Shapur II besieged the fortress city of Bezabde in Zabdicene in 360, held by the Romans.
Despite adamant resistance from three Roman legions and local archers, the Sasanians led by Shapur II successfully besieged and captured Bezabde. A battering-ram reportedly brought down one of the towers, through which the besiegers entered the city.
Later that year, Constantius II tried to retake Bezabde, but was unsuccessful.
