A
blockade was an operation in which a hostile army seized and maintained control
of the most important avenues of approach leading to a place for the purpose
of intercepting traffic into and out of the place. Blockades could be conducted
by land or by sea. When conducted by land forces the hostile army established
posts on all of the important roads and routes leading to the blockaded place
and in all of the significant towns and villages near the place to prevent
of supply convoys from getting into the place and inhibit communication with
forces outside of the place. When a blockade was conducted by sea hostile
warships were stationed near harbor channels to intercept or impede shipping
attempting to enter or depart the harbor. Unlike an investment, there was
no attempt to completely surround the fortified place and cut off all of
its communications; blockades were generally conducted with the minimum number
of troops or ships necessary to intercept and prevent a large volume of traffic
into and out of the place. |
