" Was Charles I too stubborn to listen to reason? Could Civil War have been averted if the king had been more willing to negotiate? His great enemy Cromwell always maintained that the king had been swayed at the last moment by his queen, the beautiful Henrietta Maria. We can believe Cromwell's claim that the queen told her husband to be firm. But the wicked, spiteful, altogether irresistable quote often attributed to her by Puritan writers of the time is almost certainly false.
"Oh my love, if you cannot remain firm in the bedchamber, at least try to remain firm with your subjects! "
― Antonia Fraser , Cromwell
