ATTACK NO. II. 
AGAINST MEDIUM IRONCLADS.—SIGNAL—TWO. 
General Description. 
Ships of this class are generally fairly heavily armoured, their belt 
armour being usually composed of steel or compound plates, varying 
from 14*8 to 17*2 inches in thickness (equivalent to from 18‘5 to 21*5 
inches W.I.) and carry their heavy guns in barbettes protected by 
compound armour, varying in thickness from 9’5 to 14 inches (equiva¬ 
lent to from 11’2 to 17*5 inches W.I.). 
With the exception of the belt and barbettes, the remainder of the 
hull is open to “ shell attack.” 
General Idea for Attack. 
The unarmoured portions of these vessels should be the principal 
object of attack beyond 2000 yards. 
At ranges below 2000 yards, the heavy B.L. guns may attack the 
armour. 
The Q.F. and moveable armament being utilised to keep down the 
fire of the heavy guns and tops.
