Which to battles were important confederate victories?

Two significant Confederate victories during the American Civil War were the First Battle of Bull Run (July 1861) and the Battle of Chancellorsville (April-May 1863). The First Battle of Bull Run marked the Confederacy's first major victory, boosting Southern morale and demonstrating that the war would be longer than anticipated. The Battle of Chancellorsville, often considered General Robert E. Lee's greatest triumph, showcased strategic brilliance but also resulted in the loss of General Stonewall Jackson, which would impact future Confederate operations.
