Tactically, Phillip absorbed the lessons of centuries of warfare in Greece. He echoed the tactics of Epaminondas at Chaeronea, by not engaging his right wing against the Thebans until his left wing had routed the Athenians; thus in course outnumbering and outflanking the Thebans, and securing victory. Alexander's fame is in no small part due to his success as a battlefield tactician; the unorthodox gambits he used at the battles of Issus and Gaugamela were unlike anything seen in Ancient Greece before.
