[1] To remove the threat to his right flank after the battle at Nybøl, General Wrangel decided to try a new attack on the Danish forces at Sundeved.

The break of the attack meant that there was time to put the Danish reserves from Als into the battle, and thereby strengthen the Dybbøl position.

A Prussian eyewitness wrote about the attack: "Like a blood-red cloud, threatening with destruction, the Danish forces tumbled down over the bank".

However, the Danes did not follow up the victory, as it was expected that the Prussians would attack again the next day with their unused reserves - this would mean a clear German superiority.

The advance of the Danish army was interrupted, which gave the Germans the opportunity to retreat in good order.
