How Peloponnesian War's dead compare to other conflicts and events.
120 dead
Of the 420 Spartiates trapped on Sphacteria, 292 survived to surrender. Of those, 120 were full Spartiates — a significant fraction of Sparta's total citizen body, which had been declining for generations. The capture shattered the myth that Spartans would always die rather than surrender.
30,000 dead
The Plague of Athens (430–426 BC) killed an estimated 25–33% of Athens's population — perhaps 30,000–75,000 people. These deaths are not included in military casualties but were the single largest cause of Athenian wartime losses and arguably the war's most decisive event.
40,000 dead
The Sicilian Expedition losses (415–413 BC) are the single largest military disaster in Athenian history. Thucydides writes that the expedition 'was alike calamitous in every respect; for the suffering that fell upon the Athenians was the greatest that had ever happened to any Greek state.'
