Operation: PROMETHEUS

Summary
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. The mission was to destroy its plasma reactors to disable the shipyard, halting Covenant assaults. The success of the mission would save countless lives.

The outcome was Alpha Company succeeds, but at a great cost. All 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. This is most likely because the only people to see the Hunters, the crew of the Spirit of Fire, were not in contact with the rest of the UNSC.
