Battle of Circinius IV

The Battle of Circinius IV was a conflict between UNSC and Covenant forces on the colony of Circinius IV in mid-2526. It was not only one of the first battles of the Human-Covenant War, but also one of the first deployments of SPARTAN-IIs.

Prelude
After the first engagements on Harvest, ONI Section II kept the Covenant invasion secret from a large portion of the general population. 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
"We are under attack!"

- Cadet Thomas Lasky

At some point in 2526, the Covenant began an assault on Circinius IV, targeting the Corbulo Academy of Military Science with three s. 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. Orbiting UNSC vessels 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. Since all the cadets and staff had converged near the elevator for evacuation, the collapse of the elevator killed many members of the academy. Covenant ground forces soon attacked. "John-117"

- Michael Sullivan Corbulo's officer cadets were caught off-guard by this attack. General Black was killed within minutes of the attack; Colonel K.L. Mehaffey attempted to organize the surviving cadets inside the tunnels, though she too was quickly killed. Soon, whatever UNSC forces left were eliminated and four members of Hastati Squad, Cadets April Orenski, Thomas Lasky, Chyler Silva, and Michael Sullivan, were the only human survivors on the entire planet. SPARTAN-II Blue Team were then subsequently deployed in response to the cadets' distress beacon. Spartan John-117 arrived just in time to rescue the cadets from a Sangheili Zealot. He then broke open the cadets' weapons lockers and allowed the cadets to arm themselves.

The Spartan led the survivors to the academy's exterior, where they were ambushed by Kig-Yar snipers. Cadet Sullivan was wounded during the firefight, but survived. After dispatching the snipers, they retreated from the combat zone in General Black's personal Warthog. During the drive however, they came under heavy fire from more Kig-Yar. Silva was killed and the rest group was almost killed by a pair of Hunters. John-117 depleted all his ammunition killing one of the Hunters, and was left with only a single grenade. He planned to take on the remaining Hunter alone, buying the surviving cadets time to escape. However, Cadet Lasky volunteered to distract the Hunter while John got into position. Lasky successfully drew the Hunter's fire, allowing John to plant the grenade under its armor. The resulting detonation blew the Hunter to pieces.

As morning arrived, the group reached their Pelican dustoff point without more casualties just as the Covenant began glassing the planet. Impressed by Lasky's courage, John gave him a fragment of the Hunter's armor.

Aftermath
While the academy and virtually the entire planet's population was wiped out, the battle would have a lasting impact on Thomas Lasky, who would not only survive the war, but would go on to become Captain of the UNSC Infinity. Four years after the war, he would be reunited with John-117 on Requiem, and would play a major role in saving Earth from the Ur-Didact.
