ere arrested and Biron
was executed. Auvergne after a few months' imprisonment was released,
chiefly through the influence of his half-sister, his aunt, the
duchess of Angouleme and his father-in-law. He then entered into
fresh intrigues with the court of Spain, acting in concert with
the marchioness of Verneuil and her father d'Entragues. In 1604
d'Entragues and he were arrested and condemned to death; at the same
time the marchioness was condemned to perpetual imprisonment in a
convent. She easily obtained pardon, and the sentence of death against
the other two was commuted into perpetual imprisonment. Auvergne
remained in the Bastille for eleven years, from 1605 to 1616. A decree
of the parlement (1606), obtained by Marguerite de Valois, deprived
him of nearly all his possessions, including Auvergne, though he still
retained the title. In 1616 he was released, was restored to his
rank of colonel-general of horse, and despatched against one of the
disaffected nobles, the duke of Longueville, who had taken Peronne.
Next year he commanded the forces collected in the Ile de France, and
obtained some successes. In 1619 he received by bequest, ratified in
1620 by royal grant, the duchy of Angouleme. Soon after he was engaged
on an important embassy to Germany, the result of which was the
treaty of Ulm, signed July 1620. In 1627 he commanded the large forces
assembled at the siege of La Rochelle; and some years after in 1635,
during the Thirty Years' War, he was general of the French army in
Lorraine. In 1636 he was made lieutenant-general of the army. He
appears to have retired from public life shortly after the death of
Richelieu in 1643. His first wife died in 1636, and in 1644 he married
Francoise de Narbonne, daughter of Charles, baron of Mareuil. She had
no children and survived her husband until 1713. Angouleme himself
died on the 24th of September 1650. By his first wife he had three
children: Henri, who became insane; Louis Emmanuel, who succeeded his
father as duke of Angouleme and was colonel-general of light cavalry
and governor of Provence; and Francoise, who died in 1622.
