Just as the Republican cavalry were victorious, three of Octavius' legions started to waver. He tried to shore up the centre by intervening personally, and was carried off into the distance as his legions gave way completely. Just as with the other side of the Via Egnatia, this was a historical result - the initial impetus gave Brutus' legions the edge over the hated Octavius.
Next up: the grand finale. Brutus meets Antonius, when I get around to posting it.
