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 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 studied as carefully as a campaign free from error. From history we obtain experience, and experience teaches us how to act for the future. We learn how great men of old time fought their battles and managed their retreats; we see the reasons of their successes and their failures; and we should endeavour to make use of our lessons when our own time comes. Not that Grouchy can be deemed a great soldier; nor can his part of the 1815 campaign be regarded as of prime importance in itself; but as showing the small trifles that mar great plans in their execution, as showing how little a thing will sometimes destroy the grandest conceptions, his operations from 16th June to the end of the month are well worthy of attention.

I might have employed my time more profitably had I chosen to work upon some more illustrious name than Grouchy’s, or upon some more modern campaign of greater advantage to the war student of to-day; but I chose to bring forward an obscure page in the history of the most famous campaign, for in that history there is much that may still be laid to heart.

Great deeds deserve great critics, but, as Colonel Henderson wrote in his Preface to “Stonewall Jackson,” “if we were to wait for those who are really qualified to deal with the achievements of famous captains, we should, as a rule, remain in ignorance of the lessons of their lives, for men of the requisite capacity are few in a generation.” Man is not so fortunate that he can live in every period; and for knowledge he must go backwards to search in history. The statesman will read of the great quarrels between Charles I. and his Parliament, not because he would imitate either the one side or the other, but because he will desire to mould future action upon the experience of the past. Napoleon himself prepared all his ambitious schemes from the pages of Tacitus, Plutarch and Livy, and the histories of the deeds of Hannibal, Alexander, and CÆsar. Wellington “made it a rule to study for some hours every day”; and since these two great men advocate study of history, who is there who shall gainsay the advantages of learning? But the true method of reading history requires something far deeper than mere perusal: it must be accompanied by careful and continuous thought. A true history will encourage the reader to bury himself in the very atmosphere of the time, and will bring him to see with his eyes the comings and goings of great men, the rights and wrongs of their deeds, and their impress upon contemporary people.

This small volume attempts nothing of this kind: it is a sketch, a mere outline, of a minor portion of a remarkable campaign. In it I have made no mention of the tactical formations employed; I have given no details of armaments, equipments, or means of transport; for these are now of no value to the soldier-student. The comments or remarks are to be taken or left, as it shall please the reader: they are my own views; possibly they may coincide with the views of others; in that case they will be interesting.

I may admit that these pages were at first written for my own use—mere notes taken down while I read a dozen authorities on the subject. I afterwards persuaded myself that my studies might prove of use to those who had little time to search the volumes in the libraries.

I trust I shall not offend German susceptibilities by omitting the prefix “von” in the Prussian names and titles. I only do so to save space.

I have to add my gratitude to the numerous writers and historians who have told the splendid story of Waterloo, and from whom I have drawn my facts.
