Little Round Top, the key to the Federal left at Gettysburg, which they all but lost on the second day--was the scene of hand-to-hand fighting rarely equaled since long-range weapons were invented. Twice the Confederates in fierce conflict fought their way near to this summit, but were repulsed. Had they gained it, they could have planted artillery which would have enfiladed the left of Meade's line, and Gettysburg might have been turned into an overwhelming defeat. Beginning at the right, the Federal line stretched in the form of a fish-hook, with the barb resting on Culp's Hill, the center at the bend in the hook on Cemetery Hill, and the left (consisting of General Sickles' Third Corps) forming the shank to the southward as far as Round Top. On his own responsibility Sickles had advanced a portion of his line, leaving Little Round Top unprotected. Upon this advanced line of Sickles, at the Peach Orchard on the Emmitsburg road, the Confederates fell in an effort to turn what they supposed to be Meade's left flank. Only the promptness of General Warren, who discovered the gap and remedied it in time, saved the key. [Illustration: THE HEIGHT OF THE BATTLE-TIDE COPYRIGHT, 1911, REVIEW OF REVIEWS CO.] Near this gate to the local cemetery of Gettysburg there stood during the battle this sign: "All persons found using firearms in these grounds will be prosecuted with the utmost rigor of the law." Many a soldier must have smiled grimly at these words, for this gateway became the key of the Federal line, the very center of the cruelest use of firearms yet seen on this continent. On the first day Reynolds saw the value of Cemetery Hill in case of a retreat. Howard posted his reserves here, and Hancock greatly strengthened the position. One hundred and fifty Confederate guns were turned against it that last afternoon. In five minutes every man of the Federals had been forced to cover; for an hour and a half the shells fell fast, dealing death and laying waste the summer verdure in the little graveyard. Up to the very guns of the Federals on Cemetery Hill, Pickett led his devoted troops. At night of the 3d it was one vast slaughter-field. On this eminence, where thousands were buried, was dedicated the soldiers' National Cemetery. [Illustration: PICKETT--THE MARSHALL NEY OF GETTYSBURG]
