Brigadier-General Neill, who was assigned to the command of the Third brigade, was active in encouraging his men to provide good quarters, and in furnishing every facility in his power to make them comfortable. The general was a portly gentleman, with light red hair and whiskers, and a small blue eye, ceremonious in his style, and a perfect pattern of courtliness. He had, at West Point, won the appellation of "Beau Neill," a title which never left him. He was a good commander in camp. He originated the brigade dress parade that winter, often calling out the brigade on fine evenings, and substituting the brigade for the regimental parade. The custom was at length adopted in many brigades in the army of the Potomac; but few gave credit for the improved parade to the originator of it.

The second failure of General Burnside rendered his removal from the command of the army a thing to be expected; and no one was surprised when the order came relieving him, and assigning General Hooker to the command. It must be confessed that our failure at Bank's Ford had done much to demoralize the army and destroy the confidence in the commanding general so absolutely necessary to success. On our way back from Bank's Ford, as we passed Fredericksburgh, we saw huge placards posted up by the rebels with taunting inscriptions, such as "Burnside stuck in the mud," printed in conspicuous letters. The men caught up the words, and "Burnside stuck in the mud" passed from one end of the disordered column to the other. When we had failed at Fredericksburgh, the men were as willing as ever to try again under the same commander. They believed him to be at least earnest and brave. They knew that he was noble and self-sacrificing. In the noble letter to General Halleck, in which he assumed all the responsibility for the failure at Fredericksburgh, they found renewed assurance that he had all the qualities of a true soldier—bravery, integrity and true manhood; but an army must have success, or it cannot long repose confidence in the general. So, while the Army of the Potomac regarded General Burnside with great respect, it gladly welcomed the advent of "Fighting Joe Hooker" to the command.

General Hooker had fairly won the title of "Fighting Joe" at the slaughter of Williamsburgh, where, almost single-handed with his division, he had stemmed the tide of battle for hours, until reinforced by Kearney, and then, with the help of that hero, had held the whole rebel army until it was outflanked by our Second division.

In all the battles of the Peninsula he had been conspicuous, and at South Mountain and Antietam his fighting propensities were exhibited in more than their wonted splendor. In person he was of large stature, with fine features, brilliant eye, his side whiskers and ruddy countenance giving a more youthful appearance than his light gray hair would indicate. His gleaming eye told of the spirit which animated the man, and his determined air betokened the persistent and fearless soldier. In battle or on review he rode a magnificent milk white steed, a powerful animal and of extraordinary fleetness. Mounted on this superb war horse, he was the most conspicuous, as he was always one of the handsomest men in the army.

The energy of the new commander soon began to be manifested in the reconstruction and reorganization of the whole army. The first step in the progress of reconstruction, was the revocation of the order making three grand divisions of the army. By the abolition of the grand divisions, Generals Sumner and Franklin were relieved from their commands; and the corps commanders, no longer subject to intermediate commanders, were again directly responsible to the general-in-chief of the army. Doubtless General Hooker had seen that the creation of these grand divisions had much to do with the failures of General Burnside.

The cavalry next engaged the attention of the general. The whole force was thoroughly reorganized and put in an efficient condition, under command of Major-General Stoneman. Hereafter, men were not to ask, "Who ever saw a dead cavalryman?" To General Hooker, the cavalry of the Army of the Potomac owes its efficiency and the glorious record it from that time made for itself.

The superiority of the rebel cavalry, in the early part of the war, was generally attributed to the supposed fact that the young men of the south were so much better horsemen than those of the north. In reality, this had little, if anything, to do with it. It is even very doubtful if there was any difference in favor of the superior horsemanship of the southern cavalry. Their strength lay in their union. The rebel cavalry was organized from the beginning; ours was an incoherent mass of men, having no proper relations or dependencies within itself. From the day that it became organized, the superiority of the rebel cavalry passed away forever. We had always better horses, and our men were certainly never inferior to the rebels. All that was needed was the proper combination of action; and, as soon as this was secured, our cavalry became the finest in the world.

The business departments were also thoroughly renovated. The changes in the medical, quartermasters' and commissary departments were such as to bring each to a standard of perfection, which had never before been reached by those departments of any army in the field. No army had ever been provisioned as was ours that winter. Soft bread, potatoes, beets, carrots, onions, fresh beef, flour, sugar and coffee, constituted the regular rations of the men, and facilities were afforded for procuring luxuries not in the regular supply.

The medical department became so thoroughly systematized, that wounded and sick men were cared for better than they had ever been in an army before. This radical change had commenced under General Burnside; but was perfected under General Hooker, by the efficient and earnest medical director of the army, Dr. Letterman; to whom belongs the honor of bringing about this most desirable change.

By the new system, the surgeons were enabled to accomplish a far greater amount of work, and in much better order than under the old; and the wounded were better and more quickly cared for. By this system the hospital of the division was the unit. From the division, a medical officer of good executive ability was selected, to whom was assigned the general oversight of the hospital. One or more surgeons of well known skill and experience were detailed from the medical force of the division, who were known as "operating surgeons;" to each of whom was assigned three assistants, also known to be skillful men, who were either surgeons or assistant surgeons. To the operating surgeons all cases requiring surgical operations were brought, and thus the wounded men had the benefit of the very best talent and experience in the division, in the decision of the question whether he should be submitted to the use of the knife, and in the performance of the operation in case one was required. It was a mistaken impression among those at home, that each medical officer was the operating surgeon for his own men. Only about one in fifteen of the medical officers was intrusted with operations.
