The battle of Gettysburg was fought July 1-3, 1863, with locations like Devil's Den, the Wheatfield and Little Round Top gaining notoriety for their part in the bloodiest conflict of the Civil War, where more than 51,000 soldiers were killed.
The iconic Gettysburg Address, a speech given by President Abraham Lincoln at the dedication of the Soldiers' National Cemetery, took place on Nov. 19, 1963.
"We can not dedicate — we can not consecrate — we can not hallow — this ground," Lincoln said. "The brave men, living and dead, who struggled here, have consecrated 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."
Here's a look — sometimes brutal, sometimes graphic — of that terrible battle, its aftermath and the historic speech that followed.

In July 1863, an unidentified Union soldier shown March 12, 1985, died in battle at Gettysburg clutching a photograph of his three children. All four went unidentified until November 1863, when a woman in Portsville, N.Y., saw the photos in a religious publication and identified them as her husband Sgt. Amos Humiston and their three children. In 1866, indirectly inspired by the incident, the Soldiers’ Orphans home was erected in Gettysburg, with Mrs. Humiston and her three children being part of its first 100 residents.

After convincing the Confederate Army that he was not a combatant, they treated his wounds and he was able to return home. President Abraham Lincoln later requested to meet Burns after his story spread across the country.
