Today's Passage
This passage describes the Battle of Delium (424 BCE), a major engagement during the Peloponnesian War where Athenian forces under Hippocrates invaded Boeotia but suffered a devastating defeat.
Crawley Translation (1910)
Hippocrates had got half through the army with his exhortation, when the Boeotians, after a few more hasty words from Pagondas, struck up the paean, and came against them from the hill; the Athenians advancing to meet them, and closing at a run. The extreme wing of neither army came into action, one like the other being stopped by the water-courses in the way; the rest engaged with the utmost obstinacy, shield against shield. The Boeotian left, as far as the centre, was worsted by the Athenians. The Thespians in that part of the field suffered most severely. The troops alongside them having given way, they were surrounded in a narrow space and cut down fighting hand to hand; some of the Athenians also fell into confusion in surrounding the enemy and mistook and so killed each other. In this part of the field the Boeotians were beaten, and retreated upon the troops still fighting; but the right, where the Thebans were, got the better of the Athenians and shoved them further and further back, though gradually at first. It so happened also that Pagondas, seeing the distress of his left, had sent two squadrons of horse, where they could not be seen, round the hill, and their sudden appearance struck a panic into the victorious wing of the Athenians, who thought that it was another army coming against them. At length in both parts of the field, disturbed by this panic, and with their line broken by the advancing Thebans, the whole Athenian army took to flight. Some made for Delium and the sea, some for Oropus, others for Mount Parnes, or wherever they had hopes of safety, pursued and cut down by the Boeotians, and in particular by the cavalry, composed partly of Boeotians and partly of Locrians, who had come up just as the rout began. Night however coming on to interrupt the pursuit, the mass of the fugitives escaped more easily than they would otherwise have done. The next day the troops at Oropus and Delium returned home by sea, after leaving a garrison in the latter place, which they continued to hold notwithstanding the defeat.
Modern Translation
Hippocrates had managed to deliver his battle speech to only half his forces when the Boeotians, after Pagondas gave them a few final words of encouragement, raised their battle cry and charged down from the hill. The Athenians advanced to meet them, both armies breaking into a run as they closed the distance. Neither army's extreme flanks engaged in combat, as streams blocked their advance on both sides. The main forces, however, collided with fierce determination, shield pressed hard against shield. The Boeotian left wing, extending to their center, was overwhelmed by the Athenians. The Thespians suffered the heaviest casualties in this sector. When the troops beside them retreated, the Thespians found themselves encircled in a confined area and were slaughtered in close combat. In the chaos of encirclement, some Athenians became disoriented and accidentally killed their own comrades. While the Boeotians were losing ground on this flank and falling back toward their still-fighting units, their right wing, where the Thebans were positioned, gained the upper hand against the Athenians, steadily pushing them back, though the advance was initially gradual. At this critical moment, Pagondas, observing his left wing's predicament, dispatched two cavalry squadrons around the hill under cover. Their unexpected emergence terrified the previously victorious Athenian wing, who believed a fresh army was attacking them. Eventually, panic spread through both sections of the battlefield, and with the Thebans continuing their relentless advance, the Athenian line shattered completely. The entire Athenian army fled in disorder. Some ran toward Delium and the coast, others toward Oropus, still others toward Mount Parnes—each soldier fleeing wherever he thought safety lay. The Boeotians pursued relentlessly, cutting down the fugitives, with their cavalry—reinforced by Locrian horsemen who arrived just as the rout began—proving particularly deadly. Fortunately for the Athenians, nightfall interrupted the pursuit, allowing most of the fleeing soldiers to escape what would have been certain death. The following day, the Athenian forces at Oropus and Delium sailed home, though they maintained a garrison at Delium despite their defeat.
Historical Context
This passage describes the Battle of Delium (424 BCE), a major engagement during the Peloponnesian War where Athenian forces under Hippocrates invaded Boeotia but suffered a devastating defeat. The battle marked the first time in Greek warfare that tactical reserves were effectively used, as Pagondas's hidden cavalry turned the tide of battle. The Athenian defeat had significant strategic implications, ending their ambitious plan to control Boeotia and demonstrating the effectiveness of Theban military innovations. The battle featured approximately 7,000 Athenian hoplites against a similar number of Boeotians, with the Thebans fielding an unusually deep phalanx of 25 ranks. This defeat, coming shortly after setbacks in Thrace, marked the beginning of a difficult period for Athens and showed that their land forces could be decisively beaten by well-led Greek opponents.
Key Themes
Annotations & References
Hoplite Warfare
The battle exemplifies classical Greek hoplite combat, with its emphasis on maintaining formation ('shield against shield') and the catastrophic consequences when a phalanx broke. The deeper Theban formation of 25 ranks proved decisive against the standard 8-rank Athenian deployment.

This 424 BCE battle was notable for several military innovations, including the first recorded use of tactical reserves in Greek warfare and possibly the first use of field artillery. The Boeotian victory ended Athenian expansion into central Greece.

The confusion leading to Athenians killing each other highlights a common problem in ancient battles. Without uniforms and in the dust and chaos of close combat, distinguishing friend from foe was extremely difficult, especially when units became intermixed.
