Battle of Scarif

"We'll take the next chance, and the next, until we win, or the chances are spent."

- Jyn Erso

The Battle of Scarif was the first major battle of the Galactic Civil War, marking the outbreak of open war between the Alliance to Restore the Republic and the Galactic Empire. The battle followed years of attacks by the fledgling Rebel Alliance against the Empire and began the five-year period in which the Alliance successfully fought to replace the Galactic Empire with the New Republic. Prior to the battle, Alliance Intelligence intercepted information suggesting that renowned scientist Galen Erso was building an Imperial superweapon capable of destroying entire planets. Alliance leadership sent Galen Erso's daughter, Jyn Erso, and Captain Cassian Andor to learn more about her father's involvement, and their subsequent efforts saw the Alliance discover the existence of the Death Star, as well as a fatal flaw in the design placed there by Galen Erso.

Though the Alliance Civil Government refused to openly oppose the Empire, Erso and Andor led a small unit of Rebel soldiers and other allies and defied orders, taking it upon themselves to infiltrate the heavily-guarded Citadel tower base on Scarif to retrieve the Death Star plans. Under the callsign Rogue One, the unit infiltrated Scarif's planetary shield in a stolen Zeta-class cargo shuttle and proceeded to wage a guerrilla assault on the Citadel's outskirts, drawing away Imperial forces so that Andor, Erso, and the droid K-2SO could infiltrate the facility. Director Orson Krennic, the former commander of the Death Star, attempted to stop Erso and Andor from stealing the plans, but the heavily-outnumbered Rebels received support from the Alliance Fleet under Admiral Raddus, whose forces engaged the Imperial Star Destroyers above Scarif and worked to destroy the Shield Gate protecting the planet.

With the Shield Gate's destruction, Rogue One was able to transmit the stolen plans to the fleet above, though all remaining Rebel ground forces were eradicated by a low-powered blast from the newly-arrived Death Star that destroyed the Citadel and surrounding area. The Sith Lord Darth Vader's forces made short work of the rebel ships that did not manage to retreat, but Princess Leia Organa managed to escape the battle in the Tantive IV; Vader pursued her to the planet Tatooine and captured her there, but the plans were already out of his reach. The plans eventually found their way to the Alliance, who used them to pinpoint the Death Star's weakness and destroy it at the Battle of Yavin.

Prelude
Following the Mission to Eadu, Jyn Erso, and Captain Cassian Andor participated in an Alliance Council meeting, where they told the gathered beings what they had learned about the Death Star, and that they needed to get the plans held at Scarif; however, most were skeptical that such a weapon existed, and those that believed it did were unconvinced that it had a deliberate weakness-on account of the fact that the news came from a criminal who was the daughter of an Imperial engineer-and thought that it would be better to hide or surrender. Disheartened, Erso walked away from the meeting, only to find that Andor and many others were still willing to go with her and fight. Together, they took the Imperial cargo shuttle that had been stolen earlier, and headed to Scarif.

Once there, Bodhi Rook transmitted the shuttle's clearance codes, which got them through the planetary shield and onto the surface.

The battle
"Make ten men feel like a hundred."

- Cassian Andor, to the soldiers of Rogue One

The battle began with Rebel Marines setting off multiple explosives on the landing pads at the base on Scarif. This attracted most of the troopers at the base, allowing Erso, Andor, and K-2SO to get inside the base and search for the Death Star plans. Soon after, the rest of the Alliance to Restore the Republic's fleet arrived to support the initial assault squadron. Following the arrival of the Alliance's fleet, they attempted to send multiple starfighters into Scarif's deflector shield to reinforce the ground assault. Multiple X-wings, and a single U-wing made it through the opening in the shield before it was closed.

