Petropavlovsk was the lead ship of her class of three pre-dreadnought battleships built for the Imperial Russian Navy during the last decade of the 19th century. Named for the successful Russian defense during the 1854 Siege of Petropavlovsk, the ship was sent to the Far East almost immediately after entering service in 1899. She participated in the suppression of the Boxer Rebellion the next year and served as the flagship of the First Pacific Squadron. Petropavlovsk played a minor role in the Battle of Port Arthur, the Japanese surprise attack on the Russian squadron that opened the Russo-Japanese War, in February 1904. The ship sank on 13 April after striking one or more mines near Port Arthur, in northeast China. Casualties numbered 27 officers and 652 enlisted men, including Vice Admiral Stepan Makarov, the commander of the squadron, and the war artist Vasily Vereshchagin.

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
