TACTICS. 816 TACTJLLI. attainable with bodies of men is not possible with ships. There can be no turning with fi.xed pivots, because ships must continue in motion or they cannot be kept under control; nor are sudden halts possible, for a hea-}' ship moving at high speed cannot be stopped in a less distance than several times her length. These and other considerations have led to the general acceptance of certain rules. First. — Movements during battle should be as simple as possible.

Fourth. — Ships of like characteristics should be separately grouped as far as possible ; this is particularly true as regards speed and hardly less so as regards power and arrangement of battery and armor. Fifth.— When approaching the enemy and until in position to deliver attack the fleet must be kept concentrated and in condition to assume any desired formation. The accompanying figures show the various formations commonly used and the method of passing from one to the other. With the excep- Fig. 24. • SQUADRON, PROM THE RIGHT, P^RONT INTO ECHE- LON.'
