Düppeler Schanzen
This Second War of Schleswig of 1864 was presented by invaders to be an implementation of the law of the German Confederation ("Bundesexekution"). After the defeat in the Battle of Dybbøl, the Danes were unable to defend the borders of Schleswig, then had to retreat to Denmark proper, and finally were pushed out of the entire Jutland peninsula. Denmark capitulated and Prussia and Austria took over the administration of Schleswig and Holstein respectively under the Gastein Convention of August 14, 1865. Already in 1864 the Prussian occupying authorities had deposed Bishop Sechmann Boesen.
