I personally believe that it was the power of money that defeated Napoleon. Britain dominated world trade. She was already a hundred years into the Industrial Revolution and these two provided her with the funds to build a truly colossal fleet to keep herself safe from invasion, safeguard all her worldwide trade routes and become the paymaster of all the European monarchies opposed to the ideals of Revolutionary France. French battlefield techniques remained superior to those of any other of the European powers, including ourselves, just as the Nazis were in World War Two; but just as in that war the underdogs got better so that their combined material and numerical numbers eventually proved decisive.
I think also there is a strong case for arguing that we made an end of Napoleon on the remote, South Atlantic island of St. Helena, his final place of exile. Crimes need three ingredients: means, opportunity and motive. We had all three. It was a healthy Napoleon who arrived at the island at the age of forty-seven. Six years later he was dead.
First, as our prisoner, we obviously had the means and opportunity. Finally – in my view the decisive factor – his incarceration was costing us a fortune. On that small island of ten miles by six we felt it necessary to garrison 2,000 troops. Second we also felt it necessary to maintain two ships of the line on permanent duty sailing round the island.
The final and perhaps decisive factor influencing the British government of the day was the nightmarish fear that France – which bounced back strongly after Waterloo – would mount a rescue operation to rescue their humiliated hero and begin the Napoleonic Wars all over again.
