"Eagles Last Triumph" is an outstanding treatment of the Waterloo Campaign, with special focus on the battle of Ligny, 2 days prior to the more commonly known battle of Waterloo. Uffindell counts on a variety of primary and secondary sources. Nor does he depend heavily on British accounts; German, French and Dutch-Belgian sources are used as well, balancing the writing so that the reader can understand the why of the decisions made by the battlefield commmanders. There are maps, though not many of them, but clear and relevant to the accounts in the book. His after-battle analysis, leading to the impact the twin battles of Quatre-Bras and Ligny had 2 days later on their more famous cousins, Waterloo and Wavre, is excellent. Through it, you may (as I have) come away convinced that Ligny, though a French tactical victory, was a strategic defeat in that it was the best chance in the campaign for Napoleon to destroy one of the armies he faced during the campaign. If the Prussian army had been destroyed at Ligny, Waterloo would not have been fought. Strongly recommended for all readers.
