Russian cruiser Oleg
1903 Bogatyr-class cruiser

Oleg (Russian: Олег) was the fourth and final Bogatyr-class protected cruiser built for the Imperial Russian Navy.
Operational history
Oleg was laid down at the Admiralty Shipyards at St. Petersburg on 6 July 1902, launched on 14 August 1903 and commissioned into the Russian Baltic Fleet on 24 June 1904. With the Russo-Japanese War already in progress, she was seconded to the Russian Second Pacific Squadron.
Russo-Japanese War
Under the command of Admiral Oskar Enkvist, Oleg was part of the Russian Second Pacific Squadron, which sailed from the Baltic Sea around the world to relieve the Japanese blockade of the Russian Pacific Fleet at Port Arthur during the Russo-Japanese War. The squadron engaged Japanese Admiral Togo Heihachiro's Combined Fleet at the Battle of Tsushima on 15 May 1905. During the battle, Oleg was damaged, but managed to escape and, together with the cruisers Aurora and Zhemchug reached the protection of the neutral port of Manila, where she was interned until the end of the war.
After returning to the Russian Baltic Fleet, Oleg was refitted and her torpedo nets removed.) On 27 September 1908, she ran aground off Kronstadt. She was refloated on 4 October with assistance from the tugs Forwards, Meteor and Vladimir. She was taken in to Kronstadt for repairs, which were completed in December.
