat behind the first line of horse guards, relying on the remaining fence combined with the fire of the Toyotomi army, which had just landed on the shore of the iron artillery team.

Most of the first to rush to the north shore were Ashigaru armed with short weapons, and these people were powerless in the face of the iron cannons, and dozens of people were killed and wounded. However, the Uesugi Army's iron artillery team had lost seventy percent of its strength before, and even if they tried, they couldn't stop more and more Toyotomi troops, who rushed to the north bank from three waterways, like black locusts, looking terrifying, and real contact was a nightmare.

Fukushima is the same name as Kato Kiyomasa in the "Seven Guns of Cheap Mountain", and now Kato Kiyomasa is guarding Kyushu, as the vanguard of the crusade army, he is even more unwilling to be taken by others, and the first to rush through Yukawa's army is the Fukushima Army, which alone laid the foundation for his future rewards.

The Fukushima Army, spearheaded, followed by cavalry and iron gunners, rushed to Kitagawara's first barrier like a tsunami. The anti-horse fence was completely destroyed, so it could not be used as a fortification to block the impact of the Fukushima army, and the 9,000 army launched an attack on the front Maeda Keiji army in three ways, facing the Fukushima army that was several times his own, Maeda Keiji was not afraid at all, brandished a red gun, and rode his horse to the west of the enemy's east, causing dozens of casualties of the Fukushima army for a while, and the Uesugi army also forgot their fear when they saw this, and rushed to the ground formation, struggling to block the attack of the Fukushima army.

With the bravery of Keiji Maeda, the Uesugi Army basically stabilized the position of Kitagawahara, and even suppressed the Fukushima Army along the north shore and could not move for a while. At this time, Kuroda Nagamasa and Hosokawa Tadashiko, who were unwilling to be the sole merit of Fukushima Masanori, decided to cross the river to "support" the friendly forces.

The support of 8,500 troops was a great encouragement to the Fukushima Army, but it was a catastrophe for the Uesugi Army, which was already struggling to support it. As soon as he landed on the shore, one of the "Japanese Seven Pillars Spear", one of the "Japanese Seven Pillars Spear", the mother Sato Yushin under the crotch of the red horse, holding the Japanese horn, roared and led the samurai under his command to rush into the Uesugi army position, as soon as he took over the battle, he picked and killed Maeda Keiji's retainers Mizuno Fujibei and Usamiya Goemon, seeing that the two veterans died unexpectedly, Maeda Keiji was annoyed and angry, and rode his horse to the front of the battle to discuss with Musato Yushin, but before Musato Yushin could fight, he was hit by the Kuroda army's iron cannon foot and fell off the horse, and the Uesugi army immediately stepped forward to protect Maeda Keiji and withdrew from the battlefield when he saw this.

The Uesugi army, which had lost Maeda Keiji, was leaderless, and under the impact of the Toyotomi army, which was several times its size, it quickly disorganized its formation, and abandoned the first barrier one after another, and gathered towards the Chunyen Tadabe behind the second barrier.

At the same time, the progress of Minamimachi was also very smooth, the Jindai Mizuhara Jinken was killed by Otani Yoshitsugu's iron cannon Ashigaru on the horse, Kyogoku Takaji's 6,000 troops advanced all the way, broke through two anti-horse fences in a row, and after killing nearly half of the Suwon army, he clashed with Kurokawa Weishi, and the two armies fought for a long time, coinciding with Otani Yoshichi coming to support after destroying the main position of the Mizuwon army, and finally defeated Kurokawa Weishi, forcing the latter to retreat towards the area of Hirayamaso, and the first phase of the western route strategy was successfully completed.

Compared with the step-by-step advance of the two roads in the middle and west, the slow movement of the four regiments with 23,000 people is surprising, because the relatives of the Nagazong and my department are interested in preserving their strength, and they do not fill in the earth and pave the road like the middle and west roads, but plan to wait for the military strength of Inomata Village to help Maeda Keiji before crossing the river by boat, who knows that the Uesugi army did not plan to go to Kitagawa Hara but stubbornly held the position, which made the Nagamune and my department Mori very embarrassed. Yoshimasa Tanaka and Hideaki Kobayaka, who were as intent on preserving their strength as he were, insisted on staying at Sugawara Shrine and waiting for Utagawaso's Nagamune to cross the river before taking action.

Finding that there was something unusual about Nagamune's family, Fukushima Takayoshi, who was in charge of monitoring the eastern road in Tenjinso, immediately made a decision, and ordered the three pioneers of the Tosa army, Wasuka, Ikoma, and Kato, to move closer to the main camp of Nagamune's department, and sent an envoy to the Tosa army, asking the Mori family to immediately organize an army to force the Yukawa River.

Forced by the situation, Changzong and my Sheng Qin had no choice but to attack the Uesugi army, and it took nearly two hours and 300 troops to reluctantly fill in the earth.

Knowing that the Tosa army had moved, Kobayakawa Hideaki, who had 13,000 men, had no reason to delay, but because the strength of the Inomata army was attracted by most of the Tosa army, the landing of the Kobayakawa army did not encounter fierce resistance, but on the contrary, it only sacrificed less than 100 men to gain a foothold on the north bank, and united with the Tanaka army to kill the village of Inomata from the southeast.
