Continental SystemThe Continental Blockade (Blocus continental), or Continental System, was a large-scale embargo by Napoleon Bonaparte against the British Empire from 21 November 1806 until 11 April 1814, during the Napoleonic Wars. Napoleon issued the Berlin Decree on 21 November 1806 in response to the naval blockade of the French coasts enacted by the British government on 16 May 1806. The embargo was applied intermittently, ending on 11 April 1814 after Napoleon's first abdication.
Battle of UlmThe Battle of Ulm on 16–19 October 1805 was a series of skirmishes, at the end of the Ulm Campaign, which allowed Napoleon I to trap an entire Austrian army under the command of Karl Freiherr Mack von Leiberich with minimal losses and to force its surrender near Ulm in the Electorate of Bavaria. In 1805, the United Kingdom, the Austrian Empire, Sweden, and the Russian Empire formed the Third Coalition to overthrow the French Empire. When Bavaria sided with Napoleon, the Austrians, 72,000 strong under Mack, prematurely invaded while the Russians were still marching through Poland.
