Around late July, 469 BCE: Athenian triremes charge up the muddy Eurymedon River—Persian archers, caught off guard, scramble in panic.

Athens storms the riverbanks.
Late July, near the mouth of the Eurymedon—Cimon’s Athenian fleet surges forward, bronze rams slicing water. The Persians, expecting a siege, are instead forced into desperate open battle. The smell of smoke and mud mixes with Persian shouts and Greek war cries.
Persia routed twice—in a single day.
First, the Greeks smash the Persian fleet. Then, while the survivors stagger ashore, Cimon’s hoplites charge and crush the land army too. The double victory is total—Athenian dominance of the Aegean is sealed, for now.
A moment of Athenian swagger.
Ancient sources treat Eurymedon as a pivot: Athens, flush with triumph, begins to look not just eastward, but inward—at the power it now holds over its allies, and the temptations that come with it.
The victory at Eurymedon shattered Persian power in Asia Minor—Athens would never feel more confident, or more dangerous, than now.
