In the autumn of 1916 I was asked by the Union Government to undertake the official History of the South African Forces in Europe. At the time I was serving in France, and had therefore an opportunity to see something of the Infantry Brigade. For various reasons I was unable to begin the work until after the signing of the Armistice: since which date I have had at my disposal all official papers, and have received the assistance of many South African officers. I desire to express my gratitude to Major-General Sir H. T. Lukin, Brigadier-General Dawson, Brigadier-General Tanner, and the various battalion and battery commanders for the help they have given me. I would especially thank Major H. P. Mills of the Third Regiment, but for whose unwearying co-operation the book could not have been written. My aim has been to tell as simply as possible the story of a great military achievement, to my mind one of the finest in the whole history of the campaigns; and, at the same time, to provide a detailed account of the operations of the infantry and the other services, which, I trust, may be of interest as a war record both for the men who fought and for the country which sent them forth.
