How a ragtag group of exiles toppled the brutal regime of the Thirty Tyrants
In 404 BC, a small band of Athenian exiles seized a hill in Piraeus, defying a massive Spartan-backed army. Despite being vastly outnumbered, their tactical charge down the Munychia hill shattered the oligarchic forces, killed their leader, and ultimately paved the way for the restoration of Athenian democracy.
The conflict began when Athenian exiles, led by Thrasybulus, established a stronghold at Phyle in late 404 BC. After successfully repelling an initial attempt to dislodge them, their numbers grew to 1,000 men. Seeking a more strategic position, they marched by night to Piraeus and occupied the Munychia, a prominent hill overlooking the port. The ruling Thirty Tyrants, supported by a Spartan garrison, responded by marching out the next morning to crush the uprising.
The tactical disparity was stark. The exiles formed a line ten ranks deep at the summit, bolstered by light troops and spear throwers. In contrast, the joint Spartan-oligarchic force assembled in the market below with a massive formation fifty ranks deep. Despite this overwhelming depth, the oligarchs were vulnerable. Thrasybulus exploited this by reminding his men that they had already routed the Spartan right wing in a previous skirmish, while the left wing consisted of the very men who had exiled them.
As the oligarchic forces advanced up the road, the exiles launched a decisive charge downhill. The momentum broke the enemy line, turning the engagement into a rout. Seventy members of the oligarchic force were killed, including the leader of the Thirty, Critias, and another prominent figure, Charmides. This defeat proved fatal to the regime's authority. The following day, the council of three thousand deposed the Thirty, who fled to Eleusis. While a new board of ten attempted to hold power, the shift in momentum eventually led to a Spartan-mediated settlement under Pausanias, effectively ending the tyranny and restoring democratic governance to Athens.
