"Nymphe" saw action during the Second Schleswig War against Denmark in 1864 at the Battle of Jasmund. She was heavily engaged by a Danish frigate in the battle; she received around 70 hits, mostly to her rigging, though she was not seriously damaged. The ship, which had been on a cruise in the Mediterranean Sea, 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. 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 French ships. Her attack nevertheless convinced the French admiral that his heavy ships were not useful in a close blockade of German ports, and so they left.
