Operation: PROMETHEUS

Summary
DATE: July 27, 2537 - August 2, 2537

LOCATION: Unknown system, above the asteroid K7-49.

Involved: UNSC, Spartan-III's, and Covenant forces.

The battle was a suicide mission ordered by the ONI Brass. However, it was not in vain, because it was necessary for the survival of the UNSC. It took place on K7-49, a volcanic asteroid which also served as a Covenant shipyard that was only a 2 week Slipspace journey from UNSC space. The mission was to destroy its plasma reactors, thus causing the metal to cool and harden, halting Covenant ship construction. The success of the mission would save countless lives.

The outcome was Alpha Company succeeding, but at a great cost. All 300 of the Spartan-III's died in the battle.

Historical Significance
This is most likely an allusion to the Battle of Thermopylae. There were 300 Spartans at both battles, both were a suicide mission, both were fought in order to slow the enemy down enough for their sides to prepare and survive longer, and in both all the Spartans died.

Trivia

 * According to Ghosts of Onyx, Hunters were first seen by humans during this operation, although all of the participating Spartan-IIIs were killed. However, Hunters are prominently featured in Halo Wars, which takes place in 2531, six years prior.
 * Prometheus was the son of Iapetus who was one of the Titans. He is a rebel god.
