From July, 1918, until the day of the armistice, our flotilla at this point kept constantly at work; and the reports of our commanders show that their sound contacts with the enemy were very frequent. There were battles that unquestionably ended in the destruction of the submarines; just how much we had accomplished, however, we did not know until the Austrians surrendered and our officers, at Cattaro and other places, came into touch with officers of the Austrian navy. These men, who showed the most friendly disposition toward their American enemies, though they displayed the most bitter hostility toward their German allies, expressed their admiration for the work of our subchasers. These little boats, the Austrians now informed us, were responsible for a mutiny in the Austrian submarine force. Two weeks after their arrival it was impossible to compel an Austrian crew to take a vessel through the straits, and from that time until the ending of the war not a single Austrian submarine ventured upon such a voyage. All the submarines that essayed the experiment after this Austrian mutiny were German. And the German crews, the Austrian officers said, did not enjoy the experience any more than their own. There was practically no case in which a submarine crossed the barrage without being bombed in consequence; the _moral_ of the German crews steadily went to pieces, until, in the last month of the war, their officers were obliged to force them into the submarines at the point of a pistol. The records showed, the Austrian high officers said, that the Germans had lost six submarines on the Otranto barrage in the last three months of the war. These figures about correspond with the estimates which we had made; just how many of these the British sank and just how many are to be attributed to our own forces will probably never be known, but the fact that American devices were attached to all the Allied ships on this duty should be considered in properly distributing the credit.
