Ewell began fighting on Culp's Hill at first light. Lee rode to Longstreet's headquarters only to find Longstreet had misunderstood his orders. He was planning a turning movement against the Union left. Now, with no hope of a coordinated attack, Lee changed the plan. Longstreet was to attack the Union center on Cemetery Ridge. Ewell's forces failed in their counterattacks and were forced to withdraw from Culp's Hill by about 11:00 a.m. Lee pinned all his hopes on Longstreet's attack on the center. Longstreet had the last fresh division in Lee's army. It was made up of three brigades, commanded by generals James L. Kemper, Richard B. Garnett, and Lewis A. Armistead, led by Pickett.
