Sicilian Expedition: What Happened

In 415 BC, Athens launched a massive military expedition to Sicily, aiming to conquer Syracuse, the most powerful Greek city on the island. The ambitious Alcibiades championed the plan, while the cautious general Nicias warned against it, but the assembly voted to send one of the largest forces ever assembled by a Greek city. Soon after the fleet sailed, Alcibiades was recalled to face charges of sacrilege. Instead, he fled to Sparta and advised the Spartans to send help to Syracuse. The Spartan general Gylippus arrived to lead the defense, and the Athenian siege stalled. Athens sent large reinforcements under Demosthenes in 413 BC, but a night attack failed, and the Athenian fleet was defeated and trapped in the Great Harbor of Syracuse. The army tried to escape overland and was destroyed. Nicias and Demosthenes were executed, and thousands of prisoners were put to work in the stone quarries of Syracuse, where many died. Athens lost around 200 ships and tens of thousands of men. It was the greatest disaster of the war and a turning point toward Athenian defeat.
