How many soldiers were killed at Fort Sumter at the start of the American Civil War?

The Battle of Fort Sumter (April 12–14, 1861) was the bombardment and surrender of Fort Sumter, near Charleston, South Carolina, that started the American Civil War. Following declarations of secession by seven Southern states, South Carolina demanded that the U.S. Army abandon its facilities in Charleston Harbor.

There were no (zero) casualties during the Confederate bombardment of Fort Sumter at the start of the American Civil War. The only Union deaths came during the evacuation: One soldier was killed and another mortally wounded in an accidental explosion during a planned 100 gun salute.

After the surrender of Fort Sumter, South Carolina authorities then seized all Federal property in the Charleston, South Carolina area. This was also quickly done without anyone being killed.
