The Battle of Gettysburg was a critical turning point in the American Civil War. During the first three days of July 1863, over 172,000 men and 634 cannons were positioned in an area encompassing 25 square miles. An estimated 569 tons of ammunition were expended and, when the battle had ended, the losses topped 51,000 in dead and wounded soldiers on both sides. While the Confederate army retreated after Gettysburg, the war would drag on another two years. It would be the most costly battle ever fought on U.S. soil. The battle was commemorated by Abraham Lincoln’s legendary address. Lincoln stated: “Now we are engaged in a great civil war, testing whether that nation or any nation so conceived and so dedicated can long endure. We are met on a great battlefield of that war. We have come to dedicate a portion of it as a final resting place for those who died here that the nation might live. This we may, in all propriety do. But in a larger sense, we cannot dedicate, we cannot consecrate, we cannot hallow this ground. The brave men, living and dead who struggled here have hallowed it far above our poor power to add or detract. The world will little note nor long remember what we say here, but it can never forget what they did here.” The world has remembered both the battle and Lincoln’s eloquent words.
General Robert E. Lee’s first invasion of the North culminated in the Battle of Antietam, the bloodiest single-day battle in American history. More soldiers were killed or wounded at Antietam than all the American dead in the Revolutionary War, the War of 1812, the Mexican War and the Spanish-American War combined. On September 17, 1862, General Robert E. Lee and 30,000 Confederate troops faced Major General George McClellan and 60,000 Union troops. It should have been a clear victory for McClellan, especially since his army had captured Lee’s Special Order No. 191 which directed Stonewall Jackson to march on Harpers Ferry. McClellan failed to use this information wisely, choosing instead to remain cautious. Jackson took Harpers Ferry and moved his 45,000 troops on to Antietam to reinforce Lee’s troops. McClellan was recalled to Washington and was relieved of his command.
