Boleyn, I have been thinking about this one. Once Margaret knew that Henry was on his way to take the crown, I cannot imagine her not trying to influence Stanley. From what I have read about Stanley, it is hard to say what he was thinking. He changed sides often during his career. His loyalty seems to be connected to his own self preservation. He tried to always pick the winning side. This time he happened to choose the same side as his wife. Did she influence him, sway him to Henry’s side? I think he waited to see how the battle would go before he made his final decision. I could be wrong, but he is not someone I would trust to be loyal on the field of battle.
