The Government had an important project in hand. The Mississippi River was largely in the control of the Confederacy, and was the great highway for transporting her supplies. New Orleans was the richest city of the South, receiving for shipment at this time ninety-two million dollars worth of cotton, and more than twenty-five million dollars worth of sugar yearly. If this city could be captured, and the river controlled by the North, the South would be seriously crippled. But the lower Mississippi was guarded by the strongest forts, Jackson and St. Philip, which mounted one hundred and fifteen guns, and were garrisoned by fifteen hundred men. Above the forts were fifteen vessels of the Confederate fleet, including the ironclad ram, _Manassas_, and just below, a heavy iron chain across the river bound together scores of cypress logs thirty feet long, and four or five feet in diameter, thus forming an immense obstruction. Sharpshooters were stationed all along the banks. Who could be entrusted with such a formidable undertaking as the capture of this stronghold? Who sufficiently daring, skilful, and loyal? Several naval officers were considered, but Gideon Welles, Secretary of the Navy, said, "Farragut is the man." The steam sloop-of-war, _Hartford_, of nineteen hundred tons burden, and two hundred twenty-five feet long, was made ready as his flag-ship. His instructions were, "The certain capture of the city of New Orleans. The Department and the country require of you success.... If successful, you open the way to the sea for the Great West, never again to be closed. The rebellion will be riven in the centre, and the flag, to which you have been so faithful, will recover its supremacy in every State." With a grateful heart that he had been thought fitting for this high place, and believing in his ability to win success, at sixty-one years of age he started on his mission, saying, "If I die in the attempt, it will only be what every officer has to expect. He who dies in doing his duty to his country, and at peace with his God, has played the drama of life to the best advantage." He took with him six sloops-of-war, sixteen gunboats, twenty-one schooners, and five other vessels, forty-eight in all, the fleet carrying over two hundred guns. April 18, 1862, they had all reached their positions and were ready for the struggle. For six days and nights the mortars kept up a constant fire on Fort Jackson, throwing nearly six thousand shells. Many persons were killed, but the fort did not yield. The Confederates sent down the river five fire-rafts, flat-boats filled with dry wood, smeared with tar and turpentine, hoping that these would make havoc among Farragut's ships; but his crews towed them away to shore, or let them drift out to sea.
