The section that received my closest attention has its northern limit along the Potomac between McCoy's ferry at the eastern base of the North Mountain, and Harper's Ferry at the western base of the Blue Ridge. The southern limit is south of Staunton, on the divide which separates the waters flowing into the Potomac from those that run to the James. The western boundary is the eastern slope of the Alleghany Mountains, the eastern, the Blue Ridge; these two distinct mountain ranges trending about southwest inclose a stretch of quite open, undulating country varying in width from the northern to the southern extremity, and dotted at frequent intervals with patches of heavy woods: At Martinsburg the valley is about sixty miles broad, and on an east and west line drawn through Winchester about forty-five, while at Strasburg it narrows down to about twenty-five. Just southeast of Strasburg, which is nearly midway between the eastern and western walls of the valley, rises an abrupt range of mountains called Massanutten, consisting of several ridges which extend southward between the North and South Forks of the Shenandoah River until, losing their identity, they merge into lower but broken ground between New Market and Harrisonburg. The Massanutten ranges, with their spurs and hills, divide the Shenandoah Valley into two valleys, the one next the Blue Ridge being called the Luray, while that next the North Mountain retains the name of Shenandoah.
A broad macadamized road, leading south from Williamsport, Maryland, to Lexington, Virginia, was built at an early day to connect the interior of the latter State with the Chesapeake and Ohio canal, and along this road are situated the principal towns and villages of the Shenandoah Valley, with lateral lines of communication extending to the mountain ranges on the east and west. The roads running toward the Blue Ridge are nearly all macadamized, and the principal ones lead to the railroad system of eastern Virginia through Snicker's, Ashby's Manassas, Chester, Thornton's Swift Run, Brown's and Rock-fish gaps, tending to an ultimate centre at Richmond. These gaps are low and easy, offering little obstruction to the march of an army coming from eastern Virginia, and thus the Union troops operating west of the Blue Ridge were always subjected to the perils of a flank attack; for the Confederates could readily be brought by rail to Gordonsville and Charlottesville, from which points they could move with such celerity through the Blue Ridge that, on more than one occasion, the Shenandoah Valley had been the theatre of Confederate success, due greatly to the advantage of possessing these interior lines.
Nature had been very kind to the valley, making it rich and productive to an exceptional degree, and though for three years contending armies had been marching up and down it, the fertile soil still yielded ample subsistence for Early's men, with a large surplus for the army of Lee. The ground had long been well cleared of timber, and the rolling surface presented so few obstacles to the movement of armies that they could march over the country in any direction almost as well as on the roads, the creeks and rivers being everywhere fordable, with little or no difficulty beyond that of leveling the approaches.
I had opposing me an army largely composed of troops that had operated in this region hitherto under "Stonewall" Jackson with marked success, inflicting defeat on the Union forces almost every time the two armies had come in contact. These men were now commanded by a veteran officer of the Confederacy-General Jubal A. Early--whose past services had so signalized his ability that General Lee specially selected him to take charge of the Valley District, and, notwithstanding the misfortunes that befell him later, clung to him till the end, of the war. The Confederate army at this date was about twenty thousand strong, and consisted of Early's own corps, with Generals Rodes, Ramseur, and Gordon commanding its divisions; the infantry of Breckenridge from southwestern Virginia; three battalions of artillery; and the cavalry brigades of Vaughn, Johnson, McCausland, and Imboden. This cavalry was a short time afterward organized into a division under the command of General Lomax.
After discovering that my troops were massing in front of Harper's Ferry, Early lost not a moment in concentrating his in the vicinity of Martinsburg, in positions from which he could continue to obstruct the Baltimore and Ohio railroad, and yet be enabled to retire up the valley under conditions of safety when I should begin an offensive campaign.
When I took command of the Army of the Shenandoah its infantry force comprised the Sixth Corps, one division of the Nineteenth Corps, and two divisions from West Virginia. The Sixth Corps was commanded by Major-General Horatio G. Wright; its three divisions by Brigadier-Generals David A. Russell, Geo. W. Getty, and James B. Ricketts.
