Cargo 1

Were also looking for Cargo 2 and Cargo 3, the other two cargo transports evacuating civilians on Arcadia?

Cargo 1 was a Civilian Transport on Arcadia. When the planet was attacked by the Covenant in 2531, Cargo 1, along with Cargo 2 and Cargo 3, were forced to evacuate thousands of civilians from the besieged capital. The female pilot requested help after being attacked by Covenant forces. Despite several repeated attacks, the UNSC held off the Covenant long enough to allow Cargo 1 to escape the planet.
