Union's naval supremacy and blockade of Southern ports.
Blockade
To blockade the Southern ports.
TO blockade southern ports
By organising a system of blockade-runners. (See 'Gone with the Wind'.)
The original Anaconda Plan did call for, in part, a blockade of Confederate ports on its east and southern coasts. The blockade's effectiveness is disputed by historians. Much of the South's in and out shipping was able to run past the blockade by cover of night. Also, as the coastlines were huge, there could not be a total 100% blockade. It did, however, stop many ships from sailing into Southern ports.
