F. C. FULLER WITH 8 PLATES LONDON KEGAN PAUL, TRENCH, TRUBNER & CO., LTD. NEW YORK: E. P. DUTTON & CO. _Printed in Great Britain by_ MACKAYS LTD., CHATHAM PREFACE The first part of this little book, namely “The Battle of the Iron Horse,” appeared, very much as it stands, in the September number of _The National Review_, 1925, and I have to thank the editor, Mr. Leo Maxse, for his kindness in allowing me to republish it. The second part is based partially on personal experience and reflection, and partially on the lectures and papers of others. In the war, the tank brought me to realize the enormous possibilities of cross-country movement, and, in 1921, I set down my ideas as regards its commercial future in a pamphlet entitled _Economic Movement_, which was published in 1922. Of the works of others, I have borrowed ideas from the following:— “Improvements in the Efficiency of Roadless Vehicles.” A paper read before the members of The Institution of Automobile Engineers, by Colonel P. H. Johnson, C.B.E., D.S.O., December, 1921. “Multi-Wheel and Track Motor.” A paper read before the members of the above Institution by Major T. G. Tulloch, March, 1923. “The Progress of Mechanical Engineering in the Military Service.” A lecture delivered before the members of The Institution of Mechanical Engineers, by Major G. le Q. Martel, D.S.O., M.C., January, 1924. “Transport in Tropical Africa.” A paper read before the members of The Royal Society of Arts, by Mr. R. H. Brackenbury, February, 1925. “The Roadless Transport Problem.” A paper read before the members of The British Association, by Colonel P. H. Johnson, C.B.E., D.S.O., August, 1925.
