This passage describes the critical moment before the Battle of Sphacteria (425 BCE), a pivotal engagement in the Peloponnesian War.
Crawley Translation (1910)
After he had settled everything in the assembly, and the Athenians had voted him the command of the expedition, he chose as his colleague Demosthenes, one of the generals at Pylos, and pushed forward the preparations for his voyage. His choice fell upon Demosthenes because he heard that he was contemplating a descent on the island; the soldiers distressed by the difficulties of the position, and rather besieged than besiegers, being eager to fight it out, while the firing of the island had increased the confidence of the general. He had been at first afraid, because the island having never been inhabited was almost entirely covered with wood and without paths, thinking this to be in the enemy’s favour, as he might land with a large force, and yet might suffer loss by an attack from an unseen position. The mistakes and forces of the enemy the wood would in a great measure conceal from him, while every blunder of his own troops would be at once detected, and they would be thus able to fall upon him unexpectedly just where they pleased, the attack being always in their power. If, on the other hand, he should force them to engage in the thicket, the smaller number who knew the country would, he thought, have the advantage over the larger who were ignorant of it, while his own army might be cut off imperceptibly, in spite of its numbers, as the men would not be able to see where to succour each other.
The Aetolian disaster, which had been mainly caused by the wood, had not a little to do with these reflections. Meanwhile, one of the soldiers who were compelled by want of room to land on the extremities of the island and take their dinners, with outposts fixed to prevent a surprise, set fire to a little of the wood without meaning to do so; and as it came on to blow soon afterwards, almost the whole was consumed before they were aware of it. Demosthenes was now able for the first time to see how numerous the Lacedaemonians really were, having up to this moment been under the impression that they took in provisions for a smaller number; he also saw that the Athenians thought success important and were anxious about it, and that it was now easier to land on the island, and accordingly got ready for the attempt, sent for troops from the allies in the neighbourhood, and pushed forward his other preparations. At this moment Cleon arrived at Pylos with the troops which he had asked for, having sent on word to say that he was coming. The first step taken by the two generals after their meeting was to send a herald to the camp on the mainland, to ask if they were disposed to avoid all risk and to order the men on the island to surrender themselves and their arms, to be kept in gentle custody until some general convention should be concluded.
Modern Translation
After securing the assembly's approval and receiving the Athenians' vote to command the expedition, he selected Demosthenes—one of the generals stationed at Pylos—as his colleague and hastened his preparations for departure. He chose Demosthenes specifically because he had learned that the general was already planning an assault on the island. The soldiers, suffering under harsh conditions and feeling more like the besieged than besiegers, were eager for decisive action. Moreover, the recent burning of the island had bolstered the general's confidence. Initially, Demosthenes had harbored concerns because the island, never having been settled, was almost completely forested and lacked paths. He believed this gave the enemy an advantage: they could land a substantial force yet remain vulnerable to attacks from concealed positions. The dense woods would hide the enemy's mistakes and troop strength from him, while every error his own forces made would be immediately visible, allowing the Spartans to strike unexpectedly wherever they chose, maintaining the initiative. Furthermore, if he forced an engagement in the forest, he reasoned that the smaller force familiar with the terrain would hold the advantage over his larger but unfamiliar army. His numerous troops might be gradually destroyed without realizing it, unable to see where to support one another.
These concerns were significantly influenced by the Aetolian catastrophe, where the forest had played a crucial role in the defeat. However, circumstances changed when some soldiers, forced by space constraints to land on the island's edges for their meals while maintaining guard posts against surprise attacks, accidentally started a small fire. When the wind picked up shortly after, nearly the entire forest burned before anyone realized what was happening. For the first time, Demosthenes could accurately assess the true number of Lacedaemonians, having previously believed they were provisioning fewer men. He also recognized that the Athenians considered success vital and were deeply concerned about the outcome. With landing on the island now more feasible, he prepared for the assault, summoning troops from nearby allies and advancing his other preparations. At this juncture, Cleon arrived at Pylos with the forces he had requested, having sent advance notice of his coming. The two generals' first joint action was to dispatch a herald to the mainland camp, inquiring whether they might avoid unnecessary risk by ordering the island's defenders to surrender themselves and their weapons, to be held under humane conditions until a comprehensive agreement could be reached.
Historical Context
This passage describes the critical moment before the Battle of Sphacteria (425 BCE), a pivotal engagement in the Peloponnesian War. Cleon, the Athenian demagogue who had boldly promised to capture or kill the Spartans trapped on the island within twenty days, arrives at Pylos to join Demosthenes. The accidental burning of the island's forest—which had previously provided cover for the Spartan hoplites—dramatically altered the tactical situation. The passage reveals the careful military planning behind what would become one of Athens' most shocking victories: the capture of 292 Spartan soldiers, including 120 Spartiates (full Spartan citizens). This unprecedented surrender of Spartan hoplites would provide Athens with valuable hostages and shatter the myth of Spartan invincibility, fundamentally altering the war's dynamics and demonstrating that aggressive democratic leadership could achieve what traditional aristocratic generals had failed to accomplish.
Key Themes
Annotations & References
The Pylos Campaign
The Pylos-Sphacteria campaign represented a major strategic innovation in Greek warfare. By establishing a permanent fort in enemy territory at Pylos, Athens created a base for helot desertion and forced Sparta into an disadvantageous position, ultimately trapping their best troops on Sphacteria island.

Cleon exemplified the new breed of Athenian politician: a wealthy tanner rather than an aristocrat, he used aggressive rhetoric and populist appeals to dominate the assembly. His success at Sphacteria, despite lacking military experience, validated his political approach and strengthened radical democracy.

The accidental forest fire illustrates how environmental factors could decisively influence ancient battles. Greek hoplite warfare typically favored open terrain; forests neutralized the phalanx formation and numerical superiority, as Demosthenes learned painfully in Aetolia.
Learn more →The Aetolian Disaster
In 426 BCE, Demosthenes led an overconfident Athenian force into Aetolia's forests, where light-armed locals destroyed his hoplites. This traumatic defeat, which Thucydides references here, taught Demosthenes valuable lessons about terrain and unconventional warfare that he would apply at Sphacteria.
