Why was napolaen inable to invade great Britain?

Answer 1

Napoleon was unable to invade Britain because he was unable to transport his army the 21 miles, (34km), from France to England, across the English Channel. He had the ships, but they were scattered across various ports in Western Europe and to assemble them in the correct place meant possible interception from the British Royal Navy. This happened on 21st October 1805 off Cape Trafalgar when 27 British ships-of-the-line intercepted 33 similar French and Spanish vessels. In the ensuing battle 22 Franco-Spanish ships were lost without a single British loss.
