 "Preussischer Adler" and the other Prussian ships remained on the disengaged side of the Austrian frigates, taking shots at the Danish vessels when possible, though they had little success.After "Schwarzenberg" caught fire, Tegetthoff broke off the action and escaped to the neutral waters around Heligoland, where the ships remained until early the next day.During the period off Heligoland, the Prussian vessels sent their doctors to the Austrian frigates to help tend to their wounded.
