Although Chancellorsville was Lee's most brilliant victory, his army would never be the same again. Why?

General Jackson would be sorely missed at the battle of Gettysburg. The general who took his place was given responsibility for taking the hill at the fish hook of Cementary ridge. He did not attack the ridge. General Jackson would have attacked and possibly taken the high point before it was well defended by the Union.

If Lee's army had taken control of the ridge Gettysburg would have most likely have been a southern victory.

After General Jackson's death, Lee had to maintain control of the entire force, which made the Army of Northern Virginia less adaptable and responsive in battle. However, General Jackson could be trusted to take part of the army and command his part independently, leaving General Lee free to concentrate his attention on the larger part of the army more effectively.

Lee's army would never be the same again after the Battle of Chancellorsville because of the loss of General Stonewall Jackson. Jackson, one of Lee's most trusted and capable commanders, was accidentally shot by his own men during the battle and died from complications of pneumonia shortly thereafter. Jackson's death was a significant blow to the Confederate Army, depriving Lee of a key strategist and battlefield tactician. Without Jackson's leadership and military genius, Lee's army faced greater challenges in subsequent battles, including the pivotal Gettysburg campaign. Additionally, Jackson's death had a demoralizing effect on Confederate troops, who revered him as a legendary figure. Overall, the loss of Stonewall Jackson at Chancellorsville marked a turning point for Lee's army, signaling the beginning of a decline in its effectiveness and morale.
