When he awoke, Pelopidas told his dream to the other captains, and as they were wondering what to do, a colt of a bright chestnut colour ran through the camp.
‘So,’ cried a soothsayer, ‘the sacrifice is come. Expect no other, but use that which the gods have sent.’
Then the colt was solemnly offered in sacrifice at the tombs of the maidens. And the army was content, for the gods, they were sure, would give them the victory.
Until now a Greek army had always been drawn out in a long, narrow line. But Epaminondas arranged his men in a new way. His left wing was only a few men wide, but it was fifty men deep, which made it unusually strong.
Pelopidas with his Sacred Band was placed in front of the heavy left wing, while the rest of the army was arranged as usual.
The Spartan cavalry attacked the Theban horse, but it was soon driven from the field. Cleombrotus was with his right wing and he now led it against the strong left wing of the enemy.
Bravely as the Spartans fought, they could not withstand the onslaught of the left wing, led by the Sacred Band.
Cleombrotus fell and was carried from the field, wounded to death. The Spartans still struggled bravely, although their king was slain. But when Epaminondas called to his men, ‘Give me a step more and the day is ours,’ the Thebans spurred on to one more effort, broke the Spartan line and put it to flight. The Thebans had won the day, with but little loss of life, while four hundred Spartans had been slain.
Cleombrotus was the first Spartan king who had fallen on a battlefield since the fatal day of Thermopylae.
The terrible news of the defeat of Leuctra was sent to Sparta, but the citizens were too well disciplined to show the dismay which they must have felt.
