Battle of Dara
The setting
Dara (Daras), Roman-Persian frontier in northern Mesopotamia (near modern Oguz / Nusaybin on the Turkey-Syria border, approx. 37.18 N, 40.95 E)
The open, gently rolling plain immediately south of the Roman fortress city of Dara - flat cavalry ground that favored the larger Persian horse, which Belisarius deliberately reshaped by digging a wide, angled system of ditches in front of his line to break up and channel any charge.

Recorded resultdecisive victory
Decisive Eastern Roman victory. Fighting on the tactical defensive against a larger army, Belisarius broke two successive Persian wings by counter-charging his hidden and flanking cavalry, then rolled up the Persian center; the Sassanid army was driven from the field.
How the atlas explains it
Belisarius refused to meet a bigger cavalry army on open ground on its own terms. In front of his line he had his men dig an interlocking system of ditches - a long central trench with forward-angled arms at the flanks - that channeled, slowed, and blunted the Persian horse exactly where he wanted them. He anchored his wings, hid detachments of Hunnic horse to strike the flanks, and held the tactical defensive until the Persians committed. When their left and then their right pressed the attack, his allied and household cavalry (the bucellarii) counter-charged into the disordered attackers and enveloped them, cutting the elite Immortals off and collapsing the wings inward. It is a textbook marriage of field fortification, combined arms, and counter-envelopment - engineering and discipline substituting for numbers.
What followed
Dara was Belisarius's breakout victory and one of the few clear field wins the Romans scored over Sassanid Persia in the Iberian War. It made his reputation, marking him as the outstanding general of the age and putting him on the path to command Justinian's reconquest of the West a few years later. Strategically it stabilized the eastern frontier long enough for Justinian to turn his armies toward North Africa and Italy - the same overreach that would ultimately exhaust the empire.
