Hitler tried to stop the flow of supplies to England by destroying the convoys of supply ships. He deployed u boats (submarines) with torpedoes to hunt and sink the ships. When he deployed several u boats hunting as a team these were known as wolf packs.
German submarines that hunted in "wolf packs" disrupted the flow of supplies and soldiers to Britain.
Clearing the Atlantic shipping lanes from the threat of Nazi U-boats and raiders allowed the flow of supplies and personnel to England for the buildup in preparation for the invasion of Europe.
To surround him with enemy forces and cut off supplies in an attempt to capture a city is called a siege. This military tactic involves isolating the target to prevent the flow of resources, thereby weakening the defenders and making it easier to take control of the location. Sieges can last for extended periods and often involve both direct attacks and psychological warfare.
