Peltast fighting used by peltasts originated in Thrace and the first Greek peltasts were recruited from the Greek cities of the Thracian coast. They are generally depicted on vases and in other images as wearing the typical Thracian costume, which includes the distinctive Phrygian cap made of fox-skin and with ear flaps. They also usually wear a patterned tunic, fawnskin boots and a long cloak, called a zeira, decorated with a bright, geometric, pattern. However, many mercenary peltasts were probably recruited in Greece. Some vases have also been found showing hoplites (men wearing Corinthian helmets, greaves and cuirasses, holding hoplite spears)
Battle of Delium made use of planned tactical warfare for one of the first times in recorded history. In the previous centuries, battles between Greek city states were relatively simple encounters between massed formations of hoplites, where cavalry played no important role and all depended on the unity and force of the massed ranks of the infantry, straining against the opponent. At Delium, Pagondas made use of deeper ranks, reserves, cavalry interventions, light-armed skirmishers (peltasts) and gradual changes in tactics during the battle. These novelties were to be later exploited in more famous Theban victories in the following century, led by Epaminondas in
