Vowed Himself to the Infernal Gods
[Publius] Decius Mus [was an early] Roman [Republic consul] who, when faced with an impossible battle, vowed himself (according to an old ritual of human sacrifice) to the infernal gods, along with whoever he killed and who killed him. He then charged the enemy line singlehanded and opened a hole the Roman Army under the other consul (Rome in those days sometimes took the field with both presidents) then used to defeat the enemy.
