Battle of Circinius IV

The Battle at Corbulo Academy was a conflict between UNSC and Covenant forces on the colony of Circinius IV in mid-2526.

Prelude
Even after the first engagements on Harvest, ONI Section II kept the Covenant invasion secret from a large portion of the general population as of 2526. This included the cadets and staff of the Corbulo Academy of Military Science on Circinius IV. However, the Academy's superintendent, General Black, was informed. As preparation for a possible attack, Black discreetly increased the readiness of the UNSC Marine garrison posted in the academy and authorized limited communications blackouts under the guise of routine maintenance procedures.

Battle
At some point in 2526, the Covenant began an assault on Circinius IV, targeting in particular the Corbulo Academy of Military Science with three SDV-class heavy corvettes. Locally stationed Marines provided an initial defense of the Academy, and the evacuation of the cadets via the school's space elevator was begun immediately. The UNSC forces soon deployed Orbital Drop Shock Troopers directly onto the campus. However, one of the Covenant corvettes fired on the elevator, causing it to collapse on the school and halt the evacuation.

Corbulo's officer cadets were caught off-guard by this attack, scattering into the surrounding areas, and many fought against the Covenant in close combat. Spartan supersoldiers John-117, Kelly-087, Fred-104 and others later arrived to reinforce the academy's defenses.
