Civil War Battles
Battle of Antietam
The Northern General - George B. McClellan
The Battle of Antietam is the deadliest single day of the Civil War lasting 8 hours with 21,000 dead. General Lee planned a very well thought out plan, which failed before he had a chance to utilize it because an officer of his lost the paper stating the orders given, resulting in Union Soldiers finding it, and reporting it to Mclellan. President Lincoln uses this battle to make the Emancipation Proclamation, essentially changing the true purpose of the war.
Battle of Gettysburg
Northern General - George G. Meade
The Battle of Gettysburg was the deadliest battle of the whole Civil War. This particular battle was going on at the same time as the Battle of Vicksburg, but only lasted three or four days. As a result of this battle, President Lincoln ended up redefining the purpose of the nation. The political aspect of this battle was the Gettysburg address which is referred to as the most famous speech ever given by Lincoln.
Battle of Vicksburg
Southern General - Robert E. Lee
The Battle of Vicksburg lasted a month, overlapping with the Battle of Gettysburg, Both ending on July 4. The Union took control of the Mississippi, using the Anaconda plan (surrounding the South, essentially "choking" them). This Battle changed the tide of the Civil War.
