At the age of nineteen, Mr. Kitajima served Yuan. At the age of twenty-one, he showed his innate ability to deal with people and things, attracted the attention of his father and family officials, and inherited the position of master after his father died. Shortly after Shikang of Kitajima succeeded to the throne, Sugiyama Yamauchi and Ding Chao of Fangu Sugiyama joined forces with 80,000 troops to launch a large-scale attack on the Kitajima family. HūjūTsunashige sent by Kato Shikang defended the Musashi River and crossed the city. After days of siege, allied morale began to decline. Kato Shikang followed the Allies with 8000 soldiers and launched a general attack with the garrison at night. Allied defeat, Yamauchi, Gu Duo famous soldiers were killed. This campaign was the "Battle of Crossing the River", one of the three surprise attacks in Japan during the Warring States Period. Since then, the North Island family has been established in the Kanto world. After more than 30 years, Takeda's policy of merging with foreign countries began to shift to diplomacy, and Takeda formed an alliance with Imakawa. After the first war between the government and Taiwan Province, North Island won, but at this time, Shangshan Chinobo led the army south. Shikangbei Island, which had been prepared for this, saw the intention of going to the Chinese fir decisive battle and led the national army to stick to Odawara City. Nobuyuki Shangshan was helpless and left Kanto in a hurry.
Shortly after the Battle of Odahara, Mr. Kitajima handed over his possessions to his eldest son, hūjūuji masa, who lived in seclusion in Izu Peninsula, but actually held the real power of the Kitajima family. Yuan Gui died in Odawara City in the second year (157 1) at the age of 57.
In the fourth year of astronomy (1535), Shi Kang married Rui Xiyuan, the daughter of He Jun's relatives in Jinchuan. The subordinate relationship between the Kitajima family and the Imagawa family since the early cloud era has been replaced by equal political marriage. Since then, the relationship between the Kang couple has been very good. Even if the relationship with Imakawa deteriorates in the future, this relationship has not been affected. They had 12 children after marriage. Many children build the future of northern families by adopting children or getting married. When these children grow up, no one will kill each other for the right to decide, which is rare in the cruel Warring States period. At least from this perspective, the achievements of Ruixiyuan can't be erased.
156 1 year (four years in Lu Yong), Shang Shan * * inherited Shang Shan clan leader hu zheng (later "Kenshin") and sent troops to Kanto in the name of supporting orthodox Kanto Gong and Ashikaga Fujitsu; The former ministers of Shangshan and the anti-Beitiao forces in all parts of Kanto responded in succession, assembled into an unprecedented army claiming to be more than 100,000, suppressed a number of strongholds, including Furukawa Imperial, and replaced Yi Shi with Fujishi as the Kanto Communist Party. Kang and his son led the army to stick to Odawara City; Because the city is strong, the whole army is determined, and the attacking Shangshan army finally quits in vain. After hu zheng officially took office as Guandong Pass in Kamakura Hachiba Palace, he had to retreat to the north under the unfavorable conditions of attacking Odawara City, disharmony between generals and poor food and grass. The northern army pursued the situation and won regional victory. After Shangshan's tiger retreat from Kanto, the northern scholars gained great fame and gradually gained the upper hand in the struggle for the dominance of Kanto. 1562 (the fifth year of Lu Yong), the northern army suppressed the ancient river imperial house again, and the Ashikaga family was taken into exile in Odahara, and the final fate was unknown.
