Brave Old Salt by Oliver Optic

In order to appreciate the importance of the tremendous action in Mobile Bay, it is necessary to consider that Mobile and Wilmington were the only available ports of the rebels east of the Mississippi. The resources of the Confederacy were exhausted by three years of wasting war, and it was dependent upon foreign supplies for the means of continuing the strife. The earnest attention of the government at Washington, therefore, was directed to the shutting up of these ports.

To form a correct idea of the obstacles to the closing of Mobile Bay, which had been intrusted to Admiral Farragut, it should be remembered that its entrance was guarded by two strongly-built and heavily-armed forts; that the only available channel for large vessels, but three fourths of a mile in width, ran under the guns of Fort Morgan, the stronger of the two forts; that this channel was filled with sunken torpedoes, which, experience had demonstrated, were fatal to any vessels subjected to the explosion; and that the rebels had a fleet of gunboats and iron-clads, which could operate with every advantage against an advancing fleet.
