Franz Joseph I of Austria
If Greater Germany was to prevail, the crown would necessarily have to go to Franz Joseph, who had no desire to cede it in the first place to anyone else. On the other hand, if the idea of a smaller Germany won out, the German crown could of course not possibly go the Emperor of Austria, but would naturally be offered to the head of the largest and most powerful German state outside of Austria—the King of Prussia. The contest between the two ideas, quickly developed into a contest between Austria and Prussia. After Prussia decisively won the Seven Weeks War, this question was solved; Austria lost no territories as long as they remained out of German affairs.
Drache-class ironclad
Two years after the ships entered service, Austria joined Prussia in the Second Schleswig War against Denmark. "Drache" and "Salamander" were kept in the Adriatic to defend against a possible Danish attack, which failed to materialize. In 1866, Austria's erstwhile ally Prussia signed an alliance with Italy directed against Austria, beginning the Seven Weeks' War. The Austrian fleet was commanded by Rear Admiral Wilhelm von Tegetthoff, who attacked the Italian fleet as it attempted to capture the island of Lissa in the central Adriatic. In the ensuring Battle of Lissa, both ships were heavily engaged, with "Drache" inflicting fatal damage to the coastal defense ship , setting her on fire and ultimately destroying her. "Drache" did not escape unscathed, however, as she was hit by Italian shells numerous times; she lost her main mast, was temporarily set on fire, and her commander was killed. "Salamander" engaged the leading ships of the Italian line, though neither side inflicted serious damage on the other. Nevertheless, the loss of "Palestro" and the ironclad led the demoralized Italian fleet to disengage and retreat to their base at Ancona.
