Cyril Field, The British Navy Book
“ In like manner a naval brigade is either, in the case of a single ship, a landing-force composed of her bluejackets and marines brigaded together, or, in the case of a fleet or squadron, of its various ships' companies. In a fleet of any size the naval brigade available for landing—if there was no chance of an attack by sea—might amount to two or three battalions formed out of seamen and stokers, and one of marines. It has frequently fallen to the lot of naval brigades to carry on a small campaign "on their own", but very often a naval brigade has been attached to an army on active service. ”
