The Imperial Russian steam frigate Alexander Nevsky is shipwrecked off Jutland while carrying Grand Duke Alexei Alexandrovich of Russia.

Alexander Nevsky was a large screw frigate of the Russian Imperial Navy. The ship was designed as part of a challenge being offered by the Russian Empire to the Royal Navy, but was lost in a shipwreck in 1868 while Grand Duke Alexei, son of Tsar Alexander II, was aboard.
