The Civil War and its aftermath produced many interesting and significant characters, probably more so than in any other period of history. Most of these men (and some women) are now unfortunately forgotten. Barrister Geoffrey Robertson recently corrected this with his excellent - and probably the first - biography of John Cook, the barrister who led the prosecution case against Charles I. That book is particularly significant because the reader could fully understand the life of John Cook with little or no previous knowledge of the historical background, surely quite an achievment by the author. Yorkshireman John Lambert was probably the best leader we never had and it is curious that this is only the second biography of him to appear, the first being long unavailable. This is a very well reseached and referenced book and the author has written a very full life of Major General Lambert. However this book would be very difficult to follow by someone who did not have quite a deep knowledge of the rather complicated history of the period as well as that of the geography of the British Isles, as the book contains no maps. Also the constant reporting of the opinions of others, making it read like a textbook of physiology, is not helpful in the general flow of the book. A good question to ask about a book is 'at whom is it aimed?' This is easily answered in this particular case: it is aimed at the academic but certainly not at the general reader.
