In 1521, he served under
Chevalier Bayard in the
Siege of Mézières in the
Ardennes, and in 1524 he commanded a company of
gendarmes in the
Defense of Marseille against the Imperial forces. In 1544, he commanded the French forces in the Piedmont but when he allowed the town of
Carignano to fall to the enemy, he fell into disgrace and was relieved of his command. On the nomination of the
Count of Enghien as his replacement, he took part under the orders of this new general in the
Battle of Ceresole, where he won fame through his skillful use of the
cavalry charge. He ended his military career in fighting the English during the
French invasion of the Isle of Wight in 1545. ==References==
