Owing, however, to misunderstandings between Lee and Longstreet (q.v.), the Confederates did not attack early on the morning of the 2nd, so that Meade's army had plenty of time to make its dispositions. The Federal line at this time occupied the horse-shoe ridge, the right of which was formed by Culp's Hill, and the centre by the Cemetery hill, whence the left wing stretched southward, the III. corps on the left, however, being thrown forward considerably. The XII. held Culp's, the remnant of the I. and XI. the Cemetery hills. On the left was the II., and in its advanced position--the famous "Salient"--the III., soon to be supported by the V.; the VI., with the reserve artillery, formed the general reserve. It was late in the day when the Confederate attack was made, and valuable time had been lost, but Longstreet's troops advanced with great spirit. The III. corps Salient was the scene of desperate fighting; and the "Peach Orchard" and the "Devil's Den" became as famous as the "Bloody Angle" of Spottsylvania or the "Hornets' Nest" of Shiloh. While the Confederate attack was developing, the important positions of Round Top and Little Round Top were unoccupied by the defenders--an omission which was repaired only in the nick of time by the commanding engineer of the army, General G. K. Warren, who hastily called up troops of the V. corps. The attack of a Confederate division was, after a hard struggle, repulsed, and the Federals retained possession of the Round Tops. The III. corps in the meantime, furiously attacked by troops of Hill's and Longstreet's corps, was steadily pressed back, and the Confederates actually penetrated the main line of the defenders, though for want of support the brigades which achieved this were quickly driven out. Ewell, on the Confederate left, waited for the sound of Longstreet's guns, and thus no attack was made by him until late in the day. Here Culp's Hill was carried with ease by one of Ewell's divisions, most of the Federal XII. corps having been withdrawn to aid in the fight on the other wing; but Early's division was repulsed in its efforts to storm Cemetery Hill, and the two divisions of the centre (one of Hill's, one of Ewell's corps) remained inactive.
