The work of chartering the immense fleet required to transport this force, with its material of all kinds, was confided by the government to Cornelius Vanderbilt, possibly in recognition of his recent princely gift to the nation of the finest steamship of his fleet, bearing his own name. This service Vanderbilt performed with his usual vigor, "laying hands," as he said, "upon every thing that could float or steam," including, it must be added, more than one vessel to which it would have been rash to ascribe either of these qualities.
Before the embarkation each vessel was carefully inspected by a board of officers, usually composed of the inspector-general or an officer of his department, an experienced quartermaster, and an officer of rank and intelligence, who was himself to sail on the vessel. This last was a new, but, as soon appeared, a very necessary precaution. When every thing was nearly ready the embarkation began at New York, and as each vessel was loaded she was sent to sea with sealed orders directing her master and the commanding officer of the troops to make the best of their way to Ship Island, and there await the further instructions of the general commanding. Ship Island was chosen for the place of meeting because of the great draught of water of some of the vessels. At the same time Emory's force, embarking at Hampton Roads, set out under convoy of the man-of-war Augusta, Commander E. G. Parrott, for the same destination with similar orders.
For three months the Florida had lain at anchor in the harbor at Mobile, only waiting for a good opportunity to enter upon her historic career of destruction. Since the 20th of August the Alabama was known to have been scourging our commerce in the North Atlantic from the Azores to the Antilles. On the 5th of December she took a prize off the northern coast of San Domingo. Relying on the information with which he was freely furnished, Semmes expected to find the expedition off Galveston about the middle of January. In the dead of night, "after the midwatch was set and all was quiet," he meant, in the words of his executive officer,(1) slowly to approach the transports, "steam among them with both batteries in action, pouring in a continuous discharge of shell, and sink them as we went." Fortunately Semmes's information, though profuse and precise, was not quite accurate, for it brought him off Galveston on the 13th of January: the wrong port, a month too late. What might have happened is shown by the ease with which he then destroyed the Hatteras.
To guard against these dangers, it had been the wish of the government, and was a part of the original plan, that the transports sailing from New York should be formed in a single fleet and proceed, under strong convoy, to its destination. However, it soon became evident that as the rate of sailing of a fleet is governed by that of its slowest ship, the expedition, thus organized, would be forced to crawl along the coast at a speed hardly greater than five miles an hour. This would not only have exposed three ships out of five, and five regiments out of six, for at least twice the necessary time to the perils of the sea, increased by having to follow an inshore track at this inclement season; it would not only have introduced chances of detention and risks of collision and of separation, but the peril from the Alabama would have been augmented in far greater degree than the security afforded by any naval force the government could just then spare. Therefore, the slow ships were loaded and sent off first and the faster ones kept back to the last; then, each making the best of its way to Ship Island, nearly all came in together. Thus, when the North Star, bearing the flag of the commanding general and sailing from New York on the 4th of December, arrived in the early morning of the 13th at Ship Island, nearly the whole fleet lay at anchor or in the offing; and as soon as a hasty inspection could be completed and fresh orders given, the expedition got under way for New Orleans. The larger vessels, however, like the Atlantic, Baltic, and Ericsson being unable to cross the bar, lay at anchor at Ship Island until they could be lightened.
Truly grand as was the spectacle afforded by the black hulls and white sails of this great concourse of ships at anchor, in the broad roadstead, yet a grander sight still was reserved for the next day, a lovely Sunday, as all these steamers in line ahead, the North Star leading, flags flying, bands playing, the decks blue with the soldiers of the Union, majestically made their way up the Mississippi. Most of those on board looked for the first time, with mingled emotions, over the pleasant lowlands of Louisiana, and all were amused at the mad antics of the pageant-loving negroes, crowding and capering on the levee as plantation after plantation was passed. So closely had the secret been kept that, until the transports got under way from Ship Island for the purpose, probably not more than three or four officers, if so many, of all the force really knew its destination. Nor was it until the two generals met at New Orleans that Butler learned that Banks was to relieve him.
