Battle of Agincourt, once again by the English, and at Chinon, whence he was taken from the king's side and held prisoner at Montrésor. His grandson Louis II (1460-1525), commanded French troops in the conquest of Lombardy for Louis XII. Defeated and wounded fighting the Swiss at Novarra in 1513, he redeemed his reputation by raising the siege of Marseilles against the Constable de Bourbon's Imperial troops in 1523 before being killed at the Battle of Pavia in 1524. In 1485 he had wed the princesse du sang Gabrielle de Bourbon, daughter of Louis I, comte de Montpensier, subsequently marrying the daughter of Cesare Borgia. He inherited from his mother Marguerite d'Amboise, vicomtesse de Thouars, the title, "prince de Talmond", which Du Cange noted, in his Glossarium mediæ et infimæ latinitatis, had become attached to an allodial seigneurie in the Vendée. It was his grandson, François de La Trémoïlle (1505-1541), who succeeded Louis II in his titles, his father Charles, prince de Talmond (1486-1515), having been killed at the Battle of Marignano. He was taken prisoner at the battle of Pavia at which his grandfather was killed, but was subsequently ransomed. François wed the heiress Anne de Laval in 1521, who eventually brought to their descendants the pretendership to a royal throne. Their two younger sons, George (died 1584) and Claude (died 1566) founded, respectively, the branches of the marquis d'Royan (extinct 1698) and of the ducs de Noirmoutier (extinct 1733). The eldest son of François de La Trémoïlle, Louis III (1521-1577), was the first of his family to obtain ducal status when Charles IX conferred that honor upon him in 1563. His son with Jeanne de Montmorency, Claude (1566-1604), had the dukedom elevated into a peerage in 1595, although it was not registered as hereditary in the Parlement until 1599. He had converted to Protestantism and fought for the Huguenots during the French Wars of Religion at the battles of Coutras in 1587, Ivry in 1590 and Fontaine-Française in 1595, and at the sieges of Paris and Rouen. In 1598 he married Charlotte Brabantine of Orange-Nassau (1580-1631), daughter of the Protestant Dutch leader William the Silent. Claude's sister, Charlotte Catherine de La Trémoille (d. 1619), married Henri I de Bourbon, prince de Condé (1552-1588) in 1586, but when he died suddenly six months before the birth of their only son in September 1588, she was imprisoned on suspicion of
