But the cup of his misery was not yet full. The greatest fleet the United States Navy had gathered, was circling the mouth of the Mississippi with its guns pointing toward New Orleans. Gideon Welles had selected for command of this important enterprise the man of destiny, Davis Glasgow Farragut, a Southerner whose loyalty to the Union had never been questioned.
Eighty-two ships answered Farragut's orders in his West Gulf squadron at their rendezvous. His ships were wood, but no braver men ever walked the decks of a floating battery.
In March he managed to crawl across the bar and push his fleet into the mouth of the Mississippi. The Colorado was too deep and was left outside. The Pensacola and the Mississippi he succeeded in dragging through the mud.
His ships inside, the Commander ordered them stripped for the death grapple.
New Orleans had been from the first considered absolutely impregnable to attack from the sea. Forts Jackson and St. Phillip, twenty miles below the city, were each fortifications of the first rank mounting powerful guns which swept the narrow channel of the river from shore to shore.
The use of steam, however, in naval warfare was as yet an untried element of force in the attacking fleet against shore batteries. That steam in wooden vessels could overcome the enormous advantage of the solidity and power of shore guns had been considered preposterous by military experts.
Jefferson Davis had utilized every shipbuilder in New Orleans to hastily construct the beginnings of a Southern navy. Two powerful iron-clad gunboats, Louisiana and Mississippi, were under way but not ready for service. Eight small vessels had been bought and armed.
To secure the city against the possibility of any fleet passing the forts at night or through fog, the channel of the river between Forts Jackson and St. Phillip was securely closed. Eleven dismasted schooners were moored in line across the river and secured by six heavy chains. These chains formed an unbroken obstruction from shore to shore.
This raft was placed immediately below the forts.
There was no serious alarm in the city on the appearance of the fleet in the mouth of the river. For months they had been cruising about the Gulf of Mexico without apparent decision.
