William Wood, Flag and Fleet: How the British Navy Won the Freedom of the Seas
“ The chief kinds of fighting craft in the Grand Fleet can be told off on the fingers of one hand. First, the Battleships and Battle Cruisers.

The battle cruiser is faster than the battleship, and therefore not so strong; because to be faster you must thin your heavy armour to let you put in bigger engines. All the ships of this first kind were either Dreadnoughts or super-Dreadnoughts ”
