Fire-ships are seen here to have played a very conspicuous part, more so certainly than in the war of 1653, though at both periods they formed an appendage to the fleet. There is on the surface an evident resemblance between the rôle of the fire-ship and the part assigned in modern warfare to the torpedo-cruiser. The terrible character of the attack, the comparative smallness of the vessel making it, and the large demands upon the nerve of the assailant, are the chief points of resemblance; the great points of difference are the comparative certainty with which the modern vessel can be handled, which is partly met by the same advantage in the iron-clad over the old ship-of-the-line, and the instantaneousness of the injury by torpedo, whose attack fails or succeeds at once, whereas that of the fire-ship required time for effecting the object, which in both cases is total destruction of the hostile ship, instead of crippling or otherwise reducing it. An appreciation of the character of fire-ships, of the circumstances under which they attained their greatest usefulness, and of the causes which led to their disappearance, may perhaps help in the decision to which nations must come as to whether the torpedo-cruiser, pure and simple, is a type of weapon destined to survive in fleets. A French officer, who has been examining the records of the French navy, states that the fire-ship first appears, incorporated as an arm of the fleet, in 1636. "Whether specially built for the purpose, or whether altered from other purposes to be fitted for their particular end, they received a special equipment. The command was given to officers not noble, with the grade of captain of fire-ship. Five subordinate officers and twenty-five seamen made up the crew. Easily known by grappling-irons which were always fitted to their yards, the fire-ship saw its rôle growing less in the early years of the eighteenth century. It was finally to disappear from the fleets _whose speed it delayed and whose evolutions were by it complicated_. As the ships-of-war grew larger, their action in concert with fire-ships became daily more difficult. On the other hand, there had already been abandoned the idea of combining them with the fighting-ships to form a few _groups_, _each_ provided with all the means of attack and defence. The formation of the close-hauled line-of-battle, by assigning the fire-ships a place in a second line placed half a league on the side farthest from the enemy, made them more and more unfitted to fulfil their office. The official plan of the battle of Malaga (1704), drawn up immediately after the battle, shows the fire-ship in this position as laid down by Paul Hoste. Finally the use of shells, enabling ships to be set on fire more surely and quickly, and introduced on board at the period of which we are now treating,
