The Sicilian Expedition was an Athenian military campaign in Sicily from 415 to 413 BC during the Peloponnesian War. It pitted Athens and its allies against Syracuse, supported by Sparta and Corinth. The expedition ended in a devastating defeat for the Athenians and severely weakened their position in the war. The expedition was hampered from the outset by uncertainty over its objectives and command structure. Political manoeuvring in Athens expanded an originally modest force of twenty ships into a massive armada, while the expedition's principal advocate, Alcibiades, was recalled to Athens to stand trial before the fleet had even reached Sicily. Despite these setbacks, the Athenians achieved early successes. Syracuse, the most powerful state in Sicily, responded slowly to the threat and was nearly surrounded and besieged before the arrival of reinforcements under the Spartan general Gylippus, who galvanised the city's resistance. Thereafter, the Athenians gradually lost the initiative.
