Our march on the 13th, was an easy one of six miles. As we reached the brow of a hill overlooking the plain of Cumberland Landing, a scene of imposing beauty was spread out before us. Between us and the broad river, were thousands of troops, parks of artillery, squadrons of cavalry, divisions of infantry; some already in camp, others moving about in order, but seeming, from the distance, to be intermingled in most perfect confusion. A broad plain stretched far away to the left, beautifully variegated with green pastures, rich groves and fields of grain. Beyond was the Pamunkey; here spreading out into a broad expanse of water, on which was riding the Union flotilla of gunboats and the transport fleet. Upon this broad plain the whole army assembled. At no other time in the history of the Army of the Potomac, were all its forces gathered within a compass that the eye could take in at a single glance. Early on the morning of the 14th, the cry, "Fall in!" resounded through the camps, and we proceeded up the river about four miles, and again encamped on its banks. A field of fresh clover served for our bivouac. In this pleasant spot we remained for several days; and while here, an event occurred of no less interest than the organization of the Sixth corps. Just before the Army of the Potomac embarked for the Peninsula, it was divided, by order of President Lincoln, into five corps of three divisions each. These corps were placed under command, respectively, of Generals McDowell, Sumner, Heintzelman, Keyes and Banks. On leaving for the Peninsula, the First and Fifth corps had been left behind. Now two new corps were to be organized; the Fifth provisional, consisting of the divisions of Porter and Sykes, and the reserve artillery, under command of General Porter; and the Sixth provisional corps, consisting of Franklin's division of the First and Smith's of the Fourth corps. General W. B. Franklin was assigned to the command of the corps. Franklin's division, now the First division, Sixth corps, under command of H. W. Slocum, had been ordered away from the First corps, to join the army of the Potomac, while we were at Yorktown; and its recent exhibition of gallantry at West Point, had already established for it a reputation for valor. The regiments composing this division were, the First, Second, Third and Fourth New Jersey; regiments trained to the service by the knightly soldier and ardent patriot, Philip S. Kearney, now under command of Colonel Taylor, and afterwards so long and so ably led by General Torbert; the Sixteenth and Twenty-seventh New York, Fifth Maine and Ninety-Sixth Pennsylvania; General Slocum's own brigade, now commanded by Colonel Bartlett; and Newton's brigade: the Eighteenth, Thirty-first and Thirty-second New York, and Ninety-fifth Pennsylvania.
