Bernard de la Salle, was a French mercenary captain during the Hundred Years War.
On Monday 18 November 1359 he climbed the castle of Clermont-en-Beauvaisis with steel grabs.
However, after the Treaty of Brétigny (1360) He and his men found themselves unemployed and so become one of the 30 or so, so-called Tard-Venus bandits.
In 1369, along with Bernard de Wisk and Hortingo de la Salle, he captured Belleperche Castle, where Isabella of Valois, Duchess of Bourbon lived.
The Duke of Bourbon was her son, and Frossart tells us that the siege redoubt he organized was "as strong and as well fortified as a good town might have been".
