In the lead up to the battle of Bosworth Richard III was the much stronger candidate to win over Henry Tudor, Richard had over double the number of runners that Henry did and he also had all of England's resources at his fingertips to help supply his army while all Henry had was the unconfirmed support of Lord Stanley which if he did not have he would most definitely lose. As it came to the battle Stanley still hadn't chosen which side to support and so Henry was very worried about how the battle would turn out as he was seen to be the weaker side and for the majority of the battle it did seem as though Henry would lose. The battle only started to turn in Henry's favour when Thomas Stanley decided to back him and helped him fight against Richard.
