Philippa Gregory said this quote
“ My father says there are more than twenty thousand turned out for the king. It seems that most men think that we will win, that York will be captured and killed, though the king in his tender heart has said he will forgive them all if they will surrender.~Will there be another battle?~Unless York decides he cannot face the king in person. It is one sort of sin to kill your friends and cousins, quite another to order your bowmen to fire at the king's banner and him beneath it. What if the king is killed in battle? What if York brings his broadsword down on the king's sanctified head? ”
