Yonekura Shigetsugu was a famous Japanese samurai and a member of the Takeda clan.
Biography
Shigetsugu was a retainer of Takeda Shingen and servant of Amari Haruyoshi. He was killed during the Battle of Nagashino and is remembered for his participation in both the Battle of Kawanakajima and the Battle of Nagashino in 1575. During the Battle of Nagashino in 1575, both the Tokugawa clan and Oda Nobunaga sent troops to alleviate the siege, and Takeda Katsuyori was defeated. The victory of Oda's Western-style tactics and firearms over Takeda's cavalry charge is often cited as a turning point in Japanese warfare; many cite it as the first "modern" Japanese battle. Yonekura Shigetsugu rushed the Takeda flank singlehandedly before he was killed by gunfire. His corpse was later impaled on a pike by Nobunaga's forces. Following the battle, Nobunaga continued henceforth until he had effectively established control over all of Japan. Yonekura's death poem is often performed in Noh plays to this day, and is a prime example of the Haiku form in death poems. While death poems did not adopt any prescribed form as far as syllables, tone, and length were concerned, it was usually required to be short, be pertinent, and invoke pathos in the listener. It did not need to rhyme and considering the fact that most Japanese singing was expected to be discordant and erratic, this is not surprising. The flexibility of the death poem was in direct contrast with the rigid caste system that pervaded Japanese life during that period of time. Shigetsugu was part of the crucial Nagashino cavalry counter. As far as typical military strategy is concerned, whether or not a cavalry charge is successful depends on the enemy infantry breaking ranks in order for the cavalry to mow them down. However, when the enemies' infantry does not break rank and scatter, the cavalry charge will often fail, since trained warhorses refuse to advance into solid masses of soldiers. By opposing their adversaries' traditional tactics in this way, Takeda Katsuyori's forces hoped to rout the cavalry charges. They failed. His master, the late Amari Haruyoshi, was a famous Takeda samurai. Believed to have been born in 1533, Masatada was the eldest son of Amari Torayasu and a servant of Takeda Shingen. He fought at Kikyôgahara, where the Ogasawara incurred a severe reversal at the Takeda's hands. He also served at the battles of 4th Kawanakajima, Usuigatoge, and Matsuyama. He was killed in a riding accident in 1564; As he was riding, he sustained an injury and was unhorsed. As he lay on the ground, he attempted to stem the flow of blood that came forth from the wound. While he was distracted, he failed to notice his horse until it was right on top of him, trampling him. He is probably most widely known for an incident involving one of his wounded retainers. When the man's bleeding did not abate, Masatada advised him to drink horse feces mixed with water to help accelerate the formation of blood clots. When the wounded man hesitated to consume raw horse dung, Masatada himself consumed some of the concoction. Encouraged, his retainer drank from the same cup and was reported to have recovered.
