Britain continues to trade for and buy 90% of its hemp directly from Russia.
Napoleon and Czar Alexander of Russia sign the Treaty of Tilset, which cuts off all legal Russian trade with Great Britain, its allies, or any other neutral nation ship acting as agents for Great Britain in Russia.
The treaty also sets up a buffer zone, the Warsaw Duchy (approximately Central Eastern Poland) between Napoleon’s allies and Russia.
The United States is considered a neutral country by Napoleon, as long as its ships do not trade with or for Great Britain, and the United States considers itself to be neutral in the war between France and Great Britain.
However, Congress passes the 1806 Non-Importation Pact: British articles which are produced in the U.S., but which could be produced elsewhere, are prohibited. Congress also passes the 1807 Embargo Act, to wit: American ships could not bring or carry products to or from Europe.
These laws hurt America more than Europe; however, many Yankee traders ignored the law anyway.
Hence, any ship that trades with Napoleon’s “Continental System” of allies is the enemy and is subject to blockade.
On this pretext, Britain confiscates American ships and cargo and sends sailors back to the United States at American ship owners’ expense.
Britain “impresses” some American sailors into service in the British navy. However, England claims that they only “impress” those sailors who are British subjects – and whose American shipping companies refused to pay for the sailors’ return fares.
