The closeness of this approach, however, and the fact that the line of the channel led in at right angles to the entrance, had the disadvantage of obstructing the fire of the broadside wooden vessels, in which the offensive strength of the fleet, outside the monitors, consisted. The guns of those ships, being disposed along the sides, were for the most part able to bear only upon an enemy abreast of them, with a small additional angle of train toward ahead or astern. It was not, therefore, until nearly up with the fort that these numerous cannon would come into play, and exercise that preponderating effect which had driven off the gunners at Forts St. Philip and Jackson. This inconvenience results from the construction of such ships, and can only be overcome by a movement of the helm causing the ship to diverge from her course; a resort which led a witty Frenchman to say that a ship-of-war so situated is like a shark, that can only bite by turning on its back. The remedy, however applicable under certain circumstances and in the case of a single ship, causes delay, and therefore is worse than the evil for a fleet advancing to the attack of forts, where the object must be to close as rapidly as possible. There are, however, on board such vessels a few guns, mounted forward and called chase guns, which, from the rounding of the bows, bear sooner than the others upon the enemy toward whom they are moving. To support these and concentrate from the earliest moment as effective a fire as possible upon the works, Farragut brought his ironclads inside of the wooden vessels, and abreast the four leaders of that column. The heavy guns of the monitors could fire all around the horizon, from right ahead to right astern; and the disposition had the additional great advantage that, in the critical passage inside the torpedo buoys, these all-important vessels would be on the safer side, the wooden ships interposing between them and the sunken dangers, which threatened an injury far more instantaneous and vital than any to be feared from the enemy's shot and shell.
