Most of the decade following the first offensive Greek campaigns against Xerxes’ forces are lost to us. There are hints at great battles and rapid Athenian expansion, but almost nothing is certain until the Battle of the Eurymedon. In the mid-460s BCE, the Persian fleet had recovered enough to stage a renewed offensive, but the Athenian general Kimon had advanced warning. He commanded a fleet from Athens’ Delian League and made a preemptive strike in southern Anatolia, where he destroyed the fleet and routed the Persian army. This battle at the mouth of the Eurymedon River once again changed the direction of Persia’s war with Athens, effectively kicking Persian military power out of the Aegean for decades to come.
