Matsudaira Tadayoshi

Matsudaira Tadayoshi (松平 忠吉, 18 October 1580 – 1 April 1607) was the fourth son of Tokugawa Ieyasu with his concubine Saigo-no-Tsubone.

When his mother died, he and his brother were adopted by Acha no Tsubone (1555-1637).

Later, Tadayoshi was adopted by Matsudaira Ietada and succeeded him as the second lord of Oshi Domain.

At the Battle of Sekigahara, he was attended by Ii Naomasa and was therefore at the forefront of the fighting.

In the midst of the battle, he was shot by an Ishida gunner, but survived with a bullet wound.
