When the interview with the Secretary was over, I proceeded with General Halleck to the White House to pay my respects to the President. Mr. Lincoln received me very cordially, offering both his hands, and saying that he hoped I would fulfill the expectations of General Grant in the new command I was about to undertake, adding that thus far the cavalry of the Army of the Potomac had not done all it might have done, and wound up our short conversation by quoting that stale interrogation so prevalent during the early years of the war, "Who ever saw a dead cavalryman?" His manner did not impress me, however, that in asking the question he had meant anything beyond a jest, and I parted from the President convinced that he did not believe all that the query implied.
After taking leave I separated from General Halleck, and on returning to my hotel found there an order from the War Department assigning me to the command of the Cavalry Corps, Army of the Potomac. The next morning, April 5, as I took the cars for the headquarters of the Army of the Potomac, General Grant, who had returned to Washington the previous night from a visit to his family, came aboard the train on his way to Culpeper Court House, and on the journey down I learned among other things that he had wisely determined to continue personally in the field, associating himself with General Meade's army; where he could supervise its movements directly, and at the same time escape the annoyances which, should he remain in Washington, would surely arise from solicitude for the safety of the Capital while the campaign was in progress. When we reached Brandy Station, I left the train and reported to General Meade, who told me that the headquarters of the Cavalry Corps were some distance back from the Station, and indicated the general locations of the different divisions of the corps, also giving me, in the short time I remained with him, much information regarding their composition.
I reached the Cavalry Corps headquarters on the evening of April 5, 1864, and the next morning issued orders assuming command. General Pleasonton had but recently been relieved, and many of his staff-officers were still on duty at the headquarters awaiting the arrival of the permanent commander. I resolved to retain the most of these officers on my staff, and although they were all unknown to me when I decided on this course, yet I never had reason to regret it, nor to question the selections made by my predecessor.
The corps consisted of three cavalry divisions and twelve batteries of horse artillery. Brigadier-General A. T. A. Torbert was in command of the First Division, which was composed of three brigades; Brigadier-General D. McM. Gregg, of the Second, consisting of two brigades; and Brigadier-General J. H. Wilson was afterward assigned to command the Third, also comprising two brigades: Captain Robinson, a veteran soldier of the Mexican war, was chief of artillery, and as such had a general supervision of that arm, though the batteries, either as units or in sections, were assigned to the different divisions in campaign.
Each one of my division commanders was a soldier by profession. Torbert graduated from the Military Academy in 1855, and was commissioned in the infantry, in which arm he saw much service on the frontier, in Florida, and on the Utah expedition. At the beginning of hostilities in April, 1861, he was made a colonel of New Jersey volunteers, and from that position was promoted in the fall of 1862 to be a brigadier-general, thereafter commanding a brigade of infantry in the Army of the Potomac till, in the redistribution of generals, after Grant came to the East, he was assigned to the First Cavalry Division.
Gregg graduated in 1855 also, and was appointed to the First Dragoons, with which regiment, up to the breaking out of the war, he saw frontier service extending from Fort Union, New Mexico, through to the Pacific coast, and up into Oregon and Washington Territories, where I knew him slightly. In the fall of 1861 he became colonel of the Eighth Pennsylvania Cavalry, and a year later was made a brigadier-general. He then succeeded to the command of a division of cavalry, and continued in that position till the close of his service, at times temporarily commanding the Cavalry Corps. He was the only division commander I had whose experience had been almost exclusively derived from the cavalry arm.
Wilson graduated in 1860 in the Topographical Engineers, and was first assigned to duty in Oregon, where he remained till July, 1861. In the fall of that year his active service in the war began, and he rose from one position to another, in the East and West, till, while on General Grant's staff, he was made a brigadier-general in the fall of 1863 in reward for services performed during the Vicksburg campaign and for engineer duty at Chattanooga preceding the battle of Missionary Ridge. At my request he was selected to command the Third Division. General Grant thought highly of him, and, expecting much from his active mental and physical ability, readily assented to assign him in place of General Kilpatrick. The only other general officers in the corps were Brigadier-General Wesley Merritt, Brigadier-General George A. Custer, and Brigadier-General Henry E. Davies, each commanding a brigade.
In a few days after my arrival at Brandy Station I reviewed my new command, which consisted of about twelve thousand officers and men, with the same number of horses in passable trim. Many of the general officers of the army were present at the review, among them Generals Meade, Hancock, and Sedgwick. Sedgwick being an old dragoon, came to renew his former associations with mounted troops, and to encourage me, as he jestingly said, because of the traditional prejudices the cavalrymen were supposed to hold against being commanded by an infantry officer. The corps presented a fine appearance at the review, and so far as the health and equipment of the men were concerned the showing was good and satisfactory; but the horses were thin and very much worn down by excessive and, it seemed to me, unnecessary picket duty, for the cavalry picket-line almost completely encircled the infantry and artillery camps of the army, covering a distance, on a continuous line, of nearly sixty miles, with hardly a mounted Confederate confronting it at any point. From the very beginning of the war the enemy had shown more wisdom respecting his cavalry than we. Instead of wasting its strength by a policy of disintegration he, at an early day, had organized his mounted force into compact masses, and plainly made it a favorite; and, as usual, he was now husbanding the strength of his horses by keeping them to the rear, so that in the spring he could bring them out in good condition for the impending campaign.
Before and at the review I took in this situation, and determined to remedy it if possible; so in due time I sought an interview with General Meade and informed him that, as the effectiveness of my command rested mainly on the strength of its horses, I thought the duty it was then performing was both burdensome and wasteful. I also gave him my idea as to what the cavalry should do, the main purport of which was that it ought to be kept concentrated to fight the enemy's cavalry. Heretofore, the commander of the Cavalry Corps had been, virtually, but an adjunct at army headquarters—a sort of chief of cavalry—and my proposition seemed to stagger General Meade not a little. I knew that it would be difficult to overcome the recognized custom of using the cavalry for the protection of trains and the establishment of cordons around the infantry corps, and so far subordinating its operations to the movements of the main army that in name only was it a corps at all, but still I thought it my duty to try.
At first General Meade would hardly listen to my proposition, for he was filled with the prejudices that, from the beginning of the war, had pervaded the army regarding the importance and usefulness of cavalry, General Scott then predicting that the contest would be settled by artillery, and thereafter refusing the services of regiment after regiment of mounted troops. General Meade deemed cavalry fit for little more than guard and picket duty, and wanted to know what would protect the transportation trains and artillery reserve, cover the front of moving infantry columns, and secure his flanks from intrusion, if my policy were pursued. I told him that if he would let me use the cavalry as I contemplated, he need have little solicitude in these respects, for, with a mass of ten thousand mounted men, it was my belief that I could make it so lively for the enemy's cavalry that, so far as attacks from it were concerned, the flanks and rear of the Army of the Potomac would require little or no defense, and claimed, further, that moving columns of infantry should take care of their own fronts. I also told him that it was my object to defeat the enemy's cavalry in a general combat, if possible, and by such a result establish a feeling of confidence in my own troops that would enable us after awhile to march where we pleased, for the purpose of breaking General Lee's communications and destroying the resources from which his army was supplied.
