The Union army, led by General George Meade, decisively defeated Lee's forces in a three-day battle that witnessed intense fighting and heavy casualties. Gettysburg marked a major setback for the Confederacy and boosted the Union's morale.
2. Battle of Vicksburg (May 18-July 4, 1863):
The Battle of Vicksburg was a crucial campaign in the Western Theater. Union forces under General Ulysses S.

General McClellan's forces managed to halt the Confederate's Maryland Campaign, leading to President Lincoln issuing the Emancipation Proclamation. The proclamation shifted the war's focus to include the abolition of slavery, motivating more men to join the Union cause and eroding foreign support for the Confederacy.
