March 22, 1806
The situation in Europe was quite more difficult than expected with the rise of Napoleon Bonaparte to power, but it somehow played a great role in the relationship between the U.S. and Great Britain. John Breckinridge informed in a letter to Henry Clay that Bonaparte signed a peace treaty with the emperors of Germany and Russia, through the marriage of Eugene Beauharnais and the daughter of the Elector of Bavaria. On December 26th 1805, Napoleon had additionally forced Austria to sign the Treaty of Pressburg, with no attempt to include Great Britain or Russia in the treaty. Breckinridge was convinced that this event would play in favor of the U.S. Government in the difficulties between them and the Royal Crown of England.
