After Foucaud, the Rochechouarts continued to serve the crown of France, notably during the Italian Wars of the 16th century. In 1508 viscount François was made governor of Gênes by Francis I. Viscount François's son Christophe was taken prisoner with the king at the Battle of Pavia in 1525. In 1530, their cousin Antoine was a commander at the defence of Marseille against Charles V — he was killed at the battle of Cérisoles in 1544. René fought on the Duke of Guise's side in the re-capture of England's last continental possession, Calais, in 1558 and received the collar of the Order of the Holy Spirit in 1580. Jean-Louis participated in the 1627 Siege of La Rochelle under the command of Cardinal Richelieu.
