LONGSTREET ATTACKS ON THE RIGHT.
In the execution of this plan, Longstreet was ordered to take position across the Emmitsburg Road and to attack what was thought to be the left flank of the Union line on Cemetery Ridge. From his encampment on the Chambersburg Road, 3 miles west of Gettysburg, he started toward his objective, using Herr Ridge to conceal the movement from Union signalmen on Little Round Top. After marching to Black Horse Tavern on the Fairfield Road, he realized that his troops were in sight of the signal unit and at once began retracing his course. Employing the trees on Seminary Ridge as a screen, he marched southward again in Willoughby Run Valley, arriving in position on the Emmitsburg Road about 3:30 p. m. Immediately in front, and only 700 yards away, Longstreet saw Sickles’ batteries lined up in the Peach Orchard and on the Emmitsburg Road. Col. E. P. Alexander, commanding a battalion of Longstreet’s artillery, opened with full force against the Union guns. Longstreet could observe in the distance that Little Round Top was unoccupied. Law’s Alabama troops were directed at once to take the hill, and Robertson’s Texans were instructed to join in the charge.
