Bertrand VI (c. 1417 - 26 September 1497) was lord of La Tour and count of Auvergne from 1461until his death. He was also count of Boulogne from 1461 to 1477, when he exchanged that title for the county of Lauragais, which he held for the remainder of his life.
Bertrand was part of Charles VII of France's entourage from 1441 to 1451,[1] during the last stages of the Hundred Years' War.[2] He took part in the Siege of Tartas, in 1442, where he is cited as lord of Montgascon. He was proclaimed knight after the 1450 Battle of Formigny.
In 1461, his father, Bertrand V of La Tour, died. Bertrand succeeded him as his only heir.
In 1468, during the Burgundian Wars, he occupied savoyard Bresse, following Louis XI's orders.
In 1473, Bertrand built the franciscan church of Vic-le-Comte.
In 1477, Charles the Bold died. This allowed Louis XI to reconquer the county of Boulogne, which had been occupied by burgundian forces. Louis then handed it back to Bertrand. However, during the same year, Bertrand II dealt with Louis XI, exchanging the county of Boulogne with the county of Lauragais. Boulogne, so became part of the royal domain.[3] [4]
Bertrand died in 1497 and was succeeded by his first-born son: John IV, Count of Auvergne.
In 1445, Bertrand married Louise de La Trémoille, daughter of Georges de La Trémoille and Catherine de L'Isle-Bouchard.[5] They had five children:
