Greek Texts & Translations

Cerethrius was to be leader against the Thracians and the nation of the Triballi. The invaders of Paeonia were under the command of Brennus and Acichorius. Bolgius attacked the Macedonians and Illyrians, and engaged in a struggle with Ptolemy, king of the Macedonians at that time. It was this Ptolemy who, though he had taken refuge as a suppliant with Seleucus, the son of Antiochus, treacherously murdered him, and was surnamed Thunderbolt because of his recklessness. Ptolemy himself perished in the fighting, and the Macedonian losses were heavy. But once more the Celts lacked courage to advance against Greece, and so the second expedition returned home.

It was then that Brennus, both in public meetings and also in personal talks with individual Gallic officers, strongly urged a campaign against Greece, enlarging on the weakness of Greece at the time, on the wealth of the Greek states, and on the even greater wealth in sanctuaries, including votive offerings and coined silver and gold. So he induced the Gauls to march against Greece. Among the officers he chose to be his colleagues was Acichorius.

The muster of foot amounted to one hundred and fifty-two thousand, with twenty thousand four hundred horse. This was the number of horsemen in action at any one time, but the real number was sixty-one thousand two hundred. For to each horseman were attached two servants, who were themselves skilled riders and, like their masters, had a horse.

When the Gallic horsemen were engaged, the servants remained behind the ranks and proved useful in the following way. Should a horseman or his horse fall, the slave brought him a horse to mount; if the rider was killed, the slave mounted the horse in his master's place; if both rider and horse were killed, there was a mounted man ready. When a rider was wounded, one slave brought back to camp the wounded man, while the other took his vacant place in the ranks.

I believe that the Gauls in adopting these methods copied the Persian regiment of the Ten Thousand, who were called the Immortals. There was, however, this difference. The Persians used to wait until the battle was over before replacing casualties, while the Gauls kept reinforcing the horsemen to their full number during the height of the action. This organization is called in their native speech trimarcisia, for I would have you know that marca is the Celtic name for a horse.

This was the size of the army, and such was the intention of Brennus, when he attacked Greece. The spirit of the Greeks was utterly broken, but the extremity of their terror forced them to defend Greece. They realized that the struggle that faced them would not be one for liberty, as it was when they fought the Persian, and that giving water and earth would not bring them safety. They still remembered the fate of Macedonia, Thrace and Paeonia during the former incursion of the Gauls, and reports were coming in of enormities committed at that very time on the Thessalians. So every man, as well as every state, was convinced that they must either conquer or perish.

Herodotus ^note does not give the number of the Locrians under Mount Cnemis, but he does say that each of their cities sent a contingent. It is possible, however, to make an estimate of these also that comes very near to the truth. For not more than nine thousand Athenians marched to Marathon, even if we include those who were too old for active service and slaves; so the number of Locrian fighting men who marched to Thermopylae cannot have exceeded six thousand. So the whole army would amount to eleven thousand two hundred. But it is well known that not even these remained all the time guarding the pass; for if we except the Lacedaemonians, Thespians and Mycenaeans, the rest left the field before the conclusion of the fighting.
