Factual error: Aetius' troops don't look anything like 5th century Roman soldiers. They are carrying a large rectangular shield, a pilum (a spear which was used for throwing) and a sword (gladius) on their right. This was typical for the Roman army until about the 3rd century A.D. In Aetius' time, the soldiers would have had smaller oval shields, a hasta (a lance used for stabbing and for fending off cavalry attacks) and a sword (spatha) on their left. Also, there would be an enormous amount of "barbarian" mercenaries in the Roman army (Goths, Vandals, even Huns.), so it was hardly a Roman army anymore. And where's Aetius' cavalry?

Factual error: The Roman emperor Valentinian III did not kill Flavius Aetius after his victory over Attila. He killed the general one year after Attila's death, in 454 A.D.

Factual error: Galla Placidia, the emperor Valentinian's mother, could never have witnessed her son murdering Flavius Aetius. Placidia died in 450 AD, Aetius four years later.
