You've hit a subject dear to my heart. The Battlecruiser has been a subject I have loved even more than battleships and carriers, I've got tons of books on them.
The Battlecruiser was a failed experiment that only lasted about 10 years, and primarily a British invention, pushed by Lord Jacky Fisher. The idea was to take a battleship design, eliminate much of the armor, and stretch the hull by 100 or more feet, and the result would be essentially a superfast battleship which could dictate the rules of engagement to the other side - if the opponent was more powerful, the battlecruiser can run, if the opponent is less powerful, it could dictate the range of engagement, blasting away with heavy guns and denying the opponent a chance of closing in with torpedoes. As the design necessitated a long, thin hull, built for speed and with battleship-style weaponery, it also resulted in the most beautiful military designs ever.
Having the heavy calibre weapons of battleships tempted admirals to use them in the battle line, which resulted in disaster at Trafalgar. The last battlecruisers (including the Hood) which were then under construction were either cancelled or completed with some major modifications.
The first battlecruiser, the Indomitable, was completed in 1908. The last one was the Hood, in 1918.
