Information: - , also known as Sait Toshimasa, was a Japanese samurai during the Sengoku period. - Sait was the son of Sait Dsan, however, rumors that Yoshitatsu was in fact not Dosan's real son (that is, that he was actually Yorinari's son) persisted and Dosan apparently began to think of naming one of his other sons, Nagatatsu, as heir. Yoshitatsu had come to suspect his father's intentions. Though he actually did suffer from leprosy, Yoshitatsu feigned illness and murdered his two younger brothers in 1555 and declared war on Dosan. In May 1556 Yoshitatsu led an army to the Nagaragawa river, prompting Dosan to take up a position on the opposite side of the river. Yoshitatsu's vanguard opened the attack by crossing the river and cutting deeply into Dosan's ranks. They nearly reached Dosan's headquarters before being savaged by a counterattack. Yoshitatsu then led the bulk of his forces across the river and in the course of the fighting Dosan was killed. Yoshitatsu thereafter assumed control of Mino. He proved a capable commander and was able to defeat attempts by Oda Nobunaga to avenge Dosan's death, but died of his illness in 1561. - Oda Nobuhiro ( , died October 13 , 1574 ) was the eldest son of Oda Nobuhide . After Nobuhiro 's father took Anjo Castle in Mikawa Province in 1540 , the castle was given to Nobuhiro . During 1549 , Nobuhiro was trapped by the Imagawa clan , but was saved when the Oda clan handed over one of their hostages -- Matsudaira Takechiyo , later known as Tokugawa Ieyasu to make up for not lifting the siege of Anj . As Nobuhide 's illegitimate son , Nobuhiro 's power would slowly fade and always be looked down upon by his younger brother Nobunaga and even by many of his own retainers . Afterwards , Nobuhiro was forced to step down as the head of the Oda to allow Nobunaga to be the new head . Later on , Nobuhiro plotted against Nobunaga with the assistance of Sait Yoshitatsu . Their scheme was uncovered before any damage was brought upon anyone , and Nobunaga forgave Nobuhiro . Nobuhiro ended up getting killed later on the 13th of October fighting the Nagashima monto .
