On the morning of the battle of Waterloo, Napoleon declared that the Duke of Wellington was a bad general, and that France could not fail to win an easy victory. Did he misunderstand his rival? Also the author of the definitive 2014 Napoleon, Andrew Roberts examines the connections between these men, both born in 1769 and indisputably the two greatest generals of their era. Behind closed doors, Napoleon praised his English foe, while Wellington publicly lauded Napoleon and even saved him from execution after Waterloo. In private, Wellington had his doubts about the emperor's military prowess, but as Roberts reveals, shared his taste in women.
