The biggest battle of Roman

[Flavivs Aetivs]

I've noticed Ancient Authors tend to just add a "0" to the end of the size of an army. But there could be other reasons for this as well: the strategicon reports the difficulties of scouting and determining the size of an enemy force, especially by an inexperienced scout, and tells how to make an army appear larger than it actually is. He even states that "Scythian" (Hun/Avar) armies are the most difficult as their units are not regularly organized, they usually disperse their armies over a wide distance, etc. etc.

For example, Aetius' army of 60,000 in 425, for example, may have been reported as 60,000 men, but was in reality far less. The Huns of the Tisza couldn't field more than about 10,000 men.
