Why did general longstreet want to leave Gettysburg?

General James Longstreet wanted to leave Gettysburg because he believed that the Confederate Army should not engage in a battle that was disadvantageous due to the Union's strong defensive position and the terrain. He advocated for a more strategic maneuvering approach, suggesting that the Confederacy should move around the Union forces to strike them at a more favorable location. Longstreet's concerns about the battle's potential for high casualties and his preference for a defensive strategy were central to his desire to withdraw from the fight at Gettysburg.
