The Austrians attacked towards the refortified Dannevirke frontally while the Prussian forces struck the Danish fortifications at Mysunde (on the Schlei coast of Schwansen east of Schleswig, trying to bypass the Danevirke by crossing the frozen Schlei inlet, but in six hours could not take the Danish positions, and retreated.

The Austrians had begun to occupy Fahrdorf because there was a gate of the Dannevirke at this point and they wanted to be sure not to hit the flank when advancing against Ober-Selk to be caught.

A Battaltion of the 30th Regiment advanced immediately to the right of the path, while a Jäger battalion under Lieutenant Colonel von Tobias approached from the left.

On the Danish side, a division under Lieutenant General Steinmann that morning consisted of three battalions and 4 guns, which were on the outposts from Fahrdorf around the Noor via Altmühl, Selk to Jagel.

However, Major General Gondrecourt immediately recognized that the village could only be secured by taking Königshügel on the opposite side.

The Danes defended the town fiercely, by using skilled rifle fire and fixed bayonets, in order to push the Austrians back.

The capture of Königshügel was strategically important, as its prominent location provided an insight into the entire Dannevirke position.

Theodor Fontane remembered the Austrian units in the Austro-Prussian War during the Battle of Podol: Podol was occupied by the Poschacher brigade, the so-called“ iron brigade ”(consisting of the Martini and King of Prussia regiments and the 18th Jäger Battalion); it was the same brigade that stormed the Königshügel in the Schleswig war and, by taking away this dominant position, made a major contribution to the conquest of the Danes.By gaining the fore area, it was now possible for the Allies to station heavy artillery.

The enemy has also already been able to establish his artillery.A memorial with the epitaph was erected for the fallen: Your at Ober-Selk, Jagel, on Königsberg and at Wedelspang on III.

May this wreath be wound to the brave companions, Who found their cold grave here in strange earth The good comrade full of high heroism, who bought our victory with their heart's blood.
