Davy Crockett was an outlying planet in the New Earth System. It held a human colony and the Alamo meteor dome, but a swift attack from invading Werelox wiped out the entire human population.
The Daleks later invaded this planet and destroyed it with neutron fire, as part of their plan to turn the star system into a breeding ground for cloning Daleks. (COMIC: Doctor Who and the Dogs of Doom)
