This list covers the branch of the Celts who went east through the Danubian plains and invaded Greece, causing many upsets before they settled down in central Asia Minor. Pausanias, Justin & Diodorus quote large numbers of both foot and cavalrymen. Some light Celtic chariots initially used were supplemented in 273 BC by captured Seleucid scythed chariots. Galatian foot fought naked in dense bodies, displaying fanatic fervour and indifference to wounds and destroyed several pike armies, but could not cope with skirmishers in difficult terrain or on one occasion with elephants. Their few skirmishers usually supported the cavalry. Fanaticism waned after they were stopped by Pergamon 241-228 BC, but they still fought naked against the Romans in 189 BC. Thessalian and Aenianian nobles joined the invasion of Greece in 279 BC and Pisidian allied contingents assisted in Asia Minor. The tetrarch Diotarus was made king of Galatia by Pompey’s settlement of the east and sent troops to aid Roman armies in 50-51 BC and 47 BC. References: Armies of the Macedonian and Punic Wars D.
