Its right wing rested on the Enipeus, its left was spread out on the plain.

Pompey himself commanded the left with the two legions the Senate had taken from Caesar.

Outside him on the plain were his allies covered by the cavalry.

Opposite Pompey was Caesar, with the famous Tenth Legion.
His left and centre were led by his faithful Tribunes, Mark Antony and Cassius Longinus.
At the given signal Caesar's front ranks advanced on a run, threw their darts, drew their swords, and closed in.

At once Pompey's cavalry charged, outflanking the enemy's right wing, and driving back the opposing cavalry, who were inferior in numbers.