1563 (in the sixth year of Lu Yong), Takeda Army, which won a strategic victory in the fourth battle of Chuanzhong Island, attacked Matsuyama City, the stronghold of Musashi Shangsu Family; At the invitation of Hu Hui (later renamed by hu zheng), Satomi Yoshitaka sent Hongyi to lead troops to the rescue. Although it broke through the blockade of the northern army and entered the border of Musashi, it had to be withdrawn because of the fall of Songshan City. The following year, in order to support the Edo garrison commander Yasuji Ota, who rebelled against the Kitajima family, Hony led an army of1.2000 people to occupy Taicheng, the national government that lived on the border of Musashi. Shi Kang, Gangcheng and others led 20,000 troops to confront them, and it was difficult to win or lose (the second battle between the government and Taiwan). Later, the influence of the northern family went deep into the general manager. 1567 (the tenth year of Lu Yong), Shi Kang instigated Takahiro, the owner of Ueno's stable bridge and a member of the Shangshan family, to rebel, which made the humble Kanto strategy of Shangshan fall into a tight encirclement. However, in the Battle of Sanchuanshan in the same year, the northern army commanded by Zheng Shi was defeated by Li Jianjun commanded by Hongyi. The influence of the North Island family in Fangzong Peninsula was once again frustrated. At this time, the situation in East China Sea Road changed greatly, which led to the disintegration of the three countries and affected the power relations in the East. Prior to this, Imagawa Yoshimoto died in a narrow space in the tail of Zhang Tong, and Tokugawa Ieyasu, the owner of Okazaki City, Sanhe, became independent. Today, the foundation of the family's dominance of Tokaido began to shake. In order to seize the territory of Donghai Road, Takeda Shingen did not hesitate to force the righteous to death. Finally, in 1568 (11th year of Lu Yong), he sent troops to attack Hejun. Tokugawa Ieyasu also sent troops from Sanhe to attack Yuanjiang. Although Shinji, the new leader of the Chuanjia family, has formed an alliance with Kenshin Sugiyama and mobilized1.5000 troops, it is still difficult to resist the invasion of Takeda and Tokugawa by himself. Lai's political relatives led 45,000 troops to intervene forcibly, forcing Takeda Army (18,000 troops) to retreat. Taking this opportunity, the Kitajima family reconciled with Uesugi Kenshin, and concluded a "Meeting Alliance" on the condition that Shikang Seven Men became Kenshin's adopted sons (the future Uesugi Jinghu); North Island Gaoguang returned to Shangshan's home. 1569 (12th year) In October, he led an army of 20,000 to attack Odawara City, and Kang and his son decided to garrison Cage City. Takeda captured the city gate and saw that he could not break the city and retreat. His political relatives led an army to chase more than 20,000 people, ordering them to be responsible for guarding History Street and Rank Father's Office, and his state assembled another 20,000 troops with the intention of defeating Takeda Army. Unexpectedly, Zhao Shi and Shibang fought with Takeda Army at Sanzengdong Pass in the northern territory of Sagami and were defeated by Takeda Army. When Zheng Shi heard the news, he immediately withdrew and returned to Odawara City (the Battle of Sanzengdong). Takeda army seized Jun River, and today's Sichuan family perished under the attack of Takeda and Tokugawa. Therefore, Kitajima teamed up with Sugiyama Imagawa, and the strategic concept of balancing Takeda fell through. The battle was frustrated, and the North Island family strengthened their defense against Garfield. It is believed that the famous "Gougou" (the outermost fortifications around Waiguo and some Shimonomachi), that is, the nine kilometers around Odawara City, and the construction of the G8 city are all caused by this. The effect of China-Vietnam alliance is not as good as expected. Liu Chang, Satake Yoshishige and others are famous for their anti-North Island. They joined hands with Takeda to continue their anti-North Island campaign, thus enhancing Takeda Shingen's influence in Kanto in vain. In view of this, Connor decided to re-examine its alliance strategy. 157 1 year 10/2 1 day (October 3rd, 2nd year of Yuanguili), Shi Kang died in Odahara at the age of 57, leaving behind his last wish to give up the alliance with Vietnam and reconcile with the Takeda family. Soon, Zheng Shi re-allied with Takeda family according to his father's orders, and accepted the fact that Takeda family ruled and ruled. Since then, Kanto has returned to the pattern of Takeda in Kitajima joining hands to fight against goodness.
Shi Kang died of illness.
In the first year of Yuangui (1570), Shi Kang, who knew that time was running out, left a will in his hospital bed to "give up the Yuetong Alliance and re-form an alliance with Takeda". On October 3rd, the second year of Yuan Gui (157 1), Shi Kang died of illness at the age of 57. Dharma name Dongyang Daizong Buddhist Grand Temple.
As mentioned above, Shi Kang is a famous scholar with both civil and military skills, and he has never been defeated since he was 16 years old. Although this is related to his late stay in the city to take charge of the overall situation and rarely participate in the joint war, it can also reflect his bravery in fighting to a certain extent. Shi Kang paid attention to pacifying people's hearts and established an excellent retainer group, which was indeed worthy of being an excellent civil servant and strategist at that time.
There is a letter written by Shi Kang to Bajiulang (later Shangshan Kyoto) in the 11th year of Lu Yong. The letter mentioned Saburo's past drinking and sinking, and Shi Kang's kindness as a father. This fully shows that Shi Kang is a man.
