One fleet attacks the UNSC ships, while another takes out the MAC cannons and send in troops to land on Reach. The UNSC try to split their 50+ remaining forces to engage the Covenant, but there are too many platforms to cover and too many casualties.

Emile and SPARTAN-B312 head to platform D in the ship breaking yards to meet with Captain Keyes and to deliver Cortana over. Emile dies when he is stabbed by a Covenant Zealot wielding an Energy Sword. SPARTAN-B312 successfully delivers the package to the Autumn and allows the vessel to escape by destroying an incoming Covenant battlecruiser using a mass driver. The Pillar of Autumn, pursued by a dozen Covenant vessels, retreats from the system, heading for Installation 04.
