It was a commonplace of the old diplomacy that the most effective way to deceive a rival diplomatist was to tell him the truth, and similar conditions enabled the Germans to delude the British public if not the British Government, so general was the conviction that the Germans would not or could not say anything that was not false. This simple-minded attitude towards our enemies made it easy for them to combine virtue with efficiency, and German statesmen were at times singularly candid in the estimates they published of the situation. One of these truthful pictures was drawn by the German Chancellor in December 1915 when he pointed out that it was not in Germany's thoughts or interests to seek further conquests for her arms: the more territory they conquered, the thinner would be their lines and the greater the difficulty of maintaining them. But patriotic imagination detected behind this apparent frankness a design to conquer Egypt and India, or at least to dominate the Persian Gulf, and averted attention from the probability that it implied a desire to substitute a solid decision in the West for territorial speculation in the East. Nothing, indeed, was more certain than that Germany, having temporarily freed herself and her allies from danger in the East, would recall her attention to these enemies in the West by whose defeat alone could she hope to win the war; and before the end of 1915 there were rumours of the transport of German guns and troops from the East to the Western front.
