Thousands of soldiers[3]


The Battle of Thermopylae[1][4] was a battle that took place in 480 BCE and prominently featured 300 Spartans[1] defending Greece at Thermopylae.[2]


Soldiers during the battle employed spears, shields and swords. The 300 Spartans managed to successfully fight off the Persians.[3]


By the 26th century, the story of the battle was cherished and well known. Dr. Catherine Halsey believes that the story is romanticized to the point of fanaticism. Nevertheless, she did invoke the idea of the story by naming the SPARTAN-II program after the Spartans in the Battle of Thermopylae.[2]

After the program actually began, SPARTAN-IIs were taught about the battle itself on their first day of training by the AI Déjà.[3]

Master Chief Petty Officer John-117 also references the battle during his service, such as when he compares the Massacre at Eridanus Secundus to the Battle of Thermopylae in response to Vice Admiral Danforth Whitcomb's comparison of it to the Battle of the Alamo.[4]
