He returned to Denmark in 1841; producing works based on his Italian studies as well as ones depicting the Danish peasantry. In 1848, following the start of the First Schleswig War, he was given permission to accompany the army to Southern Jutland.

During the Second Schleswig War, despite being sixty-three years old, he was with the army again, at the Battle of Dybbøl and in Sønderborg when the city was under bombardment.
