American Civil War: Sergeant William Harvey Carney is awarded the Medal of Honor for his heroism in the Assault on the Battery Wagner in 1863.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction.

William Harvey Carney was an American soldier during the American Civil War. Born enslaved, he was awarded the Medal of Honor in 1900 for his gallantry in saving the regimental colors during the Battle of Fort Wagner in 1863. The action for which he received the Medal of Honor preceded that of any other African American Medal of Honor recipient; however, his medal was actually one of the last to be awarded for Civil War service. Some African Americans received the Medal of Honor as early as April 1865.

The Medal of Honor (MOH) is the United States Armed Forces' highest military decoration and is awarded to recognize American soldiers, sailors, marines, airmen, guardians, and coast guardsmen who have distinguished themselves by acts of valor. The medal is normally awarded by the president of the United States and is presented "in the name of the United States Congress." It is often referred to as the Congressional Medal of Honor, though the official name of the award is simply "Medal of Honor."

Fort Wagner or Battery Wagner was a beachhead fortification on Morris Island, South Carolina, that covered the southern approach to Charleston Harbor. Named for deceased Lt. Col. Thomas M. Wagner, it was the site of two American Civil War battles in the campaign known as Operations Against the Defenses of Charleston in 1863, in which United States forces took heavy casualties while trying to seize the fort. The Union Army's second assault on Fort Wagner, the Second Battle of Fort Wagner, included African American soldiers from the 54th Massachusetts Infantry Regiment and 3rd United States Colored Infantry Regiment. Josiah T. Walls, who went on to become a United States Congressman from Florida, was one of the soldiers.
