Beginning on the right, Longstreet’s Corps held the ground west of Plum Run, including the base of Big Round Top, Devil’s Den, and the Peach Orchard. Pickett’s Division, after its arrival on the field on the morning of the 3rd, took the place of Anderson in reserve. Heth’s and Pender’s Divisions extended the line to the left on Seminary Ridge, connecting with part of Rodes’ Division in the western part of the town. Early’s and Johnson’s Divisions, after the engagement on the morning of the 3rd, held their positions of the 2nd. Changes in the positions of the batteries of artillery were made on the morning of the 3rd. A total of 138 guns were in position to operate. Those on the right were in charge of Colonel E. P. Alexander; those on the left under Colonel R. L. Walker. The Bliss Buildings. After the end of the engagement at Culp’s Hill at 10.30 A.M. there was a short battle for the capture of the Bliss house and barn, midway between the lines in front of Ziegler’s Grove. These buildings were occupied by Confederate sharpshooters, who were causing considerable loss in Hays’ line of the 2nd Corps at the grove. Two regiments were sent forward, the 12th New Jersey and the 14th Connecticut, and the buildings were captured and burned. The Artillery Duel. Until 1 o’clock there was comparative quiet. It was ended on the stroke of the hour by two guns of Miller’s battery belonging to the Washington artillery of New Orleans, posted near the Peach Orchard, and fired in rapid succession as a signal to the Confederate artillery. The Confederate Colonel Alexander says: “_At exactly 1 o’clock by my watch the two signal guns were heard in quick succession. In another minute every gun was at work. The enemy was not slow in coming back at us, and the grand roar of nearly the whole of both armies burst in on the silence._ “_The enemy’s position seemed to have broken out with guns everywhere, and from Round Top to Cemetery Hill was blazing like a volcano._” The artillery duel was but a preface, intended to clear the ground for the infantry action to follow. The order had already been given by Longstreet to Alexander: “_Colonel: The intention is to advance the infantry if the artillery has the desired effect of driving the enemy off, or having other effect such as to warrant us in making the attack. When the moment arrives advise General Pickett, and of course advance such artillery as you can use in making the attack._” General Wright, who was present when this order was received, expressed doubt as to whether the attack could be successfully made. He said: “_It is not so hard to go there as it looks; I was nearly there with my brigade yesterday. The trouble is to stay there. The whole Yankee army is there in a bunch._”
