Battle of the Caecus River
# Battle of the Caecus River

The Battle of the Caecus River or Battle of the Kaikos was a battle between the Kingdom of Pergamon army commanded by Attalus I, and the Galatian tribes who resided in Anatolia. The battle took place near the source of the Caecus River (Ancient Greek: Κάϊκος, romanized: Káïkos) and resulted in a victory for the Kingdom of Pergamon.

The exact date of the battle is unknown, but it seems to have taken place early in the reign of Attalus I. Attalus I celebrated it as a great victory and as establishing his legitimacy as ruler early in his reign, and used it as a reason to dub himself Soter, Savior, and to take the title of basileus, king. R. E. Allen suggests that the early 230s (238 to 235 BCE) as the best guess of the date.

## Context

During the 3rd century BCE, there was a large migration of Gauls towards Anatolia. After passing through Greece, they arrived in Asia Minor, where they survived by raiding the towns along the Mediterranean coast. Many of these towns fell under the protection or direct control of the Kingdom of Pergamon, whose king, Eumenes I agreed to pay the Gauls tribute in return for their protection against the barbarians.

This situation changed with the ascendancy of Attalus I (believed to be the second cousin or the grandnephew of Eumenes I) in the year 241 BCE. Attalus I decided against continuing the payment of tribute to the Gauls. Attalus I was the first Pergamonese ruler who dared to go against this precedent. The stoppage of payment led to a military mobilization by both the Pergamese and the Galatians, eventually leading to war between the two parties. Attalus I's reign began in 241 BCE, giving the earliest possible date for this battle to have occurred.

## The battle

There are few surviving references that detail the course of this battle. What is known is that the outcome resulted in a decisive victory for Attalus I and Pergamon.

## Consequences

After the victory at the Caecus River, Attalus I adopted the surname "Sóter" (Greek: Savior) and officially received the title of King of Pergamon (basileus). The victory brought Attalus I fame, and he constructed monuments to his victory that were found by archaeologists centuries later. Even much later in his life, when he sent statues to Athens, he commissioned himself represented as in this battle.

One piece of interest was written by Pausanias. He recorded what was purportedly a prophecy of the sibyl Phaennis written a generation before the battle that predicted the battle states the following:

   Then verily, having crossed the narrow strait of the Hellespont, The devastating host of the Gauls shall pipe; and lawlessly They shall ravage Asia; and much worse shall God do To those who dwell by the shores of the sea For a short while. For right soon the son of Cronos Shall raise a helper, the dear son of a bull reared by Zeus Who on all the Gauls shall bring a day of destruction.

According to Pausanias, the "son of the bull", the "one with bull horns" is a poetic reference to Attalus I.

In recognition of this victory, a monument was erected at the acropolis of Pergamon that included the famous sculptures the Dying Gaul and the Ludovisi Gaul.

After the defeat, the Galatians continued to be a serious threat to the states of Asia Minor. The Pergamese and Galatians would fight again at the Battle of Aphrodisium. In fact, they continued to be a threat even after their defeat by Gnaeus Manlius Vulso in the Galatian War. From this point until the region's annexation by the Roman Republic, they were virtually ignored as they had no access to the sea.
