What did British hope to achieve by a blockade of American ports?

The British hoped to weaken the American economy and diminish its ability to sustain the Revolutionary War effort by implementing a blockade of American ports. By cutting off trade and supplies, they aimed to limit access to crucial resources, thereby undermining the Continental Army and discouraging support for independence. Additionally, the blockade sought to isolate the colonies from potential foreign aid, particularly from France, which could bolster American resistance against British rule.
