"The three lectures here published are the Lees-Knowles Lectures in Military History for 1929-30, delivered at Trinity College, Cambridge, in the spring of this year...The two matters which may perhaps claim some novelty, the evolution of the great war-horse and of the Hellenistic great ships, are now rather more fully treated, chiefly by means of notes and appendices; indeed, the principal justification for the appearance of these lectures in book form must be the section on the ships, about which comparatively little has hitherto been written to much purpose." - Preface.
