In 371 BCE, the Theban General Epaminondas did battle with Sparta at the height of its power. Sparta, having won the Peloponnesian War 33 years earlier, dominated Southern Greece and carried an invincible reputation. They were unstoppable, and they were coming. Thebes and the rest of the Boeotian city-states, led by Epaminondas, needed a way to fight back.
Epaminondas led a smaller force (some 6,000 to Sparta’s 11,000, though historians debate the exact numbers) to a field in front of a Boeotian village called Leuctra. The Battle of Leuctra would not only mark the beginning of centuries of Spartan decline, but also change the way Greek armies battled all the way through the conquests of Alexander the Great.
How did Epaminondas do it? How could he upend the mighty Spartan empire with a force barely half the size? The answer lay in resource allocation, patience, and 300 extremely important gay men.
If you had the misfortune of fighting against a Spartan army in the last few centuries BCE, you had to contend with a phalanx of hoplites. Thousands of men would align shoulder to shoulder, stick out their shields and spears, and push. You probably had a phalanx of your own, but against the Spartan line, you stood no chance.
Epaminondas didn’t have the numbers to directly contend with the Spartan phalanx, but he did have a specific elite force: the Sacred Band of Thebes. The Sacred Band was made of 300 hand-picked warriors paired off into homosexual couples. The idea was that lovers would fight more fiercely for each other.
Instead of a futile effort to out-push a force half their size, the Boeotians overloaded one side. They put a majority of their force on the left side, thinning out the right. They advanced this overloaded left wing before the weaker right wing, hoping to win before the Spartans could fully engage.
The Boeotian left wing, led in part by the Sacred Band, broke through the Spartan line. With enemy forces charging the side and rear, the Spartans quickly routed. When the dust settled, Epaminondas inflicted upon the Spartans one of the most decisive blowouts in Greek history.

Over 1,000 Spartans perished in the Battle of Leuctra, including their king and military leader Cleombrotus. The Boetians lost around a hundred, but exact estimates are hard to come by. By anyone’s estimate, their casualties paled in comparison. Sparta’s military reputation would never recover, and the next 200 years marked an era of Spartan decline.
Epaminondas didn’t invent the phalanx. In fact, it’s unclear who really did. There is evidence of a similar strategy in Sumer over 2,000 years earlier. It’s a fairly basic idea — everyone hold your shields together and push. But Epaminondas did advance the strategy. Others would continue to innovate on Epaminondas’ “oblique” advance, up to and including Alexander the Great.
