"I am your soldier!" - Dalek Ironside
The Dalek Ironsides were three Daleks who had survived the battle of the Medusa Cascade against the 10th Doctor. They fell back in time to 1940 where they posed as the creation of android Edwin Bracewell.
History[]
After the defeat of Davros and the New Dalek fleet during the war in the Medusa Cascade against the 10th Doctor and his companions, one Dalek saucer with three members of the crew had survived. They had with them a Progenitor containing pure Dalek DNA, with this they could recreate the Dalek race but as they were made from the cells of Davros the progenitor deemed them as unpure and would not create new Daleks.
They created android Edwin Bracewell and provided him with charts and testing results realistic enough to take to the British Army. 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. 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 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 inferior. The three Daleks accepted this and allowed themselves to be disintegrated by the new Progenitor Daleks.
