 * The Battle of Harvest. Preston Cole's fleet engages the alien warships responsible for the decimation of the Harvest colony. Six years after the planet was attacked, UNSC forces emerged victorious at the cost of two-thirds of the battle group.
 * Cole is promoted to Admiral upon his return to Earth and learns that a number of outlying colonies have been destroyed, leaving behind no survivors.
