"Frauenlob" and "Stettin" shortly thereafter encountered the British cruiser and about six destroyers and they opened fire at 09:09. The ships quickly found the range and hit the British ship an estimated 25–35 times, disabling all but one of her guns and inflicting serious damage. One shell detonated a cordite charge and set "Arethusa" on fire. The ship's engine room flooded and her speed fell to . She turned away to starboard in order to escape from the punishing fire, but "Frauenlob" kept up with the badly damaged British cruiser until she disappeared in the fog. In return, "Frauenlob" was hit ten times, but was not seriously damaged; in all, five men were killed and another thirty-two were wounded. After the engagement ended, "Frauenlob" and the torpedo boat took the badly damaged minesweeper under tow and returned her to Heligoland, before proceeding to Wilhelmshaven.
