As for "fought outnumbered yet achieved crushing victories", it's worth remembering that Britain had allies nearly throughout the war: Portuguese and Spanish during most of the Peninsular War; Germans (and Dutch) at Waterloo, and most of the time the Russians and Austrians fighting the French with whatever success to the east.
I'm just getting stuck into Robert's "Napoleon the Great", my Christmas present to myself!
At Austerlitz, Britain paid money for each dead Russian soldier. English agents were busy counting the dead making sure his majestry's money is well spent while French medics trying to save wounded from both side. Austrian emperor Francis allegedly said 'English are merchants of human flesh.
Also, Britain routinely paid other monarchies to have them send their soldiers. They hired Germans to fight against American independence. George Washington's famous first victory was crossing the Delaware river and surprise attacked what were actual German legions.
