Answer: When South Carolina forced the surrender of Fort Sumter.
Step-by-step explanation:
This event is also taken as the official start of the Civil War. For more than thirty hours, the Confederacy bombed Union forces that eventually surrendered Fort Fort Sumter in Charleston Harbor, South Carolina. So the real war activity in the civil war resulted in the rebels winning. This turnout contributed to the secession of South Carolina. One of the darkest periods in American history is about to begin.
