      Cemetery Hill.

      From a military point of view there are but two features about Gettysburg on which the eye would long rest. These are the two ridges, with a broad valley between, heaved up at east and west and running off south of the town. They stand about a mile apart, though the distance is sometimes less than that. As it nears Gettysburg the easternmost ridge glides down, by a gentle slope, into what may be called a plain, in comparison with the upheavals around it, although it is by no means a dead level. Yet it is open because the ridges themselves have stopped short here, forming headlands, so to speak, above the lower swells. On coming down off this ridge the descent is seen to be quite easy—in fact, two roads ascend it by so gradual a rise that the notion of its being either high or steep is quite lost, and you are ready to discard off-hand any preconceived notion about its being a natural stronghold. It is mostly on this slope that Gettysburg is built, its houses extending well up toward the brow, and its cemetery occupying the brow itself. Hence, although the centre of Gettysburg may be three-fourths of a mile from the cemetery gate, the town site is in fact but a lower swell of the historic ridge which has since taken the name of its graveyard—Cemetery Ridge.

      Seminary Ridge.

Across this valley, again, the western ridge, which looks highest from the town, has what Cemetery Hill has not, namely, a thin fringe of trees skirting its entire crest, thus effectually masking the view in that direction; and it is further distinguished by the cupola of the Lutheran Seminary,[4] seen rising above trees at a point opposite the town, and giving its name to this ridge—Seminary Ridge. Both ranges of heights are quite level at the top, and easily traversed; so also the slopes of both are everywhere easy of ascent, the ground between undulating, but nowhere, except far down the valley, badly cut up by ravines or watercourses. Indeed, better ground for a fair stand-up fight it would be hard to find; for all between the two ridges is so clear and open that neither army could stir out toward its opponent without being detected at once—the extreme southern part of the valley excepted. In this respect I take the liberty of observing that the actual state of things proved very different from that conveyed in some of the published accounts, wherein Cemetery Ridge is represented as a sort of Gibraltar.

      A very brief survey, however, suggests that an army could be perfectly hid behind the trees of Seminary Ridge, as well as better sheltered from artillery fire, while one stretched out along the bare and treeless summit of Cemetery Ridge would be without such screen or protection.

      The description must be a little farther pursued, if the battle is to be at all intelligently followed.

      Enough for the two main ridges enclosing Gettysburg and its valley. We come now to that most striking feature of the landscape, notably on the side of Cemetery Ridge, but more or less characteristic of both sides of the valley. This is the group of hills standing off from Cemetery Ridge at either end, just as if, at some remote time, this ridge had formed a continuous chain, the summits of which had been cleanly shaved off at the centre, leaving these isolated clusters to show where the wasting forces had passed. From different points of view we may see one or both of them rising above the ridge like giant watch-towers set at the extremities of some high embattled wall.

      Culp's Hill.

      Rock Creek.

Let us first take the northernmost cluster, formed of Wolf's, McAllister's, and Culp's hills. It is seen to be thrown back behind Cemetery Hill, to which Culp's Hill alone is slenderly attached by a low ridge, so making an elbow with it, or, in the military phrase, a refused line. Between Culp's Hill and Wolf's Hill flows Rock Creek, the shallow stream so often mentioned in connection with the battle, its course lying through a shaggy ravine.[5] The ravine and stream of Rock Creek threw Wolf's Hill somewhat out of the true line of defence, but the merest novice in military art sees at a glance why the possession of Culp's Hill was all-essential to the security of Cemetery Hill, since there is little use in shutting the front door if the back door is to be left standing open.

      The Round Tops.

      The Devil's Den.

The same is just as true of the southernmost group, composed of Little and Great Round Tops, two exceedingly picturesque summits, standing up above the generally monotonous contours about them in strong relief. They also were wooded from base to summit, and they show, even more distinctly than the first group, where the crushing out or denuding forces have been at work, in shelves or crevices of broken ledge at the highest points, in ugly bowlders cropping out on the slopes, in miry gullies crawling at their feet, but most of all in the deformed heap of ripped-up ledges, topped with coppices and scattered trees, thrust out from Little Round Top and known as the Devil's Den.[6]

      When it is added that the way is open between the two Round Tops to the rear of Cemetery Ridge, the importance of holding them firmly becomes self-evident; and inasmuch as the greatest natural strength of this ridge lay at its extremities, or flanks, so its weakness would result from a neglect to occupy those flanks.

      The Swale.

      This line was assailable at one other point. As it approaches Little Round Top the ridge sinks away to the general level around it, or so as to break its continuity, thus leaving a gap more or less inviting the approach of an enemy. The whole extent of this crooked line, at which we have just glanced, is about two and a half miles.

      Emmettsburg Road.

      Down below, in the valley, there is another swell of ground, hardly worth dignifying by the name of ridge, yet assuming a certain importance, nevertheless, first because it starts from the town close under Cemetery Hill, thence crossing the valley diagonally till it becomes merged in Seminary Ridge, at a point nearly opposite to the Round Tops, and next because the Emmettsburg road runs on it. In brief, its relation to the battle was this: it ran from the Union right into the Confederate right, so traversing the entire front of both armies. It had an important part to play in the second day's battle, as we shall soon see, for, though occupying three days, Gettysburg was but a series of combats in which neither army employed its whole force at any one time.
