In the American Revolutionary war and the Napoleonic Wars, the SLOCs were for the most part, in the control of the British Navy—when the British lost control of them during the Revolution, the result was the loss of Yorktown and its biggest army, and ultimately the war. In the Napoleonic era, maintaining belligerence throughout, the British embargoed and blockaded any country associated with Napoleon, creating large economic hardships and dislocations that ultimately led to the people of France becoming disenchanted with their Emperor.
