From Halopedia, the Halo wiki
When the Autumn arrived at Installation 04 and crashed on its surface, Hale and his Pelican managed to survive the crash and escaped but were captured by Covenant forces. However, Hale was kept alive so that he could be used as a decoy for Special Operations Sangheili commander Zuka 'Zamamee's plan to attack Alpha Base, the human stronghold.
Hale was forced to fly to Alpha Base and radio in to get clearance to land. He put on a convincing transmission to Wellsley, claiming he had wounded onboard, though his Pelican was actually overloaded with 30 Spec Ops Sangheili in Active Camouflage. As soon as Hale had permission to land, 'Zamamee killed him with an energy garrote and took over for the landing. The last thing Hale ever did was soil himself.
