Civil War's First Shot

Fort Sumter was first held by the Union Army (OK, they snuck over there with 80 men and only a few working cannon).  Because it was smack in the middle of Charleston Harbour, this infuriated the citizens of Charleston - who were die-hard Southerners.  There were armed Batteries on all shores.  At 4:00 in the morning, the first shot was fired.  The Confederates opened fire on all sides.  The union had ships sitting 2 miles out with supplies, men and more cannon, but they couldn't get in.  After 2 straight days of non-stop firing, the Confederates allowed the Union to leave.  The union won it back 3 years later and held it until the end of the war.
