Siege of Pirisabora

The Siege of Pirisabora took place when the Roman Emperor Julian besieged the city of Pirisabora in April 363. After settling political affairs in Constantinople, Emperor Julian gathered an army of 95,000 in Antioch for his invasion of the Sassanid Empire. Upon his arrival at Carrhae, Julian sent his generals, Procopius and Sebastian, with 30,000 men into Armenia to join up with King Tiran's army of 24,000.

Meanwhile, Julian marched his army to Pirisbora, placing the city under siege. After two days, the city fell. Julian distributed spoils to his troops and had the city burned. Following this victory, the Roman army marched towards Ctesiphon, sacking and burning Bithra, Diacira and Ozogardana in the process.
