Two airships brought down in flames off the east coast, November 27-28. Another list, based on an article published in the "Journal of the Proceedings of the United States Naval Institute," yields a total of thirty-eight Zeppelins as having been destroyed since the outbreak of the war. Of this number the loss of thirty was said to have been authenticated. Of the larger total (38) 5 were destroyed in 1914, 17 in 1915, and 16 in 1916. Of these 4 were lost in France, 6 in Russia, 7 in Belgium, 7 in England, 1 in Denmark, 1 in Norway, 1 in the Balkans, 5 in the East, and 6 in Germany. No further activities of Zeppelins were reported during January, 1917, except that it was announced unofficially on January 3, 1917, that two Zeppelins had been destroyed at Tondern, Schleswig, by a fire due to defective electric wiring in a recently constructed double shed. To sum up the losses in aeroplanes incurred by the various belligerents during the six months' period, August, 1916, to February, 1917, is practically impossible. Figures are available for a few months only, and they are not only unofficial, but come from all kinds of different sources, most of them very much biased. Furthermore, there always is a wide discrepancy between figures published by adherents of the Allies and those published by the friends of the Central Powers. As an example of this condition the following may well serve: At the end of January, 1916, an unofficial statement claimed that the Germans lost during 1916 on the western front a total of 221 aeroplanes. The French authorities immediately claimed that they had knowledge of 417 German aeroplanes which had been shot down by their aviators, and that 195 more machines were brought down damaged, of which undoubtedly a number finally were to be considered lost to the Germans. Neither statement, however, is supported by sufficient data to allow any kind of checking up. The truth, therefore, must be sought somewhere around the average between these two figures. Equally difficult is it to arrive at any definite figures regarding the losses in man power incurred by the various aviation corps. No official figures are available except the lists of casualties published in aviation papers. These, however, cover only the French and English organizations, and even in these two cases they contain a large number of men who lost their lives not at the front, but in aviation camps in England or France while being trained. However, that section of the French Aviation Corps containing American volunteers has been more liberal in publishing statistics. On November 3, 1916, it was announced that the flying unit of the French Corps, consisting entirely of American volunteers, had brought down between May and November a total of twenty-one German machines. At that time it consisted of twelve American members. Unfortunately it had lost previously to this date two of its members.
