General Description. 
These vessels are divided into armoured and protected cruisers, the 
former having side armour from 4 to 5 inches in thickness and having 
their guns protected with about 7 inches of armour. 
The protected cruisers have their sides protected by coffer dams and 
coal bunkers. 
Their guns are unprotected. 
General Idea eor Attack. 
As this class of ship will always try to run past forts at speed, every 
endeavour must be made to injure their hulls. 
At all ranges, use C.P. at their “ vitals” and superstructure, special 
attention being paid to the conning tower.
