Just a bit of nitpicking: The Term Jutland Peninsula refers (in english) to the entire Penisula, the german Part included.
Jutland as a cultural-geographical term mostly only refers to the Danish part of the peninsula, from Grenen to the Danish-German border.
So I think the citys from Schleswig-Holstein and Hamburg should be included.
