[6] The Mirranes of Persia advanced, with forty thousand of her best troops, to raze the fortifications of Dara; and signified the day and the hour on which the citizens should prepare a bath for his refreshment, after the toils of victory.

He encountered an adversary equal to himself, by the new title of General of the East; his superior in the science of war, but much inferior in the number and quality of his troops, which amounted only to twenty-five thousand Romans and strangers, relaxed in their discipline, and humbled by recent disasters.

As the level plain of Dara refused all shelter to stratagem and ambush, Belisarius protected his front with a deep trench, which was prolonged at first in perpendicular, and afterwards in parallel, lines, to cover the wings of cavalry advantageously posted to command the flanks and rear of the enemy.

When the Roman centre was shaken, their well-timed and rapid charge decided the conflict: the standard of Persia fell; the immortals fled; the infantry threw away their bucklers, and eight thousand of the vanquished were left on the field of battle.

In the next campaign, Syria was invaded on the side of the desert; and Belisarius, with twenty thousand men, hastened from Dara to the relief of the province.
