Battle of Sankelmark The Battle of Sankelmark ( or Battle of Oeversee ) was a minor battle during the Second Schleswig War . It took place on 6 February 1864 between Sankelmark and Oeversee , on the road between Schleswig and Flensburg , during the Danish retreat from Dannevirke . Background . The Danish army , under General Christian Julius De Meza had taken up position at the defenses of Dannevirke and had managed to hold the Prussians at bay at the Battle of Mysunde on February 2 . With the lack of heavy artillery and judging that the Dannevirke defenses were insufficient for a successful defense , De Meza decided the position was untenable and ordered a withdrawal to preserve the army intact and prevent encirclement . The withdrawal of the Danish Army to Dybbøl began on February 4 . The Danish troops withdrew through the freezing weather . Austrian troops were dispatched in pursuit and in response , the 7th Brigade of the Danish army was ordered to stop the Austrians . Austrian troops reached the Danish rearguard near Sankelmark in the afternoon of February 6 . Battle . The Danish 7th Brigade consisting of the 1st Regiment , made up of soldiers from Copenhagen and the 11th Regiment , made up of soldiers from Vendsyssel was commanded by Colonel Max Müller and had taken up positions on both sides of the road . Around 3 . 30 PM , the battle commenced when Colonel Max Müller ordered the 1st Regiment to attack . The Danish troops launched a fierce bayonet charge and despite the numerical advantage of the Austrian troops , the Danish troops managed to halt the Austrians . Fierce fighting , including hand - to - hand combat , followed and lasted for hours without either side gaining the decisive upper hand . The battle ended around 5 PM in the afternoon , when the sun began to set . The 7th Brigade then withdrew and linked up with the rest of the Danish army . Aftermath . With the successful rearguard action by the 7th Brigade , the Danish army reached the safety of the redoubts at Dybbøl . Despite heavy losses , the Danish soldiers had performed well and the Austrian pursuers were halted . The successful withdrawal of the Danish army was , however , met with anger and disbelief from the Danish public and politicians . Following the victory in the First Schleswig War , a sense of military superiority had spread in Denmark and Dannevirke , considered the historical border between Denmark and the German states , was considered a sacred national symbol and a formidable defensive line . In reality the defenses of Dannevirke was simply not sufficient for a successful defense . Unfortunately , only the army recognized this , while politicians and the public demanded a defense of this national symbol . Few considered and acknowledged that De Meza had actually saved the army from eventual certain destruction by withdrawing and that the army had withdrawn without significant casualties . The withdrawal was a success because the Danish army remained intact . De Meza was eventually sacked by the Minister of War and the Danish army lost one of its most capable and resourceful officers at a critical stage of the war . The perceived loss of face also meant that a later withdrawal from defenses at Dybbøl was almost impossible due to public and political pressure . This became a factor in the later Danish defeat at the Battle of Dybbøl .