On the 15th of December Banks took the command of the Department of the Gulf, although the formal orders were not issued until the 17th. The officers of the department, as well as of the personal staff of General Butler, were relieved from duty and permitted to accompany him to the North. The new staff of the department included Lieutenant-Colonel Richard B. Irwin, Assistant Adjutant-General; Lieutenant-Colonel William S. Abert, Assistant Inspector-General; Major G. Norman Lieber, Judge-Advocate; Colonel Samuel B. Holabird, Chief Quartermaster; Colonel Edward G. Beckwith, Chief Commissary of Subsistence; Surgeon Richard H. Alexander, Medical Director; Major David C. Houston, Chief Engineer; Captain Henry L. Abbot, Chief of Topographical Engineers; First-Lieutenant Richard M. Hill, Chief of Ordnance; Captain Richard Arnold, Chief of Artillery; Captain William W. Rowley, Chief Signal Officer.
Banks's orders from the government were to go up the Mississippi and open the river, in co-operation with McClernand's expedition against Vicksburg. "As the ranking general of the Southwest," Halleck's orders proceeded, "you are authorized to assume control of any military forces from the upper Mississippi which may come within your command. The line of the division between your department and that of Major-General Grant is, therefore, left undecided for the present, and you will exercise superior authority as far north as you may ascend the river. The President regards the opening of the Mississippi river as the first and most important of all our military and naval operations, and it is hoped that you will not lose a moment in accomplishing it."
Immediately on assuming command Banks ordered Grover to take all the troops that were in condition for service at once to Baton Rouge, under the protection of the fleet, and there disembark and go into camp. Augur was specially charged with the arrangements for the despatch of the troops from New Orleans. Before starting they were carefully inspected, and all that were found to be affected with disease of a contagious or infectious character were sent ashore and isolated.
On the morning of the 16th the advance of Grover's expedition got under way, under convoy of a detachment of Farragut's fleet, led by Alden in the Richmond. Grover took with him about 4,500 men, but when all were assembled at Baton Rouge there were twelve regiments, three batteries, and two troops of cavalry. The Confederates, who were in very small force, promptly evacuated Baton Rouge, and Grover landed and occupied the place on the 17th of December. After sending off the last of the troops, Augur went up and took command. The lines constructed by Paine in August were occupied and strengthened, and all arrangements promptly made for the defence in view of an attack, such as might not unnaturally be looked for from Port Hudson, whose garrison then numbered more than 12,000 effectives. The two places are but a long day's march apart. Since the occupation in August, the Confederate forces at Port Hudson had been commanded by Brigadier-General William N. R. Beall. On the 28th of December, however, he was relieved by Major-General Frank Gardner, who retained the command thenceforward until the end. While the war lasted, Baton Rouge continued to be held by the Union forces without opposition or even serious menace.
An attempt to occupy Galveston was less fortunate. This movement was ordered by Banks a few days after his arrival at New Orleans, apparently under the pressure of continued importunity from Andrew J. Hamilton, and in furtherance of the policy that had led the government to send him with the expedition, nominally as a brigadier-general, but under a special commission from the President that named him as military governor of Texas. On the 21st of December, three companies, D, G, and I, of the 42d Massachusetts, under Colonel Isaac S. Burrell, were sent from New Orleans without disembarking from the little Saxon, on which they had made the journey from New York. With them went Holcomb's 2d Vermont battery, leaving their horses to follow ten days later on the Cambria, with the horses and men of troops A and B of the Texas cavalry. Protected by the flotilla under Commander W. B. Renshaw, comprising his own vessel, the Westfield, the gunboats Harriet Lane, Commander J. M. Wainwright; Clifton, Commander Richard L. Law; Owasco, Lieutenant Henry Wilson; and Sachem, Acting-Master Amos Johnson; and the schooner Corypheus, Acting-Master Spears, Burrell landed unopposed at Kuhn's Wharf on the 24th, and took nominal possession of the town in accordance with his instructions. These were indeed rather vague, as befitted the shadowy nature of the objects to be accomplished. "The situation of the people of Galveston," wrote General Banks, "makes it expedient to send a small force there for the purpose of their protection, and also to afford such facilities as may be possible for recruiting soldiers for the military service of the United States." Burrell was cautioned not to involve himself in such difficulty as to endanger the safety of his command, and it was rather broadly hinted that he was not to take orders from General Hamilton. In reality, Burrell's small force occupied only the long wharf, protected by barricades at the shore end, and seaward by the thirty-two guns of the fleet, lying at anchor within 300 yards.
