Economic war.

Explanation:

Napoleon aimed to force Britain to be willing to make peace on his terms because he forced an economic blockade known as the Continental System against the United Kingdom. The embargo did not cause major damages to the UK economy.

The Continental System

Explanation:

The Continental System, or Continental Blockade, was a policy implemented by the French emperor Napoleon against the United Kingdom during the Napoleonic Wars (1803-1815). After France defeated the Holy Roman Empire, Austria, Russia, the United Kingdom and their allies during the War of the Third Coalition (1803-1806), The United Kingdom enforced a naval blockade of France and French-aligned states. Imperial France didn't have a fleet powerful enough to challenge the might of the British Navy, so Napoleon reacted by enacting the Berlin decree of November 1806, which imposed a full embargo against British products all along French-controlled Europe. The purpose of this embargo, known as the Continental System, was to choke the British economy, as the United Kingdom was very reliant on foreign trade. Napoleon hoped that the embargo would force the British to negotiate on his own terms, or face economic collapse. However, while exports from the United Kingdom to Europe dropped by as much as 50%, the Continental System caused little damage to the British economy. For Napoleon, his attempts to enforce the continental system was one of the reasons behind his invasion of Russia, which eventually would become a major reason for his downfall.
