"Captain Keene has made an interesting contribution to the literature of the present war in his account of service, which covers the experience of a young officer in the making and on the battle front, --the transformation of an artist into a first-class machine-gun officer. He covers the training period at home and abroad and the work at the front. This direct and interesting account should serve to bring home to all of us an appreciation of how much has to be done before troops can be made effective for modern war." LEONARD WOOD, Maj.-Gen. U.S.A.
