The Schleswig-Holsteinians were not able to completely cut off the town, but the threat that that could still happen prompted Lunding to urge his superiors to launch an attack soon.

[1] Danish commanders agreed that a major attack would be made north of the town, with General Olaf Rye's 5th Brigade tasked with taking the strongest redoubt, the Treldeskansen; whilst diversionary landings by two fleets each of 22 ships (each had 1 steamer, 4 gunboats, 5 transports and 12 sailing ships) would be launched north and south of Fredericia to draw away enemy troops.

A dense fog shrouded the Danish soldiers as they moved, and straw placed over the streets and the noise of the wind reduced the sound they were making as they traversed through Fredericia, resulting in their deployment not being detected.

The third and fourth Schleswig-Holsteinian redoubts, as well as a nearby mortar battery, were attacked by General De Meza's 'Avantgarden' (Vanguard) detachment.

[1] The fighting at the Treldeskansen had turned into a stalemate, but the reinforcement of the Danish troops with the 8th Battalion from Moltke's Brigade and the half-battery 'Tillisch' led to the capture of the redoubt, along with 300 prisoners, by 04:00.

The first Danish attack against the battalion was repulsed, and whilst they were preparing to launch another one, the sun rose and allowed Bonin to see that the Schleswig-Holsteinian 1st Brigade was retreating.

[1] De Meza followed the retreating Schleswig-Holsteins with the Danish advance guard towards Egum and Stallerup, and blocked the withdrawal of the 1st Brigade, capturing 750 prisoners as a result.

To the east of Stoutrup, the Schleswig-Holsteinian artillery park was located, with 100 wagons, a couple of guns and thousands of cannonballs and grenades captured.

[1] As a result of the battle, a cease-fire was implemented between the combatants in the First Schleswig War, and all German troops had left Denmark by 25 August.
