has an opportunity to delve into the files of the German Intelligence Bureau, however, I imagine that he will find ample evidence that the showers of leaflets falling from the blue played no inconsiderable part in the collapse of the German war-machine. But, whatever the results of our efforts in this direction, as revealed by the light of history, the American people can be assured that never was a campaign of propaganda waged with such scrupulous regard for the truth. Though certain of our allies sent out material for distribution over the enemy lines which took considerable liberties with the truth, to put it mildly, and though the French quite frankly made use of Bolshevistic arguments, appeals, and promises, the distribution of our own propaganda leaflets was delayed time after time in order that the General Staff might sift and weigh the statements which it contained until they contained nothing save sincerity and truth. In the weeks that followed Foch’s great offensive in the summer of 1918, it became increasingly apparent to those who were in a position to judge, that German morale, both in the heart of the empire as well as at the front, was imperceptibly but none the less steadily deteriorating. No one realized the significance of this to the Allied cause better than the chief of the Psychologic Subsection, who determined to watch the progress of the movement, just as a physician watches the progress of a disease, and to indicate its trend by means of a chart, like those on which nurses record the variations in the pulse and temperature of their patients. In pursuance of this plan, which was put into execution about the 1st of September, 1918, a daily report was prepared which contained in brief form all news in any way relating to German morale which had come in from all sources during the preceding twenty-four hours. At the end of each week an interpretation of the drift of these news items was attempted in a weekly report. Using as a basis for its estimates material contained in these reports, supplemented by information obtained from every source open to Military Intelligence, the subsection worked out its famous “Chart of German Civilian Morale,” which, during the closing months of the war, occupied a conspicuous place on a wall of Secretary Baker’s office. The chart was drawn on a sheet divided into cross-sections, each of which represented a day, while the heavy black line, writhing across the paper like a dying serpent, showed the wavering morale of Germany’s civil population. Secondary lines depicted in graphic form the German military situation, the degree of political unity in Germany, the situation in Austria-Hungary, the state of the food supply in the Central Empires, and the U-boat sinkings. But it was, of course, the line indicating the state of civilian morale which most accurately gauged the situation. Starting in August, 1914 (nearly three years before our entry
