Who were the Stanley brothers who helped Henry vii at bosworth field?

The Stanley brothers, William and Thomas Stanley, played a crucial role in the Battle of Bosworth Field in 1485, which was a decisive confrontation in the Wars of the Roses. William Stanley, the more influential of the two, commanded a significant force and initially hesitated to engage in the battle. Ultimately, at a critical moment, he chose to side with Henry Tudor (Henry VII), leading to Richard III's defeat. Their support was pivotal in securing Henry's claim to the throne and establishing the Tudor dynasty.
