The book is well researched and well written. It is the best historical account I have found for the time period in question. It provides some significant details omitted from other accounts.
The book starts with a prologue giving a description of the action between the Brig sloop Speedy, under the command of then commander Lord Cochrane, and the Spanish frigate Gamo resulting in the amazing capture of the Gamo. This is a much better account then what I found in Cochrane's own autobiography (which is surprising considering he was not known for his modesty). The book then proceeds with action starting in 1798 with Captain Sir William Sidney Smith's escape from captivity in Paris, and General Napoleon Bonaparte's descent on Egypt which resulted in the Battle of the Nile (Admiral Nelson victorious), and the defense of Acre (Captain Smith victorious - the only military setback of Napoleon on land prior to his retreat from Moscow).
The book is mainly about naval action, but includes details of some significant land campaigns starting with the aforementioned defense of Acre. It covers various actions up through 1815 including the war between England and the United States (there is a good account, for example, of the Battle of New Orleans). There is some commentary on the political situations of the time period.
There are some helpful details on other aspects of the war, including the Hot Press of 1803 when England needed to man its ships in a hurry. Men and boys were snatched off the street, out of theaters, off ships, from their jobs, etc., with no regard to their occupations, naval experience (if any) and other commitments. In some cases there were pitched battles with townsmen.
There are also some details of atrocities. The French advance up the coast from Alexandria was accompanied by the French massacre of Turkish prisoners. The Turks reciprocated in kind by torturing and beheading French prisoners. There is also an account of the deliberate massacre of American prisoners held in Dartmoor Prison in 1815, after the war had ended.
It might be noted that this was a time period when officers still led from the front, and many officers including Admirals and Generals were killed or wounded. When Admiral Nelson commanded the British fleet at the Nile, he was blind in one eye and missing an arm as the result of earlier actions.
There are some side discussion of interest, including the relationship between Admiral Nelson and Lady Hamilton. Overall it is a very good reference book for anyone studying the period. There are footnotes to various references, a listing of recommended reading, and an extensive bibliography at the end of the book. There is also an index, and the book contains various maps and illustrations.
