Space engagements over Reach

During the Fall of Reach, a large battle in space over Reach took place on August 30th encompassing numerous ships from both sides of the battle.

HYPODERMIC
The UNSC Circumference was a part of Operation: HYPODERMIC. Due to the secrecy of the operation, the Circumference was struck from the computers of Reach Gamma Station. Covenant intrusion software detected this oversight and deployed forces to the Station.

Gamma Station
In order to effectively tackle both problems, John-117 split his SPARTAN-IIs into two groups. Three SPARTAN-IIs (himself, Linda-058, and James-005) were to be deployed to the station to scrub the data on the Circumference.

When the three SPARTANs arrived at the space station, the docking bay doors were sealed and the station was not spinning.

Later actions
At some point after the mission, a and an  battled each other near the station.
