In June of year 363 AD, near the city of Samarra in modern day Iraq, a large professional Roman army was in a state of total chaos. The Romans were led by Princeps Julian, a cultured and competent leader who had led the army to victory near the Persian capital of Ctesiphon a month earlier. Julian however failed to capitalize on this important tactical victory, and did not siege the city as an incoming force led by the King of Kings Shapur II was closing in from the east. Near Samarra, Julian’s army of 35,000 was intercepted by skirmishing cavalry sent by Shapur. The Persians attacked the roman cohorts who were advancing in square formations to avoid encirclement. Julian, seeing his troops panicking in front of the sudden Sassanid attack, rushed forward without his armor in order to encourage his men to fight on. He was however spotted by Sassanid officers who sent an arab regiment of auxiliary cavalry to assassinate him. Julian was hit on his back by a javelin and was immediately rushed to the rearguard. His doctor Oribasius couldn’t do anything, as the Emperor died a few hours later in his tent. The roman army, now without a leader, chose Jovian (Julian’s Comes Domesticorum) as the new emperor. Facing continuous raids from the Sassanids, the Romans were forced to sign a humiliating peace treaty with Shapur II. Shortly after the peace negotiations, emperor Jovian died in his tent in Anatolia (Dadastana) under mysterious circumstances.
