 Licinius encamped his army in a strong position near Adrianople (Hadrianopolis), the major city of inland Thrace.Constantine advanced eastward from Thessalonica until he came to the Hebrus River, on which Adrianople stands, and set up his own camp.Licinius arranged his defensive line, of 200 stades in length, in a strong position between a height overlooking the town and the confluence of the Hebrus with a tributary.
