The Battle of Galileo Base is a battle taking place during the Requiem Campaign when Jul 'Mdama's Covenant and the Prometheans attacked the UNSC's Galileo Base.

Prelude

In February 2558, as Doctor Catherine Halsey studied one of the Requiem slipspace artifacts aboard the UNSC Infinity, she was contacted by Covenant Supreme Leader Jul 'Mdama in secret. 'Mdama suggested that they could help each other and questioned what Halsey knew of the Prometheans. After a failed attempt to get useful information out of Spartan Gabriel Thorne, 'Mdama promised to provide her with proof of the true nature of the Prometheans which Halsey had been kept unaware of.

During these events, following a successful tap into the Forerunner communication network utilized by Covenant forces, Fireteam Crimson was sent to chase 'Mdama through Requiem portal system. After Crimson chased him to "the Cauldron," 'Mdama purposefully dropped "the Didact's Gift," a Durance containing the "soul" of a Promethean Knight: a human digitized by the Composer during the New Phoenix Incident six months before. 'Mdama's intention was for Halsey to receive the Gift as the proof while making it appear that he had dropped it by accident while fleeing Crimson's pursuit. As planned, Crimson recovered "the Didact's Gift" and were ordered to transport it to Galileo Base for study before it would be transported to the Infinity.

Battle

First Covenant attack

As scientists at Galileo Base studied "the Didact's Gift" to make sure it was safe for transport to the UNSC Infinity, Spartans Robert Dalton and Jared Miller detected Covenant forces on their way, including several dozen Phantoms. The Phantoms began dropping off massive numbers of Covenant troops into the base, including several Ghosts. However, Fireteam Crimson managed to fend off the repeated waves as Miller and Spartan Commander Sarah Palmer realized that the base's defenses were offline and couldn't be activated remotely either.

As the battle continued, Palmer contacted Doctor Shannon Owen who realized that Doctor Cameron Alexander had gone against her orders not to divert power away from the base's defenses in order to power a mini-reactor. As a Hunter pair was dropped into the base, Miller was able to determine where the turret power had been routed to and directed Crimson to the location. Fighting through the heavy Covenant forces, Crimson managed to reactivate the turret defenses which shot down the attacking Covenant Phantoms. With the Phantoms destroyed, Crimson was able to clear out the remaining Covenant forces.

With the Covenant forces eliminated, Miller reported that the Forerunner communications net utilized by the Covenant that Crimson had previously tapped into was paying off as he was able to detect that the entire Covenant net was talking about retrieving the Promethean soul. Dalton reported that Fireteam Majestic was closest to transport "the Didact's Gift" to the UNSC Infinity and Palmer ordered them deployed to Galileo Base to retrieve the package while Crimson stayed to protect the base.
