The Fall of the Twelve Colonies (also known as The Fall, the Cylon attack, Cylon holocaust or Second Cylon War) is a devastating, genocidal attack that re-ignites the conflict between the humans of the Twelve Colonies of Kobol and their creations, the robotic Cylons.

The Cylons compromise Colonial defenses by infiltrating their military and civilian society with models that look human. One such Cylon seduces the brilliant Dr. Gaius Baltar, fooling him into contract work that gives her access to the Colonial Defense Mainframe. Her work on the project compromises Baltar's Command Navigation Program, creating countless programmer backdoors.

After Baltar's CNP is sufficiently distributed throughout the Colonial Fleet, the Cylons return from their forty-year exile and launch a devastating attack on the Colonies. The backdoors in the CNP enable the Cylons to use various electronic attacks that completely by-pass Colonial electronic defenses, and inflict varying degrees of damage to Colonial military computers.

Viper squadrons experience complete power loss upon engaging the enemy, while battlestars and other support ships suffer an abnormally-high number of "equipment malfunctions" during their engagement of the enemy. This infiltration of Colonial systems - when combined with the "complete surprise" that they achieve - enables the Cylons to sweep the Colonial Fleet aside with minimal losses; a triumph beyond their most optimistic projections (Downloaded).

The attack begins when a massive Cylon fleet jumps from The Colony into the orbits of each of the Colonies. No one on the Colonies can detect them except the battlestars in orbit which try to engage but are shut down by the CNP weakness. After getting into position, the basestars launch massive pods each containing multiple nuclear missiles which break apart and spread out once reaching a certain point. All of the Colonies are nuked at once and the Hybrid reports that all of the Colonies are burning to the Cylons (The Plan).

Picon Fleet Headquarters are destroyed in the opening wave of the attack, as are 30 battlestars. In response to this, Admiral Nagala takes command of the Colonial Fleet aboard the battlestar Atlantia, and instigates a counter-attack against the enemy. Additionally, the Colonial government orders a full stop on commercial and civilian space-travel, leaving hundreds of non-military vessels stranded in surrounding space-lanes.

After the devastating assault on Picon, Colonial President Richard Adar broadcasts an unconditional surrender to the Cylons, but his gesture is completely ignored. All senior members of the Colonial government, including Adar, are henceforth presumed killed or missing, and an emergency government contingency mechanism activates to seek out surviving government officials. The space-bound Secretary of Education Laura Roslin is the only one to acknowledge this beacon. Sworn in on the government-chartered passenger liner Colonial Heavy 798, she becomes the new President of the Twelve Colonies.

While this exchange of power is taking place, the Cylons proceed to destroy each Colony's population and strategic centers by means of nuclear bombardment. One of the targets - Caprica City - is annihilated in a 50 megaton nuclear detonation. However, not every city on Caprica is destroyed in the attack; much of Delphi remains intact and is occupied by Cylon ground forces a short time later (Bastille Day).

Battlestar Galactica, approximately 300 million miles from Caprica, is unaffected by the Cylons' computer infiltration as its computer systems were never networked or updated with the compromised CNP. This anti-infiltration policy, used in the First Cylon War, was maintained by all of Galactica's commanders, including William Adama, through peacetime and despite advances in Colonial technology.

With the primary fight against the Cylons centering around the orbit of Virgon (as determined by a tactical plot of all ships in the solar system by Lieutenant Gaeta), Galactica prepares itself for a confrontation despite the fact that the ship is unarmed, having destroyed all large munitions as part of its decommissioning ceremony. To complicate matters further, the battlestar has plenty of pilots, but hardly any Vipers left to fly; its last Viper Mark VII squadron was destroyed in a Cylon attack shortly after the decommissioning ceremony.

Fortunately, the battlestar holds 40 Viper Mark IIs on board as part of its expected conversion into a museum. These Vipers are of an old but robust design resistant to Cylon infiltration; many on-board instruments are analog and were never equipped to use the Command Navigation Program that dooms newer Colonial fighters.

