What country defeated Napoleon Bonaparte?

Napoleon was ultimately defeated at Waterloo in 1815 by the British with the (not inconsiderable) aid of Prussia. However this does nothing to mention what had happened at Wagram, Aspern-Essling, Borodino or Leipzig & elsewhere in previous times & in previous campaigns. Indeed many of Wellingtons allied forces at Waterloo had fought for Napoleon in previous years. Napoleon had run out of friends on the battlefield. No Saxons, Bavarians, Wurttembergers to do his bidding any more. Britain had been constant in opposition, but it was the loss of his continental allies which made the difference.
