What happened in the battle of fort sumter? and in the battle of bull run .

I can’t help with the battle of fort Sumter:

The intense Confederate artillery bombardment of Major Robert Anderson's small Union garrison in the unfinished fort in the harbor at Charleston, South Carolina, had been preceded by months of siege-like conditions.

This is basically the key events and what happened in this battle. Hope it helped a bit. God bless and good luck!!
