Thal-Dalek War

The Thal-Dalek war was a conflict between the Thals and the Daleks which took place over a long time.

Skaro
Some time after the Thousand Year War, the planet Skaro had become a nuclear wasteland. Its principal features were the petrified jungle, in which the Thals lived, and the city of the Daleks. The First Doctor and his companions, Ian, Barbara and Susan, visited Skaro at this time and led some of the Thals to attack the Dalek City. They disabled the power generator and deprived the Daleks of the static electricity they needed to move about the city, (TV: The Daleks) and then created their own. The Thals' raid on the City became known as the Thal-Dalek battle, (AUDIO: Return to Skaro) while the Third Doctor and Taron identified this wider period as the First Dalek War, (PROSE: Doctor Who and the Planet of the Daleks) a name also used by Federation Archivist Ven Kalik to refer to the Daleks' invasion of Earth and its colonies in the 22nd century. (PROSE: Prelude Deceit) Accounts of the first conflict and the role of the time travellers passed into Thal legend. (TV: Planet of the Daleks, AUDIO: Return to Skaro)

Survivors of the Thal-Dalek battle hid in the secret incubation level beneath the rest of the city. They were reorganised by the Dalek Supreme who was able to establish a link between the new Thal City through the manipulation of the Thal's Chief Scientist, Tryana. Fifty cycles after the original battle, the Dalek Supreme raised another army and launched an assault on the Thal City. The Daleks were ultimately forced into retreat but the Thal defences were weakened. Excessive levels of power fed into the Dalek City from the Thal City destroyed the Daleks before they could launch a second wave. Though victorious, the Thals feared other Daleks resided elsewhere on Skaro and resolved to be ready for future hostilies. (AUDIO: Return to Skaro)

Beyond Skaro
Circa 2540, the Daleks had built a base on the planet Spiridon. They planned to launch an army of ten thousand Daleks across the galaxy. They hoped to render the army invisible by study of the native Spiridon humanoids. This plan failed. The Daleks could only remain invisible for a short time.

The Third Doctor helped a taskforce of Thals, who by this time had interstellar spaceflight, to defeat the Daleks, this time using the ice core of the planet to freeze the Dalek army. (TV: Planet of the Daleks)

The Thals also fought against the Daleks in the Great War which began in the 41st century. (PROSE: The Evil of the Daleks) In later years, the Daleks launched the campaign Pa Jaski-Thal, a "liquidation war" against the Thals. (PROSE: Remembrance of the Daleks)

The Thals fought the Daleks on the planet Terakis and destroyed the planet with a bomb in order to lure half of the Eighth Fleet into a trap which succeeded despite the natives of Terakis killed. (PROSE: War of the Daleks)

The Thals fought alongside the Time Lords against the Daleks in the Last Great Time War, though relations between the allies were tense due to the Thals resenting following Time Lord commands and believing them just as guilty as the Daleks of altering Thal history. (AUDIO: Temmosus)
