What was Denmark’s defensive strategy at the Danewirk?

During the German-Danish War of 1864, Denmark’s defensive strategy relied heavily on mounting a frontal defense at the Danewirk, a historic line of earthen fortifications stretching across the neck of Jutland.12

The Danes considered these defenses to be impregnable, having invested significant resources into their repair and strengthening from 1850 onward. However, this strategy failed when Prussian forces threatened to turn the flank of the entire defensive line by crossing the Schlei inlet to the northeast. Faced with this maneuver and being significantly outgunned—particularly by superior Prussian artillery—the Danish army abandoned the Danewirk without a struggle on February 6, 1864.12
