But a miracle vanishes when closely observed.

And they had the damsel before their very eyes.

They perceived that good and saintly as she was, she wielded no supernatural power.
While the men-at-arms and all the common folk welcomed her as the maid of God and an angel sent from heaven for the salvation of the realm, these good lords thought only of profiting from the sentiments of confidence which she inspired and in which they had little share.
Finding her as ignorant as possible, and doubtless deeming her less intelligent than she really was, they intended to do as they liked with her.

They must soon have discovered that it was not always easy.
She was a saint, saints are intractable.

What were the true relations between the Royal Council and the Maid?
We do not know; and it is a mystery which will never be solved.
