Thal-Dalek War

The Thal-Dalek war was a conflict between the Thals and the Daleks which took place over a long time. There is scant record of most of its events. It was known in the Daleks' own language as Pa Jaski-Thal, which translated as "The liquidation war against the Thals". (PROSE: Remembrance of the Daleks)

Some time after the Thousand Year War, the planet Skaro had become a nuclear wasteland. Its principal features were the Petrified Forest, 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)

However, the Daleks survived. Accounts of the first conflict and the part the travellers played in it passed into Thal legend.

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)
