BOOK IV.-THIRD WINTER.

CHAPTER I.

HAGERSTOWN.

N the evening of July 4th the two armies present near Gettysburg have already had time to review their situation and to estimate the extent of their losses. Including prisoners, the Confederate infantry has been reduced by more than one-third, the Federal infantry by over one-fourth. On both sides the officers exposed themselves gallantly, and the most adventurous chiefs were struck. Moreover, the Army of the Potomac, in addition to its positive losses, is still further reduced by the absence of from twelve to fifteen thousand men who did not answer to their names at the morning roll-call on the 4th.

The retreat of the Confederate army is begun; Lee's plan is decided on. His objective is the ponton bridge left by him on the Potomac at Falling Waters, four miles below the ford at Williamsport. To recruit his strength before risking further battles, his army must again set foot on the friendly soil of Virginia. Still, as we have said, Meade cannot as yet realize the full extent of his own success. He hesitates, and wishes to wait twenty-four hours before deciding what course to pursue. This first fault will be followed by many another which will entail upon the Army of the Potomac the loss of part of the advantages which its victory ought to have secured.

Indeed, the recollection of the check experienced by the Confederates in their ineffectual assaults upon the Unionist positions will haunt the mind of Meade so long as he will find himself alone confronting Lee. He will think of nothing but obliging Lee to renew those assaults; he will constantly avoid assuming the offensive when he finds Lee posted in his front; and, as the Southern general is above all anxious to be sparing of his troops,

battles will be followed by evolutions. The Army of the Potomac, which since its arrival at Fort Monroe has fought eleven pitched battles in sixteen months, is now going to remain ten months without renewing those great contests. But that will not be for want of marching or for not feeling its adversary's pulse. A result so important for the Confederate cause is almost sufficient to justify the campaign, highly imprudent in other respects, which was unexpectedly interrupted at Gettysburg.

As we said, Lee, with about forty thousand men on Seminary Hill, was covering the two roads of Fairfield and Cashtown. One large train has taken the latter. Another, composed principally of the wagons of the Second corps, follows the first, which is shorter, and on which it precedes the army. Stuart will reconnoitre on its flank toward Emmettsburg, and Robertson and Jones will protect it in the defiles of South Mountain. As soon as the sun is down Hill's corps begins its march. That of Longstreet, which follows, is guarding the four thousand Federal prisoners; Pickett's division will conduct them as far as Williamsport, without allowing itself to be turned aside by the strategic movements which may be prescribed to the remainder of the First corps. The Second, by its position, the most remote from the Fairfield road, closes the line of march. Each corps is followed by quite a considerable number of wagons and by its artillery, and Early's division, having charge of the rear-guard, which left its bivouac at two in the morning, sees the sun rising above the heights of Gettysburg without being able to advance on the encumbered road: the Confederate army seems to regret leaving these heights, at the base of which so many valiant soldiers lie. Early's position is perilous, for, Stuart having started with three brigades for Emmettsburg, a mere curtain of cavalry covers the retreat of the former, and the Federal signal corps on Round Top have for some time past been signalling his movements. Fortunately for him, Meade, as yet, has given no order.

Before proceeding any further we must indicate rapidly the configuration of the country which the two armies are about to cross in order to reach the banks of the Potomac. We have already said that South Mountain, a prolongation of the Blue Ridge, separates the fertile Cumberland Valley

from the undulating plain which lies between the Potomac on the south, the Susquehanna on the north, and Chesapeake Bay on the east. It was by the Cumberland Valley that Lee penetrated Pennsylvania: he had gone out of it to march on Gettysburg; he returned to it to resume the road to Virginia. Besides the railroad which from Harrisburg and Carlisle is extended through Chambersburg and Greencastle as far as Hagerstown, the Cumberland Valley is furrowed by several great roads and numerous ways, all practicable in summer-time. A flourishing agriculture spares the ancient forests only on the mountainsides and in soil naturally poor. Everywhere else the cultivation of the cereals alternates with pasturage which feeds numerous herds of cattle. The country is consequently open, although it is unfavorable to military evolutions, as it opposes to manœuvres in line the obstacle of frequent fences either of wood or stone.

