Abraham Lincoln: Abraham Lincoln was the 16th President of the United States and is considered one of the most influential figures in American history. He was elected in 1861, just as the Civil War was beginning, and led the Union through the conflict. Lincoln is credited with preserving the Union and issuing the Emancipation Proclamation, which freed enslaved people in the Confederate states.
Antietam: The Battle of Antietam was one of the bloodiest battles of the Civil War and marked a turning point in the conflict. Fought on September 17, 1862, near Sharpsburg, Maryland, the battle resulted in a tactical draw, but it gave the Union a strategic victory as it prevented Confederate General Robert E. Lee from invading the North. The battle also led to the issuance of the Emancipation Proclamation.
Army of the Potomac: The Army of the Potomac was the main Union army in the eastern theater of the Civil War. It was initially commanded by General George B. McClellan and was involved in several significant battles, including the Battle of Antietam and the Battle of Gettysburg. The Army of the Potomac was eventually led by General Ulysses S. Grant and played a pivotal role in the Union victory.
