“I am not surprised,” was Saint-Loup’s comment; “for he’s a sensible man. But in spite of that he is blinded by the prejudices of his caste, and above all by his clericalism. Now,” he turned to me, “Major Duroc, the lecturer on military history I was telling you about; there’s a man who is whole-heartedly in support of our views, or so I’m told. And I should have been surprised to hear that he wasn’t, for he’s not only a brilliantly clever man, but a Radical-Socialist and a freemason.” Partly out of courtesy to his friends, whom these expressions of Saint-Loup’s faith in Dreyfus made uncomfortable, and also because the subject was of more interest to myself, I asked my neighbour if it were true that this major gave a demonstration of military history which had a genuine aesthetic beauty. “It is absolutely true.” “But what do you mean by that?” “Well, all that you read, let us say, in the narrative of a military historian, the smallest facts, the most trivial happenings, are only the outward signs of an idea which has to be analysed, and which often brings to light other ideas, like a palimpsest. So that you have a field for study as intellectual as any science you care to name, or any art, and one that is satisfying to the mind.” “Give me an example or two, if you don’t mind.” “It is not very easy to explain,” Saint-Loup broke in. “You read, let us say, that this or that Corps has tried ... but before we go any farther, the serial number of the Corps, its order of battle are not without their significance. If it is not the first time that the operation has been attempted, and if for the same operation we find a different Corps being brought up, it is perhaps a sign that the previous Corps have been wiped out or have suffered heavy casualties in the said operation; that they are no longer in a fit state to carry it through successfully. Next, we must ask ourselves what was this Corps which is now out of action; if it was composed of shock troops, held in reserve for big attacks, a fresh Corps of inferior quality will have little chance of succeeding where the first has failed. Furthermore, if we are not at the start of a campaign, this fresh Corps may itself be a composite formation of odds and ends withdrawn from other Corps, which throws a light on the strength of the forces the belligerent still has at his disposal and the proximity of the moment when his forces shall be definitely inferior to the enemy’s, which gives to the operation on which this Corps is about to engage a different meaning, because, if it is no longer in a condition to make good its losses, its successes even will only help mathematically to bring it nearer to its ultimate destruction. And then, the serial number of the Corps that it has facing it is of no less significance. If, for instance, it is a much weaker unit, which has already accounted for several important units of the attacking force, the whole nature of the operation is changed, since,
