Wellington, The Years of the Sword by Elizabeth Longford.
"In the first volume Elizabeth Longford covers his (the Iron Duke's) martial life that ended abruptly, when he was a handsome resilient forty-six, in the holocaust of Waterloo. After Waterloo, Wellington was never asked to fire another shot.
This first volume shows the sensitive, withdrawn child of Irish aristocrats pushed into the army as 'food for powder', stumbling his way through the Flanders field , an abortive love affair, and the roistering banquet halls of Dublin Castle to reach India at twenty-seven. There he made his name and, as Sir Arthur Wellesley, returned to England and marriage to Kitty Pakenham ...etc."
I read this biography with great enjoyment and will consult it while writing my new novel, Monday's Child, the sequel to Sunday's Child published by MuseItupPublishing.
