=== By place ===

==== Greece ====
* After their victory in the [[Battle of Arginusae]] over the [[Sparta]]ns, the [[Athens|Athenian]] fleet follows the [[Apportionment (politics)|reappointed]] Spartan admiral, [[Lysander]], to the [[Hellespont]]. The Athenian fleet under Admiral [[Conon]] is destroyed by the Spartans under Lysander in the [[Battle of Aegospotami]] in the [[Sea of Marmara]] and Conon flees to [[Cyprus]].
* The Spartan king [[Pausanias of Sparta|Pausanias]] lays siege to Athens while Lysander's fleet blockades [[Piraeus]]. This action closes the grain route through the Hellespont, thereby starving Athens.
* While the [[Peloponnesia]]ns besiege Athens, [[Theramenes]] tries to negotiate with Lysander. He is away for three months while Athens is being reduced to starvation. Then he heads the embassy that negotiates the terms of [[Capitulation (surrender)|capitulation]] to the Spartans.

==== Sicily ====
* [[Dionysius the Elder]] rises to power as the tyrant of [[Syracuse, Sicily|Syracuse]]. He makes peace with the [[Carthage|Carthaginian]] general, [[Himilco (general)|Himilco]] (whose army has been weakened by the plague), and fortifies Syracuse. This treaty leaves Carthage in control of most of Sicily.
* Dionysius the Elder ruthlessly consolidates and expands his power. He builds a wall around Syracuse and fortifies Epipolae. The [[Ancient Greece|Greek]] citizens of [[Naxos (Sicily)|Naxos]], [[Catana]], and [[Leontini]] are removed from their cities; many of them are enslaved and their homes are given to Sicilian and [[Italy|Italian]] [[mercenaries]]. Dionysius prepares his army to fight against Carthage, which now occupies western and southern Sicily.
