The Cylon War, (sometimes referred to as the First Cylon War), is a twelve-year major conflict between the humans of the Twelve Worlds and their creations, the Cylons.

Within a decade of their introduction to Colonial society, the Cylons turn on their human creators. Humanity responds by unifying their once fractured coalition of worlds into a federal republic, with each of the Twelve Worlds signing the Articles of Colonization.

Man Versus Machine

The ensuing conflict is fought on the surface of the Twelve Worlds and other Colonial planets, with engagements taking place on Tauron and Medra. Amassing forces of several models - including Centurions and U-87 Cyber Combat Units - the Cylons affect major damage to Caprica City, assaulting the city from the ground with tanks and from the air with basestars and Raiders.

A stipulation of the new Articles of Colonization is the construction of battlestars to defend each of the Twelve Worlds, supplemented by other military spacecraft including the Viper fighter and the workhorse, multi-function craft called the Raptor. These vessels go head-to-head with their Cylon counterparts in space, which utilize computer viruses to infiltrate Colonial computer networks, undermine defenses and disable vessels.

By the tenth year of the war, the Twelve Colonies have suffered heavy losses to the Cylons. Colonial forces have launched Operation Clean Sweep, however their efforts have failed to halt the Cylon advance, despite propaganda to the contrary. Viper pilot Deke Tornvald is considered a hero in Colonial society for his 30 kills, but in reality the Colonial officer is battle weary. The Cylons have established their own territory abutting Colonial sectors including Sector 12 - the location of a major battle resulting in the loss of the battlestar Archeron.

With many vessels suffering heavy damage in the fight with the Cylons, several Colonial ships, including the battlestars Valkyrie and Osiris, are pulled from the line for covert activiities. Publicly declaring these vessels and their crews lost, Colonial admiralty positions this "Ghost Fleet" in a hidden location within Cylon space. It is from here that the stealth battlestar Osiris launches a mission to nearby Djerba - touted as a turning point in the war. Jumping into orbit of Djerba, Osiris engages a Cylon baseship while deploying a contingent of Vipers and the Raptor Wild Weasel to the former Colonial world's surface. While Osiris is destroyed in the ensuing battle, several officers - including Coker Fasjovik and William Adama - make it to the Cylon stronghold and attempt to execute their orders.

Escorting civilian scientist Becca Kelly, Toth, Fasjovik and Adama come under fire from Cylon Centurions, resulting in the loss of Toth. As the three remaining Colonials travel to a Cylon communications relay, Kelly attempts to feed information to the enemy in the guise of a computer virus. Discovering the ruse, Adama shoots Kelly and escapes with Fasjovik. While appearing to be a failure to Adama and Fasjovik, the mission proves successful - Kelly provided false information to the Cylons, procured by the Colonial Admiralty, and the Ghost Fleet is allowed to make a surprise attack on key enemy targets.

Armistice and Aftermath

The Cylon War ended abruptly when the Cylons ceased hostilities and offered to sign an armistice, twelve years (4,571 days) into the War. Shortly after, the Cimtar Peace Accords were signed by both parties, and man and machine parted ways.
Cylon Relations and Subsequent Seclusion

As part of the Accords, a line is drawn between Colonial and Cylon territories, and the Armistice Station is built to maintain relations. However, after signing the Accords the Cylons retreat into seclusion, and diplomatic relations run stale. The reasons behind their seclusion were never fully understood by the Colonial Government or military.

Colonial Rebuilding

As a result of the Cylon's uprising, the Colonial Government enacts a ban on research pertaining to artificial intelligence, for fear of more trouble. However, despite fears over A.I., colonial technology continued to advance elsewhere, mainly in computer networking and interstellar navigation. One of the bigger breakthroughs came with Dr. Gaius Baltar's Command Navigation Program, an operating system that was adopted fleet wide by the Colonial military, and even by civilian operators, which allowed greater networking and automation aboard Colonial craft, and required only half the crew compared to older Colonial craft.
