John Bull backed up against a tree and being hacked to pieces by a horde of malevolent pygmies. An American gunboat is to the left manned by three disreputable-looking sailors and flying a tattered Stars & Stripes and the pennant of the frigate USS President. As an enraged British bull-dog barks at them, the American captain fires a swivel gun at John Bull's right leg. At far left Napoleon cheerfully sits in front of his tent, his right foot resting on a globe. The title refers to the Congress of Prague (June 4-August 10, 1813) at which Metternich attempted in vain to negotiate a peace between Napoleon and the Allies.
