There were three very important forts that protected large and crucial cities. Two of three were guarded with southern cities. They switched their beliefs and joined the confederate states. However, the last one Fort Sumter refused. This fort was one of the few protected by people from the North.
unfortunately, for fort Sumter there was a mini island bordering Charleston which, was one of the the biggest cities in the US. The mini island was surrounded by the other 2 forts which were owned by the Confederates. The Confederates could easily resupply due to the two forts near Fort Sumter.
Jefferson Davis, the new President of the Confederate States, had taken siege on Fort Sumter. He had expectations that the soldiers inside would either surrender or die.
I will send an unarmed ship with supplies to my fort! It is still US territory. I will send a letter to Jefferson Davis to tell him it is an unarmed ship and is to be unharmed!
Jefferson Davis made a decision. Here in Fort Sumter, was where the first shots of the Civil War were shot!
Abraham Lincoln left Jefferson Davis with only 3 options, none of which looked good. The first one was to take down the fort, which would lead to the start of the Civil War. The second one was to let the ship pass. Lastly, they could shoot at the ship which would be horrible because they would be shooting at an unarmed US ship which would also start a war.
