Chancellorsville, where he was wrong-footed by the unbeatable Lee-Jackson partnership - though at the cost of Jackson's life.
General Ambrose Burnside went to attack the Confederate Capitol in Richmound, Virginia. His attempt ended with and overwhelming defeat which was the significance. This failure lead to Burnside's replacement with General Joseph Hooker.
Even though Union General Joseph Hooker had an enormous two to one advantage of General Lee's army, not every Union general held a favorable view of Hooker's ability to lead the Army of the Potomac. In a letter to President Lincoln, General Sherman expressed these words: " I know Hooker well and tremble to think of his handling of 100,000 men in the presence of Lee. I fear the result of an advance by Hooker on Lee". Sherman proved to be correct and Lee's greatest victory at the Battle of Chancellorsville was close at hand.
The Confederate victory at the 1863 Battle of Chancellorsville resulted in the raid into the Union by General Lee. It also resulted in the replacement of Union General Joseph Hooker by President Lincoln in favor of General George Meade to lead the Army of the Potomac and pursue Lee into Pennsylvania.
As head of the Army of the Potomac, General Hooker had a substantial troop advantage at the Battle of Chancellorsville. Yet, he lost this battle to Robert E. Lee. US President Lincoln then appointed General Meade to replace Hooker. Chancellorsville was perhaps the best victory of Robert E. Lee and his Army of Northern Virginia.

President Lincoln understood that lack of civilian support could hamper the war effort. He also understood that Northern military victories could gain him more support and in addition help to bring the Union to victory. Although General Burnside was aggressive, he was also noted for his major failure at the Battle of Fredericksburg. It was also no secret that he had been a good friend to Democrat General George B. McClellan. In addition, the Army of the Potomac was the Union's premier fighting force and the battles in close by Virginia were high profile ones. With all that said, Lincoln's replacement for Burnside, General Joseph Hooker might have been considered a surprise. Hooker had done well at the Battle of Antietam, this did not go unnoticed. However, what many historians believe was strange about Hooker's promotion to lead the Army of the Potomac was his outspoken talk about how a military dictator might do better in winning the war. These were not rumors. Letters exchanged between Lincoln and Hooker covered this topic and Lincoln still appointed him to lead the Army of the Potomac.
