The Drakh attack of Earth began the war with the Drakh.
Interstellar Alliance president John Sheridan takes command of the IAS Excalibur and IAS Victory and leads the EarthForce and ISA fleets to victory.
The Victory was destroyed in the battle, but the Excalibur survived.
Despite defeating the Drakh Sheridan's fleet was unable to prevent the Drakh from releasing the Drakh plague into Earth's atmosphere, infecting everyone on the planet. Within five years the plague will destroy all life on the planet.
