The Hundred Days by Patrick O'Brian
Napoleon has escaped from Elba - the Hundred Days have begun. The war is over, the armies dispersed, and the former Emperor of the French has been consigned to a Mediterranean island, yet now he is marching again on Paris with an ever-growing army. Commodore Jack Aubrey and his convoy are tasked with destroying enemy shipyards along the Adriatic coast and cutting off the financial support from that quarter, in a fast and furious race to stop the Corsican from regaining all he's lost.
All is to play for and everything is at stake.
