“Extraordinary times produced an extraordinary man,” Michael Broers writes in the third and final volume of his extraordinary biography of Napoleon Bonaparte, the emperor who modernized Europe by military skill, technocratic order and the force of his personality. All three of these assets had their limits, and all three became liabilities. Mr. Broers’s second volume ended in 1810, with Napoleon’s power at its zenith. This third volume describes the decline and fall of the modern Caesar.
