0 BBY, several weeks before the Battle of Yavin, the Alliance to Restore the Republic captured the Imperial BFF-1 bulk freighter .
After learning that the Empire was building the
Death Star, a battlestation capable of destroying a planet, the Alliance attempted to discover which contractors were involved in its construction.
The battle Edit
As part of this operation the
Mon Calamari privateer Tuz helped to capture the Sidral II while it transported a cargo of military hardware,  including timers and  fusion cells. The Alliance dispatched the  CR90 corvette to rendezvous with the Frazier freighter and transfer its cargo. The operation was interrupted by the Imperial-class Star Destroyer , but the Rebel forces were able to complete the transfer before escaping to Immortal hyperspace.
Part of the stolen shipment had passed through an Imperial repair dock near
Coruscant, the Imperial capital. Alliance High Command decided to launch an attack on the facility in the hopes of crippling the infrastructure that was servicing ships working on the Death Star.
