Independent scholar Adams introduces readers to Cuthbert Collingwood (1748-1810), whose real-life adventures as commander of the British Navy provided the model for the fictional character of Jack Aubrey. Drawing upon Collingwood's personal letters, as well as ships' logs and contemporary newspaper accounts, Adams describes the daring exploits of this modest man who was beloved by officers and crew alike. Coverage includes Collingwood's central role in the defeat of Napoleon's fleet at Trafalgar. Annotation 2005 Book News, Inc., Portland, OR (booknews.com)
