Potidaea fell in 356 and Methone, the last Athenian stronghold, in 353.
So at length Potidaea was strongly invested on either side, and from the sea by the ships co-operating in the blockade.
It was followed by a second, which ordered Athens to raise the siege of Potidaea, and to respect the independence of Aegina.
Send an army into Attica, and compel the Athenians to withdraw their forces from Potidaea.
Full ten thousand heavy infantry were in the field, all Athenian citizens, besides the three thousand before Potidaea.
