How did the blockade that the north placed on the southern ports?

The blockade that the North imposed on Southern ports during the Civil War was a crucial strategy to weaken the Confederacy's economy. By cutting off access to international trade, the South struggled to export cotton and import necessary supplies, leading to shortages and inflation. This naval blockade effectively restricted the Confederacy's ability to sustain its war efforts, contributing to its eventual defeat. Overall, the blockade played a significant role in crippling the Southern economy and diminishing morale.