During the previous year, before the battle of Antietam, Lee had defended the crest of South Mountain. But this crest is very long, its passages are very numerous, and paths which scale the summit allow of the principal gaps being turned. For this reason the Southern general did not think it would be possible for him the day after a defeat to pause on that line. Full of confidence, doubtless, in the slowness of his adversaries, he did not even think of availing himself of such an obstacle if they should venture to cross the river in his rear. By reason of the course of the Potomac between Hancock and Harper's Ferry, he hoped to be able to cross over into Virginia before Meade came up with him. At Hancock, the most northerly point of the river, it almost reaches the boundary-line of Pennsylvania; at Williamsport it receives, by the Conococheague, the greater part of the waters of the Cumberland Valley; then, as it nears Harper's Ferry before passing the mountains, it winds between the smaller heights which run parallel to the principal chain and furrow the plain. From Hancock to Williamsport its course is east-south-east; from that point to Harper's Ferry it gradually inclines to the south. The country situated on the left bank of the river in this latter part of its course is much more undulating and less fertile than the remainder of the Cumberland Valley. It is intersected by an important stream, the Antietam, and by rivulets that are very

marshy and which are swollen by the first rainfall, enclosed by hills the sides of which are generally wooded.

Lee directed his course toward Williamsport, because it is the point on the Potomac the least remote from Gettysburg. The angle formed by the river at this place offered another advantage for the crossing of the Confederate army. If Meade followed that army step by step, the two branches of the angle protected both its flanks as soon as the passage should be effected, and the army could then descend by the right bank as far as Harper's Ferry fully covered by the river; for the fear of exposing Washington prevented Meade from penetrating Virginia by Williamsport. For the same reason he could not cross the Potomac in advance of his adversary, and if he sought the passage of South Mountain in order to return from there on Williamsport, he would make a détour which would give Lee abundant time to pass into Virginia. The pontons on which Longstreet and Hill had crossed the river were at Falling Waters, inside of a bend near which runs the turnpike road from Martinsburg to Williamsport. To reach this last point Lee could avail himself of a high road which was all the better because it had not as yet been travelled by either of the two armies. This road, which begins at Gettysburg, crosses Marsh Run at Black Horse Tavern, and reaches, after running seven miles, the village of Fairfield, at the foot of one of the bases of South Mountain called Jack's Mountain: following this base, it strikes, three miles farther on, at Fountain Dale, the village of Monterey Springs. From there, passing several secondary ranges, it descends to the town of Waynesboro' at the entrance into the Cumberland Valley. The distance from Gettysburg to Waynesboro' is twenty miles; from there to Hagerstown, through Leitersburg, the road runs eleven more, and finally six miles before reaching Williamsport. Only two other principal roads cross South Mountain-the one from Chambersburg to Gettysburg to the north, followed by Lee's army in its offensive march, and that to the south, the road from Washington to Hagerstown through Turner's Gap, which was carried by McClellan in 1862. But between the Potomac and the Monterey Gap several roads, some of them even passable for artillery, debouch into the Cumberland Valley: all, with

mac.

one exception, have a double obstacle to pass, for on the south of Jack's Mountain South Mountain forks, one branch, parallel to the principal chain, following it on the east under the name of Catoctin Mountain. In the valley of Catoctin Creek, which separates them, are found the villages of Myersville, Middletown, Jefferson, Burkittsville, and finally Knoxville and Berlin on the PotoFrederick is at the foot of the eastern slope of the secondary chain. The only passage situated to the north of this fork branches off into the high road between Fairfield and Monterey, and descends on Ringgold by the passage of Riker's Gap. The first passage to the south goes from Mechanicstown to Hagerstown, crossing the principal chain at Harmon's Gap, above the village of Cavetown; the second connects Lewistown with Berlin, where it crosses the Catoctin, and at the debouch of Braddock's Gap in South Mountain forks-on the right to Funkstown and to Hagerstown, on the left to Boonsboro', a large village at the foot of the mountain. Quite close to Turner's Gap, Fox's Gap opens a passage to the direct road from Middletown to Sharpsburg by Springvale. Farther to the south the road from Burkittsville to Rohrersville crosses the well-known pass of Crampton's Gap; finally, the towpath of the canal lateral to the Potomac, with the railroad at Knoxville, goes round the extremity of South Mountain. There was, therefore, no scarcity of roads for Meade to penetrate the Cumberland Valley: the most of them terminate at Hagerstown, the central nucleus in this region, as Gettysburg is farther north on the opposite slope.

The wagon-train sent by Lee on the Fairfield road had reached that village on the afternoon of July 4th, and, escorted by Jones' and Robertson's cavalry brigades, it had continued its march toward Monterey. As we said, the Federal army had remained immovable that day, with the exception of Kilpatrick's division, which had been sent at daybreak on the 4th on the Emmettsburg road. Pleasonton and his division commanders knew that boldness and promptness are qualities indispensable in cavalry, and when once the order was given to follow the enemy, they construed it in the broadest sense. So, while Buford was hurrying his horsemen on the road to Frederick, Kilpatrick, after having on his way
