What did T. E. Lawrence (1888-1935) read at Oxford and in Arabia? Well, according to him:
I had read the usual books (too many books), Clausewitz and Jomini, Mahan and Foch, had played at Napoleon’s campaigns, worked at Hannibal’s tactics, and the wars of Belisarius, like any other man at Oxford; but I had never thought myself into the mind of a real commander compelled to fight a campaign of his own….
As I have shown, I was unfortunately as much in command of the campaign as I pleased, and was untrained. In military theory I was tolerably read, my Oxford curiosity having taken me past Napoleon to Clausewitz and his school, to Caemmerer and Moltke, and the recent Frenchmen. They had all seemed to be one-sided; and after looking at Jomini and Willisen, I had found broader principles in Saxe and Guibert and the eighteenth century. However, Clausewitz was intellectually so much the master of them, and his book so logical and fascinating, that unconsciously I accepted his finality, until a comparison of Kuhne [?] and Foch disgusted me with soldiers, wearied me of their officious glory, making me critical of all their light. In any case, my interest had been abstract, concerned with the theory and philosophy of warfare especially from the metaphysical side….
I had made a comfortable beginning of doctrine, but was left still to find an alternative end and means of war. Ours seemed unlike the ritual of which Foch was priest; and I recalled him, to see a difference in land between him and us. In his modern war—absolute war he called it—two nations professing incompatible philosophies put them to the test of force. Philosophically, it was idiotic, for while opinions were arguable, convictions needed shooting to be cured; and the struggle could end only when the supporters of the one immaterial principle had no more means of resistance against the supporters of the other. It sounded like a twentieth-century restatement of the wars of religion, whose logical end was utter destruction of one creed, and whose protagonists believed that God’s judgement would prevail. This might do for France and Germany, but would not represent the British attitude. Our Army was not intelligently maintaining a philosophic conception in Flanders or on the Canal. Efforts to make our men hate the enemy usually made them hate the fighting. Indeed Foch had knocked out his own argument by saying that such war depended on levy in mass, and was impossible with professional armies; while the old army was still the British ideal, and its manner the ambition of our ranks and our files. To me the Foch war seemed only an exterminative variety, no more absolute than another. One could as explicably call it ‘murder war’. Clausewitz enumerated all sorts of war…personal wars, joint-proxy duels, for dynastic reasons…expulsive wars, in party politics…commercial wars, for trade objects…two wars seemed seldom alike. Often the parties did not know their aim, and blundered till the march of events took control. Victory in general habit leaned to the clear-sighted, though fortune and superior intelligence could make a sad muddle of nature’s ‘inexorable’ law.
