Waterloo: The History of Four Days, Three Armies and Three Battles is a history book written by Bernard Cornwell, first published in Great Britain by William Collins on 11 September 2014, and by Harper Collins Publishers on 5 May 2015 in the United States. It is Cornwell's first work of nonfiction, after publishing more than forty novels in the historical fiction genre, including the popular Richard Sharpe series taking place during the Napoleonic Wars. The book recounts the Battle of Waterloo on 18 June 1815, including preceding events from the campaign of the same name and The Hundred Days. According to the book's jacket, the book was commissioned to commemorate the Battle's 200th anniversary.The book includes a number of full colour illustrations, including maps and colour portraits of the major figures involved, including Napoleon Bonaparte, the Duke of Wellington, Field Marshall Prince von Blucher, Marshalls Ney, Soult and Grouchy. The book should not be confused with Cornwell's novel Sharpe's Waterloo, originally published as Waterloo in 1990. That novel also narrates the battle, but largely from the perspective of Cornwell's fictional characters. Source: Wikipedia (en)
