This is arguably the best biography of the militay career of Wellington ever written. It folows the development of Arthur Wellesley from an awkward and uncomfortable, untrained young officer through his growth and development in India and the Peninsula War, to his final conquest of Napoleon at Waterloo. The battles are well researched and well presented, providing a fascinating review of warfare of that era.
The book however, is not merely an account of Wellington's military success, but examines the personal life as well and with a far greater insight into his personality than most other biographies, often contradicting the usual portrayal of the man as a cold and unemotional leader.
If you can get hold of a copy ot this book, read it. You will not be disappointed.
