with what was paid them.  Jefferson decided to put an end to this tribute paying.  He sent a few ships to seize the pirates and shut up their harbors.  More and more vessels were sent, until at last the Deys and Beys and Pachas thought it would be cheaper to behave themselves properly.  So they agreed to release their American prisoners and not to capture any more American ships (1805).  In these little wars American naval officers gained much useful experience and did many glorious deeds.  Especially Decatur and Somers won renown.

248.  America, Britain, and France.—­Napoleon Bonaparte was now Emperor of the French.  In 1804 he made war on the British and their allies.  Soon he became supreme on the land, and the British became supreme on the water.  They could no longer fight one another very easily, so they determined to injure each other’s trade and commerce as much as possible.  The British declared continental ports closed to commerce, and Napoleon declared all British commerce to be unlawful.  Of course under these circumstances British and Continental ships could not carry on trade, and American vessels rapidly took their places.  The British shipowners called upon their government to put an end to this American commerce.  Old laws were looked up and enforced.  American vessels that disobeyed them were seized by the British.  But if any American vessel obeyed these laws, Napoleon seized it as soon as it entered a French harbor.

249.  The Impressment Controversy.—­With the British the United States had still another cause of complaint.  British warships stopped American vessels and took away all their seamen who looked like Englishmen.  These they compelled to serve on British men-of-war.  As Americans and Englishmen looked very much alike, they generally seized all the best-looking seamen.  Thousands of Americans were captured in this way and forced into slavery on British men-of-war.  This method of kidnaping was called impressment.

250.  The Embargo, 1807-1809.—­Jefferson hardly knew what to do.  He might declare war on both Great Britain and on France.  But to do that would surely put a speedy end to all American commerce.  In the old days, before the Revolutionary War, the colonists had more than once brought the British to terms by refusing to buy their goods (pp. 84, 85).  Jefferson now thought that if the people of the United States should refuse to trade with the British and the French, the governments both of Great Britain and of France would be forced to treat American commerce properly.  Congress therefore passed an Embargo Act.  This forbade vessels to leave American ports after a certain day.  If the people had been united, the embargo might have done what Jefferson expected it would do.  But the people were not united.  Especially in New England, the shipowners tried in every way to break the law.  This led to the passing of stricter laws.  Finally the New Englanders even talked of seceding from the Union.
