26 Fourth quarter (to date of Armistice) ...

6 It will be seen from the foregoing figures for 1917 and 1918 that the full result of the anti-submarine measures inaugurated in 1917 and previous years was being felt in the last quarter of 1917, the results for 1918 being very little in advance of those for the previous half-year.
According to our information, as shown by the figures given above, the Germans had completed by October, 1918, a total of 326 submarines of all classes, exclusive of those destroyed by them in November at Bruges, Pola and Cattaro.
Admiral von Capelle informed the Reichstag Committee that a total of 810 was ordered before and during the war.

It follows from that statement that over 400 must have been under construction or contemplated at the time of the Armistice.
It is understood that the number of submarines actually building at the end of 1918 was, however, only about 200, which perhaps was the total capacity of the German shipyards at one time.
At the risk of repetition it is as well to repeat here the figures giving the quarterly losses of merchant ships during 1917 and 1918, as they indicate in another and effective way the influence of the anti-submarine measures.
These figures are: 1917 British.
