Biron Charlesde Gontault
Biron, Charles de Gontault, Duc de, son of the above, was born in 1562. He served under his father at Arques, Ivry, Paris, and Rouen, was loaded with honours by Henry IV., who saved his life in the battle of Fontaine-Francaise, and was sent as ambassador to England. He seems to have lost his head through vanity, and, having entered into a conspiracy with Spain and Savoy to depose his master, was executed for treason in 1602. Several other members of the family were distinguished as soldiers or politicians in the two following centuries.
