Explanation:By evening, the Federal troops rallied on high ground on the southeastern edge of Gettysburg. As more troops arrived, Meade’s army formed a three-mile long, fishhook-shaped line running from Culp’s Hill on the right flank, along Cemetery Hill and Cemetery Ridge, to the base of Little Round Top. The Confederates held Gettysburg, and stretched along a six-mile arc around the Union position. Lee’s forces would continue to batter each end of the Union position, before launching the infamous Pickett’s Charge against the Union center on July 3.
