Query: Fascinating and Fun

Cornwell's mastery of historical detail and his deep knowledge of the military organization, weaponry, tactics and strategy of the Napoleonic era never disappoint and Sharpe's Havoc is no exception. Set during the Peninsular War, the background provides the perfect setting for Cornwell to do what he does best: weave a gripping character-based narrative into the dramatic, pitched battles that defined the era. A thoroughly enjoyable read.
