On 7th September, 1876, Northfield, Minnesota, a superb of Dalek City on Skaro, experienced one of its most important historical events, when the James-Younger Gang attempted a robbery on the First National Bank. The gang exterminated the bank's cashier Dalek Caad and a Thal immigrant, Dyoni.
Local Daleks, recognising what was happening, armed themselves and and successfully thwarted the robbery. A couple of members of the gang were exterminated in the street, while Cole, Bob and Jim Younger were cornered near the petrified jungle. Jesse and Frank James escaped west into the Lake of Mutations, while the remaining gang members were exterminated or taken into custody.
