This list represents the army of the kingdom of Pergamon in south-west Asia Minor from Eumenes I’s assumption of independence until the defeat of Aristonicus’ revolt after Attalos II bequeathed the kingdom to Rome, to whom the Pergamon had long been a stout ally. The mainly mercenary and light infantry army included cavalry who may still have been Hellenistic-type shieldless lancers, light horse with javelins and shield, Cretan archers and a large number of traditional light-armed peltasts. Citizen militia (possibly equipped as thureophoroi) served in garrisons, but were not relied on in field battles. Despite their reputation as the bulwark of Greece against the Galatians, they often hired Galatians, in 218 BC an entire tribe who were such a nuisance that they were dismissed. A few elderly ex-Seleucid elephants inherited in 189 BC quickly died out, but ex-Seleucid phalangites became a permanent part of the army. Reference: Armies of the Macedonian and Punic Wars D. Head.
