Today is the 150th anniversary of the Battle of Antietam (or Sharpsburg, if you prefer) in 1862. It represents the bloodiest one-day battle in American history with over 23,000 casualties on both sides. Ethan Rafuse provides a wonderful post on this subject, complete with the opening to the film Glory (1989), which began with this battle.
This battle was significant for several reasons. One was that it allowed Lincoln to justify the Emancipation Proclamation, as the tactical draw served as a psychological and strategic victory for the Union, aiding in a small way in keeping the European powers out of the conflict, though this was largely accomplished by this point in 1862.
Also, it was a major setback for Robert E. Lee, as his invasion of the North failed. It represented a series of missed opportunities and blunders that could have ended the war sooner, had McClellan acted more decisively upon finding Lee’s Special Order 191, which was his battle plan, or had McClellan pursued and destroyed the Army of Northern Virginia after the battle.
Though, 150 years old, this battle is still an important event in our history, worthy of continuing staff rides by military educational programs around the country. One of the better books on the battle that is both scholarly and great for a general audience is James McPherson’s Crossroads of Freedom: Antietam, The Battle That Changed the Course of the Civil War (2002), as it discusses the larger significance of the battle as well as how it relates to the concept of freedom at the time. As we approach the anniversaries of some of the most important battles of the war, it will be notable to see how we reflect and what historians write and do to understand the importance of these events against our modern society.
