Editorial cartoon concerning the Embargo Act of 1807. The Embargo Act was arguably Jefferson's worst move as a president and was one of the nation's great foreign policy disasters. Admittedly, the U.S. was not bargaining from a strong position. But still, Jefferson really wasn't a very effective president.
As for the specifics of the cartoon, I'm not sure what it all means. Pre-Civil War editorial cartoons are full of extremely obscure insider references.
