What was blockade runing?

Answer 1

A good example of a blockade occurred during the Civil War. The North knew that the South had limited resource, with almost no manufacturing plants and much of its land devoted to cash crops such as cotton rather than to growing food. The North also had more ships than the South. They sent their warships to cluster near the ports of the South so that they could attack and capture or destroy any ships trying to enter the port. The South desperately needed cannons and other arms, as well as clothing and coffee and everything in between. "Blockade running" was trying to sail into the ports with needed merchandise unnoticed by the enemy warships, a difficult and dangerous job.
