Turning his gaze back to Hokuriku for the time being, on the third day of the fourth month, that is, the same day that Motomasa Amano arrived in Fushimi, Maeda Toshimasa led an army of 20,000 troops from Kanazawa Castle, because the fortress defense of Komatsu Castle was strong and difficult to capture, Maeda's army deliberately detoured and deployed in Matsuyama Castle on the fifth day of the first month of April, intending to attack the lonely castle Daishonji Temple, and then cut off the connection between Echizen and Niwa Nagashige and then forced the Niwa clan to surrender. And the lord of Daishoji Temple, Yamaguchi Masahiro, was anxiously waiting for the rescue of Niwa Nagashige, the lord of Komatsu Castle, but no army had arrived except for the initial 2,000 reinforcements.

The next day, Maeda Toshimasa sent Kuri Kuro Guard and Murai Kuzaemon as envoys to advise the Daishoji Castle to surrender, but the Yamaguchi father and son, who were defending the castle, immediately refused, and Toshinaga had no choice but to start attacking the castle. Yamaguchi Masahiro's son, Ryo Ryo Shuhiro, laid an ambush on the way, but was discovered by Yamazaki Nagatoku, the vanguard of the Maeda army, and the curtain of the battle began.

After Yamazaki Nagatoku attacked, Nagaren Ryu soon joined the battle, and a fierce battle began. During the battle, Yamaguchi Shuhiro miscommanded, and was broken up by the Maeda Army's iron artillery troops, and had to retreat into the city with a loss of nearly 1,000 troops, and the ambush battle also turned into a siege battle.

At first, the defenders of Daishoji Temple were fearless in front of Maeda's army, and they fought quite resolutely and tenaciously. However, the Maeda soldiers were outnumbered, and they still had an advantage compared to the high morale of the defenders. 20,000 against 3,000, who can resist it?

Three days after the storm, Masahiro Yamaguchi had no choice but to express his willingness to surrender on the wall, but Maeda Toshimasa flatly refused on the grounds that he "did not surrender as soon as possible", and at noon that day, Maeda's army attacked the castle. Ushuhiro Yamaguchi, who was in charge of the defense of Waimaru, fought to the point of exhaustion, and committed suicide by drawing his sword after signing up in front of the Yamazaki Chotoku Formation. Yamaguchi Masahiro was not reconciled, and did not kill himself until the next morning, after Honmaru was breached. Since then, the city of Daishonji has been captured. The remains of Yamaguchi's father and son were buried by Maeda Toshimasa on the side of the Fukuda Bridge at the foot of the castle, and the stone tablet was passed on; Yamaguchi Masahiro's second son, Hironori Yamaguchi, escaped and went to Omi Sawa Yamashiro to seek refuge in Ishida Mitsunari under the escort of several retainers.

After that, Maeda Toshimasa saw that Echizen was weak, so he changed his plan to invade Echizen south, and the lord of Maruoka Castle, Aoyama Munekatsu, hastily responded to the battle, and on April 12, Aoyama Munekatsu ran out of ammunition and food and was forced to ask for peace with the Maeda army. Maeda Toshimasa took a short rest in the castle and prepared to take Katsuyama Castle in one fell swoop, Niwa Nagashige's brother Nagamasa, as long as Katsuyama was captured, he would be able to join forces with Oda Hideo of Ohno Prefecture and Oda Hidenobu of Mino, and then unite with Gotoyama Castle to divide and surround Nishimino and Higashi-Omi, thus annihilating the small daimyo of the pro-Tokugawa region one by one.

However, just as the war was going well, Maeda Toshimasa suddenly received an urgent report that Fushimi had fallen and that the Mori army was marching on Mt. Gotoshi, and Joshiro Ogasawara Takakiyo pleaded with Toshimasa for speedy support. In a hurry. Maeda Toshimasa had no choice but to give the task of attacking Katsuyama Castle to Oda Hideo. He led 20,000 soldiers south. Advance along the Hokuriku Road to Kinai.

