Confederate Army victory:
-Battle of Chancellorsville
Explanation:
-The Battle of Antietam was the first great armed confrontation of the Civil War that took place in northern territory. The battle took place on September 17, 1862, near Sharpsburg, in the county of Washington, Maryland, United States, in the vicinity of the Antietam stream. The battle was part of the Maryland Campaign and is the bloodiest in the history of the United States that was fought in a single day, with almost 23,000 casualties.
As a result of this battle, the invasion of Maryland by Lee was stopped, although this one could retire to Virginia without opposition on the part of the cautious Union forces. While the battle did not produce a conclusive result in tactical terms, it had a unique importance, since Lee's withdrawal was enough to give President Abraham Lincoln the confidence to announce the Emancipation Proclamation.
-The Battle of Chancellorsville was fought near Spotsylvania Courthouse, Virginia, between April 30 and May 6, 1863. The battle pitted the Army of the Potomac against the confederate Northern Virginia Army of General Robert E. Lee. It is known as Lee's "perfect battle" because of his risky but successful decision to split his army in the presence of a far superior enemy force.
The Chancellorsville Campaign began with the crossing of the Rappahannock River by the Union Army on the morning of April 17, 1863. After crossing the Rapidan River through the fords of Germanna and Ely, the federals concentrated near Chancellorsville between April 30 and May 1. On May 1, intense fighting began that did not end until Union forces retreated across the river on the night of May 5 to 6.
-The Battle of Gettysburg was a battle of the Civil War, fought between July 1 and 3, 1863 around the town of Gettysburg, Pennsylvania, as part of the Gettysburg campaign. It was the battle with more casualties in the United States, which is considered the turning point of the Civil War along with the Siege of Vicksburg; and that, in addition, marked the beginning of the Union's offensive. It was a great victory for the Union Army and a disastrous event for the Confederation.
