Okudaira Sadamasa (1555 - 1615)

The Okudaira family were originally retainers of the Tokugawa, but were forced to join Takeda Shingen. After Shingen died and Katsuyori assumed leadership of the Takeda clan, Okudaira Sadamasa walked his men right out of Tsukude Castle and rejoined the Tokugawa. Katsuyori had Sadamasa's wife and brother -- hostages to the Takeda -- crucified for this.

Ieyasu accepted Sadamasa back and entrusted him with the defense of Nagashino Castle.
