Blockade

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.