Galactica arms and deploys these old Vipers, repelling several attacking Cylon Raiders in its first sortie of the new war. Unable to return fire, the battlestar survives a direct hit from a Raider-launched tactical nuclear missile. However, 85 crew members are lost when damage to the fire suppression system necessitates the venting of the port flight pod's atmosphere to prevent the fuel lines from igniting, thus preventing the destruction of the ship.

After the skirmish, Galactica receives word that Atlantia has been lost in the counter-offensive against the Cylons. Numerous additional battlestars have been destroyed as well. Commander Adama takes command of the Colonial Fleet, and sends a wireless transmission to any surviving forces to rendezvous at Ragnar Anchorage, a munitions depot that carries desperately needed ordnance for Galactica's point-defense batteries and fighters. It is from Ragnar Anchorage that they will commence a second counter-attack against the Cylons. Galactica successfully jumps to Ragnar, skipping past the bulk of the enemy fleet that stands in her way.

Meanwhile, President Roslin begins clustering stranded Colonial vessels and forms a fleet. Roslin's efforts retrieve at least three Mark VII Vipers and find Lt. Sharon "Boomer" Valerii (the only survivor of Galactica's compromised Mark VII fighter squadron) and her Raptor. Boomer successfully locates additional civilian craft before a scouting Raider finds the convoy. Fearing imminent attack but unable to rescue any passengers from the convoy's sublight ships in time, Roslin orders the FTL-capable ships to jump to Ragnar, where a re-armed Galactica can protect them. Shortly after, the defenseless sublight ships and their passengers are destroyed by a Raider squadron.

Aftermath

Few Colonials survive this holocaust and many that do are captured by Cylons for experimentation (The Farm). On Caprica, Samuel Anders and the Caprica Buccaneers escape the devastation while in high altitude training in the mountains at the time of the attack. Together with other survivors, they later form a resistance against the Cylons until a rescue mission led by Kara Thrace, with the help of another copy of Boomer, rescues them from Caprica and takes them back to the fleet.

Additionally, Galactica is not the only battlestar to endure the attack. An attack at the Fleet Shipyards at Scorpia destroys several battlestars, but Pegasus, only partially operational at the time, manages to escape by doing a blind jump. However, Galactica and Pegasus remain unaware of one another's fate until months later.

Eight Cylons manage to make their way into the Fleet as well: two Sixes, one of which becomes known as Shelly Godfrey while the other is a prostitute, Boomer who is a sleeper agent, a Leoben who becomes obssesed with Starbuck before being airlocked, a Doral who suicide bombs himself in a failed attempt to do real damage, a Three who is a Fleet reporter, a Simon who has a family and later kills himself outside of resurrection range to avoid betraying his family and the Cavil who was responsible for the attacks and the war that followed (The Plan).

As for the Cylons, when the Final Five are discovered to be within the human fleet during the Battle of the Ionian Nebula, they are split into two factions in a civil war. In the aftermath of the Cylon Civil War, a surviving basestar of the rebel faction and its Cylon inhabitants join the human fleet. Later, after the Battle of the Colony, the surviving Twos, Sixes, and Eights join the Colonials on the new Earth. The rest of the Cylons are destroyed by the Galactica in the battle except for the Rebel Centurions who are set free to find their own destiny. Among those killed in the battle are Cavil, a Number One copy who is indicated to have been responsible for the second Cylon War and Boomer, who betrayed the Colonial Fleet completly after accepting the truth about her Cylon side, but helps the Colonials one last time out of sympathy for Hera Agathon and due to owing Admiral Adama one. Also killed in the battle is Final Five Cylon Tory Foster who is killed by Galen Tyrol for murdering his wife. Samuel Anders also dies later by piloting Galactica and her Fleet into the sun and like the other Cylons killed in the battle, they are unable to resurrect as resurrection was destroyed in the Battle of the Resurrection Hub.
