"Nymphe" saw action during the Second Schleswig War against Denmark in 1864, and took part in the largest action in the Baltic during the war, the Battle of Jasmund. She and the frigate sortied to attack the Danish blockade, and in the ensuing action, "Nymphe" was heavily engaged by the Danish frigate , and she received around 70 hits, mostly to her rigging, though she was not seriously damaged and casualties were light. The ship was in the process of being recalled to Germany during the Austro-Prussian War in 1866, and as a result, saw no action during the conflict, but she did see battle with French warships during the Franco-Prussian War in 1870. A French squadron of ironclads had anchored off Danzig, and "Nymphe" launched a surprise night attack on the idle vessels, though she inflicted no serious damage on the armored vessels. Her attack nevertheless convinced the French admiral, Édouard Bouët-Willaumez, that his heavy ships were not useful in a close blockade of German ports, and so they left.
