So much has been written about the great soldiers of the world, that it is a matter of considerable hardihood to attempt to present another volume on the subject in any sense "new."

The springs of history rise far back. We can the better appreciate our leaders of today and their problems, by comparing them with the leaders and problems of yesterday. Waterloo takes on a new aspect when viewed from Vimy.
