What john paul Jones do that are so important?

John Paul Jones secured the exchange of British captives for the freedom of American prisoners of war. He also captured a British ship carrying uniforms, winter clothes, and provisions to British soldiers in America, thus depriving them of necessary equipment and aiding the Americans.

In addition to this, Captain Jones developed the war tactic of attacking the enemy's home country so they will focus their attention on saving their country and not so much on attacking the American coasts. In fact, Captain Jones was the first person to attack England with a warship since the Vikings first came there.
