Commencing early in 1918, the subsection contributed to the confidential _Weekly Intelligence Summary_ specially written articles dealing with particular phases of the economic situation in various countries, such as “_Germany’s Raw Materials_,” “_The Food Supplies of Germany_,” “_Turkish Finances_,” and the like. These articles, which were frequently accompanied by specially prepared maps, tables, and diagrams, were all of a confidential nature, and were of great importance to a complete understanding of the strategic situation and its constantly shifting phases. The signing of the Armistice naturally brought about a sudden change in the nature of the subsection’s work, its articles becoming more monographic in character and dealing with conditions from all points of view but with particular reference to the future. Such articles included “_The Coal Situation in Germany_,” which was a detailed account of Germany’s use of the coal-fields which she occupied during the war; “_The Left Bank of the Rhine_,” being a comprehensive study of this territory from the view-point of the effect which its neutralization would have on the future of Europe; “_Economic Resources of Czecho-Slovakia_,” with a valuable map of railroads and mineral deposits in that newly born nation; “_Palestine_,” with an account of the resources, railroads, and prospects of the “State of Zion”; “_Baltic Ports_,” a monograph which showed the necessity of developing these ports and their hinterlands for the development of Russia. Upon the despatch of the American expedition to Siberia, the Economic Subsection produced a weekly economic report on Russia, with particular reference to the Asiatic territories, which was regularly forwarded to the commander of the expedition at Vladivostok. There were also prepared for the use of our forces in Siberia monographs on the food and raw-material resources, the communications, the industries, and the finances of Russia, these proving of enormous value to the staff of the expedition, which was operating in a region of which next to nothing was known save by a handful of scientists and explorers. Among the countless other reports prepared by the subsection perhaps the most important was the one on the fortifications and the territory surrounding the great German stronghold of Metz, which, had the war continued, would have been attacked by our forces. The completeness and exactitude of the information contained in this report, which was verified by persons familiar with the fortress and its environs, would, I imagine, have given the chiefs of the German Intelligence Bureau some very uncomfortable nights, had they known of its existence.
