Her original tendency to intemperance had so much increased, that she was often unable to stand on her feet.

A bottle of wine, holding more than a quart, in the morning, and another in the evening, together with a pound of sugar, was her usual allowance.

She addressed letters to Alva complaining that her husband had impoverished himself "in his good-for-nothing Beggar war," and begging the Duke to furnish her with a little ready money and with the means of arriving at the possession of her dower.
An illicit connexion with a certain John Rubens, an exiled magistrate of Antwerp, and father of the celebrated painter, completed the list of her delinquencies, and justified the marriage of the Prince with Charlotte de Bourbon.

It was therefore determined by the Elector of Saxony and the Landgrave William to remove her from the custody of the Nassaus.

This took place with infinite difficulty, at the close of the year 1575.
Already, in 1572; Augustus had proposed to the Landgrave that she should be kept in solitary confinement, and that a minister should preach to her daily through the grated aperture by which her, food was to be admitted.
The Landgrave remonstrated at so inhuman a proposition, which was, however, carried into effect.
