"So much has been written on the Waterloo Campaign that, even in the smallest details, nothing new can be revealed; but the dazzling magnitude of the great battle itself has obscured a part of the campaign which is seldom studied - the battle against Thielemann, and Grouchy's skilful [skillful] retreat from Wavre. I have chosen this tail-end of the campaign because little is known about it; because it serves useful lessons even for to-day; because the operations leading up to the battle round Wavre are of great interest; and because a campaign full of mistakes should be studies as carefully as a campaign free from error." -- From the Author's preface, page v.
