The Union fleet anchored for the day at quarantine, five miles above the forts. The following morning, leaving the Kineo and Wissahickon to protect, if necessary, the landing of General Butler's troops, they got under way again in the original order of two columns, not, however, very strictly observed, and went on up the river. As they advanced, burning ships and steamers were passed, evidences of the panic which had seized the city, whose confidence had been undisturbed up to the moment of the successful passage of the forts. Four miles below New Orleans, the Chalmette and McGehee batteries were encountered, mounting five and nine guns. The Cayuga, still leading and steaming too rapidly ahead, underwent their fire for some time unsupported by her consorts, the Hartford approaching at full speed under a raking fire, to which she could only reply with two bow guns. When her broadside came to bear, she slowed down, porting her helm; then having fired, before she could reload, the Brooklyn, compelled to pass or run into her, sheered inside, between her and the works. The successive broadsides of these two heavy ships drove the enemy from their guns. At about the same moment the Pensacola engaged the batteries on the east bank, and the other vessels coming up in rapid succession, the works were quickly silenced. The attack of the fleet upon the forts and its successful passage has been fitly called the battle of New Orleans, for the fate of the city was there decided. Enclosed between the swamps and the Mississippi, its only outlet by land was by a narrow neck, in parts not over three-quarters of a mile wide, running close by the river, which was at this time full to the tops of the levees, so that the guns of the fleet commanded both the narrow exit and the streets of the city. Even had there been the means of defence, there was not food for more than a few days. At noon of the 25th, the fleet anchored before the city, where everything was in confusion. Up and down the levee coal, cotton, steamboats, ships, were ablaze, and it was not without trouble that the fleet avoided sharing the calamity. Among the shipping thus destroyed was the Mississippi, an ironclad much more powerful than the Louisiana. She was nearing completion, and had been launched six days, when Farragut came before the city. His rapid movements and the neglect of those in charge to provide tow-boats stopped her from being taken to the Yazoo, where she might yet have been an ugly foe for the fleet. This and the fate of the Louisiana are striking instances of the value of promptness in war. Nor was this the only fruit snatched by Farragut's quickness. There is very strong reason to believe that the fall of New Orleans nipped the purpose of the French emperor, who had held out hopes of recognizing the Confederacy and even of declaring that he would not respect the blockade if the city held out.
