The action of 10 May 1915, or Battle of the Bosporus, was a naval encounter between the Russian pre-dreadnought squadron and the Ottoman battlecruiser Yavuz Sultan Selim in the Black Sea, north of the Bosporus. After a brief exchange of fire the Ottomans withdrew. The battle took place during the main operation of the Black Sea Fleet aimed at shelling the Bosporus fortifications. The action of the battlecruiser led to the interruption of the operation, but it did not manage to inflict significant damage to the Russian fleet, suffering only minor damage itself.
