When the Flanders battle of July 31, 1917, was about to be fought, we employed the old ruse of the Chinese attack. We modernised the trick of medieval garrisons which would make a show of getting ready to break out at one gate when a real sally was to be made from another. The enemy was invited to think that a big attack was at hand. But against Lens, and not east of Ypres. Due circumstantial evidence was provided. There were audible signs that a great concentration of British guns were cautiously registering, west of Lens. A little scuffle on that part of the front elicited from our side an amazing bombardment—apparently loosed in a moment of panic. I fancy a British Staff Officer’s body—to judge by his brassard and tabs—may have floated down the Scarpe into the German lines. Interpreted with German thoroughness, the maps and papers upon it might easily betray the fact that Lens was the objective. And then a really inexcusable indiscretion appeared—just for a moment, and then was hushed up—in the London Press. To an acute German eye it must have been obvious that this composition was just the inconsequent gassing of some typically stupid English General at home on leave; he was clearly throwing his weight about, as they say, without any real understanding of anything. The stuff was of no serious value, except for one parenthetic, accidental allusion to Lens as the mark. As far as I know, this ebullition of babble was printed in only one small edition of one London paper. Authority was then seen to be nervously trying, as Uncle Toby advised, “to wipe it up and say no more about it.” Lest it should not be observed to have taken this wise precaution some fussy member of Parliament may have asked in the House of Commons how so outrageous a breach of soldierly reticence had occurred. And was there no control over the Press? It all answered. The Germans kept their guns in force at Lens, and their counter barrage east of Ypres was so much the lighter, and our losses so much the less.

If we did these things in the green leaf, what might we not do in the dry? Mobilize our whole Press, conscribe it for active service under a single control, a—let us be frank—a Father-General of Lies, the unshaming strategic and tactical lies of “the great wars” which “make ambition virtue,” and sometimes make mendacity a virtue too? Coach the whole multitudinous orchestra of the Press to carry out the vast conceptions of some consummate conductor, splendide mendax? From each instrument under his baton this artist would draw its utmost contributive aid to immense schemes of concerted delusiveness, the harping of the sirens elaborated into Wagnerian prodigies of volume and complexity.
As you gaze from the top of a tree or a tower behind your own front, in a modern war, all the landscape beyond it looks as if man had perished from the earth, leaving his works behind him. It all looks strangely vacant and dead, the roofs of farms and the spires of churches serving only to deepen your sense of this blank deletion of man, as the Roman arches enhance the vacuous stillness of the Campagna. Your Intelligence Corps has to convert this first impression, this empty page, into a picture, built up line by line, dot by dot, of the universe of activities that are going on out there. Its first and easiest task is to mark out correctly the place where every enemy unit is, each division, each battery, each railhead, aerodrome, field hospital and dump. Next it has to mark each movement of each of these, the shiftings of the various centres of gravity, the changes in the relative density and relative quality of troops and guns at various sectors, the increase, at any sector, of field hospitals, the surest harbingers of heavy attacks. The trains on all lines must be counted, their loads calculated. Next must be known in what sort of spirits the enemy is, in the field and also at home. Do the men believe in their officers? Do the men get confident letters from their civilian friends? Do they send cheerful ones back? Is desertion rare and much abhorred? Or so common that men are no longer shot for it now? So you may go on enumerating until it strikes you that you are simply drifting into an inventory of all the details of the enemy’s wartime life, in the field and at home. And then you understand.
For what you want to know, in order to beat him, is no less than this—to see him steadily and see him whole. In the past we have talked of information “of military value” as distinct from other information. But all information about either side is of military value to the other. News of the outbreak or settlement of a strike in a Welsh coalfield was of military value to Ludendorff. News of the day’s weather in Central Europe was of military value to Sir Douglas Haig. News of anything that expressed in any degree the temper of London or Berlin, of Munich or Manchester, helped to eke out that accurate vision of an enemy’s body and mind which is the basis of success in combat. A black dot, of the size of a pinhead, may seem, when looked at alone, to give no secret away. But when the same dot is seen, no longer in isolation, but as part of
