Operation: FORTRESS SIEGE

Operation: FORTRESS SIEGE, also known as the Recapture of the Epsilon Eridani system, is a major Post-Covenant War operation conducted by the United Nations Space Command and the Concord of Reconciliation. UNSC High Command and members of the Concord met to plan the retaking of the Epsilon Eridani system in January of 2553, following the end of the Human-Covenant War.

Background
Following the end of the Human-Covenant War in December of 2552, the UNSC looked to retake the Epsilon Eridani system. After losing the system in August of 2552, the UNSC wanted to recapture a strategically important location in Sector One. The military fortress world known as Reach had been glassed, but personnel from the Office of Naval Intelligence stressed the importance of the system. With millions of humans displaced because of the war, the UNSC figured they had a chance to turn the system into a sanctuary for civilians.
