Thracian warfare In the 4th century BC, both infantry and cavalry troops started wearing helmets (some of leather) and some peltasts are seen with greaves. Principal weapons in the 4th century BC (as well as earlier) were the spear and short knife. Armor, when it was available (for the nobility), was at first leather or bronze but iron armour started appearing in the 4th century BC. Thracian cavalry would wear leather armor or no armor and would be armed with javelins, a bow, or a spear. Only royal cavalry would wear armor. Oval shields and peltes (even by heavy cavalry) were later
Battle of Gela (405 BC) while smaller ones like Himera and Messana mustered between 3,000–6,000 soldiers. Gela probably could field similar numbers. Dionysius brought 30,000 foot and 1,000 horsemen, recruited from Syracuse, allied Sicilian Greek cities, and mercenaries along with 50 triremes to Gela in 405. The mainstay of the Greek army was the hoplite, drawn mainly from the citizens by Dionysius, and had a large number of mercenaries from Italy and Greece as well. Sicels and other native Sicilians also served in the army as hoplites and also supplied peltasts, and a number of Campanians, probably equipped like Samnite or Etruscan warriors, were present
