Battle of Circinius IV




The Battle of Circinius IV was a Covenant attack on the planet Circinius IV and Corbulo Military Academy located on the planet.  Though the attack occurred over a year after humanity made first contact with the Covenant on Harvest, only a select few were aware of the Covenant's existence due to the Office of Naval Intelligence keeping them a secret from the general population.  

The battle was a complete surprise to the people on Circinius IV, forcing an emergency evacuation of the planet and Corbulo Military Academy.  Blue Team, led by John-117 was sent planetside to assist in the evacuation, though they were only able to successfully evacuate three people, April Orenski, Thomas Lasky, and Michael Sullivan.



These events are depicted in the movie Halo 4: orward unto Dawn, which was the subject of a Halo Book Club episode on September 13th, 2017.
