Alanic Sarmatian influence in the 5th century

[Flavivs Aetivs]

Nobody in their right mind would place their most unreliable ally in the center. The Alans were placed in the center because, as the Strategikon notes, heavy cavalry lancers are the most effective for fighting the "Scythian" peoples (Huns and Avars).

There was no "pincer movement" either: The Goths completely routed and the Alans with possibly Thorismund and the Gothic cavalry attacked the Hunnic Center causing Attila's battle line to collapse and both armies simultaneously fell into disarray.

Remember, Jordanes was EXTREMELY biased against the Alans.
