The arrangement of guns in broadside involved anomalies and inconveniences which seem most singular when first noted. A ship in chase of another, for instance, had no guns which threw straight ahead. If it were wished to fire, in order to cripple the fleeing enemy, it was necessary to deflect from the course; and in order to bring most of the guns on one side into play the vessel had to swing round nearly at right angles to the direction of pursuit. This, of course, lost both time and ground. Broadside fire—the distribution of guns in broadside—rests, however, upon an unchangeable condition, which controls now as it did a century ago. Ships then were from three to four times as long as they were broad; the proportion now is, length from four to six times the breadth—or beam, as it is technically called. Therefore, except in small vessels, where the concentration of the whole weight that can be carried in battery gave but one piece effective against a probable target, a full development of fire required the utilization of the long side of the ship rather than of its short cross-section. This is precisely analogous to the necessity that an army has of deploying into line, from any order of march, in order to develop its full musketry fire. The mechanical attainment of the last century did not permit the construction of single guns that would contain the weight of the whole battery of a big ship: but even had it, guns are not wanted bigger than will penetrate their target most effectively. When an ounce of lead will kill a man it is useless to fire a pound. The limit of penetration once reached, it is numbers, not size, that tell: and numbers could be had only by utilizing the broadside. This condition remains operative now; but as modern battle-ships present two or more kinds of target—the heavy armored and that which is light armored, or unprotected—the application of the principle in practice becomes more complicated. Batteries now are necessarily less homogeneous than they once were, because targets vary more. DISAPPEARANCE OF BOW FIRE
