November 19, 1863 — The battle of Gettysburg in Pennsylvania had raged on that field just four and a half months prior. Abraham Lincoln, president of the United States, stood on the same ground where General Robert. E. Lee had fought General George G. Meade with their respective Confederate and Union armies. On this single battle, there were over 23,000 casualties on the Union side and 23-28,000 on the Confederate side. Some would describe it as the turning point of the war in the Union’s favor; everyone would realize it to be the bloodiest battle in American history to date. 3,155 Union Soldiers were killed, and though the Confederate Soldiers’ deaths are not so well recorded, it is likely that more Americans died in these three days than in both recent Iraq and Afghan wars combined.

All of these casualties were Americans, and this is why the Civil War was so devastating. Over 750,000 men were killed (higher than long-standing previous estimates), which meant that during this war, there were an average of 420 combat deaths a day. This means that the Civil War cost more American military lives than World Wars I and II, the Vietnam War, the Korean War, the American Revolution, the War of 1812, the Mexican-American War and GWOT all combined.

The main reason for this is that Americans were fighting Americans. There has been recent debate as to the “veteran” status of Confederate soldiers, but they were no doubt all American citizens–that was the whole point of the Union not allowing them to divide and create their own nation. But this aspect immediate doubles the American casualties in every battle, as neighbor is fighting neighbor. The country was undoubtedly in more peril than ever before or since.

Lincoln stood on that same field months later, weary from leading the United States in its most trying time, literally fighting a mild case of smallpox, and facing a battered and tired military. His speech solidified equality as an inherent American value, and honored those that died at Gettysburg. Since then, the speech has been etched into American culture and is central to our nation’s history.
