Today's Passage
This passage describes two simultaneous military setbacks in 425 BCE during the Peloponnesian War.
Crawley Translation (1910)
As soon as the Peloponnesians in Attica heard of the occupation of Pylos, they hurried back home; the Lacedaemonians and their king Agis thinking that the matter touched them nearly. Besides having made their invasion early in the season, and while the corn was still green, most of their troops were short of provisions: the weather also was unusually bad for the time of year, and greatly distressed their army. Many reasons thus combined to hasten their departure and to make this invasion a very short one; indeed they only stayed fifteen days in Attica.
About the same time the Athenian general Simonides getting together a few Athenians from the garrisons, and a number of the allies in those parts, took Eion in Thrace, a Mendaean colony and hostile to Athens, by treachery, but had no sooner done so than the Chalcidians and Bottiaeans came up and beat him out of it, with the loss of many of his soldiers.
Modern Translation
When the Peloponnesians campaigning in Attica learned that Pylos had been seized, they immediately withdrew homeward. The Spartans and their king Agis regarded this development as a direct threat to their interests. Moreover, they had launched their invasion unusually early in the season while the grain was still unripe, leaving most of their forces short of supplies. The weather proved exceptionally harsh for that time of year, causing considerable hardship to their troops. These multiple factors combined to accelerate their withdrawal and resulted in an unusually brief campaign—they remained in Attica for merely fifteen days.
During this same period, the Athenian commander Simonides assembled a modest force of Athenians from local garrisons along with various allied contingents from the region. He successfully captured Eion in Thrace, a colony of Mende that was hostile to Athens, through an act of betrayal. However, his victory proved short-lived: the Chalcidians and Bottiaeans promptly counterattacked and expelled him from the city, inflicting heavy casualties on his forces.
Historical Context
This passage describes two simultaneous military setbacks in 425 BCE during the Peloponnesian War. The main event is the Spartan withdrawal from their annual invasion of Attica upon hearing that Athenian forces under Demosthenes had fortified Pylos in Messenia, dangerously close to Spartan territory. This occupation threatened to provide a base for helot revolts and raids into Laconia. King Agis II led the Spartan forces, but multiple factors—early timing, supply shortages, and bad weather—combined with the Pylos crisis to make this one of the shortest Spartan invasions of the war. Meanwhile, in northern Greece, the Athenian general Simonides briefly captured Eion through treachery but was quickly expelled by local Chalcidian and Bottiaean forces, demonstrating Athens' ongoing difficulties in maintaining control over the volatile Thracian region despite their imperial ambitions.
Key Themes
Annotations & References
Pylos Campaign
The fortification of Pylos by Demosthenes was a masterstroke of Athenian strategy, establishing a permanent base in Messenia that could encourage helot revolts and threaten Sparta's agricultural heartland. This forced Sparta to divert resources from offensive operations to homeland defense.

The annual Spartan invasions of Attica were a key element of their strategy to force Athens to surrender by devastating its countryside. However, Athens' Long Walls allowed the population to shelter within the city while maintaining access to supplies via their naval supremacy.
Learn more →Chalcidice
The Chalcidian peninsula in northern Greece was strategically vital for its resources and position. The region's cities frequently switched sides during the war, and Athenian control was constantly challenged by local resistance and Spartan influence.

Military campaigns in ancient Greece were heavily constrained by logistics. Armies typically campaigned during summer when crops could be destroyed and foraged. The early timing of this invasion left the Spartans without adequate supplies, demonstrating these logistical realities.
