I first set eyes on a tank towards the end of August 1916. At this time I little thought that I should eventually be honoured by becoming the Chief General Staff Officer of the Tank Corps, for a period extending from December 1916 to August 1918. The time spent during this long connection with the greatest military invention of the Great War, it is hoped, has not been altogether wasted, and the story here set forth represents my appreciation of having been selected to fill so intensely interesting an appointment.
Besides having witnessed and partaken in many of the events related, those who have assisted me in this book have all been either closely connected with the Tank Corps or in the Corps itself, they one and all were partakers in either the creation of the Corps or in the many actions in which it fought.
