Early in March the raft, formed of great cypress trees, forty feet long and fifty inches through, laid lengthwise in the river about three feet apart, anchored by heavy chains and strengthened by massive cross-timbers, had been partly carried away by the flood. To make good the damage, a number of large schooners had then been anchored in the gap. On the morning of the 21st of April this formidable obstruction was cleverly and in a most gallant manner broken through by the fleet.

On the night of the 23d of April, Farragut moved to the attack. His fleet, organized in three divisions of eight, three, and six vessels respectively, was formed in line ahead. The first division was led by Captain Bailey, in the Cayuga, followed by the Pensacola, Mississippi, Oneida, Varuna, Katahdin, Kineo, and Wissahickon; the second division followed, composed of Farragut's flag-ship, the Hartford, Commander Richard Wainwright, the Brooklyn, and the Richmond; while the third division, forming the rear of the column, was led by Captain Bell, in the Sciota, followed by the Iroquois, Kennebec, Pinola, Itasca, and Winona.

At half-past two o'clock on the morning of the 24th of April the whole fleet was under way; a quarter of an hour later the batteries of Forts Jackson and St. Philip opened simultaneously upon the Cayuga. It was some time before the navy could reply, but soon every gun was in action. Beset by perils on every hand, the fleet pressed steadily up the river. The Confederate boats were destroyed, the fire-rafts were overcome, the gunners of the forts were driven from their guns, and when the sun rose Farragut was above the forts with the whole of his fleet, except the Itasca, Winona, and Kennebec, which put back disabled, and the Varuna, sunk by the Confederate gunboats. The next afternoon, having made short work of Chalmette, Farragut anchored off New Orleans, and held the town at his mercy.

The casualties were 37 killed and 147 wounded, in all 184. The
Confederate loss was 50, 11 killed and 39 wounded. The Louisiana,
McCrea
, and Defiance, sole survivors of the Confederate fleet,
escaping comparatively unhurt, took refuge under the walls of Fort
St. Philip.

Leaving Phelps, with the 30th Massachusetts and 12th Connecticut and Manning's 4th Massachusetts battery, at the head of the passes, in order to be prepared to occupy the works immediately on their surrender, Butler hastened with the rest of his force to Sable Island in the rear of Fort St. Philip. When the transports came to anchor on the morning of the 26th, the Confederate flags on Forts St. Philip and Jackson were plainly visible to the men on board, while these, in their turn, were seen from the forts. Here the troops received the news of Farragut's arrival at New Orleans. On the morning of the 28th they saw the Confederate ram Louisiana blown up while floating past the forts, and on the same day Jones landed with the 26th Massachusetts and Paine with two companies of the 4th Wisconsin and a detachment of the 21st Indiana, to work their way through a small canal to Quarantine, six miles above Fort St. Philip, for the purpose of seizing the narrow strip by which the garrison must escape, if at all. This was only accomplished by a long and tiresome transport in boats, and finally by wading. However, at half-past two on the afternoon of the 28th April, the Confederate flags over Forts Jackson and St. Philip were observed to disappear; the national ensign floated in their stead; and soon it became known that Duncan had surrendered to Porter.

Porter immediately took possession and held it until Phelps came up the river to relieve him. Then Major Whittemore, of the 30th Massachusetts, with about two hundred men of his regiment, landed and took command at Fort St. Philip, while Manning occupied Fort Jackson. Almost simultaneously the frigate Mississippi came down the river, bringing Jones with the news that his regiment was at Quarantine, holding both banks of the river, and thus effectually sealing the last avenue of escape; for at this time the levee formed the only pathway. On the 29th Phelps put Deming in command of Fort Jackson, intending to leave his regiment, the 12th Connecticut, in garrison there, and to place Dudley, with the 30th Massachusetts, at Fort St. Philip; but before this arrangement could be carried out, orders came from Butler, designating the 26th Massachusetts as the garrison of the two forts, with Jones in command. Phelps, with his force, was directed to New Orleans.

On the 1st of May Butler landed at New Orleans and took military possession of the city. Simultaneously, at five o'clock in the afternoon, the 31st Massachusetts with a section of Everett's 6th Massachusetts battery, and six companies of the 4th Wisconsin, under Paine, disembarked and marched up the broad levee to the familiar airs that announced the joint coming of "Yankee Doodle" and of "Picayune Butler."

The outlying defences on both banks of the river and on the lakes were abandoned by the Confederates without a struggle. Forts Pike and Wood, on Lake Pontchartrain, were garrisoned by detachments from the 7th Vermont and 8th New Hampshire regiments. The 21st Indiana landed at Algiers, and marching to Brashear, eighty miles distant on Berwick Bay, took possession of the New Orleans and Opelousas railway. New Orleans itself was occupied by the 30th and 31st Massachusetts, the 4th Wisconsin and 6th Michigan, 9th and 12th Connecticut, 4th and 6th Massachusetts batteries, 2d Vermont battery, and Troops A and B of the Massachusetts cavalry. At Farragut's approach Lovell, seeing that further resistance was useless, abandoned New Orleans to its fate and withdrew to Camp Moore, distant seventy-eight miles, on the line of the Jackson railway.

CHAPTER II. THE FIRST ATTEMPT ON VICKSBURG.

With the capture of New Orleans the first and vital object of the expedition had been accomplished. The occupation of Baton Rouge by a combined land and naval force was the next point indicated in McClellan's orders to Butler. Then he was to endeavor to open communication with the northern column coming down the Mississippi. McClellan was no longer General-in-chief; but this part of his plan represented the settled views of the government.
