The battle of Pedasus or Pedasa in 497 or
496 was the third in a series of battles between the Persians and Carian rebels
during the Ionian Revolt, and was a major Persian defeat that effectively ended
their first large scale counterattack against the rebels. The Ionian Revolt
broke out in 499, but it didn't spread to Caria until 498, in the aftermath of
the Ionian raid on Sardis (498). In 497 the Persians launched their first major
counterattack against the rebels, commanded by three son-in-laws of Darius I.
One of those generals, Daurises, led his army to the Hellespont, where he
captured Dardanus, Abydus, Percote, Lampsacus and Paesus.
Ionian Revolt, 499-493
He was forced to abandon this successful campaign when news reached him of the
Carian revolt. He turned south and headed towards the Carian border. This news
soon reached the rebels, who decided to make a stand on the River Maeander. The
resulting battle of the Maeander in 497 was a major Persian victory. The Carian
survivors retreated south to the sanctuary of Zeus the God of War at Labraunda,
where they were debating whether they should surrender or flee from Anatolia
when they received reinforcements from Miletus. This restored their morale, and
they decided to stand and fight. The Persians attacked, and inflicted a second
heavy defeat on them, possibly at Labraunda in 497. After this second victory,
there appears to have been a pause in the campaigning. Both battles were
described as hard fought, so the Persians may have needed time to regroup. The
Carians had suffered two heavy defeats, and were in even more need of a rest.
Unfortunately we don't know how long the pause was. All we know from Herodotus
is that the next battle took place 'Some time after this disaster', when both
sides had had time to regroup. This probably places the battle of Pedasa early
in 496, the next campaigning season, but it may have been fought later in 497.
The campaign was renewed when the Persians decided to attack the Carian cities.
The Carians, commanded by Heraclides, son of Ibanollis, from Mylasa, set up an
ambush at Pedasa (or Pedasus), in the south-west of Caria (just to the south of
Mylasa). The Persians fell into the trap during a night march, and their army
was almost wiped out. Amongst the dead were Daurises himself, along with
Amorges, Sisimaces and Myrsus son of Gyges. This disaster effectively ended the
first Persian counterattack. The Persians had already lost Hymaees, the second
of their three commanders, who died of illness while campaigning around Ilium.
With two commanders and one of their armies lost, they were forced to pause,
and didn't return to the offensive until 494.
