Operation: TREBUCHET

Operation Trebuchet

UNSC forces engage insurrectionists over Eridanus II, a rebel stronghold in the outer colonies, during Operation: TREBUCHET.




Operation: TREBUCHET was a twelve-year UNSC operation to quell growing unrest and insurrectionist activities in the outer colonies from 2513 until the start of the Human-Covenant War in 2525.  The operation spanned many star systems and combat theaters, and was successful in slowing or stopping several rebellions, though at the cost of over one million civilian lives.  The operation was put on hold at the start of the war with the Covenant and was not restarted.



These events are depicted in the novel Halo: Contact Harvestwhich was the subject of a Halo Book Club on September 29th, 2014.
