Instead of immediately attacking with the legionaries, Ventidius made use of his slingers to rain down projectiles on the Parthian heavy cavalry, which included Pacorus himself. After the barrage was lifted the legionaries moved in and were quickly able to identify Pacorus because of his standard and expensive armor. Pacorus was eventually slain along with his bodyguards, and the remaining cavalry broke and attempted to flee from their entrapment, which not all managed to do. Overall the Roman army had achieved a complete victory. Pacorus' father Orodes II, overwhelmed by grief, then chose his oldest surviving son, Phraates IV, as his successor.
