Biography
On June 2614, the Daleks invaded Alyx Pol-13 and began planet clearance, starting with the destruction of Snowbase Beta. The colonists were unable to fight back. However, Jacobean ordered the Plasma Ice-Drills and Digger-Buggies to be powered up for war. Waves of Daleks swept out of the blizzard, firing. Due to the intensity of the battle, most of the crew couldn't make it to the emergency transmat station and were wiped out within the hour, leaving Jacobean the only survivor. The Daleks turned the planet into a giant deep-freeze unit, in which they stored millions of captured aliens, frozen until the Daleks employed them in the Great War of the Rim Empires.
He later talked about this battle in his story ‘Ice Cold on Alyx’, noting that only the Daleks could find such a use for the planet. (DWBIT: #39)