Following this, Rook was tasked with opening the deflector shield so that the plans could be transmitted to the Alliance flagship above the planet. Bodhi directed Chirrut Îmwe and Baze Malbus to the master power switch for communications on Scarif. The two managed to turn off the signal disruptor, but perished doing so. Rook managed to contact the Alliance flagship and told them they had to open the deflector shield to allow the Death Star plans to be transmitted to them. Shortly after, a thermal imploder was thrown into his ship, killing him and destroying the shuttle. Once inside the base, Andor, K-2SO, and Erso made their way to the archives. After disabling the technician, K-2SO began searching for the files as Andor and Erso entered the vault. After noticing the dead technician, a multitude of stormtroopers besieged the main archive room, while K-2SO managed to hold many of them off with a single blaster pistol. After withstanding heavy blaster fire, K-2SO located the Death Star plans and marked the canister. He then locked Erso and Andor in the vault to allow them enough time to retrieve the plans, and was subsequently destroyed fending off stormtroopers.

Inside of the Scarif Citadel tower, Orson Krennic, along with two Death Troopers, opened a security door to the archive vault and began to shoot at Andor and Erso. Andor managed to kill the two troopers, but was hit by Krennic, rendering him unconscious. Erso continued her ascent to the escape hatch at the top of the vault and exited onto the roof of the Scarif Base. On top of the base was the communications dish. After reorienting it, Erso was about to send the plans to the rebels when Krennic appeared. Whilst Krennic confronted her, declaring the Empire's inevitable victory, Andor regained consciousness and made his way to the roof of the station. Right before Krennic was about to kill Erso, Andor shot the director. Far above, Gold leader gave an order for his squad mates to launch multiple ion torpedoes at a Star Destroyer, disabling it. After doing so, a Hammerhead corvette rammed into the side of the disabled ship, sending it on a collision course for another one. As the two Star Destroyers collided, they broke apart and fell towards Scarif, crashing into the orbital docking station that controlled the deflector shield, disabling it. With the shield down, Erso and Andor were able to successfully transmit the Death Star plans to the Alliance flagship above Scarif.

Immediately after the transmission of the plans, the Death Star came out of hyperspace along with Darth Vader aboard the Devastator. On Grand Moff Wilhuff Tarkin's order, the Death Star targeted the Scarif Base and fired, killing everyone at the base (including Erso, Andor, and Krennic) and destroying the Imperial security complex. Once the Alliance forces had the Death Star schematics, they attempted to jump to hyperspace, but a number of the fleet's ships were intercepted by an incoming Devastator, including the Alliance flagship. After disabling the Alliance's flagship, Darth Vader, along with other Imperial forces, boarded the ship and attempted to regain the Death Star plans. The schematics made it to the Tantive IV, but multiple rebel soldiers were slain by Darth Vader in the process. The corvette, captained by Leia Organa, jumped into hyperspace and narrowly escaped, ending the Battle of Scarif.

Aftermath
With the Death Star plans in the hands of the Rebellion, the Tantive IV was pursued by the Devastator, where Vader personally oversaw the operation. The Devastator followed the Tantive IV to the desert world of Tatooine, where Vader captured the princess and brought her to the Death Star. Imperial forces, meanwhile, searched for two droids, R2-D2 and C-3PO, the former of whom held the Death Star plans. The droids came into the possession of Luke Skywalker, who, along with Jedi Master Obi-Wan Kenobi and the smuggling partners Han Solo and Chewbacca, made his way to the Death Star and rescued Organa. Although Kenobi was killed by Vader, his former apprentice, during the escape, the princess and the others traveled to the Rebel base on Yavin 4 and participated in the Battle of Yavin. The battle was conceived after the Rebels analyzed the Death Star plans and discovered the weakness-an exposed exhaust port-which Skywalker exploited to destroy the Death Star during the battle.

Behind the scenes
"It is a period of civil war. Rebel spaceships, striking from a hidden base, have won their first victory against the evil Galactic Empire. During the battle, Rebel spies managed to steal secret plans to the Empire's ultimate weapon, the DEATH STAR, an armored space station with enough power to destroy an entire planet."
