GUEBRIANT, JEAN BAPTISTE BUDES, COMTE DE (1602-1643), marshal of France, was born near St. Brieuc on Sept. 2, 1602 of an old Breton family. In the Thirty Years' War he commanded (1638-39) the French contingent in the army of Bernard of Saxe-Weimar. Upon the death of Bernard he received the command of his army, and tried, in conjunction with J. Baner (IS96-1641), the Swedish general, a bold attack upon Regensburg (164o) . His victories of Wolfenbiittel (1641) and Kempen (1642) won for him the marshal's baton. He was mortally wounded at Rottweil on Nov. 17, See A.
