At that time it happened that Johannizza, the King of Wallachia and Bulgaria, with all his host, marched against the marquis, towards a city called Seres. And the marquis had set a strong garrison of his people in the city, for he had set there Hugh of Colemi, who was a very good knight, and hi,h in rank, and William of Arles, who was his marshal, and great part of his best men. And Johannizza, the King of Wallachia besieged them; nor had he been there long before he took the burgh by force.
