Hint: The Battle of Antietam, also known as Sharpsburg, was a battle during the American Civil War, particularly in the South of the USA. The war was started by the Union 1 Corps under Joseph Hooker at dawn (approx. 5:30 a.m.) on September 17.
Complete answer: The Battle of Antietam was the first time Confederate general Robert E. Lee entered the Union during the Civil War. Antietam is a Maryland town. On September 14th, Union forces struck at South Mountain, just west of Frederick, taking the Confederates off balance. With over 23,000 deaths, September 17, 1862, was the bloodiest day in American history.
The American Civil War had begun its second year, and the Confederate States of America was on the brink of declaring victory and freedom. During that month, Confederate General Robert E. Lee and his Army of Northern Virginia conducted a brazen and daring attack into Maryland, putting several things in jeopardy. The invasion culminated in the Battle of Antietam, one of the most pivotal battles of the Civil War.
The Confederacy lost so many troops during the war that they didn't return for a long time. The fight was won by the Union. After the battle, commander-in-chief Abraham Lincoln shot Union general George McClellan. General McClellan was a dreadful commander. The Emancipation Proclamation was issued as a result of the Union success.
Note: i) The struggle commenced very early in the morning as the Union troops attacked the left side of the Confederate army. This part of the struggle raged around the cornfield of a farmer and is now known as merely 'The Cornfield.' ii) Antietam fought on an old farm road. Antietam was also fought. Confederates maintaining this road used it until they were forced out of place to avoid several waves of Union assailants. Today, this route is called "Bloody Lane."
