Question

Why was Fort Sumter of strategic importance to the North and the South?

Answer 1

North: They had troops, guns, equipment, and provisions inside, and they owned it, and so they wanted to keep it.
South: It was located in the South, and they thought it was rightfully theirs, and that is why they wanted it

It didn't really have any strategic importance, however, it had political importance


hope this helps

Answer 2

The North had many thing inside the fort that was all there stuff.

The South had technical ownership over the fort itself so they wanted/ needed to keep that ownership.