However, it rained overnight, and the army had not yet arrived at Kitasho Castle, but received an urgent report from Kanazawa Castle that Niwa Nagashige had sent troops to attack Kanazawa on April 13. And the defense in Kanazawa Castle was empty and difficult to resist. This sudden military situation put Maeda Toshimasa in a dilemma, whether to go south to support Gotoyama and fight against the Maori army to pacify Kinai, or to return to Kaga to eliminate the Niwa clan first and then go south, Maeda Toshimasa in Echizen could not make up his mind for a while, but was delayed for two days, and finally Maeda Toshimasa decided to return to Kanazawa Castle under the efforts of the elder of the family, Renlong.

From the seventh day of April to the seventh day of April, he received a letter for help from Yamaguchi's father and son, and on April 13th, Niwa Naga resent his troops. Six days passed, and Komatsu Castle was not far from Daishoji Temple, and it only took one and a half days to march in a hurry, but the Niwa clan gave up the original intention of supporting Daishoji Temple, and allowed Yamaguchi and his son to commit suicide in defeat, and Aoyama Sokatsu Kaejo surrendered. This is seen by outsiders as an attempt to protect oneself. But in fact, it was caused by the disagreement in the Niwa family.

Niwa Nagashige made a desperate attempt to side with Tokugawa Ieyasu in order to restore his family business, and although he won the support of the Niwa clan, he was opposed by the elders of the family led by Eguchi Masayoshi. The elders of the family think that if there is no power to shake the Toyotomi clan today, the mighty 150,000 Aizu crusade army is proof that even if the inner government is strong, it is only 80,000 troops at most, plus the Uesugi army is less than 110,000, and there are Mogami and Date in the north of Uesugi United, and there are powerful daimyo surveillances such as Utsunomiya, Gamu, Ikeda, and Asano around, and the military strength of these daimyos is not included in the 150,000 people, that is to say, the entire Kanto region, is Tokugawa, Uesugi's 100,000 men fought against nearly 200,000 led by Hideho, who had a righteous reputation, and the result can be imagined.

Even if the Niwa clan and the Maeda army formed a confrontation in Hokuriku, it would not be able to affect the overall situation of the Kanto region at all, and when the time came, the Tokugawa Uesugi family would be wiped out, and Hideho would be able to wipe out the Niwa clan from Japan by turning around.

However, Niwa Nagamasa, who was pro-Tokugawa, disagreed with the advice of the elders, and he said to Niwa Nagashige: "The inner government has informed the family that some of the daimyo in the crusading army of the right house have secretly reached a tacit agreement with the inner government, and once the war starts, these daimyo will meet the opportunity to rebel, and then the crusading army will be in chaos, and the inner government and Aizu Nayan can take the opportunity to break into the army and take the head of the right house, and capture the thief first to capture the king's right house and die. Moreover, now that Anyi Nayan has gone to Luo, and Fushimi has also been captured, as long as he can hold back the Maeda army and buy time for the Maori army, when he takes the castle of Gotoyama, he will be able to connect with Nishimino, and then our army will be passive and active, and dominating Hokuriku is just around the corner! ”

"Capture the thief and capture the king first?" Eguchi Masayoshi sneered, "How can you approach at will with the five-colored Beibei Guardian next to Youfu, Beizhong Shou is still too naïve." ”

Niwa Nagamasa wanted to argue with him, but was reprimanded by Niwa Nagashi, who thought for a long time and said calmly: "Kanto will be a battle to the death anyway, but the family has already promised the Tokugawa family, if the Tokugawa is defeated in the end, even if the army is not dispatched, the family will not be able to escape the involvement, and besides, two thousand troops have been sent to the Daishoji Temple, which proves the attitude of the family, this road ...... There's no going back. Speaking of this, everyone present was silent, yes, regret should not have been at the beginning, even if it was to remain neutral, it would not be worried about the future of the Niwa family, now the arrow is on the bow, and it has to be sent, only to fight to the death, buy time for the Maori army, and maybe there is a chance of victory.

After a war of words, the two factions in the family did not give in to each other, and finally Niwa Nagashige decided to attack Kanazawa Castle while the main force of the Maeda army invaded Echizen to buy time for the Mori clan in, which is why the main force of the Niwa army was not dispatched until April 13.
