Lineof Battle

Line of Battle. 1. The formation of a fleet of battleships when ready to engage an enemy. 2. The class of vessels designed to participate in a general engagement. This class anciently included vessels of 64 guns and upwards - i.e. those of the first, second, and third rates - and it now includes all armoured sea-going ships that are not classed as "cruisers."
