Sharpe's Revenge: The Peace of 1814 (The Sharpe Series, Book 19) by Bernard Cornwell
Richard Sharpe and the Peace of 1814.
It is 1814. There are rumours that Napoleon is dead, or has run away, but Sharpe has one last, battle to fight before he can lay down his sword - it is the battle for Toulouse. Little does he know it will be one of the bloodiest conflicts of the war.
But Sharpe's war is not only the battle. Accused of stealing Napoleon's treasure, Sharpe must discover the unknown enemy who has tried to frame him - and his revenge is ingenious and devastating.
Soldier, hero, rogue - Sharpe is the man you always want on your side. Born in poverty, he joined the army to escape jail and climbed the ranks by sheer brutal courage. He knows no other family than the regiment of the 95th Rifles whose green jacket he proudly wears.
