Lee, too, was out of harmony with Longstreet, his well-tried second; and the first matter in dispute was the expediency of fighting at all at Gettysburg. When Longstreet, coming from Chambersburg, took in the situation, he urged upon Lee, bent upon his battle, a turning of the Federal left as better strategy, by which the Confederates might interpose between Meade and Washington and compel Meade to make the attack. Longstreet held Lee to be perfect in defensive warfare; on the offensive, however, he thought him “over-combative” and liable to rashness.[258] Lee rejected the advice with a touch of irritation; and when Longstreet, acquiescing, made a second suggestion--namely, for a tactical turning of the Federal left instead of a direct assault--Lee pronounced for the assault in a manner so peremptory that Longstreet could say no more. From first to last at Gettysburg, Longstreet was ill at ease, in spite of which his blows fell like those from the hammer of a war-god. The friends of Lee have denounced him for a sluggishness and insubordination that, as they claim, lost for them the battle.[259] His defence of himself is earnest and pathetic, of great weight as coming from one of the most able and manful figures on either side in the Civil War. Of Longstreet’s three divisions, only one, that of McLaws, was on hand with all its brigades on the forenoon of July 2d. At noon arrived Law, completing Hood’s division. Pickett’s division was still behind; but in mid-afternoon, without waiting for him, Longstreet attacked--Hood, with all possible energy, striking Sickles in his far-advanced position and working dangerously around his flank toward the Round Tops. Longstreet’s generals, Hood and afterward Law (Hood falling wounded in the first attack), though men of courage and dash, assaulted only after having filed written protests, feeling sure that the position could be easily turned and gained with little fighting. But Lee had been peremptory, and no choice was left.[260] [Illustration: POSITION, JULY 2, 2.30 P.M.] Gouverneur K. Warren, then chief-engineer of the Army of the Potomac, despatched by Meade to the left during the afternoon, found the Round Tops undefended. They were plainly the key to the Federal position, offering points which, if seized by the enemy, would make possible an enfilading of the Federal line. Troops of the Twelfth Corps, at first stationed there, had been withdrawn and their places not supplied. There was not a moment to lose. Even as he stood, Warren beheld in the opposite woods the gleam of arms from Longstreet’s swift advance. Leaping down from ledge to ledge, he met a brigade of the Fifth Corps, just arrived and marching to the aid of Sickles. These he diverted to the eyrie he had so lately left; a battery, too, was dragged up over the rocks, and none too soon. At that very moment the men of Hood charged out of the valley, and the height was held only by the most obstinate combat.
