One ship containing three Daleks escaped that defeat after accidentally falling through time, where it then picked up a trace of a Progenitor device that contained pure Dalek DNA. However, because these Daleks had been created from the DNA of Davros, the Progenitor did not accept them as true "Daleks"; to restart the Progenitor, the Daleks trick the Eleventh Doctor into activating it for them during World War II by declaring them Daleks (which the device accepts). Once activated, the Progenitor device created a new "Paradigm" of Daleks that destroyed the previous Daleks and escaped through time, forming a new race of Daleks. Eventually learning of the Time Lords' survival alongside various other races during the events of "The Time of the Doctor", the Daleks laid siege on the planet Trenzalore for centuries to either resume the Time War or kill the Doctor before he could release the Time Lords back into the universe. In the end, the Dalek fleet was wiped out by the Eleventh Doctor during the first phase of his regeneration.
