A commercial blockade has no immediate military objective but is designed to cause the enemy to surrender or come to terms by cutting off all commercial intercourse by sea.

Detailed explanation-2: -A blockade is a military operation that blocks all maritime movement to or from a port or coast. Blockades may also be aerial. A military operation carried out on land that isolates or encircles an area is called a siege.

Detailed explanation-3: -A blockade differs from an embargo or sanction, which are legal barriers to trade rather than physical barriers. It is also distinct from a siege in that a blockade is usually directed at an entire country or region, rather than a fortress or city and the objective may not always be to conquer the area.
