Megabazus, Darius the Great’s formidable field commander, secured Persia’s European flank with a mix of speed, logistics, and relentless pressure: he subdued Thrace, transplanted the Paeonians across the Hellespont to break their resistance, and compelled Macedon’s submission, turning the northern Aegean into a Persian glacis.
