History
A single Dalek Saucer and its crew of three Daleks survived an encounter with the Doctor and fell through time to 1941. They acquired an original Progenitor device, which could create new Daleks, but the device did not respond to them because it did not recognise them as Daleks. The three decided to trick the Doctor into proving to the Progenitor that they were, indeed, Daleks.

They created Edwin Bracewell, an android that was programmed to think of itself as a British scientist who constructed a pair of robot war machines, and provided him with charts and testing results realistic enough to take to the British Army to use in their war with the Nazis. Two of the three Daleks posed as Ironside prototypes. Bracewell rolled out a war-designed variant of the Dalek and put them into key points within the Allied Forces. When not used in battle, they did small tasks such as providing tea to keep up their ruse as just being advanced robots. Winston Churchill informed the Eleventh Doctor of the Ironsides.

When the Doctor arrived a month later, he was furious to discover that the Ironsides were Daleks. When his attempts to convince Churchill of the truth failed, the Doctor confronted the Ironsides directly and declared that he was the Doctor and they, the Daleks, were his enemies. This was recorded by the Ironsides and sent to the Progenitor, which accepted the identification and the Daleks' command to create the new Daleks.

The Ironsides immediately dropped their ruse, revealed Bracewell as an android by blasting off his hand, killed two soldiers, and returned to their ship in orbit. They were followed by the Doctor in the TARDIS. The Doctor confronted them and held the Daleks at bay with a "TARDIS destruct mechanism," actually a Jammy Dodger. The Daleks revealed their intentions and created five new Daleks. The new Supreme Dalek decided that the trio of older Daleks were "impure." The three Daleks accepted this and allowed themselves to be disintegrated by the new Progenitor Daleks, who went on to establish the New Dalek Paradigm. The bronze Dalek was destroyed alongside an Ironside by the Strategist Dalek, while the last Ironside was destroyed by the Drone. (TV: Victory of the Daleks)
