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.

THE MARCH INTO PENNSYLVANIA
Lee in Maryland.
It is in no way essential to relate in detail how Lee's army, slipping away from ours on the Rappahannock,7 and after brushing out of its path our troops posted in the Shenandoah Valley, had been crossing the Potomac into Maryland since the 21st of June, by way of the Cumberland Valley, without firing a shot.8
His Bold Strategy.
A very unusual thing in war it is to see an army which has just been acting strictly on the defensive suddenly elude its adversary for the purpose of carrying the war into that enemy's country! It marks a new epoch in the history of that war, and it supposes wholly altered conditions. In this particular instance Lee's moves were so bold as almost to savor of contempt.
It is enough to know that Lee was now in Pennsylvania, at the head of seventy thousand men, before our army reached the Potomac in pursuit of him, if following at a respectful distance be called a pursuit.
State of his Army.
At no period of the war, their own officers said, had the Confederates been so well equipped, so well clothed, so eager for a fight, or so confident of success; and we may add our own conclusions, that never before had this army taken the field so strong in numbers, or with such a powerful artillery.9
Superiority as Marksmen.
The infantry were armed with Enfield rifles, fresh from British workshops, and it is probable that no equal number of men ever knew how to use them better. Indeed, we consider it indisputable that the Confederates greatly excelled the Union soldiers as marksmen. Most of them were accustomed to the use of firearms from boyhood; in some sections they were noted for their skill with the rifle. The Confederates, therefore, were nearly always good shots before they went into the army, while the Union soldiers mostly had to acquire what skill they could after going into the ranks. In the South the habit of carrying arms was almost universal: in the North it was not only unusual, but unpopular as well as unlawful.
Superiority in Cavalry.
Man for man, the Confederate cavalry was also superior to the Union horse, because in one section riding is a custom, in the other a pastime rarely indulged in. Consequently, it took months to teach a Union cavalryman how to ride, – a costly experiment when your adversary is already prepared, – whereas if there is anything a Southerner piques himself upon, it is his horsemanship.10
Cavalry Advance.
Cumberland Valley raided.
Lee's cavalry had preceded the infantry by nearly a week, reaching Chambersburg on the 16th, seizing horses and provisions for the use of the army behind them, and spreading consternation to the gates of Harrisburg itself. Having loaded themselves with plunder unopposed, they then fell back upon the main army, thus leaving it in some doubt whether this raid accomplished all it designed, or was only the prelude to something for which it was serving as a mask.11
Ewell at Chambersburg.
Hood's Soldiers.
All doubts were set at rest, however, when, on the 23d, Ewell's dust-begrimed infantry came tramping into Chambersburg, regiment after regiment, hour after hour, until the streets fairly swarmed with them. Though the houses were shut up, a few citizens were in the streets, or looking out of their windows at the passing show, as men might at the gathering of a storm-cloud about to burst with destructive fury upon them; and though the time was hardly one for merriment, we are assured that some of these lookers-on could not refrain from "pointing and laughing at Hood's ragged Jacks" as they marched along to the tune of "Dixie's Land." "This division," remarks the partial narrator, "well known for its fighting qualities, is composed of Texans,
In 1863 all these hills were much more densely wooded than now, so forming an impenetrable screen to their defenders.
The bowlder-strewn strip of ground lying between Devil's Den and Little Round Top is the most impressive part of the field, I think.
He withdrew two corps, by his left, to Culpepper, leaving one in the trenches of Fredericksburg. Had this corps been crushed while thus isolated, as it ought, Lee's invasion must have ended then and there.
A glance at the map shows how the northerly bend of the Potomac facilitated an invasion by this route. The outposts at Harper's Ferry and Winchester having been forced, there was nothing to stop the enemy's advance.
The Confederate army comprised three infantry corps, and one of cavalry. Each corps had three divisions, each division averaged a little over four brigades, of which there were thirty-seven present at Gettysburg. The British Colonel Freemantle, who accompanied Lee's army, puts the strength of these brigades at two thousand eight hundred men each. The relative strength of the army corps was more nearly equal than in those of the Union army. The Confederates brought with them two hundred and seventy pieces of artillery.
The main body, under Stuart, had gone around the rear of the Union army, by Lee's permission, in the expectation of harassing it while on the march, and of then rejoining Ewell, on the Susquehanna. It failed to do either, and many attribute all of Lee's misfortunes in this campaign to the absence of Stuart.
Jenkins, who commanded, was paid in his own coin at Chambersburg, by the proffer of Confederate scrip in payment for some alleged stolen horses. He himself had been professedly paying for certain seized property in this same worthless scrip.
