Biography
A single Dalek saucer and its crew of three Daleks survived the destruction of the New Dalek Empire at the hands of the Meta-Crisis Tenth Doctor. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) 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 himself 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 in 1941, with of the three Daleks posing as Ironside prototypes. Concerned, British Prime Minister Winston Churchill alerted the Eleventh Doctor, who took a month to arrive.

The first Ironside was deployed in the face of a Luftwaffe formation headed for London. With its gunstick, the Dalek quickly destroyed a flight of Stukas. This was witnessed by the Doctor and his companion Amy Pond. Following the deployment, Edwin Bracewell presented the Ironside to the Doctor, who immediately recognised it as a Dalek. Identifying as a British soldier, the Ironside feigned ignorance to the Doctor's identity and claimed, as per Bracewell's instructions, that it was to serve the Allied cause against the Germans and win the war.

Within the Cabinet War Rooms, the Ironside used its suction cup to carry files, passing the Doctor as it did so. Soon after, the Ironside offered Professor Bracewell a cup of tea. Holding a cup on a tray, the Ironside offered the Doctor a cup of tea. Enraged, the Doctor slapped the tray out of the Ironside's grasp before physically assaulting it as the Ironside repeated its supposed objective. Once the Doctor identified himself, and that the Ironsides were Daleks, the first Ironside acknowledged that he was correct and had its partner review and transmit a record of his testimony to the progenitor, which accepted the testimony.

As the Doctor instructed everyone to get back, Churchill ordered marines into the room. A pair of marines quickly entered, only to be exterminated by the second Ironside. When Professor Bracewell attempted to assert himself as their creator, the first Ironside blasted off his left hand, revealing him to be an android they had created. Anticipating victory, both Ironsides teleported back to their ship.

Aboard the Dalek ship, all three Daleks watched as the progenitor entered the final phase. 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 first of a New Dalek Paradigm. The new white Supreme Dalek deemed that the trio of older Daleks, grown out of the DNA of Davros, (TV: The Stolen Earth) were "impure". The three Daleks accepted this and allowed themselves to be disintegrated by the new Daleks; the first Ironside was the first to be exterminated, by the blue Strategist Dalek.
