Historians have often argued among themselves and at times have taken the people into their confidence with regard to the great battles of history, and so well have they done what they have undertaken, describing and comparing the battle-scenes, fighting over again the great struggles, and explaining the causes and the epoch-making results of Marathon, Philippi, Hastings, Waterloo, Gettysburg, and the rest, that a layman like myself in such historical studies as theirs must not trespass on their territory.

But in human history there are battle-fields and battle-fields and at no serious risk of encroaching on any expert's preserves I have chosen from history five battles that I know to be great, indeed that I am almost ready to declare the very greatest, and that I think I can show to be in the fullest sense epoch-making. The scenes of these battles I would visit in this essay. Before setting out, since the journey is hardly an ordinary one, being very like a journey in wonderland or at least being in a world the geography of which no geographers known to me have ever mapped or described, I must try to show, at least in a general way, in what sort of a world the various battles of this essay have been fought to their finish.

The spiritual values, not alone, but added to the physical
