As to Americans in Europe not in the military services, it is the greatest pleasure to say that, both in official and in private life, they are intensely patriotic and loyal, and have been invariably sympathetic and helpful to the Army. [Sidenote: Heroism of the officers and the men in the line.] Finally, I pay the supreme tribute to our officers and soldiers of the line. When I think of their heroism, their patience under hardships, their unflinching spirit of offensive action, I am filled with emotion which I am unable to express. Their deeds are immortal, and they have earned the eternal gratitude of our country. * * * * * No one doubted the efficiency of the navy or of its capacity to carry on its operations in a way worthy of the traditions of the American Navy. What the navy did during the war, and how it did it, is summarized in the following report by its chief. THE AMERICAN NAVY IN EUROPE EXTRACTS FROM REPORT OF ADMIRAL H.T.
