He is regarded as one of the Four Guardians of the Tokugawa (Tokugawa-Shitennō).[1] along with Honda Tadakatsu, Ii Naomasa, and Sakakibara Yasumasa.[2][3] He also included in another cultural depiction as one of Tokugawa 16 divine generals(Tokugawa jūrokushinshō).[4][5]

Early life edit

Tadatsugu was born in 1527 to Sakai Tadachika, a hereditary vassal of the Matsudaira clan of Mikawa Province.[2]

When Tadatsugu came of age, he first served Tokugawa Ieyasu's father, Matsudaira Hirotada. Tadatsugu was the husband of princes Usui and Keyoin, a sister of both of Ieyasu's parents and hence Ieyasu's uncle-in-law.

It is said that after Hirotada's death, in 1551 Tadatsugu served young Ieyasu and led a hostage life in Sunpu.

Service under Ieyasu edit

In 1556, According to the records from Tosho Gunkan, Tadatsugu defends Fukutani castle which besieged by 2,000 cavalry troops of Oda clan led by Shibata Katsuie. Tadatsugu manage to repel the invaders as he led a sallying forces outside the castle to engage Katsuie troops.[6][7][8][9][10]

In 1558, Tadatsugu accompanied Ieyasu in the Siege of Terabe.[citation needed]

In 1560 at the Siege of Marune against Oda clan.[citation needed]

In 1563, in the Mikawa Ikkō-ikki uprising, Tadatsugu faithfully followed Ieyasu while many of the Sakai Clan contributed to the uprising.[citation needed]

Later in 1564, Tadatsugu lead an attack towards Yoshida Castle, forcing the lord of the castle, Shizumi Obara, to escape and the castle surrender without a fight.[11] Then in the same year, before the Battle of Azukizaka, Tadatsugu wrote letter to the Ikko-Ikki faction in Mikawa, chastising their rebellious conduct.[12]

After 1565, when Ieyasu broke off his ties with the Imagawa clan, Tadatsugu was given command of the Yoshida Castle.[13] in eastern Mikawa (present-day Toyohashi).

By 1567, the majority of daimyō forces in the Tokugawa armies were organized in two divisions, each with a separate commander. Tadatsugu was placed over the forces of 18 Tokugawa daimyō-vassals and his counterpart, Ishikawa Kazumasa, was given command over the forces of 13 daimyō-vassals.[14]

Sometimes around 1565, After the Tokugawa clan captured Yoshida Castle in Mikawa, Ieyasu appoint Tadatsugu to control the castle.[15][16]

In 1570, Tadatsugu were involved in the Battle of Anegawa, where The Tokugawa forces forming the left wing of the Oda and Tokugawa alliance forces. Here, Tadatsugu and Ishikawa Kazumasa leading the vanguard, while Sakakibara Yasumasa and Honda Tadakatsu leading the rearguard of the Tokugawa formation.[17]

In 1572, during the Battle of Mikatagahara, Tadatsugu secured the Tokugawa's right flank, seeing his troops being badly beaten by the opposing Takeda forces; and when Ieyasu and his allies retreated to Hamamatsu Castle, Tadatsugu participated in the ruse which mitigated the effects of Takeda victory in the field; and the Takeda forces withdrew.[18][19]

In June 1574, when the Takeda clan laid siege to Takatenjin, Oda Nobunaga personally lead reinforcements where he encamp in Yoshida castle, as he greeted by Tadatsugu. However, as he heard Takatenjin surrendered, Nobunaga abort his trip to Takatenjin and return to Yoshida castle to decide next step.[20]

In 1575, during the Battle of Nagashino, he led a successful night attack against the Takeda along with Kanamori Nagachika.[23][24] For his deeds defending a castle in Tobinosuyama mountain after the battle of Nagashino, Oda Nobunaga rewarding Tadatsugu with a jinbaori(Samurai commander's jacket),[25] and also a Maki no Tachi(sword's mounting).[26]

In 1578, Tadatsugu's son, Sakai Ietsugu (1564–1619), took over his father's role as castellan of Yoshida Castle.[13] The ie- in the beginning of Ietsugu's name was a special honor bestowed by Tokugawa Ieyasu, a special reward for special vassals, allowing them to use one of the kanji from his Nanori name.[27]

In 1584, during the Battle of Komaki and Nagakute, he successfully turned back a move by Toyotomi Hideyoshi forces against Kiyosu Castle, which was led by Toyotomi commander Mori Nagayoshi. Tadatsugu scouted Nagayoshi forces during their march, then as Nagayoshi rest and camp his soldiers Hachimanbayashi area, Tadatsugu joined Okudaira Nobumasa and Matsudaira Ietada (Fukōzu) in Komaki to launch the attack at dawn. As they pushed Nagayoshi forces, Tadatsugu tried to encircle Nagayoshi forces from the flank, which ultimately failed as Nagayoshi manage to breaking through the encirclement and retreat.[28]

In 1586, according to "Sakakibara clan historical records", Ieyasu sent Honda Tadakatsu, Sakakibara Yasumasu, and Ii Naomasa as representatives to Kyoto, where three of them being regarded as "Tokugawa Sanketsu"(Three great nobles of Tokugawa).[29] Then in following month, the three of them joined by Tadatsugu Sakai to accompany Ieyasu in his personal trip to Kyoto, where the four of them "became famous".[29]

In 1590, during the Odawara Campaign, Tadatsugu was ordered to accompany Tokugawa Hidetada, Ieyasu's son and heir, to Kyoto, where he served as hostage for Ieyasu's loyalty to the Toyotomi during that campaign. After the battle, Hideyoshi ordered to Tokugawa clan to relocate from their ancestral holdings to the Kantō region. Tadatsugu went into retirement, but his son Ietsugu received a 30,000 koku fudai fief at Usui, in Shimōsa Province, and Tadasugu accompanied them there.[13]

Death edit

Tadatsugu died in Kyoto in the winter of 1596. After Tadatsugu's death, the Sakai clan continued to prosper. In 1604, his descendants moved to Takasaki Domain (50,000 koku) in Kōzuke Province; in 1616, they relocated to Takata Domain (100,000 koku) in Echigo Province; in 1619, they were transferred to Matsushiro Domain in Shinano Province; and then, from 1622 through to 1868, they were installed at Tsurugaoka Domain (120,000 koku) in Dewa Province.[13] The head of the Sakai clan was ennobled as a "Count" in the Meiji period.[13]
