From the beginning of the 1960s onwards an occupation of Denmark is an important theme in the Warsaw Pact and GDR military exercises and manoeuvres. This is connected to a struggle for a maritime, offensive strategy with the aim of securing the fleets of the Warsaw Pact access to the North Sea and the Atlantic in case of war. 

Here, the Soviet navy plays an important role but so do the military command of the Warsaw pact and the military leadership of the GDR. They are linked together in a power struggle where the creation of the Warsaw pact and the integration of the GDR into the Pact added new dynamic elements. 

With an emphasis on the 1960s, it is shown how an occupation of Jutland (and Funen) within the framework of a big land offensive and of the (other) Danish islands in an amphibious operation, with or without the use of nuclear weapons, was treated in detail. 

We do not know if this project was approved by the Soviet general staff and political leadership. However, the main importance of it is seen in the fact that action alternatives were prepared, structured and made available that could have influenced the decision making in a situation of crisis and stress.
