Just a change of focus here. I am interested to understand why Britain sought to get involved in the wars on the continent, and over turn the revolution and reinstall a king to the throne. Britain vehemently opposed revolutionary France and Napoleon. Was this a series of wars that they really needed to fight, or were they just on an old fashioned imperialist quest for power and empire trying to bring down a potential rival so they could have a free hand around the world?
I can see that there was a point after 1805 when Britain feared a French invasion, but this was largely in response to the consistent belligerence of the British forming new alliances, encouraging new armies and coalitions against France, and the tearing up of the Treaty of Amiens.
I am also curious as to why the British and the Prussians felt that they had to fight Napoleon again in 1815 after his return to power? Napoleon wasn't fixing for a fight as far as I know. In fact France was tired of war. France was no longer occupying vast swathes of Europe either. What was really at stake?
