Historians' opinions on the outcome of the battle are mixed, with some citing the withdrawal of Tegetthoff's ships, and the greater damage they sustained, as evidence of a tactical victory for Suenson. Other naval historians cite the lifting of the blockade as a strategic victory for the Austrians and Prussians, and others still describe the battle as inconclusive. The Battle of Heligoland was the last naval battle fought by squadrons of wooden ships, and it was also the last time Danish warships fought a major action. "Jylland" is preserved in Ebeltoft, the last surviving wooden-hulled, screw-driven warship.
