A Pyrrhic victory is a victory with devastating cost to the victor; it carries the implication that another such will ultimately cause defeat. The phrase is named after King Pyrrhus of Epirus, whose army suffered irreplaceable casualties in defeating the Romans at the battle of Heraclea in 280 BC and Asculum in 279 BC during the Pyrrhic War. In both of Pyrrhus's victories, the Romans had more casualties than Pyrrhus did. However, the Romans had a much larger supply of men from which to draw soldiers, so their casualties did less damage to their war effort than Pyrrhus's casualties did to his.
