The couple married on 20 April 1770 at the Palace of Versailles in front of the court. Bathilde was nineteen and her husband was fourteen. Due to the age of the groom the marriage was not consummated and Bathilde returned to her convent. Before long, her husband had carried her off from the convent. After only six months he began to tire of marriage and turned his attention to other women. The periodic reconciliations between Bathilde and her husband eventually allowed her to give birth to their only son, Louis Antoine Henri de Bourbon, in August 1772. From marriage until the birth of her son, she was known as the Duchess of Enghien; after the birth she was known as the Duchess of Bourbon.
