Boniface sent Agnes to Abydos, Hellespont, Mysia through a galley. His messengers then reached Henry with information to her location. Geoffrey Villehardouin himself and Miles of Brabant were assigned to escort her. Villehardouin describes Agnes as "very good and fair". Agnes was escorted to Constantinople with no mentioned incident. On 4 February 1207, Agness married Henry of Flanders. According to Villehardouin, the marriage took place in Hagia Sophia, Constantinople on the Sunday following Candemass. The wedding feast took place in Boukoleon Palace. According to the "Dictionnaire historique et Généalogique des grandes familles de Grèce, d'Albanie et de Constantinople" (1983) by Mihail-Dimitri Sturdza, the marriage was part of a new alliance between Boniface and Henry against Kaloyan of Bulgaria.
