What happened after the Battle of Trafalgar?

After the Battle of Trafalgar, which took place in October of 1805, it is what did not happen that may be most significant. With the loss of his battle-fleet to the British off the Cape of Trafalgar, Napoleon did not (and could not) engage in any invasion of Great Britain, since British ships still controlled the seas. However that may be, the victory cemented the reputation of the British navy as foremost among modern nations and contributed to Great Britain's ongoing resistance to the aggressions of Napoleonic France.
