But they did not succeed even in attacking a single east-bound troopship. The only result accomplished was the one which, from what I have already said, would have been expected; the removal of the submarines from the commercial lane caused a great fall in the sinking of merchant ships. In August, 1918, these sinkings amounted to 280,000 tons; in September and October, when this futile drive was made at American transports, the sinkings fell to 190,000 and 110,000 tons. Too much praise cannot be given to the commanders of our troop convoys and the commanding officers of the troop transports, as well as the commanders of the cruisers and battleships that escorted them from America to the western edge of the submarine zone. The success of their valuable services is evidence of a high degree not only of nautical skill, judgment, and experience, but of the admirable seamanship displayed under the very unusual conditions of steaming without lights while continuously manoeuvring in close formation. Moreover, their cordial co-operation with the escorts sent to meet them was everything that could be desired. In this invaluable service these commanding officers had the loyal and enthusiastic support of the admirable petty officers and men whose initiative, energy, and devotion throughout the war enabled us to accomplish results which were not only beyond our expectations but which demonstrated that they are second to none in the world in the qualities which make for success in war on the sea. On the whole, the safeguarding of American soldiers on the ocean was an achievement of the American navy. Great Britain provided a slightly larger amount of tonnage for this purpose than the United States; but about 82 per cent. of the escorting was done by our own forces. The cruiser escorts across the ocean to France were almost entirely American; and the destroyer escorts through the danger zone were likewise nearly all our own work. And in performing this great feat the American navy fulfilled its ultimate duty in the war. The transportation of these American troops brought the great struggle to an end. On the battlefield they acquitted themselves in a way that aroused the admiration of their brothers in the naval service. When we were reading, day by day, the story of their achievements, when we saw the German battle lines draw nearer and nearer to the Rhine, and, finally, when the German Government raised its hands in abject surrender, the eighteen months' warfare against the German submarines, in which the American navy had been privileged to play its part, appeared in its true light--as one of the greatest victories against the organized forces of evil in all history.
